CHAPTER 1
INTRODUCTION
1.1
Food Processing Industry and Cocoaland Industry Sdn Bhd.
The food processing industry is the industry that undergoes the physical or chemical transformation of raw ingredients into food or of food into other forms. It combines raw food ingredients to produce the consumer food products that are prepared and served.
In Malaysia, the food industry is diverse with a wide variety of processed foods, the industry contributed around 10% of the country’s manufacturing output in these few years and the global sales in food products are projected to grow at an annual rate of 4.8% by 2020.
Besides that, the halal industry in Malaysia offers enormous opportunities for Malaysian manufacturers. With more than 2 billion global Islamic population, the market for halal food can be estimated at more than US$500 billion per year. The idea of hala is associated with food products that are of high quality as in cleanliness, sanitation and compliance with religious requirements.
Cocoaland Industry Sdn Bhd., located in Rawang, Kepong is the principal manufacturing arm of the Cocoaland Holding Gorup, manufacturing mainly chocolates, hard candy, soft candy or gummy, cookies, wafer, snack and beverage. The industry began with two brothers started out as small time vendors were later joined by other brothers and moved upstream in their business activities in order to 1
benefit from higher margins. Firstly, Mite Food Enterprise Sdn. Bhd. was formed in 1980 as a manufacturing and distributing company. Success finally came in the mid1980s when they successfully identified a market opportunity for the manufacture of polytubed drinks, which enable the company to venture into the overseas market for the first time, exporting to Middle East, and purchase their own factory. In Year 1991, they successfully set up 2nd factory in Kepong and commercialized “Koko Jelly”, and in year 1995, they have set up the 3rd factory in Rawang. Cocoaland Industry has then set up another factory and launched beverage products on year 2010.

1.3
QA/QC Department
Quality assurance (QA) is to ensuring the quality in the processes by which products are developed while quality control (QC) is to ensuring the quality in products and identifying defects in the actual products produced.
Most of the companies especially the manufacturing industries will set a department for quality assurance, but it is rarely find that a company set a department for quality control. The quality control department usually will be a sub-department for the production department or quality assurance department.
QA aims to prevent the defects with a focus on the process used to make the product, it is a proactive quality process. They establish a good quality management system and the assessment of its adequacy along with a periodic conformance audits of the operations of the system to improve development and test processes so that defects do not arise when the product is being developed. They do prevention of quality problems through planned and systematic activities such as documentation, planning, operational excellence and etc. Examples of QA tasks are such as verification of the system, issues corrective action report, system or process auditing, issue and update specification list and issue and update process checklist.
QC is a reactive process, they aims to identify and correct if is needed the defects in the finished product. They finding and eliminating sources of quality problems through tools and equipment so that customer’s requirements are continually met. Examples of QC tasks is validation, sorting, lab testing, approves conformance ingredients or finish goods and inspection.

Figure 1.4.2 Sub-departments of QA/QC department
Figure 1.4.2 shows the sub-departments of QA/QC department in Cocoaland Industry Sdn. Bhd. There are 4 sub-departments in total, each sub-department will be assigned a QA executives to be the head of department, however some of the sub departments will have multiple team which is according to the production line, such as lot 100 have an inprocess team, lot 5 have another inprocess team, lot 88 have total 5
of 4 inprocess teams. Each team will have the QA executives to be the team leader, and these teams task will report directly to the assistant manager or manager.
The incoming department in charges of inspecting the condition and specification of the raw material such as shelf-life, sugar level and etc and packing material such as art-work, colouring, barcode and etc. The dispensary department will dispensed the unpack/separates raw material in the correct amount to the production. The incoming department usually inspect before the production run.
The inprocess department inspect and in charge of the condition of the goods when the production is running. The online QC will inspect and check the condition of the production line, machine, raw ingredients that are ready to cook, environment condition (temperature and humidity) of the production line. The finished good will collect the sample of finish good (including after shipper packing) and inspect.
Testing department will in charge all the testing of the products. Chemistry test will perform average weight specification, total acidity, moisture analyser and reducing sugar, whereas microbes will test the microbiology specification of the products, such as yeast. Retention will in charges of keeping the finished goods to some rooms with different temperature such as room temperature, fridge or warehouse, and then will test its stability properties after some period, usually will test when the goods is in the mid life of its shelf life, and after its expired. For example if the shelf life of LOT 100 Mango Gummy is 3 years, then the test will perform on 1.5 years after the goods is produced and after the goods is expired.
Due to all the tasks are related to QA/QC department, the compliance is actually temporary be the sub-department of the QA/QC department, the company will soon established this sub-department to be a new department. The compliance department in charges mostly documentation, handling customer complain, and dealing with auditor. Some other companies will usually have the compliance department as the sub-department of QA departments.

CUSTOMER
Figure 1.5.1 The process flow of the goods
Figure 1.5.1 shows how the products is produce and send to the customers or markets. The figure also shows the overview relations between departments. Supply chain first will arrange the shipment and also the demand of the customer and create the shipment planning to the production. Production department will verify and plan again whether they are capable to produce according to the planning of supply chain department. Then the production will discuss and issued production planning along with the work order formulation from RnD department to purchasing and store department. Purchasing department will purchase the raw material that are going to supply and produce and send to the store. Store will always ensure the amounts of raw material in the store is always right, then will send the correct raw material to the production department. Production department will produce goods from all these raw material and store the finished goods to the store. The finished goods are then supply to the customer or markets according to supply chain planning. Human Resources and Maintenance departments is to ensure the process flow runs in a steady condition, which is manpower and also the condition of the machine 7
However, even though the flow runs smoothly, there are still many question about the flow. These question are such as: a. Is the production giving the correct production planning and work-order formulation to the purchasing and store? b. Is the formulation that issued by the RnD is an approved or safe-toconsume formulation? c. Is the purchasing buying the correct type of raw material? d. Is the Raw Material supplier supply the correct raw material and in a good condition? e. Did the Store gives the correct raw material or ingredients for the production to produce? f. Is the production line runs smoothly? g. Is all the properties, physically, chemical or biological of the goods produced by the production is the always remain the same? h. After the production ends, did the production line cleaning such as hot flush or caustic soda clean the line in a safe and clean condition? i. Is the condition of the stores affects the properties of the item store? j. Is the human resource hire the correct professionals to the correct demand of the department? k. Is the maintenance repair or service the line in a correct steps or frequency? l. If customer complains about the product, who are going to deal with the customer and investigate for who to blamed?
All these questions above will affects the quality of the finish goods and it might get more customer complaints and worst is get summon from the government body such as ministry of health. Thus, QA/QC department is needed to answer all the questions above. QA/QC departments will ensure, investigate, monitor, control and issues Corrective And Preventive Action Report (If is needed).

Figure 2.1.1 Process flow chart for New Soft Candy
9
Figure 2.1.1 shows the process flow chart of the New Soft Candy. When the raw material has been issues and ready to be process, the production worker will put all the ingredients/raw materials into the input tank. The raw material or feeds will then transfer to the dissolving tank by solid pneumatic conveyor, then weighing and mixing all the different type of raw materials. Then tempering the mixture into a slurry form. The slurry is then to the cooking process in a CCP temperature and then to the vacuum tank to undergoes air inflation.
When the slurry has done vacuum, it will in the buffer process and then filtration process with CCP pressure applied. The filtered slurry will now mixed with colour, flavour and juice. Then deposits the slurry to the moulded corn starch for shape moulding. Then along with the moulded corn starch tray and the slurry in it, they will transfer to the drying room for drying process. This drying process takes usually 2 to 4 days depends on the properties of the slurry and also the raw materials used, as long as the slurry is fully dried in the gummy shape, it can be taken out for the destarching process.
The de-starching process will seperates the corn starch with the moulded dried gummy, it is then undergoes the coating process, the coating process can be oil coating, sugar coating, acid coating or mixture of some of these components. When the coating is done, it will be transfer to another drying room for the 2nd drying process to make sure the coated layer is stick with the gummy.
The gummy is now ready for the packing process. Some of the gummy will have an inner packing, a packing which is pack the soft candy each one by one. Then only to the outer packing, which is a packing direct to the customer, or the packing that the soft candy is ready to sell in the market, some of the products will skip the inner packing and directly to the outer packing, it depends on the type of products. After outer packing, the goods will be manually into display box packing and then shipper box packing, some of the goods will skip the display box packing.

Online QC for LOT 100 New Soft Candy
As mentioned in section 1.4, the online QC inspect and check the condition of the production line, machine, raw ingredients that are ready to produce and environmental condition of the production line. All the results that inspect will recorded to the online QC form, and the executives or supervisor will analyse the recorded form frequently to make sure things runs well, or as a better book keeping in case easy to be refer and find the cause when customer complains about the quality of the finish goods. Inspection must be perform at least 3 times per shift, usually morning, after lunch and after tea break for the QC checker who is morning shift.
11
The Online QC checker will firstly inspects and record the raw material is correctly issued by the store and dispensary department according to the recipe checklist. The recipe checklist can be refer to Work-Order or the previously batch manufacturing record. Then visual check the raw material is added into the correct feed tank before during the dissolving/weighing/tempering process. When is cooking, check and record the cooking temperature, which is the first CCP for producing the soft candy, the CCP temperature range between 103℃ to 108℃ .
Figure 2.2.1 Refractometer for measuring the brix level
Then collect the sample with a table spoon from the vacuum and cooking tank and test the brix with brix meter also known as refractometer, is a simple optical instrument that measure the amount of light refracted in a liquid, it measure on a “Brix” scale and usually used for measuring the brix level of fruits and vegetables, wine, sugar, carbonated beverage, juice and honey. The brix level is very important because it is a great indicator or specification of flavour and quality of the products. Brix is the sugar content of an aqueous solution. 1 ° Brix is equal to 1 gram of sucrose in 100 grams of solution, it is also the strength of the solution as percentage by mass. If the solution contains dissolved solids other than pure sucrose, then the brix only approximates the dissolved solid content. Brix test also perform for the buffer process, moulding and depositing process and also 1st drying process.
Inspect the pressure of filtration and condition of filter before and end of production. Ensure the filter is intact, not torn and no foreign objects are observed, inform the production or QC supervisor when the condition does not met.
Visual check and record the colour, flavour and juice raw material for the mixing process, collect the sample of the slurry and check whether the colour of the slurry meets the specifications and check all the raw materials are mixed homogenously. 12
Inspect and verify the mould used is correct as per stated in the BMR, then check the moisture content of corn starch. The moisture of the corn starch can only be maximum 7% of the moisture content.
Check and record the temperature and relative humidity of dry room, these parameter can be obtained from the thermohygrometer. Report to the QC supervisor or Production Supervisor if the drying room temperature or relative humidity is out of the specification.
Visual check the product after de-starching and coating process. Make sure the sorting run wells after de-starching and coating process and before packing process. Sort out the gummy which is: a. Deformed Shape b. Too obvious protrusion c. Mixed-colour pastilles d. Deformed shape, mixed colour and oversized e. Tailing f. Tail less g. Corn Starch Lump h. Air bubbles trapped i. Either combination of the above conditions
Inspect the sealing quality and wrapper alignment of the inner packed gummy. Inspect the compressed air blower to remove empty wrapper is still functioning or not. For other packing, inspect the metal detector is functioning by putting sample Ferrous, Non-ferrous and Stainless Steel stick into the conveyor. Inspect and record the weight of the outer packed goods are in the specification, the batch number and expiry date is properly labelled.

CHAPTER 3
OPERATIONAL EXCELLENCE
3.1
What is Operational Excellence?
Operational excellence is a project that problem-solving, teamwork, and leadership results in the ongoing improvement in an organization. It stresses the application of a variety of principles, systems, and tools toward the sustainable improvement of key performance metrics. Besides, this projects also involves focusing on the customers’ needs, keeping the employees positive and empowered, increasing in efficiencies, and continually improving the current activities in the workplace.
3.2
Tasks of Dispensary Department
The dispensary department dispensed the “odd-out amount” according to the workorder formulation of the feed input needed to the production department before the whole production process starts. It is a sub-department of QA/QC department as it’s controls the amount of dispensed raw material and also the balance amount of the raw material for the production.
A very general example is assume to produce 20 batches of Gummy A, it needs 125 kg of Ingredients A, 278 kg of Ingredients B and 301 kg of Ingredients C for the production to run. And every unopened raw material from the supplier is 25 kg net for every ingredients. Thus, the dispensary department needs to dispense:
14
ଶ଼ ୩ ଶହ ୩
= 11.12, then 11 × 25 = 275 kg
Thus, the dispensary department needs to dispense 278 kg – 275 kg = 3 kg of ingredients B for the production then manually tied the remaining 22 kg of the undispensed but unpack raw material and store to the correct storage location.
Same method apply to ingredient C, the dispensary department will dispense 1 kg of the Ingredients C to the production department and store the ramining 24 kg of the undispensed raw material back to the correct storage location.
The lot 88 Candy Dispensary Department is just set up since year 2013 along with the lot 88 candy production plants. Thus, there are some problems, critical and also minor for this department since the year has set up. These problems are: a. Low Efficiencies, the dispensary departments always need working overtime in order to complete their tasks, however there has some worst case that is the department can’t complete their task even though overtime is given. b. Can’t see improvements or more worst although many actions has taken for the department such as hire more worker for the department, purchase more utensils and tools for the department. c. The QA/QC departments executives and managers has receives many complaints from the production department that they can’t start producing or cooking according to the production planning due to the dispensary department did not or not yet give the dispensed raw material on time, which delayed the production and may cause lost for the company.
Thus operational excellence projects is needed to overcome these problems.
3.3
Observation and Factors
After two weeks of observation, factors identify that causes inefficiency of the dispensary department are: a. Time management matters
15
i. The department doesn’t have a proper sequence for the ingredients to be dispensed. ii. The whole department rather performing single task than multitask. iii. The dispensary department will have no action around 30 minutes before lunch time and around 15 minutes before Tea Break. iv. Daily Cleaning and housekeeping takes around 1 hours to complete. b. Manpower matters i. Worker abuse OT policy and allowance ii. The department still lack of a proper person in charge. iii. Not all the workers know how to dispense all the ingredients. iv. Friday Prayer, will lack of the muslim manpower. c. Working environment i. No CCTV in some part of the department. ii. No EXT telephone line, this will gives the worker to have excuse for bring handphone to the dispensary room. d. Tools for working i. Lack of Big Electronic Scale ii. Standard
weight
location

doing
daily
calibration
performance check located at the beverage line, which takes around 40 minutes to travel. iii. Not enough Trolley. e. Ingredients matter i. Some of the ingredients is in lump form which takes longer time to break it into powder form before start dispensing. ii. Raw material that needs to be dispensed into a big amounts takes more times. iii. Some of the ingredients, especially wet ingredients such as flavour and juice can’t be dispensed too early, the maximum period for pending dispensed flavour and juice is 8 hours or else it will oxidation.
16
iv. Every dispensed ingredients need to be labelled by a handwritten sticker, this sticker is written by the dispensary department, which will delay and waste the time of one of the manpower to dispensing. f. Others Departments i. Pending for Raw Material from Store. ii. Pending for the signed Work Order iii. Sudden changes of the production planning by production department or supply chain department.
3.4
Solutions
The solutions for the identified factors above are established, they are: a. Creates a proper system for the department by generating Work Instruction for the department. This will act as a rules for the department. b. Observe and record the standard time taken for each ingredients and each cleaning action done for the department. c. Request to purchase the lacking tools that affects the efficiency of the department. d. Discuss and deal with the supply chain, production and store departments for being part of the factors that affect the efficiency of the department. e. Establish a simple program for sticker printing instead of writing. In these solutions, solution c and d will be done by the QA executives and managers.
3.4.1 Work Instruction The Work Instruction (WI) shares some similarities with the Standard Operating Procedure (SOP), both describes the tasks or jobs of the specific department. However, SOP provides what will be done and who will be responsible for making sure it gets done, where WI provides specific details on how it is done, it tends to be more specific than SOP.
Let’s take cleaning and sanitizing as an example, imagine that we are in a rooms with tables, chairs, windows, and weighing balances. In SOP, it will describe 17
we need to clean the tables, chairs, floor, windows and weighing balances with mop, wet clothes, alcohol, hot water and detergent. But in WI, it will describe we need to mop the floor every morning with detergent and hot water, wipe the windows once a week with wet clothes, wipe the tables and chairs with wet clothes and sanitize it with alcohol once a month and wipe the weighing balances with wet clothes and sanitize it before we want to use.
Thus, WI will be generated to have a more “specific rules” for the department to follow. The WI is also attached along with the cleaning schedule, amended cleaning checklist, dispensing method flow chart, balance material handling flowchart and sequence and shifts of dispensing.
With the cleaning schedule and amended cleaning checklist, the department will take lesser time for housekeeping due to not everything need to be clean daily. The flow charts will ensure all the workers in the departments know how to dispense every raw material and handling balance material. The sequence and shifts of dispensing will act as a timetable for the dispensing activities.
3.4.2
Standard Time
A standard time chart and table is generated so that the workers and also others departments know the capability for the dispensary department to finished their task. If the standard time calculation for the workload does not need OT, the department must finish their task on time, or else they will do it without get paid.
3.4.3
Sticker Writing Program
By using Microsoft Excel VBA functions, a userform is created and the sticker is ready to be printed which saves a lot of time compare to writing the sticker.

CHAPTER 4
CHEMISTRY TEST
4.1
Flavour
Test the flavour of the sample and describe it into the test sheet.
4.2
Colour
Describe the colour of the sample into the test sheet
4.3
Appearance
Describe the shape of the sample into the test sheet.
4.4
Odour
Smells the sample and describe it into the test sheet
4.5
Average Weight
Measure the weights of 5 samples, and get the mean weight. Compare the mean weight with the specification.
19
4.6
pH test at room temperature
The samples will then melt into liquid or aqueous form, or mixed with RO water (depends on the type of sample) and have a pH test with pH sensitive electrode. Record the measured pH and compare it with the specification.
4.7
Total Acidity
The aquaeuos sample will then titrate with 0.1 N NaOH the amount of the titrated NaOH to pH 8 will be recorded and calculation with the formula below: × ܂ ܟ. × × ۼ ܡܜܑ܌ܑ܋ۯቀ% ቁ : ܞ . ܔܘ܁ × ۼ. ܜ܅ T = Titrated NaOH, ml N = Actual Normality of NaOH used Spl.Wt = Weight of the sample before titration starts
Record the calculated Acidity and compare with the specification.
4.8
Moisture
There are two methods to determine the moisture content of the finished goods or sample. Firstly is the fast method, by using the moisture analyser, and with the setting time, the moisture analyser will analyser the moisture content of the sample. However, this method can be only applied to hard candy.
The second method is applied for soft candy, that is dry and melt the sample in a oven with temperature of 105℃ for 24 hours. Then compare the mass and calculate the lost on drying content with the formula below: ୠୱିୟ
% LOD = ୠୱିୠ × 100%
Where, Wbs = Weight of beaker + Sample 20
Wa = Weight of Sample After Drying Wb = Weight of Empty Beaker.
4.9 Reducing Sugar Test This test only applies to hard candy. With the aid of blender, crush the hard candy into the fine powder form. Then put about 4g of the candy powder into the beaker and mix with RO water with stirrer.
Add 5 ml of Fehling solutions A and Fehling solutions B and heat the mixture vigorously until it starts to boil (with bubbles seen). Cool the mixture with cold water then add 10 ml of Sulfuric Acids, 10% Potassium Iodide and RO water. Insert the mixture into auto-titrator to start the test.
Compare the test result with the specification.
