Explain the importance and functions of quality control in the food industry.

1. 1 · Open in two lines. Quality control is the inspection and testing that checks a food meets its specifications. It works inside a wider quality assurance system.
2. 2 · Define QA and QC. QA is preventive and process-oriented; QC is detective and product-oriented. Show the difference in a small table.
3. 3 · Importance.
   • Consumer: safe, consistent food.
   • Manufacturer: less waste, fewer recalls, brand trust.
   • Government: fewer outbreaks.
   • Trade: certificates open export markets.
   • Employees: clear procedures and pride in work.
4. 4 · Draw the QC chain. [Flow: standards → raw material control → process control → finished product control → packing and storage → records and feedback]
5. 5 · Functions, with examples. Milk platform tests, jam Brix, coliform test on ice cream, cold room logs, swab tests, batch codes, staff training.
6. 6 · Kitchen link. In a hospital diet kitchen, therapeutic portions are weighed and trolley temperatures checked.
7. 7 · Close in one line. QA builds quality in; QC proves that it is there.

Scoring tip: Start with the QA vs QC difference in a small table, then spend most of the answer on the functions, each with an example.
