2. WHAT IS Food spoilage Food spoilage refers to the process by which food deteriorates to the point where it is not edible to humans or its quality becomes unacceptable This process can affect the food's taste, smell, texture, and appearance. These microbes break down food components (like proteins, fats, and carbohydrates), producing off-flavors, odors, gases, and toxins. Enzymes naturally present in food can cause chemical changes. Oxidation of fats leads to rancidity Light, heat, moisture, and air can accelerate spoilage.

3. Signs of Spoiled Food Unpleasant odor Slimy or mushy texture Discoloration Gas formation (bloating of packaging) Mold growth Sour or bitter taste

4. INDIA: 2023 SCHOOL LUNCH POISONING (BIHAR) WHAT HAPPENED : Spoiled rice contaminated with pesticides served in a school meal. IMPACT : 50+ children hospitalized, many critical. CAUSE : Improper food storage and possible pesticide contamination.

5. CHINA: 2008 MELAMINE MILK SCANDAL WHAT HAPPENED : Milk and infant formula were adulterated with melamine (a toxic chemical) to fake higher protein levels. IMPACT: 300,000+ babies sickened, 6 deaths, 54,000 hospitalized with kidney damage. CAUSE: Deliberate contamination to cut costs, but also poor food safety controls.

6. JAPAN: 2000 SNOW BRAND DAIRY STAPH POISONING WHAT HAPPENED : Milk products contaminated with Staphylococcus aureus. IMPACT : 15,000+ sick, company nearly collapsed. CAUSE: Power outage led to spoiled milk being reprocessed.

7. Objectives Prevents Foodborne Diseases Reduces Food Waste Cost-Effective & Scalable Real-Time Monitoring & Alerts Works with Multiple Food Types Supports Smart Kitchen & IoT Integration

8. APPLICABLE School/College Canteens & Midday Meal ProgramsProblem : Mass food poisoning cases (like Bihar's 2023 incident). Restaurants & Cloud KitchensProblem : Spoiled ingredients causing customer illnesses. Supermarkets & Grocery StoresProblem : Hidden spoilage in packaged foods. Food Storage WarehousesProblem : Temperature/humidity fluctuations ruining stocks. Agricultural Cold ChainsProblem : Post-harvest losses (30-40% in developing nations).

9. WORKING 1.MQ135 Gas Sensor Detects harmful gases (ammonia, CO₂, benzene) released during food decay. 2.pH Sensor Measures pH changes in food (meat, dairy, fruits). 3.TV Biosensor Detects microbial growth in the food. 4.TCS3200 Color Sensor Detects color changes,Uses RGB values to identify spoilage patterns 5.Arduino IDE Used to program the microcontroller for sensor data collection.
