| Hygiene and Sanitation | Measures in industrial production (cleaning, sanitization, personnel hygiene) to prevent contamination and ensure safe food handling. (Common GMP component) LinkedIn |
| Lipid Oxidation | Chemical reaction of fats with oxygen leading to rancidity, off‑flavors, and nutrient loss; a major cause of quality deterioration in lipid‑rich foods. (Oxidative spoilage mechanism described in food chemistry) 科学直接+1 |
| Microbial Contamination | Presence of bacteria, yeast, or mold in foods that can lead to spoilage or foodborne illness, monitored by microbiological testing in industrial systems. (Standard microbiological hazard concept) MyHACCP |
| Modified Atmosphere Packaging (MAP) | Packaging technique where air inside a package is replaced with a controlled gas mixture (e.g., reduced O₂, added CO₂/N₂) to slow microbial growth and oxidation. (Widely recognized MAP definition) 维基百科 |
| Nitrogen Flushing | Replacing air with nitrogen in packaging to reduce oxidation and slow spoilage reactions. (Common packaging technique) ResearchGate |
| Oxidation‑Reduction Potential (ORP) | Measure of a food system’s tendency to gain or lose electrons; influences microbial growth, oxidation, and spoilage stability. (ORP-related redox concept in food microbiology) MyHACCP |
| Oxidative Rancidity | Spoilage of fats and oils due to oxidation, leading to development of off‑flavors and odors. (Defined rancidity and lipid oxidation process) 维基百科 |
| Packaging Materials | Materials (films, glass, cartons, barriers) used to protect food from moisture, oxygen, and light, essential for shelf‑life preservation. (Packaging protection concept) ResearchGate |
