Low temp presentation
Chilling and freezing are methods of food preservation that use low temperatures to slow microbial growth and chemical reactions in foods. Chilling involves storage between 0-15°C to extend shelf life by retarding bacteria, enzymes, and chemical changes. Freezing at below 0°C stops nearly all microbial and chemical changes by freezing water in foods into ice crystals. Quick freezing produces smaller ice crystals and less damage than slow freezing. Both methods maintain quality attributes better than other preservation methods, though texture changes can occur. Low temperature preservation is effective for long-term storage and retains more nutrients and sensory properties compared to other techniques.

HACCP PRESENTATION.pptx
Here are the key steps to solve this problem:
1) Bacteria typically double in number every 20 minutes at room temperature.
2) In 7 hours there are 7 * 12 = 84 periods of 20 minutes.
3) Each period of 20 minutes the original bacteria doubles. After n periods of doubling, the number of bacteria is 2^n times the original amount.
4) Therefore, after 84 periods of doubling, the number of bacteria is 2^84 = 2,097,152 times the original 1 bacteria.
So the number of bacteria that will grow from 1 bacteria left at room temperature for 7 hours is 2,097,152 bacteria.
Freezing
Chilling and freezing are unit operations used to preserve foods by reducing the temperature to extend shelf life. Chilling reduces temperatures to between 1-8°C to slow microbial and biochemical changes, while freezing reduces temperatures below the freezing point of water to immobilize water and further extend shelf life. Properly chilled and frozen foods can be stored for longer periods with minimal quality degradation compared to fresh foods at ambient temperatures.

Lyophilisation- Technique, Industrial Requirement, Pros & Cons
The document discusses lyophilisation (freeze drying), which is a preservation technique used in the food industry to extend shelf life. It involves freezing the food, then reducing pressure to allow frozen water to sublimate from the food directly to a gas. This process does not damage heat-sensitive foods. The three steps are freezing, primary drying to remove 95% of water, and secondary drying to remove remaining water. A lyophilisation plant requires a drying chamber, vacuum system, cooling system and capacitors to collect water and facilitate the drying process. Freeze drying results in a very stable, lightweight product but is an expensive process best for high-quality foods.
