Study Notes

Food Processing and Preservation

Food processing transforms raw materials into other food products.
Preservation prevents spoilage, maintains color, taste, and enhances shelf life and nutritional value.
Main goals of food processing include extending shelf life, satisfying consumer tastes, creating food varieties, and accommodating a growing population.

Food Production in India

India ranks as the second-largest producer of fruits and vegetables globally.
Approximately 18% of production is wasted annually, according to CIPHET data.
Post-harvest management is crucial for minimizing waste and maintaining product quality, and includes processes like cleaning, cooling, sorting, and packaging.

Classification of Foods by Perishability

Perishable Foods: Spoil quickly (1-2 days), including meat, fish, poultry, most fruits, and vegetables.
Semi-Perishable Foods: Can last 1-2 weeks when properly stored; examples include onions, potatoes, and garlic.
Non-Perishable Foods: Generally last up to a year without spoiling unless mishandled.

Food Spoilage

Food spoilage leads to deterioration in safety, sensory quality, or nutritional value.
Damage renders food unsuitable for human consumption.

Types and Causes of Food Spoilage

Types of Spoilage:
- Microbial spoilage
- Enzymatic spoilage
- Chemical spoilage
- Physical spoilage
Causes of Spoilage:
- Insects, parasites, and rodents
- Temperature variations (both heat and cold)
- Moisture, light, and time
- Reactions with oxygen

Bacterial Growth Conditions

Bacteria may have different shapes:
- Spherical (cocci)
- Cylindrical (bacilli)
- Spiral (spirilla, vibrio)
Favorable conditions for bacteria growth include:
- Moisture (some require anaerobic or aerobic environments).
- pH levels around 6 to 8 for optimal growth.
Bacterial spores are more resistant to processing conditions than yeast or mold spores.
