Key Points
Definition of Food Processing.
Food processing transforms raw ingredients into finished products for consumption.
What is Food Technology?
It's the application of science to food processing, improving safety, quality, and sustainability.
History of Food Processing.
Canning by Nicolas Appert in 1810 highlighted initial advancements in food preservation.
Pasteurization explained.
Developed by Louis Pasteur, it's critical for killing harmful bacteria in foods like milk.
Significance of Food Processing.
Enhances shelf life, safety, taste, and nutrient retention, catering to diverse consumer needs.
Classes of Foods by Perishability.
Perishable (milk), semi-perishable (fruits), and non-perishable (grains) foods differ in shelf lives.
Food Fortification definition.
Adding nutrients to improve food quality; e.g., iodized salt, fortified flour.
Role of Food Scientists.
They study food properties and processes to enhance safety and nutrition in food products.
Basic Food Preservation Methods.
Traditional methods include drying, fermentation, salting, and pickling to prevent spoilage.
Microorganisms in Food Spoilage.
Bacteria, fungi, and yeasts are primary causes of food spoilage and require control measures.
Danger Zone temperature range.
Bacteria thrive between 5–60°C; maintaining proper storage temperatures prevents spoilage.
Understanding Food Manufacturing.
It's mass production using food technology principles to meet consumer demand.
Minimally Processed Foods.
Foods like washed vegetables retain freshness through minimal processing for market readiness.
Manufactured Foods vs. Preserved Foods.
Manufactured foods (like jams) undergo significant changes, while preserved foods maintain basic characteristics.
Functional Foods meaning.
Foods providing health benefits beyond basic nutrition, such as probiotics in yogurt.
Role of HACCP.
Hazard Analysis Critical Control Points ensures safety in food production by identifying risks.
Career opportunities in Food Tech.
Various roles like quality assurance, research, sales, and entrepreneurship are available in the sector.
Self-employment in Food Processing.
Small-scale ventures like jams or pickles can be profitable, supported by government incentives.
Nutritional Concerns in Food Tech.
Modern processing aims to enhance nutritional quality, addressing health issues like obesity.
Importance of Good Manufacturing Practices.
These practices ensure product safety, quality, and compliance with health standards in production.
