Additional Practice Questions
What are the factors influencing microbial growth in food, and how does food processing help in controlling these factors?
mediumAnswer: Microbial growth in food is influenced by nutrient availability, moisture, pH, oxygen levels, and inhibiting substances. Food processing controls these factors through methods such as heat application, moisture reduction, temperature control, pH reduction, and oxygen control, thereby preventing spoilage and extending shelf life.
Discuss the role of food fortification in addressing nutritional deficiencies in staple diets.
mediumAnswer: Food fortification involves adding essential nutrients that are lacking in staple diets to prevent deficiency disorders. Examples include iodised salt, folic acid added to flour, and vitamins A and D added to milk and oils. This ensures that dietary requirements are met, promoting better health outcomes.
Describe the historical development of food processing technologies.
hardAnswer: Food processing technologies have evolved significantly from prehistoric methods like sun drying and fermentation to modern techniques such as canning, developed by Nicolas Appert in 1810, and pasteurization by Louis Pasteur in 1864. These advancements have improved food safety and storage, catering to changing consumer demands.
What is the significance of packaging in food processing, and what are the key considerations?
mediumAnswer: Packaging plays a crucial role in protecting food products from contamination, preserving quality, extending shelf life, and providing convenience. Key considerations include the material used, which should maintain food safety, be durable, and be cost-effective while also satisfying consumer preferences.
Explain how food processing contributes to sustainability in the food industry.
mediumAnswer: Food processing enhances sustainability by reducing food waste through improved preservation methods, utilizing all components of raw materials, and promoting eco-friendly packaging solutions. It also supports efficient resource use and minimizes the environmental impact of food production.
