FOOD TECHNOLOGY

Detailed explanation-1: -LBV foods: peas, beans, nuts, lentils, cereals (rice, oats, barley, rye, millet, sorghum) and cereal products (bread, pasta), seeds and gelatine. Protein alternatives are manufactured food products, with a high protein content, e.g. mycoprotein (Quorn), tofu, TVP and tempeh. They are used instead of meat in meals.

Detailed explanation-2: -Low biological value (LBV) proteins are missing one or more of the essential amino acids we need. They’re only found in plant sources e.g. peas, lentils, nuts, seeds and most beans, and in smaller amounts in vegetables like spinach and broccoli.

Detailed explanation-3: -Protein complementation is when two LBV proteins are eaten together. By eating two LBV proteins in the same meal, you can make up for the lacking amino acids in each, therefore giving yourself a meal with a high biological value (HBV). A common example of protein complementation would be eating beans on toast.

Detailed explanation-4: -In general, animal sources, such as meat, poultry, fish, eggs, milk, cheese and yogurt, have higher biological value proteins, while plants, such as legumes, grains, nuts, seeds and vegetables, provide low biological value proteins.
