effects of food processing on micronutrients Flashcards
how does food processing affect micronutrients
many nutrients can be destroyed or removed
what are the vitamins that are most likely to get destroyed
folate thiamine and vitamin C
what are the vitamins that are most likely to hold their nutrient profile
vitamin B3, Vitamin K, vitamin D, vitamin B7 and vitamin B5
what is blanching
scalding vegetables in boiling water or steam for a short time. It is typically followed by quick, thorough cooling in very cold or ice water. Blanching stops enzyme actions which otherwise cause loss of flavor, color and texture.
what is dehydrating
Drying out foods such as fruits can reduce the amount of vitamin C they retain, but it can also concentrate other nutrients, particularly fibre in plant foods. Dehydrating food also makes food products more energy dense, which may contribute to weight gain.
what can be done to retain the nutrient value of foods
wash or scrub vegetables rather than peeling, store foods properly, use fresh ingredients,
what happens to the nutrient profile of a food when frozen
the nutrient value of a food is retained when it is frozen. Any nutrient losses are due to the processing prior to freezing and the cooking once the frozen food is thawed.
