Storage ,prep & Cook Flashcards
What’s the storage of vitamin A & how to reduce loss ?
Vitamin A found in fatty foods & may be lost due to oxidation & exposure to light & store in fridge , cover foods in dark containers away from light
What is storage of vitamin b1(thiamine ) & how to reduce loss ?
Exposure to light & uv light reduces thiamine content & store away from light
What is storage of vitamin b2(riboflavin) & how to reduce loss ?
Deteriorates quickly to exposure to uv light & espically in supermarket chill cabinets & store away from sunlight (dark conditions) & avoid goods stores for length of time in brightly lit supermarkets in display cAbinets
What is the storage of vitamin b3(niacin) & how to reduce loss ?
Some loss due to oxidation & avoid storage of possible
What is storage of vitamin c & how to reduce loss ?
Vitamin c lost due to oxidation & exposure to air changes chemical structure of vitamin c resulting in the body not being able to use vitamin c & brushed fruit & veg lose vitamin c due to enzyme action & oxidation & reduce by buying fresh as possible & store in fridge at low temp as possible as slows down oxidation & store away from light & avoid brusing or damage before storage & avoid buying read prepared products as more likely to suffer nutritious loss
What is the preparation of vitamin b complex & how to reduce ?
Vitamin b found in bran of cereal & when wheat is killed to produce white flour white bran is removed resulting loss of vit b & white rice is usally polished to remove bran & results vitamin b being lost & to reduce loss by buying whole grain bread or brown rice
Preparation of vitamin c & how to reduce loss ?
Vitamin c is a water souble & can easily be leached into any liquid & exposure to light reduced vitamin c content through oxidation & peeling exposes the surface to air speeding up oxidation & reduce loss by avoid soaking & don’t prepare far in advance & avoid peeling if possible or peel thinly as most vitamin c is under skin & use acids such as lemon juice to slow down loss of vitamin c through oxidation
What is cooking of vitamin b complex & how to reduce loss ?
Vitamin b is stable in tempetures up to boiling point & grauduly destroyed if heated above boiling point for long period of time & folic acid is a water souble vitamin & destroyed by prolonged cooking & reduce loss by quick methods of cooking such as steaming , stir frying ,microwaving & pressure cooking to preserve the vitamin
Cooking of vitamin c & how to reduce loss ?
Vitamin c destroyed by low temps , lost through leaching in water , prolonged cooking leads to vitamin c being lost through leaching or exposure to air & can be lost through reheating foods & reduce loss by add to boiling water & cook for minimum time & use as little water as possible to prevent loss through leaching & choose cooking methods such as stir frying , microwaving to reduce loss & cook short period of time & serve immediately
