Lecture 4- Food chemistry- carbs and vitamins Flashcards
what is the definition of carbs
what organic compounds make up carbs
what is the formula for glucose
what is the formula for table sugar
what is the formula for starch
where does dietary CHO come from
what happens in photosynthesis
what is the equation for photosynthesis
what carbs are found in cereal grains/potatoes
what carbs are found in fruit
what index relates to the free/accessible sugar
what is starch
what is fibre
what is non-digestible by human gastric and intestinal enzymes
what does Colonic fermentation of fibre produce
explain the classification of carbs
what are monosaccharides
what are disaccharides
what are oligosaccharides
explain the source, function and characteristics of different carbs
glucose + fructose= fruits, honey
sucrose= beet and cane
lactose= milk and milk product
maltose= malt products
dextrins= hydrolysis product of starch
glycogen= meat products and seafood
cellulose= skeletal structure of plant cell (indigestible)
what are the Functions of simple sugars in foods
is starch a complex carbohydrate
what chains make up starch
what shape is amylose
what shape is amylopectin
where is starch found
is amylose a gel
is amylopectin waxy
what does the properties of starch depend on
what is the ratio of commercial starch
what plants can starch be found in
what 3 chemical reactions are related to carbs
what is Caramelisation
what is Dextrinization
what is Gelatinisation
what are 2 other browning reactions
what are the applications of CHO in food
Food companies will want to move with consumer trends with 2 main options…
what are some examples of CHO reformulation
what did the SCAN report for carbs and health say
what is the definition of vitamins
what are the main functions of vitamins
what vitamins cannot be synthesised in the body
what vitamins are fat soluble
what vitamins are water soluble
how is the amount of vitamins in food reduced
what are some specific examples for vitamins being lost from food
what 2 stages does the breakdown of amino acids occur
what % DHA is vitamin C activity
what % DKG is vitamin C activity
how do catalysts increase vitamin C loss
how do inhibitors decrease vitamin C loss
what is the equation for AA–>DHA–>DKG
Where Is vitamin D3 found
what Is the equation for vitamin D3 degradation
when is the maximum synthesis of 500 ug of vitamin D
why does excessive exposure to vitamin D not cause toxicity
why do people manipulate vitamins
what is the purpose of restoration
what is the purpose of fortification
what is the purpose of enrichment
what is Biofortification
what are minerals, what are examples o minerals and how much is needed a day
what are trace elements, what are examples, and how much is needed a day
what are poly(phenolic) compounds
