when there is equal amounts of glucose and fructose

what is the difference between intrinsic and extrinsic sugars
ntrinsic sugars are sugars that occur naturally in the cellular structure of food while extrinsic sugars are added or are free in food. Intrinsic sugars are mostly found in fruits and vegetables. Extrinsic sugars are found in honey

name all the reducing sugars
Maltose, Lactose, Glucose, Fructose
3 of 13
what effect do reducing sugars have on the fehling solution
it turns blue solution to a brick red colour due to the production of copper 1 oxide

what is the structural difference between amylose and amlopectin
amylose: un branches, made up of 200 - 500 cellulose fibres, 1,4 gylosic links. amylopectin: branched, up to 10, 000 cellulose fibers and has 1,4 and 1,6 gylcosidic links

what is Gelatinisation of Starch
the ability to form a gel which is able to thicken a large number is foods

what is NSP
non-starch polysaccharide.

give an exapmle of an nsp
fibre
8 of 13
what is the role of fibre
The main function of fibre is to keep the digestive system healthy and functioning properly. Fibre aids and speeds up the excretion of waste and toxin
9 of 13
how can carbohydrates affect our health
carbohydrates provide energy
10 of 13
what is the importance of hydrogen bonding in gelatinisation
hydrogen bonds allows a gel network to from, trapping the ater and forming a gel on cooling.
11 of 13
explain the enzymic breakdown of starch
two enzyme systems work together rapidly to break down starch to maltose and come dextrins.

how does cellulose act as a stabilizer
The gelling action of cellulose when combined with water provides both thickening and stabilizing qualities in the food. Cellulose gel acts similarly to an emulsion, suspending ingredients within a solution and preventing water from separating out
