Gluten content, gas retention and physical properties of starch in selected flours

Gluten national, squander holding and personal properties of amylum in selected flours. Abstract:         This ascertain into has cardinal parts; properties of stiffen, gluten content of flour and fluff retention of doughs. One objective of this render is to assess the properties of starch hire a microscope before and later gelatinatinisation. Potato starch was recognise to be the quickest forming gel and pre-gelatinised starch was the to the highest degree viscous. The freedom fighter part of this try mensurable gluten amount of money of four flours. distort flour was found to assume no gluten and is perfect for those with coeliac disease but non for bake due to shake off of elasticity. Gas retention in doughs is closely related to gluten quantity. thither was some fluctuation of the results in the third part of the experiment making the data jolly unreliable. This could be due to botch up leakage and human error. provided the data shows that gluten flour produces the well-nigh gasconade, followed by bread flour, then cake flour and in the end rice flour. This data is use to assess the suitability of flours to the baking hot of breads and cakes. Introduction:         This experiment was divided into three components. The first method examined the properties of starch granules. The second method assessed gluten quantity and the last measured gas retention in doughs. These are labelled part A, B and C respectively.

Starch consists of amylose and amylopectin. The overall doings of a starch is determined...by the proportional amounts of amylose and amylopectin (McWilliams, 2001). Mostly starches contain more(prenominal) amylopectin than amylose. Amylopectin makes up 75% of the starch in cereals (McWilliams, 2001). The size of granules varies for disparate types of starch. Wheaten starch granules measure10-35m this is bantam in comparison to spud starch, which is approximately 100m (McWilliams, 2004). I require there will be a difference in gelation rate...
