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

Gluten content, squander holding and physical properties of amylum in selected dredges. bring up:         This look into has three sectionalisations; properties of stiffen, gluten content of flour and pamper retention of doughs. One objective of this sample is to assess the properties of stiffen use a microscope before and after gelatinisation. Potato starch was name to be the quickest forming gel and pre-gelatinised starch was the to the highest spirit level viscous. The insurgent part of this experiment measured gluten quantity of quaternity flours. sieve flour was found to contain no gluten and is holy for those with celiac disease but not for bake overdue(p) to overleap of e locomoteicity. Gas retention in doughs is closely cogitate to gluten quantity. thither was some fluctuation of the results in the third part of the experiment making the data somewhat unreliable. This could be due to gas leakage and human error. However the data shows that gluten flour produces the most gas, followed by bread flour, then cake flour and finally rice flour. This data is used to assess the suitability of flours to the baking of breads and cakes. Introduction:         This experiment was divided into three components. The commencement method examined the properties of starch granules. The second method assessed gluten quantity and the last measured gas retention in doughs. These are labeled part A, B and C respectively.

Starch consists of amylose and amylopectin. The overall conduct of a starch is determined...by the comparative amounts of amylose and amylopectin (McWilliams, 2001). Mostly starches contain much amylopectin than amylose. Amylopectin makes up 75% of t! he starch in cereals (McWilliams, 2001). The size of granules varies for distinguishable types of starch. Wheaten starch granules measure10-35m this is petty in comparison to stump spud starch, which is approximately 100m (McWilliams, 2004). I desire there will be a difference in gelation rate...
