the ability of water absorption of
Gluten
:
Gluten can absorb 1.5-2 more than
it̕s weight water . absorption water in
early stage of paste making depends a lot to time and it is because
of 2 reason: 1- for moisture of all gluten̕
s molecules needs to 1 minute time .gluten̕s
parts surrounded by flours parts. paste̕
s water first moisture the parts of flour and influence the parts of
gluten .in this case water as a surface water and link with it.
2- molecules of gluten swell .some part of
water penetrate in amino acids and save there .the feature and
characteristic of gluten in various wheat is different ,in common it
depend on genetic .quality and quantity of gluten depend on the
condition of cultivation ,fertilizer , environment ,etc. there is
relationship among crude protein ,pure protein and the amount of
gluten .according research of WALL the amount of gluten relate with
the quality of it .behavior the glutein is a important factor ,
because the the portion of non soluble proteins in water relates
directly with the bulk of products .the strenght of
paste by adding revival material in tensile of gluten decrease.
glutation of wheat floor act as a revival ( like sistein )and smooth
the paste .can oxide to di-sulphide. by adding certain amount of sorbic acid we can effect the amount of glotation of flour. by
this flour has a more elasticity and very soon made get the
adhesiveness feature.
Application :
gluten is use in food industry , meat
industry such as :hamburger,in flour product s such as : diet bread
, cacke , childs food , spaghetti ,
carton fabrication, glue and adhesive,
biscuit & backer, amender, in product of amino acids, and in
detergent material. |
