THE INFLUENCE OF ADDITIONAL ENZYMES TREATMENT OF CORN AND WHEAT STRCHES ON FILTRATION PROPERTIES OF HYDROLYSATES
Lucyna Słomińska, Danuta Wi¶niewska, Joanna Niedbach
ABSTRACT
The influence of additional enzymes: lysophospholipase, beta glucanase and pentosanase on corn and wheat starch were studied. Research was carried out with different starch concentration, enzyme dosages and time of enzyme action. The following analyses were made: dextrose equivalent, the iodine absorbance value, and colour measurement, viscosity and filtration rate. Simultaneous action of alpha amylase and lysophospholipase on corn starch influence on the increase of filtration rate of hydrolysates by 12% and on the decrease of their viscosity, colour indicator and iodine absorbance. Beta glucanase and pentosanase complex used together with lysophospholipase independently on way their introduction to starch increase 2.5 times of the filtration rate of wheat hydrolysates.
Key words: wheat starch, corn starch, lysophospholipase, beta glucanase, pentosanase, filtration..
