Creamed Cottage cheese enriched with Lactobacillus GG
Cottage cheese was produced from reconstituted skimmed milk powder Fer mentation of skim milk with approximately 11.16% total solids was performed at 22 °C with 0,5% mesophilic starter culture, "O" type (DVS, Chr Hansen's Lab), without rennet addition. Dry Cottage cheese samples contained an average 21,32% total solids; 17.85%) proteins; 0.75%) ash; and 90.33 mg Ca/lOOg. The Cottage cheese pro...
متن کاملPretreatment of Cottage Cheese to Enhance Biogas Production
This study evaluated the possibility of pretreating selected solid fraction of an anaerobic digester treating food waste to lower the hydraulic retention time and increase the methane production. The study investigated the effect of different pretreatments (thermal, chemical, thermochemical and enzymatic) for enhanced methane production from cottage cheese. The most effective pretreatments were...
متن کاملSulfhydryl Groups in Proteins
Egg albumin in the native, unaltered state, does not give tests characteristic of sulfhydryl groups. When, however, this protein is treated in any one of several ways, such as by heat (8, 9, 17), ultraviolet irradiation (lo), shaking (lo), or by solution in urea or other amides (7), free sulfhydryl groups make their appearance. The amount of free -SH groups appearing in egg albumin through the ...
متن کاملSulfhydryl Groups in Films of Egg Albumin
1. The same number of SH groups reduces ferricyanide in surface films of egg albumin as in albumin denatured by urea, guanidine hydrochloride, Duponol, or heat, provided the ferricyanide reacts with films while they still are at the surface and with the denatured proteins while the denaturing agent (urea, heat, etc.) is present. 2. The SH groups of a suspension of egg albumin made by clumping t...
متن کاملDetermination of moisture in cheese and cheese products.
Variables related to oven-drying samples of cheese and cheese products to determine moisture content were examined to provide more efficient and reproducible methods. Over 6500 samples of cheese were analyzed in an effort to modify the current AOAC procedure. The gravity atmospheric oven was unsuitable for use in accurate moisture analysis because of wide temperature differentials within the ov...
