Effects of Cholesterol Extraction Process and Fat and Whey Protein Additions on Ice Cream Mixes.

The aim of this work was to evaluate the cholesterol extraction process in ice cream mixes (ICMs) by using β-cyclodextrin (βCD) and to analyze the effect of this extraction on the ICM rheological, stability, and sensory characteristics. The effects of fat and whey protein (WP) additions on ICM stability were also evaluated. The maximum percentage obtained for cholesterol extraction was 93.

A study on bovine kappa-casein aggregation after the enzymatic action of chymosin.

Kappa-casein (kappa-CN) is a milk phospho-glycoprotein that plays an important role in the electrostatic and steric stabilization of casein micelles suspensions. kappa-CN characteristics such as its aminoacidic composition and its high denaturalization temperature make this protein an excellent nutrient. The enzymatic destabilization of kappa-CN is the basis of cheese and yoghurt manufacture.
