Milk Gelation

The aim of the present work was to investigate the role of whey protein denaturation on the acid induced gelation of casein. This was studied by determining the effect of whey protein denaturation both in the presence and absence of casein micelles. The study showed that milk gelation kinetics and gel properties are greatly influenced by the heat treatment sequence. When the whey proteins are denatured separately and subsequently added to casein micelles, acid-induced gelation occurs more rapidly and leads to gels with a more particulated microstructure than gels made from co-heated systems. The gels resulting from heat-treatment of a mixture of pre-denatured whey protein with casein micelles are heterogeneous in nature due to particulates formed from casein micelles which are complexed with denatured whey proteins and also from separate whey protein aggregates. Whey proteins thus offer an opportunity not only to control casein gelation but also to control the level of syneresis, which can occur.

This paper studied the preparation of TiO2 whisker with melt phase-splitting method, which used tataniferous blast-furnance as the main raw materrial. XRD and SEM were used to research the phase and morphology of the sample, and by the same time, the photocatalytic properties of TiO2 crystal-beards was tested.The result have shown:the size of TiO2 crystal-beards was sub-micron rank, the crystal type wasβ-TiO2 of orthorhombic high-pressure phase. The generation of TiO2 crystal-beards were effected mainly by the content of Na2O and TiO2, and the heat treatment temperature. The sample had certain photocatalytic properties and the highest photocatalytic efficiency was 56%.
