Significant Difference

Twenty five market skim milk powder samples obtained from various regions of Maharashtra were analysed for their chemical composition, physico-chemical properties and microbiological quality to access their suitability in terms of national and international standards. It was observed that the moisture, fat, protein, lactose and ash content of SMP samples obtained from various regions showed significant difference (P less than 0.05). It was also revealed that the scorched particle content, solubility index, dispersibility, wettability properties of samples varied significantly in different regions for different brands. Similarly, the NPN and true protein content in SMP samples of different regions were significantly different from each other. The average free fat content in the samples from Vidarabha was significantly higher than that of the other regions of the state. The titratable acidity and lactate content of various brands of SMP samples were ranged from 0.97-1.08 and 75-550 mg/100 g, respectively. It was observed that three brands out of twenty five samples were found positive for alkali neutralizers. Wide variation was observed in standard plate count and coliform counts of all the SMP samples of various brands collected from five different regions of Maharashtra.

Water Holding

The effect of different concentration of transglutaminase - TG (0.02%, 0.06% and 0.12%) on physico-chemical properties of probiotic yoghurt was investigated. Two series of yoghurt were manufactured on a laboratory scale from pasteurised skim milk (0.1 % w/w fat). Series I was produced with TGase activation during a period of 2 h at 40?C, while series II was produced without enzyme activation. Then, the adequate quantities of TGase and probiotic starter culture ABT-4 (Chr. Hansen A/S Denmark) were added. Chemical composition, physico-chemical properties (water holding capacity and whey separation) and sensory characteristics of yoghurt samples were determined after production and during 5 days of storage. Addition of TGase to milk (direct or after activation) for probiotic yoghurt manufacture improved its overall characteristics. Activation of TG in yoghurt production increases water holding capacity as well as decreases syneresis during the storage.

Fracturing under ultrahigh vacuum (UHV, p ≤ 10-9 Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite foe studies of interactions between condensing molecules is possible and surface forces are unequally distributed, the condensate will accumulate at places with high binding forces; crystallites will arise which may be useful a probes for surface sites with specific physico-chemical properties. Specific “decoration” with crystallites can be achieved nby exposing membrane fracture faces to water vopour. A device was developed which enables the production of pure water vapour and the controlled variation of its partial pressure in an UHV freeze-fracture apparatus (Fig.1a). Under vaccum (≤ 10-3 Torr), small container filled with copper-sulfate-pentahydrate is heated with a heating coil, with the temperature controlled by means of a thermocouple. The water of hydration thereby released enters a storage vessel.
