چکیده

I. It was shown that when polyethylene glycol (PEG) was added to suspensions of food particles in aqueous buffer solutions, its distribution in the total water of the food mass was not uniform. The marker was excluded from a large proportion of the water contained in the swollen food particles. This effect was independent of temperature, pH, and, within limits, the time of contact. 2. It was shown that the theoretical concentration (C',,), assuming a uniform distribution of marker, could be calculated from the observed concentration (C) , weight of food in suspension ( W ) and the total volume of water (V) , using the equation C = C,(I + b[W/V]) where b is constant for any given food. The addition of PEG solution to dry food particles gave a smaller effect. 3. The distribution of PEG was usually, but not invariably, more uniform in a suspension of roughages than in a suspension of concentrates. 4. Possible implications of these findings with respect to marker experiments with PEG are discussed.

Cellulase Production by Trichoderma reesei using Sugar Beet Pulp

Cellulase production by the fungus Trichoderma reesei was studied using sugar beet pulp (SBP) as a substrate. The subculture medium was a salt solution consisting of KH2PO4, CaCl2, etc. Fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°C for 1-2 generations (two days for each generation) and were then used as an inoculum. Exponential cells were inoculated into a medium contain...

استخراج پکتین از تفاله چغندر قند وبررسی کاربرد آن در محصولات غذایی

Pectin is used in a number of foods as a gelling agent, thickener, texturizer, emulsifier and stabilizer. Sugar-beet pulp, the residue left from sugar extraction, is a rich source of pectin. It was the purpose of this study to develop a procedure for the extraction of pectin from sugar-beet pulp and to improve the functional properties of this pectin for more potential uses. To extract pectin, ...
