Effect of the Difference in the High Molecular Weight Fraction of Whey Between Cow`s Milk and Goat`s Milk on Creaming Phenomenon

The rapid formation of a cream line cannot be observed in raw goat''''''''''''''''s milk standing at a low temperature. Although the poor creaming ability of goat''''''''''''''''s milk has been considered to be due to the small size of milk fat globules and the lack of euglobulin capable of being adsorbed on milk fat globules, there is much left to study. The present work attempted to elucidate a factor for poor creaming ability of goat''''''''''''''''s milk. The creaming ability of the experimental milks reconstituted from creams and skim milks separated from cow''''''''''''''''s milk or goat''''''''''''''''s milk was measured by the volume of the cream layer and the fat content of bottom layer. The polypeptides composition of the P1 the fraction (i.e., the high molecular weight fraction eluted near the void volume obtained by the gel filtration of whey) and milk fat globule membrane prepared from both milks were compared. It was found that the promotion of creaming originated from goat''''''''''''''''s skim milk was lower than that from cow''''''''''''''''s skim milk. The P1 fraction in goat''''''''''''''''s skim milk was less than that in cow''''''''''''''''s skim milk. The polypeptide (M.W. 4.3횞104), found in the P1 fraction of cow''''''''''''''''s milk was not found in the P1 fraction of goat''''''''''''''''s milk. It is suggested that the poor creaming ability of goat milk is caused mainly by the difference from cow milk in the amount and the composition of the P1 fraction.
