Assessment of fermented buffalo milk for Lactobacillus casei and supply with Bifidobacterium longum

Abstract

It was elaborated fermented buffalo milk for L. casei utilizing skimmed milk added with 12,00% sugar and fermented by 24 hours. After fermentation, the product was supply with B. longum and storage during 30 days at 5 and 10° C, being evaluated the acidity, pH and viability of L. casei and B. longum parameters. Were does the nutritional composition, calculate the caloric value and sensorial analysis of the flavored product. The fermented milk presented initial acidity 0.69% and pH 4.86. The L. casei initial viability was 11,00 log CFU/mL and B. longum 10,46 log CFU/mL. After storage of 30 days, the acidity and pH were adequate and the L. casei and B. longum viability was above 9.00 log CFU/mL. The composition analysis resulted (%) protein 3.63, carbohydrate 21.86, fat 0.10, ashes 0.56, wet 73.85 and dry substance 26.15, with caloric value 103 Kcal/100 g. There wasn't significant difference to preference and acceptance between flavored samples, and have good acceptation by hedonic scale.
