Chemical and microbiological properties of buffalo milk kefir with different starter concentrations

Abstract

The research aims to determine the effect of kefir grain starter concentration on alcohol content, total dissolved solids and total buffalo milk kefir microbes and to find out whether these parameters are in accordance with predetermined standards. The study used a Completely Randomized Design (CRD) with treatments given were (T1) kefir grain starter concentration of 2.5%, (T2) 5% kefir grain starter concentration, (T3) kefir grain starter concentration of 7.5%, and (T4) concentration 10% kefir grain starter. The parameters observed were alcohol content, total dissolved solids and total microbes. Data from the test results were analyzed using the Analysis of Variance (ANOVA) test with a significance level of 5% and if there is a difference then proceed with the Duncan test. Kefir grain starter concentration has a significant effect (p<0,05) on alcohol content, total dissolved solids and total microbes. The more concentrations of kefir grain, the alcohol content and total microbes increase. The more concentration of kefir grain, the more total dissolved solids decreases, with the optimal amount of kefir grain starter concentration is 7.5%.

Physicochemical and Sensory Quality of Probiotic Drink from Sumbawa Wild Horse Milk

“…Total dissolved solids differed significantly and generally decreased. Consistent with the findings of Rizqiati et al, (2021), the total dissolved solids content of buffalo milk kefir ranges from 4.00 to 4.94°Bx and decreases as the concentration of kefir starter increases. It's possible that the change happened because lactose broke down into galactose and glucose, which then turned into lactic acid.…”

“…In general, the total dissolved solids is a measurement utilized to determine the quantity of materials that have dissolved in a solution. When it comes to lactose, total dissolved solids can be used to figure out how much sugar is in a substance (Rizqiati et al, 2021). The Sumbawa wild horse milk probiotic drinks contain between 11.95±0.14°Bx and 13.10±0.07°Bx of total dissolved solids.…”

Biodiversity of Indonesian indigenous buffalo: First review of the status, challenges, and development opportunities

“…Several studies have been conducted to investigate the probiotic activity of lactic acid bacteria in buffalo milk in West Sumatra province [ 53 ] and North Sumatra [ 54 ] using buffalo milk of dairy buffalo breeds, as well as the milk of the Tedong Bonga breed in South Sulawesi [ 55 ]. These investigations are of interest because researchers are trying to determine the potential of buffalo milk of different breeds in various provinces.…”
