Abstract

The objective of this research was to investigate the chemical, physical and sensory properties of goat milk kefir  during storage under different temperatures and storage time. Experimental method, applied completely randomized factorial design. The first factor was temperature (-1 to -5oC; 5 to 10oC and 6 to 10oC) and the second factor was storage time (10; 20 and 30 days) followed by Duncan test. Result showed that temperature, storage time and interaction highly significantly affected (P<0.01) the level of ethanol and FFA, but not affected (P>0.05) on protein content, fat and ash but CO2 level, texture and flavor of kefir were affected by storage time. Kefir viscosity was only affected by storage temperature (P<0.05). Research concluded that storage temperature affected chemical properties such as ethanol, FFA and kefir viscosity,while kefir sensory properties was predominantly affected by storage

Abstract

This research set out to compare the physical and microstructural characteristics of kefir made of milk, colostrum, and milk-colostrum mixes at various proportions. Kefir was made by adding kefir grains to 100% milk (P0), 80% milk + 20% colostrum (P1), 60% milk + 40% colostrum (P3), 40% milk + 60% colostrum (P4), 80% milk + 20% colostrum (P5), and 100% colostrum (P6). Fermentation was allowed under room temperature for 24 hours. The characteristics observed were color values, viscosity, pH, water holding capacity (WHC), syneresis, and microstructure. The result showed that the color of kefir (L* value, lightness); (b* value, yellow-blue), (a*, red-green), and whiteness index (WI) was significantly affected by raw materials. The viscosity of kefir was also affected by the raw materials (p<0.05), in which the kefir made from a mix of 80% milk and 20% colostrum showed the highest viscosity (1524.20 m.Pa.S). However, other characteristics such as pH, WHC, and syneresis were not significantly affected by raw materials. The microstructure of kefir made from 20 to 40% colostrum showed a string and compact protein tissues, while that made from 80 to 100% colostrum showed a clumping gel and concentration dominated by protein and fat tissues.  This study demonstrated that milk kefir produced from milk-colostrum mixes posses a yellowish color (b*), low whitenes index, negative a* value, low lightness, whereas kefir made from 100% colostrum showed slightly greenish with low lightness level. Kefir with highest viscosity was produced from combined 80% milk and 20% colostrum. The microstructure of kefir produced from mixes with 40% and 60% colostrum showed a strong, tight, and compact microstructure of protein tissues.

Abstract

This study aimed to evaluate the properties of low-fat cottage cheese with the addition of herbs. We conducted an experiment with nine treatments, namely P1: whole-milk cottage cheese; P2: low-fat cottage cheese; P3: low-fat cottage cheese + 20% bidara leaf extract; P4: low-fat cottage cheese + 20% bay leaf extract; P5: low-fat cottage cheese + 20% moringa oleifera leaf extract; P6: Low-fat cottage cheese + 10% bidara leaf extract + 10% bay leaf extract; P7: low-fat cottage cheese + 10% bidara leaf extract + 10% moringa oleifera leaf extract; P8: low-fat cottage cheese + 10% bay leaf extract + 10% moringa oleifera leaf extract; and P9: low-fat cottage cheese + 6.67% bidara leaf extract + 6.67% bay leaf extract + 6.67% moringa oleifera leaf extract. The microbial profile of cheese showed that the total LAB count was retained at 6.23-7.25 log CFU/g. While herb-fortified cottage cheese contained a significantly higher level of antioxidants, the lowest cholesterol level was observed in cottage cheese fortified with 20% bidara leaf extract. The general fatty acids in cheese without herb addition were saturated fatty acids (51.94%) and unsaturated fatty acids (15.67%), with palmitic acid being the most predominant fatty acid (36.62%). In conclusion, herbs can improve antioxidant levels and retain total fatty acid in low-fat cottage cheese.
