The objectives of this study were to characterize the quality of soy kefir made with soymilk in combination with fructose (5%, 10%) and one of the extracts from orange (10%, 15%) and grape (5%, 10%) with differently adjusted amounts as defendant variables. The lactic acid bacteria, yeast and total microbial counts of soy kefir were respectively $1.3{\times}10^7$ CFU/ml, $1.6{\times}10^8$ CFU/ml, $1.5{\times}10^8$ CFU/ml, soy kefir was propered to drink. pH of soy kefir mixed by orange and grape extracts was decreased significantly according to add fructose 5%. Acidity became significantly high when orange and grape extracts were added, which means acidity showed similar tendency in the opposite direction. The saccharinity of soy kefir was not significantly in orange extract, but soy kefir added fructose 10% was high more than fructose 5% in grape extract. In sensory evaluation, soy kefirs added orange extract 15%, fructose 5% and grape extract 10%, fructose 5% were estimated highly on color, astrigent taste, sour taste, mouth feel and overall quality.

The study aimed to evaluate the effect of kefir combination from goat milk and soy milk on lipid profile, plasma glucose, glutathione peroxidase (GPx) activity and the improvement of pancreatic β-cell in diabetic rats. Male rats were divided into five treatments: normal control, diabetic control, goat milk kefir, combination of goat milk-soy milk kefir and soy milk kefir. All rats were induced by streptooztocin-nicotinamide (STZ-NA), except for normal control. After 35 d experiment, the rats were sampled for blood, sacrificed and sampled for pancreatic tissues. Results showed that diabetic rats fed kefir combination had higher (p<0.05) triglyceride than the rats fed goat milk or soy milk kefir. Decreasing of plasma glucose in diabetic rats fed kefir combination was higher (p<0.05) than rats fed goat millk kefir. The activity of GPx in diabetic rats fed three kinds of kefir were higher (p<0.01) than untreated diabetic rats. The average number of Langerhans and β-cells in diabetic rats fed kefir combination was the same as the normal control, but it was higher than diabetic control. It was concluded that kefir combination can be used as antidiabetic through maintaining in serum triglyceride, decreasing in plasma glucose, increasing in GPx activity and improving in pancreatic β-cells.

Yeast strains are capable of hydrolyzing non-digestible saccharides, such as melibiose, raffinose, and stachyose, found in soy meal components. This study revealed the biochemical properties of fermented soybean meal during 72 hours with kefir. Starchyose and raffinose, non-digestible components, were almost digested in kefir 150 mL + soybean meal 500 g + water 70 mL and galactose was produced. Proteolysis of the soybean meal produced most of the small molecule peptides in kefir 150 mL + soybean meal 500 g + water 70 mL. The production of the vitamin B group and C were the highest in kefir 250 mL + soybean meal 500 g. The yeast number of the fermented soybean meal was 7.0 × 10⁶ CFU·mL^-1 which was the highest in kefir 250 mL + soybean meal 500 g. The lactic acid bacteria of the fermented soybean meal was the highest at 3.5 × 10⁹ CFU·mL^-1 in kefir 70 mL + soybean meal 500 g. The antioxidant effect was the highest at 57% in kefir 250 mL + soybean meal 500 g. Expression of inflammation-related cytokine (interleukin [IL]-1β, tumor necrosis factor [TNF]-α, and interleukin [IL]-6) was significantly inhibited in fermented soybean meals with different treatments. These results suggest that fermented soybean meal by kefir has an antiinflammatory and anti-oxidation activity and could be utilized in feed manufacturing, and inhydrolyzing non-digestible soy meal components.

Radish (Raphanus sativus L.) has long been recognized as a source of nutrients and phytochemicals. It is well known that the antioxidant properties of radish contributed to its popularity in pharmaceuticals. For this reason, the radish extract aided in the recovery and prevention from diseases. Hence, in this study, the sensory evaluation assessment was conducted following addition of radish oil to almond milk, oat milk, and soy milk (nondairy products) and Kefir, yogurt, and cow milk (dairy products) at different concentrations (containing 0.5% increments from 0% up to 2%). According to the results obtained in this study, all samples containing 0.5% radish oil scored higher on the sensory evaluation scale than the control. It is also very valuable as it is the first study to investigate sensory evaluation assessment by incorporating radish oil into almond milk, oat milk, and soy milk (nondairy products) and kefir, yogurt, and cow milk (dairy products). Furthermore, the results of this study can be used as a foundation for developing future products using radish oil. Additional research on addition of plant-based essential oil to various foods should be conducted.

Broccoli sprouts are an excellent source of health-promoting phytochemicals, such as glucosinolates, phenols, and vitamins. In this investigation, oil extracted from broccoli was adjusted to various concentrations (control, 1%, 2%, 3%, 4%, and 5%, respectively) and added directly to dairy products (cow milk, yoghurt, and kefir) and non-dairy products (soy milk), and their organoleptic properties assessed. The results showed that when the amount of broccoli oil was increased, the organoleptic properties (texture, color, and flavor) and overall acceptability tended to decrease. Cow milk, yoghurt, kefir, and soymilk supple-mented with 1% broccoli oil showed the best organoleptic properties when compared to the control group. The fermented products such as yoghurt and kefir with added broccoli oil showed good organoleptic properties. Overall, the results of this study provide evidence for the use of broccoli oil in dairy and non-dairy products. Further research will be required to assess the various physiological active functions of broccoli oil.
