  Introduction: Acidified milk drinks have low pH with healthy properties. These properties might be expanded and improved by fortification of these products with soy milk, probiotics and Whey Protein Concentrate. The aim of this study is to investigate the impact of transglutaminase (TG) and Whey Protein Concentrate (WPC) on physicochemical, sensory and microbial properties of functional drink from mixture of cow's milk and soya milk. Materials and Methods: Cow's milk and soya milk with equal proportion were used for producing probiotic drink containing Lactobacillus casei. Different concentrations of transglutaminase (150, 200 and 250 ppm) and WPC (0.5, 1 and 1.5 % w/w) were added and the viability of probiotic bacteria and physicochemical and sensory properties of the drink samples were studied during three weeks of cold storage. Results: The results showed that the addition of enzyme and WPC increased the viscosity significantly (p˂0.05). Samples containing 1.5% WPC and 200 ppm enzyme and 1.5% WPC and 250 ppm enzyme had the highest acidity and the lowest pH. The highest number of L. casei belonged to the sample containing 0.5% WPC and 150 ppm enzyme. Moreover, this sample had the highest score of overall acceptability during storage. During the storage time, the viability of L. casei and pH decreased significantly (p˂0.05) whereas acidity and viscosity increased significantly (p˂0.05). The population of probiotic bacteria of the samples during storage was more than 106 CFU/ml. Conclusion: The addition of 0.5% WPC and 150 ppm transglutaminase resulted in production of a functional drink with the highest viability of probiotic bacteria and sensory quality. Manuscript profile

  Cardiovascular disease is related with various risk factors. The most important of these are age. Coronary arterial disease mortality is increased after menopause. It is due to hypoestrogenemia. Soy bean is a source of fetoestrogen that is similar to hormone. The most important fetoestrogen is isoflavone. Soy bean is source of isoflavone that can decrease serum total cholesterol so protect of heart disease.In this randomized clinical trial 50 menopause women with hyper lipidemia and inclusion criteria were chosen. They were divided randomly to two groups (control and soya milk) diet. In soya milk group they were given 1 liter soya milk every day for 12 weeks. In control group they were not given soya milk or any product of soya. Initial and after 12weeks they were assayed for serum lipids profile. Data were collected and analyzed by SPSS software. There were no significant changes in serum lipids profile (triglyceride, HDL-cholesterol, LDL-cholesterol, total cholesterol) within control group Initial and after 12 weeks (P=NS). There were no significant changes in serum lipids profile) triglyceride, HDL-cholesterol, LDL-cholesterol, total cholesterol) within soya milk group Initial and after 12 weeks (P=NS). There were no significant changes in serum lipids profile) triglyceride, HDL-cholesterol, LDL-cholesterol, total cholesterol)between soya milk group and control group Initial and after 12weeks (P=NS).It seems soy milk has no actually effects on serum lipids profile, therefore this subject need to additional studies.
