Analysis Of Organic Acids And Functional Studies In Microecological Preparations

In this study,chromatographic method,kit method and animal experiment were used to study the organic acid composition,passaging stability,antioxidant properties and weight loss and blood fat reduction characteristics of microecological preparations.The main research results were obtained:1.Fermentation with microecological preparations,the products of which are mainly organic acids.Among them,the lactic acid content is the most abundant,followed by acetic acid.There is also a certain amount of malic acid,succinic acid and a small amount of tartaric acid,formic acid and oxalic acid.The main organic acid species and composition ratio in the fermentation broth samples were consistent.Although the content of main organic acids varies with the increase of microbial passage number,it only fluctuates within a small range.To some extent,the organic acid composition can be considered to be relatively constant.From the results of the study,it can be considered that different organic acids remain relatively stable in the system when the microorganisms are used to ferment the wine.2.The total antioxidant capacity of the microecological preparation is close to that of the orange juice beverage,which is higher than that of the peach branch beverage,which is much higher than the persimmon vinegar drink and the apple cider vinegar drink.It is indicated that the microecological preparations have relatively strong antioxidant power.As the amount of addition increases,the ability to scavenge DPPH free radicals increases.The microecological preparations and the orange juice have the same ability to remove,and both show better removal effects.3.The weight change of the mice in the weight loss model group showed that the microecological preparation can significantly inhibit the growth of the body weight of the mice;by measuring the fat weight and fat coefficient of the mice,it can be known that the foods with higher fat content are often caused to cause obesity,and the microecological preparations can be obviously Inhibit excess growth of fat.By measuring the content of triglyceride and total cholesterol in the serum of mice in the weight loss model group,the serum triglyceride and total cholesterol in the mice of the microecological test group were significantly lower than those in the obese group and the control group.Effectively inhibits the growth of total cholesterol and triglycerides in the serum of mice.By measuring the serum triglyceride and total cholesterol levels in the hyperlipidemic model group,the microecological preparation can effectively inhibit the increase of total cholesterol and arteriosclerosis index in the serum of mice,but to triglycerides and high density lipoprotein.Cholesterol has a certain effect.
