To develop a health-aid preparation of Chinese yam (Dioscorea batatas Decne), lactic acid fermentation was attempted using a mixed starter comprising of Lactobacillus acidophilus, Streptococcus thermophilus, and Bifidobacterium bifidus. The anaerobic fermentation of a 5% Chinese yam flour suspension gave a uniform suspension of pH 4.35, containing $7.76{\times}10^6 CFU/mL$ lactic acid bacteria (LAB), and which was found to be acceptable to the panel from a sensory assessment. During the administration of the lactic acid fermented (LAF) Chinese yam to Sprague Dawley rats for 6 weeks, a smaller body weight gain, but greater excretion of feces were observed, implying the creation of a healthy gastrointestine on the administration of LAF Chinese yam, which was also confirmed by the gastrointestinal motility of the feed in rats fed on LAF Chinese yam. The constipation induced by loperamide was further suppressed in a rat group fed on a LAF Chinese yam diet, which was qualified from healthy gastrointestinal flora established by LAB. A serochemical analysis revealed a slight improvement in the blood glucose, neutral lipid and total cholesterol concentrations on administration of LAF Chinese yam, suggesting LAF Chinese yam could be served as a healthy-aid preparation, even for hyperglycemia or hyperlipidemia patients.

제안 방법
However, until now, LAF natural herbs have not been reported. In this study, LAF Chinese yam (D. batatas Decne) was prepared, and its pharmacological effect on gastroin testinal function evaluated for the development of a health-aid preparation.
대상 데이터
Specific pathogen-free male Sprague Dawley rats (4~5 weeks old) were purchased from Samtako, Inc. (Osan, Korea). Three animals were housed per cage and fed a rat chow diet (Netsle Purina PetCare Korea, Ltd.
The LAF suspension of Chinese yam flour was evalu ated by 25 well-trained panelists. The panel reported that the LAF Chinese yam suspension were relatively sour, with low sweetness, but acceptable for taking as a 5% suspension of fermented Chinese yam flour (Table 1).
이론/모형
and total cholesterol. The glucose concentration was determined by the glucose oxidase method, using an YSI Glucose Analyzer (YSI 1500, USA). The serum neutral lipids and total cholesterol concentrations were measured using a kit obtained from the Sigma Chemical Co.
The sensory tastes of LAF Chinese yam were evaluated according to the 5-point scores method [21] by a welltrained panel of 25 persons.
