内蒙古西部地区自然发酵酸粥化学成分及微生物组成分析

Analysis of chemical and microbiological composition in naturally fermented acidic-gruel from western areas of Inner Mongolia

对采集自内蒙古西部地区28份自然发酵酸粥样品进行了化学成分和微生物组成分析。其酸粥样品化学成分和微生物组成分析结果为:总固形物1.43±0.45g/100g、蛋白质0.57±0.18g/100g、脂肪23.11±10.06mg/100g、乳酸0.282±0.093g/100g、乙酸0.065±0.046g/100g、γ-氨基丁酸0.034±0.022g/100g、游离氨基氮0.366±0.116g/100g、灰分0.20±0.08g/100g、钙14.59±1.59mg/100g、磷11.19±5.54mg/100g、酸度51.12±21.87°T、黏度5.15±0.89mPa·s、细菌总数7.67±1.23lgcfu/mL、乳酸菌数7.51±1.23lg cfu/mL和酵母菌数5.55±0.68lg cfu/mL。结果表明,内蒙古西部地区自然发酵酸粥具有丰富的营养成分和较高的乳酸菌数,是一种对人体健康有益的发酵谷物食品。

The chemical composition and microorganism flora of the 28 samples of naturally fermented acidic-gruel from four different western areas of Inner Mongolia were analyzed. The major chemical composition of acidic-gruel samples were as follows： total solids 1.43±0.45 g/100 g, protein 0.57±0.18 g/100 g, fat 23.11±10.06 mg/100 g, lactic acid 0.282±0.093 g/100 g, acetic acid 0.065±0.046 g/100 g, γ-aminobutyric acid 0.034±0.022 g/100 g, free amino nitrogen 0.366±0.116 g/100 g, ash 0.20±0.08 g/100 g, calcium 14.59±1.59 mg/100 g, phosphorus 11.19±5.54 mg/100 g, titratable acidity 51.12±21.87 o T, viscosity 5.15±0.89 mPa·s, total bacteria counts 7.67±1.23 lg cfu/mL, lactic acid bacteria counts 7.51±1.23 lg cfu/mL and yeast counts 5.55±0.68 lg cfu/mL. The result was that acidic-gruel which contained a great nutritional ingredients and high lactic acid bacteria counts is a kind of beneficial fermented beverage to human health.
