Abstract

Nutritive compositions were analyzed in 10 batches of samples of Tarag (the traditional naturally-fermented goat milk), which were collected in the Mongolian community in China. Results showed that Tarag had richer nutrients than yoghurt. Tarag-2 (from Zang goats) had better chemical nutrient density than Tarag-1 (from Chaidamu goats). Tarag was rich in casein, lactoferrin, serum albumin, β-lactoglobulin, α-lactalbumin, and 3 unknown fractions in certain samples. Microbiological enumeration revealed that Tarag contained large lactic acid bacteria and yeast. Tarag was judged nutritious and indicated the latent value for people's health.

摘要

对采集于中国蒙古族社区的10批传统自然发酵山羊奶“塔拉额吉”样品中的营养成分进行了分析。结果表明，“塔拉额吉”的营养成分比酸奶更丰富。塔拉额吉-2（来自藏山羊）的化学营养密度比塔拉额吉-1（来自柴达木山羊）更好。“塔拉额吉”富含酪蛋白、乳铁蛋白、血清白蛋白、β-乳球蛋白、α-乳白蛋白，并且在某些样品中含有3种未知成分。微生物计数显示，“塔拉额吉”含有大量乳酸菌和酵母菌。“塔拉额吉”被判定为营养丰富，对人体健康具有潜在价值。
