速溶减肥咖啡饮料的研制及功能性评定

The Preparation of the Instant Coffee Beverage with Weight-reducing Function and its Functional Evaluation

以丙酮酸钙和l-肉碱为主要原料,以咖啡溶液为载体,通过试验,解决了丙酮酸钙的增溶问题以及减肥咖啡饮料的口感调配,确定饮料的最佳配方(以200mL计)为:丙酮酸钙2.5g、左旋肉碱0.5g、咖啡1.8g、麦芽糊精5g、增溶剂0.66g、黄原胶0.08g、酪蛋白酸钠0.5g、甜味剂(木糖醇6g、甜蜜素0.35g)、消泡剂0.10g、香精0.003mL。另本文还探讨了减肥咖啡饮料对大鼠体重及血清中的TC、TG、HDL-C浓度的影响。将Wistar雄性大鼠随机分为高、中、低三个剂量组和一个对照组,分别对高、中、低三个组以人体推荐剂量的20倍、10倍、5倍进行灌胃。实验结果显示,与对照组相比,低剂量组具有使大鼠体重下降的趋势,且明显降低血清甘油三酯的浓度。动物实验表明本试验研制的速溶减肥咖啡饮料具有一定的减肥作用。

this paper studied the preparation of the instant coffee beverage with weight-reducing function which used Calcium pyruvate and l-carnitine as main materials. In addition, the problems about improving the solubility of calcium pyruvate and the taste of the instant coffee beverage were solved. The best formula of the functional beverage (per 200 mL) were : 0.5g l-carnitine, 2.5g calcium pyruvate, 1.8g coffee, 5g malt dextrin, 0.66g Solubilizer, 0.08g xanthan gum, 0.5g sodium caseinate, 6g xylitol, 0.35g cycl...
