大豆、胡萝卜复合固体饮料加工工艺及稳定性的研究

【摘要】 以大豆、胡萝卜为主要原料,采用喷雾干燥法加工稳定性良好的固体饮料。喷雾干燥的适宜工艺条件:进料浓度为8%,进料速率为30～35mL/min,进风温度为220～240℃、喷头压力为0.30～0.40MPa,在此工艺条件下,大豆、胡萝卜复合固体饮料的含水量为3.0%～4.9%,胡萝卜素的含量为15.2～17.6mg/100g。添加0.08%的单硬脂酸甘油酯可以防止产品冲溶、静置后胡萝卜素、大豆脂肪上浮出现“油圈”。更多还原

【Abstract】 The solid beverage processed by spay drying with carrot and soybean as raw material was developed. The optimum parameters for spray drying were as follows: feeding rate 30～35mL/min, input air temperature 220～240℃, pressure of spraying head 0.30～0.40MPa, concentration of feeding material 8%, under this processing conditions, the moisture and carotene retention of product were 3.0%～4.9%, 15.2%～17.6mg/100g, respectively. 0.08% glycerin monostearate could inhibit soybean oil and carotene from accumulating and suspending.更多还原
