液体奶加工的原料(即原牛奶)含有大量的水分,而牛奶中的所谓干物质,包括蛋白质、乳脂、乳糖、维生素、盐类等其总质量分数只占约11.0%~14.0%。原奶中的干物质的质量分数随区域、奶牛品种、季节、饲料等因素可能有较大的变化。中国地区一般品种原牛奶干物质质量分数相对较低,一般质量分数在11.0%~12.5%。虽然国家标准中对于液体奶产品干物质质量分数的要求较低,但对于乳品生产企业来讲,为保证产品质量的一致性,提升产品的档次,有必要适当提高牛奶干物质质量分数,将其标准化在一个适当的水平上,这个标准化的… 相似文献

An attempt has been made to prepare seven weaning foods and two high-protein biscuits based on sesame protein. The evaluation of their chemical composition, amino acids, physical and sensory properties showed the successfull use of sesame flour in combination with dry skim milk and either corn or rice starch in preparing these types of food. 相似文献

以白芝麻为原料,无需过滤工艺,采用高压射流磨系统制浆,以表观稳定性和粒径为评价指标,确定了最适压力,以不稳定指数、表观稳定性和粒径为评价指标,研究了复合稳定剂(黄原胶、蔗糖酯和单甘酯)添加量,对适宜工艺下制备的全组分芝麻乳进行超高温瞬时杀菌和无菌灌装,并对最终产品的贮藏稳定性进行了探究。通过表观稳定性和粒径结果,发现随着高压射流磨处理压力的增大,样品稳定性逐渐提高,粒径逐渐减小。当处理压力为120 MPa时,样品稳定性最好,平均粒径D[4,3]最小为68.17 μm。通过不稳定指数、表观稳定性和粒径结果,确定复合稳定剂的最优添加量:黄原胶0.09%,复合乳化剂(蔗糖酯:单甘酯=8:2)0.13%。以此工艺配方生产的全组分芝麻乳在4 ℃贮藏70 d内无沉淀分层现象,不稳定指数无显著变化,且菌落总数符合农业部其他植物蛋白饮料标准。经保质期计算全组分芝麻乳产品在冷藏(4 ℃)和常温(25 ℃)条件下贮藏的保质期分别为5个月和2个月。综上,该工艺可制备一款无需过滤,产品稳定性良好的全组分芝麻乳饮品。 相似文献

Production of sesame milk is one of the methods for increasing consumption of sesame as an excellent nutritional resource. The aim of this study was to examine the effects of sodium bicarbonate concentration in soaking water (0, 0.5 and 1 g/100 mL NaHCO3), roasting temperature (0 and 145 °C) and blanching time (0, 15 and 30 min) on physicochemical and sensory properties of sesame milk. Changes promoted by these processing conditions were also evaluated via color analysis and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The processing parameters mainly affected pH, total solids, protein, fat, ash, lipoxygenase activity, stability, specific gravity, viscosity, color features and sensory properties. Sensory evaluation revealed that overall acceptability was higher in all treatments than the control. SDS-PAGE analysis showed that 7S globulins decreased by roasting and soaking while 11S globulins of sesame milk proteins increased by roasting. The optimum processing conditions were found to be soaking in water containing 0.5 g/100 mL NaHCO3, blanching for 15 min and without any roasting when desirability function method was applied. 相似文献

A technique was developed to protect lactic acid bacteria (Lactobacillus delbrueckii ssp. bulgaricus) against simulated gastrointestinal conditions by encapsulation of bacterial cells within artificial sesame oil emulsions. Purified sesame oil bodies consisting of approximately 99% oil, 0.5% phospholipid, and 0.5% protein were decomposed by heating at 70 degrees C for 1 h. The bacteria cultured in nonfat milk were encapsulated in artificial oil emulsions constituted with decomposed sesame oil bodies and excess sesame or vegetable cooking oil. Viability of bacteria in storage at 4 degrees C for 16 d was substantially elevated from 0.023 to 5.45% after encapsulation. Compared with free cells, the entrapped bacteria demonstrated a significant increase (approximately 10(4) times) in survival rate when subjected to simulated high acid gastric or bile salt conditions. The results indicate that artificial sesame oil emulsion may serve as an effective biocapsule for encapsulation of bacteria in dairy products. 相似文献

The aim of this study was to determine the effect of fat level and composition on chemical, textural, microbial and sensory properties of set yoghurt analogue. The best fat level for production of yoghurt analogue was found to be 2% (w/v). Studies on the effect of fat composition (canola‐to‐sesame oil ratios of 2.0/0, 1.3/0.7, 0.7/1.3, 2.0/0) indicated the superior performance of pure sesame oil. Increasing the canola‐to‐sesame oil ratio generally resulted in an inferior product. Replacement of milk fat by vegetable oils yielded yoghurts with a lower saturated fatty acid content and less firmness. 相似文献
