以绿豆变性淀粉和麦芽糊精作为脂肪代替品代替脂肪生产低脂冰淇淋。以冰淇淋的膨胀率、融化率、开始融化时间和浆料黏度作为考察指标,采用响应面法中的中心组合设计优化低脂冰淇淋的配方。结果表明:当绿豆变性淀粉添加量为1.5%、麦芽糊精添加量为2.0%时,低脂冰淇淋的膨胀率、融化率、开始融化时间和浆料黏度分别为61.7%、20.0%、1 249 s和1 243 mPa·s;按照最优配方制得的低脂冰淇淋的硬度、黏附性、弹性和咀嚼性分别为(811.4±4.4) g、(215.7±2.5) g?s、1.091±0.025和 相似文献

This study was conducted to investigate the quantitative and qualitative changes in dietary and endogenous protein components along the small intestine of calves. They were fed milk replacers in which protein was provided either by skim milk powder alone, as control diet, or by skim milk powder and a soy concentrate, a partially hydrolyzed soy protein isolate, or a potato protein concentrate (1:1 on a CP basis). The calves were continuously infused with the liquid milk substitute diets into the abomasum. Duodenal, jejunal, and ileal digesta were collected through T-piece cannulas. Digestibility (corrected for total endogenous protein) of dietary protein and the concentration of dietary, host endogenous, and bacterial proteins were estimated from the AA composition of digesta using multiple linear regression. The apparent digestibility of feed components increased linearly between the duodenum and the ileum. It was lower with the diets containing plant protein than with the control, especially at the ileum (85% for CP with soy concentrate, 73% with soy isolate, and 81% with potato concentrate vs 91% with skim milk powder). The real digestibility of dietary protein at the ileum was estimated to be 96, 95, 94, and 99%, respectively, for each of the dietary components. The partition of protein components in digesta between dietary, nonspecific endogenous, specific host endogenous, and(or) specific bacterial proteins varied along the small intestine and between diets at a given site. Intestinal apparent reabsorption of host endogenous protein was estimated to be equivalent to at least 86% of the jejunum flow. To conclude, the lower apparent digestibility of the plant protein sources studied resulted more from an enhanced loss of host and bacterial endogenous proteins than from decreased hydrolysis of dietary protein and absorption of their AA. 相似文献

本研究以发酵型益生菌冰淇淋感官指标(细腻度、口融性、发酵味、酸甜比、勺取性与硬度),物理指标(膨胀率、抗融性与黏度)以及发酵剂与益生菌存活率作为指标,对发酵型冰淇淋主要配料中的白砂糖、复合乳化稳定剂的添加量进行了单因素试验,对两种配料的最优添加量进行了优化。结果表明,发酵型益生菌冰淇淋的配料中白砂糖的最优添加量为13%,复合乳化稳定剂的最优添加量为0.3%~0.45%。白砂糖、复合乳化稳定剂的添加量经过了优化,为企业今后生产该类产品提供了一定的理论、技术支持。 相似文献
