辛烯基琥珀酸马铃薯淀粉酯在冰淇淋中的应用研究 总被引:1,自引:0,他引:1
将辛烯基琥珀酸马铃薯淀粉酯作为脂肪替代品代替配方中的奶油,进行了冰淇淋的制备试验。结果表明,冰淇淋配方为奶粉14%、白砂糖13%、蛋黄2%和复合稳定剂0.2%时,添加3.0%(w/w)该淀粉酯的无奶油冰淇淋制品其融化率下降、膨胀率提高,口感更加清凉、细滑;其它不同替代程度的低脂冰淇淋制品品质也较优良,整体品质明显优于添加3.0%(w/w)马铃薯原淀粉作为脂肪替代品制得的冰淇淋制品。结论为高黏度辛烯基琥珀酸马铃薯淀粉酯可以作为脂肪替代品部分或全部代替冰淇淋配方中的奶油,但相应冰淇淋的硬度略有增加。 相似文献

The objective of this study was to examine consumer willingness to pay (WTP) for animal welfare in dairy production using nonhypothetical Vickrey auctions and open-ended choice experiments. Two hundred fifteen subjects participated in experimental sessions with 4 types of dairy products (humane animal care-labeled cheese and ice cream and conventional cheese and ice cream) and 4 valuation mechanisms. Information treatment, which included information about humane animal care principles in dairy production, was used to examine the effects of information on WTP. The results showed that participants, on average, were willing to pay extra for a scoop of humane animal care-labeled ice cream above the price of conventional ice cream. However, no premium WTP for humane animal care-labeled cheese was detected. Furthermore, provision of information only about humane animal care principles in dairy production, without corresponding information about conventional production practices, did not increase WTP for humane animal care-labeled products. 相似文献

This study attempted to investigate the possibility of using some types of probiotic bacteria in the production of ice cream and was aimed at making a contribution to the manufacture of new functional foods. For this purpose, different cream levels (5% and 10%) and different strains of probiotic bacteria ( Lactobacillus acidophilus , Bifidobacterium bifidum and both) were used in ice cream production to determine their effects on the quality of the ice creams in each group. During storage of 1, 15, 30, 45, 60, 75 and 90 days, L. acidophilus , B. bifidum counts and sensory analyses were performed. The results obtained at the end of storage demonstrated that the counts of L. acidophilus and B. bifidum continued to decrease during the storage but all types of ice cream sample seemed to preserve their probiotic property even after 90 days. Higher counts of probiotic bacteria were observed in the samples with L. acidophilus , B. bifidum , and L. acidophilus and B. bifidum in double-cultured samples respectively. In general, it appeared that the ice cream samples with 5% cream content were found to be more delectable. All ice cream samples have shown good results in preserving their probiotical properties for more than 3 months. Although sensory scores of probiotic ice cream samples reduced during this time, they rated as 'tasty' throughout the storage. 相似文献

研究了黄原胶和瓜尔豆胶的复配胶作为冰淇淋稳定剂对冰淇淋品质和流变性的影响,测定了冰淇淋浆料的粘度,应用小幅振荡测定经硬化后冰淇淋成品的动态粘弹性,以及硬化冰淇淋的硬度和粘结度.结果表明,随复配胶用量的增加,冰淇淋浆料的粘度也随之增加,另外,Power law模型的流动指数和粘度指数、冰淇淋成品储能模量、及硬度、粘结度均呈增加趋势.实验结果还表明,随复配胶用量的增加,冰淇淋的弹性模量和稳定性得以提高.通过测定冰淇淋的膨胀率和抗融性,得出冰淇淋中复配胶的最佳添加量质量分数为0.35%. 相似文献
