The effects of zero-trans chemically interesterified (in-es) and non-interesterified (non-in-es) cottonseed (CO), hazelnut (HO) and olive oil (OO) and their blends (25, 50 and 75%) with palm oil (PO) were studied in the production of cookies. All the experimental shortenings had zero-trans fatty acids (TFA) while the shortening contained 14.20% TFA. Incorporation of CO in PO considerably increased the linoleic acid content whereas the raising of HO and OO ratio in the blend increased the oleic acid content. Zero-TFA and lower saturated /unsaturated fatty acid ratio (SFA/UFA) of some of the experimental shortenings indicated an important in nutritional properties of cookies produced from these experimental shortenings. Cookies with in-es shortenings showed significantly higher (p < 0.05) spread ratios and L Hunter color than their non-in-es shortenings added counterparts. It can be concluded that chemical interesterification is a promising method to produce cookie shortenings with zero-TFA.
研究了零反式化学酯交换(in-es)和非酯交换(non-in-es)棉籽油(CO)、榛子油(HO)和橄榄油(OO)及其与棕榈油(PO)的混合物(25%、50%和 75%)在曲奇生产中的效果。所有实验性起酥油均不含反式脂肪酸(TFA),而普通起酥油含有 14.20%的 TFA。CO 加入 PO 中会大大增加亚油酸的含量,而 HO 和 OO 比例的增加会增加油酸的含量。一些实验性起酥油的零 TFA 和较低的饱和/不饱和脂肪酸比例(SFA/UFA)表明,用这些实验性起酥油生产的曲奇具有重要的营养特性。in-es 起酥油制成的曲奇的扩展比和 L Hunter 颜色显著高于添加了 non-in-es 起酥油的曲奇(p<0.05)。可以得出结论,化学酯交换是生产零 TFA 曲奇起酥油的一种有前途的方法。
