该文对甘薯渣中膳食纤维进行提取及酶改性,将改性后的膳食纤维用于制作酥性饼干,通过单因素试验和正交分析得到饼干的最优工艺参数。结果表明,酥性饼干最优制作参数为主料94%低筋面粉、6%酶改性甘薯渣膳食纤维粉,辅料(以主料质量百分比计)0.65%小苏打、1.2%泡打粉、20%鸡蛋液、45%黄油及45%白砂糖。相同条件下,对未添加膳食纤维、添加改性膳食纤维及添加未改性膳食纤维3种酥性饼干进行品质特性分析,结果表明,添加改性膳食纤维会使酥性饼干内部结构更疏松,同时改性膳食纤维对酥性饼干直径和厚度、色度、出品率及质构均有一定影响。 相似文献

为了改良青稞粉的品质以及青稞加工制得的饼干粗糙、较难下咽的口感问题,采用转谷氨酰胺酶对青稞粉进行半固态发酵,考察发酵前后青稞粉的品质及青稞饼干的口感。通过综合评价发酵前后青稞粉的谷蛋白溶胀指数、保水力和总糖含量,确定转谷氨酰胺酶的较佳发酵工艺条件;并比较发酵与未发酵青稞粉制得的饼干感官得分。结果表明,转谷氨酰胺酶发酵温度25℃,酶处理时间5 h,酶质量分数0.3%条件下,谷蛋白溶胀指数为3.36、保水力为60.70%,总糖质量浓度为7.19 mg/mL。与未发酵时相比,发酵青稞粉制得的饼干在制作过程中更易形成面筋,且口感更佳,香气怡人。 相似文献

Sugar inhibits gluten development during dough mixing by competing with the flour for the recipe water, resulting in less tough and more crumbly biscuits. Commercially available Raftilose, which acts as an oligofructose and a sugar replacer was used in the recipes where the sugar was reduced by 20–30%. It was found that the sugar replacer did not exert the same hardening effect on the dough as the granulated sugar, therefore values for dough hardness were found to be lower than those obtained for the standard biscuit. Peak force values of the reduced sugar biscuits were found to be significantly lower than the control biscuit (P<0.05), indicating a lower snapping characteristic, and therefore softer eating characteristics. Only those biscuits with the highest level of sugar replacement showed different surface colour attributes. At the lower and medium levels of sugar replacement, oligofructose can be used successfully to reduce sugar in short dough biscuits. 相似文献

花生粕是花生榨油后的副产物,压榨过程中高度变性导致蛋白利用率较低。本文通过生物发酵技术诱导米曲霉分泌蛋白酶水解花生粕,在不同底物浓度条件下酶解花生粕,对比酶解产物的蛋白回收率、水解度、总糖回收率、分子量分布、游离氨基酸组成,同时采用电子舌对富含呈味肽的酶解产物进行感官评价分析,探究不同底物浓度条件下发酵花生粕的酶解产物特性,并筛选适宜的酶解浓度。研究发现,发酵花生粕经不同底物浓度酶解后,蛋白回收率在70.68%~84.14%之间,水解度在30.04%~40.05%之间;酶解产物以小于1 ku的短肽为主(87.57%~90.21%),并含有较多游离氨基酸;在呈味特性方面,酶解液含有较强的鲜味。结果表明,在料液比为1:5时,获得较高的蛋白回收率、水解度以及较多小分子肽,鲜味评分也相对较高。 相似文献

Degradation of aflatoxins by extrusion cooking: Effects on nutritional quality of extrudates 总被引:1,自引:0,他引:1
Extrusion of artificially contaminated food is reported to degrade aflatoxins to varying degrees depending on the extrusion conditions. This work sought to determine the (1) efficacy of extrusion cooking in destroying naturally contaminated peanuts and (2) nutritional quality of decontaminated peanut meal. Naturally contaminated peanut meal was extruded by varying the moisture (20, 28, 35 g/100 g), pH (7.5, 9.5) and extruder die diameter (2.5, 3, 3.5, 4.0 mm). Aflatoxins levels in the extrudates were determined using HPLC procedures, and the nutritional quality was assessed using in-vitro methods. The highest aflatoxin reduction in naturally contaminated peanut meal was 59% at feed moisture content of 35 g/100 g. Higher (91%) reduction was achieved in the artificially contaminated peanut meal at moisture of 20 g/100 g. In-vitro protein digestibility and Fluorodinitrobenzene (FDNB)-available lysine of the extrudates were not significantly different from non-extruded peanut meal. Extrusion conditions for aflatoxin reduction did not adversely affect protein nutritional quality. 相似文献

Composite flours containing wheat, breadfruit flour and soy protein, whey or peanut meal were formulated and incorporated into western style bread and biscuits. Bread containing 10% breadfruit flour and 5% whey, and biscuits containing 10% breadfruit flour and 5% soy protein were judged most acceptable in flavor, color, and texture. Breadfruit flour contained 4.4% protein and was lower in sulfur containing amino acids and higher in lysine than wheat flour. Breadfruit containing bread and biscuits had low amino acid scores. The protein efficiency ratio (PER) of the biscuit product, however, was similar to that of the casein control while the PER of bread was significantly lower. Results suggest that acceptable products can be made with composite flours containing 10% breadfruit flour. 相似文献
