研究发酵蔬菜汁替代化学合成亚硝酸盐在牛肉肠中的作用效果。以木糖葡萄球菌和肉葡萄球菌作为发酵剂,不同添加量(5%、10%、15%和20%)的菠菜汁和胡萝卜汁为试验组制作牛肉肠,添加亚硝酸盐(添加0.01%)组为对照组,通过模糊综合评价法和牛肉肠的亚硝酸盐含量筛选最佳蔬菜汁;比较无亚硝酸盐蔬菜汁组、亚硝酸盐蔬菜汁组和发酵蔬菜汁组3种不同处理方式的牛肉灌肠在贮藏期间菌落总数、TBARS值、TVB-N、p H和色差的变化。添加15%和20%发酵菠菜汁制作的牛肉灌肠感官评价均较好,但是20%的发酵菠菜汁在24 h的亚硝酸盐残留量达到31.137 mg/kg,超出国标允许范围内,所以选择15%的发酵菠菜汁。在贮藏过程中,添加15%发酵菠菜汁制作的蔬菜牛肉发酵肠的微生物指标、理化指标和肉色指标与添加0.01%亚硝酸盐制作的牛肉灌肠相当。本研究得出在牛肉灌肠制作中,供试菌发酵15%菠菜汁产生亚硝酸盐可替代直接添加0.01%化学合成亚硝酸盐。 相似文献

Objective quality of ultrafiltered (UF) apple juice compared favorably to apple juice filtered by conventional plate and frame filtration (PF). Agtron red and green values were higher for the UF juice, indicating a lighter colored product. Agtron green values were lower after 4 months of storage and compared well to juice from conventional methods over the remaining 8 months of storage. Green color of the UF juice remained steady at storage temperatures of either 1° or 21°C and was equal to the color values of the conventional juice stored at 1°, 21° or 32°. Clarity of the UF juice was excellent and remained stable over the entire storage period at either 1 or 21° with only a slight drop in clarity at 32°. UF juice was rated significantly lower in sensory flavor than PF juice. Sensory color of the UF juice was not rated as high as the PF juice at the start of the study, but as time in storage progressed sensory color improved. Initial panel reaction to UF apple juice was that the UF juice was too light in color and watery in flavor. 相似文献

通过感官评价,综合基本理化指标得出了一种较优的绿色复合果蔬汁的配方,并对比超高压(high hydrostatic pressure,HHP)和高温短时杀菌(high temperature short time,HTST)处理前后及其在4 ℃贮藏过程中的杀菌效果和理化品质变化。结果表明:对复合果蔬汁分别进行HHP(600 MPa/5 min)处理和HTST杀菌(86 ℃/15 s)处理后,果蔬汁中菌落总数从5.18 lg CFU/mL,下降至1.07 lg CFU/mL和1.11 lg CFU/mL,霉菌酵母、乳杆菌和嗜冷菌均未检出,达到国家要求的果蔬汁卫生标准;HHP处理后的果蔬汁总酚含量为43.645 μg/mL,显著高于HTST绿色复合果蔬汁;与HTST处理相比,HHP处理可以更好地保持复合果蔬汁的悬浮稳定性、色泽和抗氧化性等营养和品质指标。在4 ℃,15 d的贮藏期间,经HHP处理和HTST杀菌后的复合果蔬汁微生物指标均未超出国家卫生标准,且经HHP处理后的复合果蔬汁的悬浮稳定性、色泽品质、总酚含量和抗氧化能力等各项品质指标均优于HTST杀菌组。因此,HHP绿色复合果蔬汁保持了更好的品质。 相似文献

The quantities of protein which can be extracted from green plants depend on a number of factors such as the botanical composition of the plant, its growth stage, topdressing and system of extraction. Leaf protein concentrates have been incorporated into food for human consumption, but their green color has limited its application. Thermal precipitation of chloroplastic material is not specific, causes denaturation and requires high energy input. A selective recovery of the green fraction is possible by centrifugation at high centrifugal forces or by the combination of this method with an addition of calcium salt to a green juice. Application of high molecular polyelectrolytes in green juice precipitation allows the separation of pigmented material at room temperature. The objective of this work was to determine the effect of cationic and anionic flocculants on fractionation of alfalfa green juice into two fractions: chloroplastic (green LPC) and cytoplasmatic (white LPC). 相似文献

The potential of potato juice in relieving gastrointestinal disorders has already been proven. Work continues on implementation of this active component into products that are widely consumed. In this article, results of an attempt to fortify pasta with potato juice are presented and discussed. Fortification is performed using fresh and dried juice. The influence of the addition on culinary properties of the final product, such as cooking weight and cooking loss, as well as microstructure, color, texture, and consumer acceptance were evaluated. It was found that potato juice can be used for fortification of pasta both in its fresh and dried forms, however the effects on different responses depend on the potato juice form used. The addition of potato juice influenced the color of the product reducing its lightness and shifting color balances from green to red, yellow color saturation was decreased as well. Changes in color were more significant in the case of fresh juice addition. The firmness and microstructure of pasta was also influenced. The surface microstructure of pasta containing fresh potato juice was different from that of the other 2 products being a likely explanation of the lower cooking loss observed in its case. In contrast, the consistency of dough was strengthened by addition of dried potato juice. Principal components analysis indicated that the color change had the most pronounced effect on consumer acceptance. Other physicochemical changes were slightly less significant. Nevertheless, sensory evaluation proved that functional pasta produced with fresh potato juice finds consumer acceptance comparable with that of classic pasta. 相似文献

The quantities of protein which can be extracted from green plants depend on a number of factors such as the botanical composition of the plant, its growth stage, topdressing and system of extraction [1, 7, 8]. Leaf protein concentrates have been incorporated into food for human consumption, but their green color has limited its application [6, 9]. Thermal precipitation of chloroplastic material is not specific, causes denaturation and requires high energy input [9]. A selective recovery of the green fraction is possible by centrifugation at high centrifugal forces or by the combination of this method with an addition of calcium salt to a green juice [3, 4]. Application of high molecular polyelectrolytes in green juice precipitation allows the separation of pigmented material at room temperature [2, 5]. The objective of this work was to determine the effect of cationic and anionic flocculants on fractionation of alfalfa green juice into two fractions: chloroplastic (green LPC) and cytoplasmatic (white LPC). 相似文献
