采用中草药物复合纸的保鲜效果研究 总被引:3,自引:1,他引:3
以具有优良防霉抑菌作用的几种天然中草药为保鲜材料,分别选用中草药熬取液浸果和以中草药粉末复合纸保鲜包装两种形式保鲜。通过与不经任何处理仅以纸包装的对照组对比,试验结果表明,这些中草药具有良好的保鲜效果,尤其是以中草药复合的功能保鲜包装纸,保鲜效果明显,以鸭梨为试验样品,在室温30℃左右放置35天以上,样品仍能保持较好的鲜度,营养成份损失不大。 相似文献

休眠法保鲜水果的研究 总被引:1,自引:0,他引:1
本文介绍了现代休眠法保鲜甜柑、苹果、蜜桔的方法。这种方法是在包装的水果箱内同时使用降温剂、降氧剂、吸水板、二氧化碳吸收剂、乙烯吸收剂,达到较长时间保持水果的色、香、味不变,营养成分变化不大,烂果率低的效果。本法保鲜水果的手续简便、费用低,是一种很有发展前途的保鲜水果的新方法。 相似文献

In this study, the physical properties of samples of ice cream produced from yogurt with varying levels of sugar (18, 20 or 22%) and fruit (strawberry) concentration (15, 20 or 25%) were investigated. The results of the physical analysis indicate that as the amount of sugar and fruit increases, there is an increase in the first dripping time period, viscosity values and the overrun. However, complete melting times decreased in parallel with the increase in sugar content and fruit concentration. It was observed that an increase in the amount of sugar in vanilla frozen yogurt softened the structure. In strawberry ice-cream-type frozen yogurt, the structure hardened in parallel with the increase in fruit concentration. In addition, the results show that frozen yogurts with high sugar (V3) and fruit (St3) concentrations are the type most preferred by the panellists. The results of the sensory analysis suggest that frozen yogurt can be an alternative to other dairy products such as yogurt and ice cream. 相似文献

A method recently developed for the determination of the fruit content of strawberry fruit preparations by gravimetric quantification of hemicellulose was extended to cherry fruit preparations. Isolation of the alcohol-insoluble residue (AIR) and sequential fractionation of the cell wall compounds from cherries (Prunus cerasus L. cv. ‘Oblacinska’) was performed yielding the amount of fresh cherries per gram hemicellulose. Cherry fruit preparations with varying fruit contents (30–40%) were produced using different hydrocolloid systems (pectin, starch, guar gum, xanthan gum, carrageenan, and combinations thereof). After separation of the hydrocolloids by enzymatical digestion and successive extraction, the fruit preparations were subjected to AIR isolation. The AIR was fractionated to yield the hemicellulose fraction, which was quantified gravimetrically for the calculation of the fruit content. Compared to strawberries, modifications including additional extraction steps for the sequential fractionation were required to separate the pectin of the cherries exhaustively. Calculated and initial fruit contents were in good agreement for the single hydrocolloid components pectin and starch as well as for the combinations pectin/xanthan gum and pectin/carrageenan (26.8% vs. 30%, 38.6% vs. 40%, 42.5% vs. 40%, 37.6% vs. 40%, and 41.2% vs. 40%), whereas the preparations produced with more complex hydrocolloid systems (pectin/xanthan gum/guar gum and starch/xanthan/guar gum) showed larger deviations in their contents (46.2% vs. 40%, 49.6% vs. 40%). It is concluded that the novel method is generally suitable for the determination of the fruit content of fruit preparations, but steps of sample preparation need to be individually adapted to the different fruit matrices. 相似文献
