基于海藻酸钠与果胶在钙离子体系中协同生成凝胶的原理,利用反向成球技术,通过在海藻酸钠-果胶复合溶液中加入含钙芯液,制备具有核壳结构的海藻酸钠果胶复合凝胶小球,即核壳胶囊。采用流变仪和质构分析仪分别研究海藻酸钠-果胶复合溶液和芯液的流变性质及其对核壳胶囊质构特性的影响。结果表明,随着果胶在复配体系中所占的比例上升,复合溶液的粘度逐渐下降,最佳的复配比例为海藻酸钠:果胶=7:3(w/w),复合溶液浓度为0.6%,其质构特性的最大力值为(430.1±24.4)g·cm-2,外壳的咀嚼性数值为(1054.9±23.4)g;流变分析显示,当芯液中黄原胶浓度0.4%、乳酸钙浓度1.5%时,所制备的核壳胶囊具有最优的球度(达标率100%)和良好的质构特性(最大力值为(376.3±18.2)g·cm-2,咀嚼性为(1104.0±43.3)g)。 相似文献

Chitosan–pectin hydrogel beads that trap and release the maximal amount of combined garlic and holy basil essential oils to inhibit food microorganisms were developed based on the central composite design, with chitosan (0.2–0.7% w/v), pectin (3.5–5.5% w/v) and calcium chloride (CaCl2) (5.0–20.0% w/v) contents. The optimal bead consisted of 0.3–0.6% w/v chitosan, 3.9–5.1% w/v pectin and 8.0–17.0% w/v CaCl2, which had a high encapsulation efficiency (62.16–79.06%) and high cumulative release efficiency (31.55–37.81%) after storage at 5 °C for 15 days. Optimal hydrogel beads were packed into a cellulose bag to evaluate antimicrobial activity by the disc volatilisation method. The beads inhibited Bacillus cereus, Clostridium perfringens, Escherichia coli, Pseudomonas fluorescens, Listeria monocytogenes and Staphylococcus aureus but did not affect Lactobacillus plantarum and Salmonella Typhimurium. The oil-containing beads could potentially be applied in food packaging to inhibit the mentioned microorganisms. 相似文献

The effect of different hydrocolloids (pectin, carboxy methylcellulose, xanthan gum, and sodium alginate) pre-treatment used at different concentrations (0.2–0.4%) on instrumental texture parameters as well as on the sensory attributes of frozen-thawed pre-cut carrots was evaluated. Instrumental texture profile analysis of frozen-thawed carrot showed a significant (P < 0.05) increase in cohesiveness with an increase in the concentration of all the hydrocolloids. Nevertheless, the increase in springiness was not significant (P > 0.05) over the untreated control samples, whereas chewiness did not show consistent results with an increase of any of the hydrocolloids. As the concentration of hydrocolloids increased, the firmness values obtained by cutting the frozen-thawed carrot samples with a Warner Bratzler Blade were also found to increase. Higher texture retention after freezing and thawing was observed in xanthan gum (0.4%) pre-treated samples than other hydrocolloids used as well as than the control samples. It increased the firmness up to 196.2% than the control samples. However, 0.3% xanthan pre-treatment gave the best sensory results. Sensory acceptability increased on increasing the pectin and carboxy methylcellulose concentrations, while lower concentration levels of alginate pre-treatment showed higher sensory preference than the higher concentration levels. Based on the results, untreated frozen samples suffered from a detrimental texture and sensory deterioration during 15 months of frozen storage. The carrot tissue integrity was well retained during frozen storage in the hydrocolloid pre-treated samples. 相似文献
