棉藕丝混纺系列产品的开发

介绍了藕丝纤维的性能特征.由于藕丝纤维粗、刚性大、可纺性差,纺纱前必须进行预处理使其软化,以提高其可纺性.藕丝单独成卷及梳理成条均较困难,所以采取棉包混和.棉与藕丝混纺纱系列产品,布面粗犷、朴素、自然,与我国独特的手工织物风格相似,市场前景广阔.     

荷叶提取液的抑菌特性研究

为研究荷叶提取液对大肠杆菌的抑制特性,进行了不同提取液浓度、培养基pH值、热处理、环境离子浓度、作用时间对荷叶提取液抑菌作用影响的试验。结果表明:荷叶提取液对大肠杆菌的最低抑菌浓度(MIC)为0.125g/mL;抑菌pH值范围6～9;对高温处理较稳定;钠离子和镁离子的浓度对抑菌效果的影响不大;提取液与菌悬液作用3h可抑制大肠干菌的生长,从而说明荷叶提取液对大肠杆菌有较好的抑菌效果,且受环境条件的影响较小,为荷叶天然食品防腐剂的开发提供了理论基础。

Lotus (Nelumbo nucifera Gaertn) plumule polysaccharide protects the spleen and liver from spontaneous inflammation in non-obese diabetic mice by modulating pro-/anti-inflammatory cytokine gene expression

A novel lotus plumule polysaccharide (LPPS) was administered to non-obese diabetic (NOD) mice for 15 weeks to evaluate the protective effects of LPPS on type 1 diabetes. After the 15-week feeding experiment, tumour necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 expressions in the spleen, liver and kidney of the experimental mice were measured using enzyme-linked immunosorbent assay or real-time quantitative polymerase chain reaction assay. The results showed that LPPS significantly (p < 0.05) decreased the absolute weights of the enlarged spleens in the NOD mice in a dose-dependent manner, inhibited pro-inflammatory TNF-α and IL-6 cytokine production and decreased the secretion ratio of IL-6/IL-10 in splenocyte cultures. LPPS markedly decreased the relative expression of pro-/anti-inflammatory cytokine genes (TNF-α/IL-10 and IL-6/IL-10) in the livers of NOD mice. Our results suggest that LPPS protected the spleen and liver from spontaneous inflammation in NOD mice by modulating pro-/anti-inflammatory cytokine gene expression.

Oxidative and color stability of cooked ground pork containing lotus leaf (Nelumbo nucifera) and barley leaf (Hordeum vulgare) powder during refrigerated storage

This study aimed to evaluate the oxidative and color stability of cooked ground pork containing lotus leaf powder at 0.1 (LP1) and 0.5% (LP2) as well as barley leaf powder at 0.1 (BP1) and 0.5% (BP2) during refrigerated storage for 10 days. The oxidative stability of these powders was compared with butylhydroxytoluene (BHT). LP1 had higher a* and lower b* values than the control (-) over 4 days (p<0.05). The pH values of the ground pork samples made with addition of LP and BHT decreased until day 4 and then increased. Thiobarbituric acid-reactive substance (TBARS) values were lowest in LP2 on day 10 (p<0.05). The ground pork samples containing LP and BP had lower peroxide values (POVs) and conjugated dienes (CD) compared to the control (-).These results indicate that LP or BP can be incorporated into ground pork to effectively retard oxidation after cooking.
