大麦和麦芽质量评价的最新发展

公认的大麦和麦芽分析方法既起到作为商业交易的基准又起到作为对过程特征和成品质量预料的双重作用。麦芽制造和啤酒酿造的加工技术改变－特别是，生产周期的缩短和啤酒无菌过滤匠引进－已经着眼于提高对原料质量方面的要求和促使探索对质量评价的新途径。     

用麦芽根调节水分对啤酒糟混贮品质的影响

将啤酒糟和麦芽根按不同比例袋装混贮,分别在30、60、90、120 d开袋取样进行感官评定,pH值、氨态氮、干物质、粗蛋白、中性洗涤纤维及有机酸含量分析。结果表明:混贮时间和水分含量均对混贮效果有显著影响;混贮饲料在混贮前60 d各指标变化范围较大,60 d后变化范围较小,并逐渐趋于稳定状态;混贮饲料以含水量50%的袋装混贮效果最好,其次是60%、40%,70%最差。     

应用正交试验设计及数理统计法对全酶法生产高麦芽糖浆工艺的研究

本文阐述了怎样用植物酶系补充异淀粉酯的缺乏及β—淀粉酶的不足用于制取高麦芽糖浆,并用正交法进行试验设计及数理统计,大大降低了项目科研成本。     

富硒麦芽对二乙基亚硝胺致SD大鼠肝癌细胞因子和血管生成的影响

雄性SD大鼠193只，体质量100～120g，随机分为5组。Ⅰ～Ⅲ组，日粮中添加富硒麦芽至硒含量分别为0．3、1．0、3．0mg／kg；Ⅳ组为模型组；Ⅴ组为正常对照组，不加硒也不诱癌，日粮中分别添加亚硒酸钠至硒含量达0．1mg／kg。Ⅰ～Ⅳ组，饮水中添加二乙基亚硝胺（diethylnitrosamine，DEN，100mg／L）诱癌，维持DEN摄入量按体质量每天约10mg／kg，连续16周，然后改饮普通灭菌水至18周末。Ⅴ组始终以普通灭菌水自由饮用。每4周每组取5只鼠眼眶采血；18周末采血、处死所有大鼠。测定血清肿瘤坏死因子α（tumor necrosis factor-α，TNFα）、白介素-2（interleukin-2，IL-2）、胰岛素样生长因子-Ⅱ（insulin—like growth factor-Ⅱ，IGF-Ⅱ）、一氧化氮（nitricoxide，NO）、一氧化氮合成酶（nitric oxide synthase，NOS）等的含量，并以免疫组化法观察大鼠肝肿瘤组织血管内皮生长因子（vascular endothelial growth factor，VEGF）的表达。结果发现，某些剂量富硒麦芽能有效地抑制肝癌大鼠TNFα、IGF-Ⅱ、NO和NOS水平的上升，提升血清IL-2水平，抑制肝肿瘤组织中VEGF的表达。结果提示，富硒麦芽能促进肝癌大鼠免疫功能，抑制肿瘤血管生成，从而发挥其抗癌作用。

异麦芽低聚糖对断奶仔猪肠道菌群及腹泻的影响

选 35± 2日龄仔猪 4 0头 ,随机分成 5组。 1组为对照组 ,喂基础日粮 ,2～ 5组为试验组 ,在基础日粮基础上分别添加 0 .1%、0 .2 %、0 .4 %和 0 .8%异麦芽低聚糖浆 (含异麦芽低聚糖 77.0 7% ) ,测肠道菌群浓度、蛋白酶活性、肠绒毛高度、小肠隐窝深度、生产性能、腹泻指数、相关血液指标及粪氨含量。试验结果表明 ,4、5组肠道菌群、小肠绒毛高度、小肠隐窝深度、蛋白酶活性、饲料转化率等指标显著优于其它组 (P <0 .0 5 ) ;5组尿素氮显著低于其它组 (P <0 .0 5 ) ,血钙浓度、平均日增重与采食量显著高于其它组 (P <0 .0 5 ) ;4组腹泻指数和粪氨含量显著低于其它组 (P <0 .0 5 )。     

芝麻酥糖的加工

芝麻酥糖为山东省曹县传统历史名吃,始于明未清初,是一种历史悠久,工艺考究的糖制食品,具有香甜酥脆、味美可口的特点。它不仅营养丰富,而且能治疗消化不良,伤风咳嗽等疾病,老少皆宜食用。制作芝麻酥糖成本低,效益高,适合农村家庭生产,6个人的作坊每天加工生产50千克-100千元,每千克成本2.5元-3元,售价8元-10元。现将加工工艺介绍如下:     

Comparison Study on Effects of Three Chinese Herbal Medicine on Intestinal Morphology in Weaning Piglets

The objective of this study was to compare the effect of three Chinese herbal medicine (medicated leaven, hawthorn, fructus hordei germinates) on histomorphology of different parts of small intestine in weaning piglets.40 28-day old ternary pigs (Duroc×Landrace×Yorkshire) with the body weight (8.13±1.32)kg were divided into four groups, control group, medicated leaven group, hawthorn group and fructus hordei germinates group, and feeding with 1% Chinese herbal medicine, there were two repeats in each group and each repeat had 5 piglets, slaughtering and sampling at 7th and 14th day morning, respectively, sections were used for HE staining.The staining tissues were taken pictures under a microscope camera (200×) and measured VH, CD, IWT and V/C in different parts of small intestine with Image-Pro Plus.The result showed that the IWH of ileum in medicated leaven group was significantly or extremely significantly higher than control group (P<0.05;P<0.01).The VH and IWT of duodenum and jejunum at 7th day in hawthorn group were extremely significantly lower than control group (P<0.01);The IWT of ileum and the VH of ileum at 14th day were extremely significantly higher than control group (P<0.01).In fructus hordei germinates group, the VH of duodenum and jejunum at 7th day and IWT of jejunum were extremely significantly lower than control group (P<0.01);The CD of ileum at 7th day, the IWT of duodenum and ileum at 7th day were extremely significantly higher than control group (P<0.01).The effects of different simple Chinese herbal medicine on histomorphology of different parts of small intestine in piglets were different, because of the different digestive functions of small intestine, the most effects of Chinese herbal medicine an duodenum, jejunum and ileum were fructus hordei germinates, medicated leaven and hawthorn, respectively.
