Acceptability of a reformulated grain-based food:Implications for increasing whole grain consumption

Idli is a popular Indian breakfast dish consumed by many people all over the world,made from white rice(Oryza sativum)(75%–80%)and black gram(Phaseolus mungo)(20%–25%).Idli’s wide consumption makes it ideal as a model for studying acceptability of a food reformulated with whole grains.The objective was to compare acceptability regarding texture,color and sensory properties when white rice was replaced with brown rice at 5 replacement levels(0%(control),25%,50%,75%and 100%).Textural attributes and L*a*b*color values were measured by a texture analyzer and a Chroma meter,respectively.Informed and blind sensory tests were conducted.Instrumental hardness and gumminess were proportional to the level of whole grain replacement,while springiness and cohesiveness did not vary by replacement level.Liking ratings for overall acceptability were similar at the three lowest levels of brown rice replacement.Although brown rice replacement reduced the liking score for various sensory attributes,especially for 75%and 100%replacements,more than 90%of the panelists preferred brown-rice-blended idli as their first choice.There are ample opportunities to increase whole grain consumption through reformulation of regularly consumed traditional refined grain foods by partial or complete replacement with whole grains.©2013 Beijing Academy of Food Sciences.Production and hosting by Elsevier B.V.All rights reserved.

亚麻配合力研究

亚麻为人类创造出巨大贡献,在印度同世界上许多国家一样,亚麻也是重要的油料和纤维作物之一。随着各种遗传分析技术的发展,经济开发利用杂种优势导致产量的提高。然而对油麻两用的研究较少。因此本研究目的是对6个不同起源的油用型和纤用型亚麻进行配合力估份。

不同储存条件下沙棘果采收后腐烂情况研究

本文研究了采后的沙棘果实的储存情况。分别使用 4种包装袋包装的沙棘果实 ,同时储存在 3种不同条件下 (室温 ,冷藏与恒温 2 5℃ )。结果表明 :在冷藏条件下保存在纸袋中效果最好 ,其次是冷藏条件下保存在聚乙烯袋中。共检测到 2 9种真菌活性 ,其中链格孢菌 (Alternaria) ,镰孢菌 (Fusarium ) ,曲霉菌 (Aspergillus) ,黑附球菌 (Epicoccum) ,青霉菌 (Pencillium) ,茎点霉菌 (Phoma)是优势菌种。不同储藏条件下种子活力也不同。在布袋中冷藏的沙棘种子的根与芽生长受抑制情况最明显。在此条件下非正常种子数也最多。聚乙烯袋中 2 5℃恒温的种子萌发率最低。冷藏条件下纸袋中的沙棘果实质量最好 ,也更耐储存。

沙棘油对犬科动物(狗)消炎能力的评估

用沙棘种子油对狗 (12只 ,性别随机 )的急性消炎能力进行了研究。急性炎症试验部位都选择在狗的背部。使用游标卡尺连续 7d测量皮肤上发炎部位的情况来检测沙棘种子油的消炎能力。结果说明沙棘种子油有抗炎的能力。同时使用棉球肉芽肿瘤测定法测定了沙棘种子油对狗 (12只 )皮肤的慢急性炎症的消炎能力。沙棘油对狗皮肤慢性炎症的抗感染能力太弱以致于无法检测到。

用于水果初次包装的活性包装纸的机械性能和抗菌效果研究

0引言言活性包装(Active Packaging)又称AP包装,属于一种智能型包装,是指在包装袋内加入各种气体吸收剂和释放剂,以除去过多的CO2、乙烯及水气,并及时补充O2。

Effective Use of Near Real-time Monitoring System for Stunting Reduction in Zimbabwe

Background:In Zimbabwe,26.2 percent of children under five are stunted.Evidence has shown that multi-sector interventions are key to addressing stunting.Yet,practical implementation is difficult,often occurring through separate disjointed and uncoordinated sector actions with limited access to real time information for decision-making.Objective:To describe the design,implementation,successes,challenges and lessons learned from using a near-real time monitoring(NRTM)system as a monitoring tool for multi-sectoral community based model for stunting reduction in Zimbabwe.Methods:An open source technology was used to obtain the information needed on the multi-sectoral coordination process,provide a common platform to capture and present data on situational factors,community conditions and practices to be acted upon and thus contribute to reducing stunting.Results:Significant improvements in community data flows were noted;the system brought together several types of data,concepts,stakeholders and multi-sector energies into focused programming.Several challenges including conceptual issues,initial coordination,financial resources and missed partnership opportunities were documented.The introduction of the NRTM system resulted in improved data flows for programme monitoring and facilitated multi-sector collaboration.Conclusion:NRTM is an effective monitoring tool for the multi-sectoral community based model to reduce stunting in Zimbabwe.
