食品安全与食品低温流通中的温度监控

食品的温度监控是一种有效的保证食品安全及保持冷藏链完整的手段,对冷冻冷藏食品在低温流通过程中实行温度监控是非常有必要的。目前,我国冷藏运输中的温度管理情况并不乐观,消费者获得的货物通常不能达到预计的要求。要解决这一问题,必须要借助于时间-温度指示器等来对其整个运输过程进行温度监控。本文对温度立法的必然性和前景,温度监控的重要性、原理以及在冷藏运输中的应用作了较详尽的介绍,并列举了几种国外时间-温度指示器的工作原理。

Antioxidant,anti-amylase and anti-glycation potential of brans of some Sri Lankan traditional and improved rice (Oryza sativa L.) varieties

Brans of 23 traditional and 12 improved (both red and white) rice varieties in Sri Lanka were screened for anti-amylase and anti-glycation activities in vitro. Varieties which showed the highest inhibitory activities at screening were further investigated for anti-glucosidase and glycation reversing as anti-diabetic properties. The same varieties were studied for selected antioxidant properties. Significantly high anti-amylase and anti-glycation activities were observed for bran extracts of red varieties compared to white varieties at screening. Traditional red rice varieties, Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti, exhibited significant and dose dependent anti-amylase, anti-glycation and glycation reversing activities. These varieties also showed marked antioxidant properties. It is concluded that brans of Sri Lankan traditional red rice varieties Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti may be potential food supplements for diabetes.     

Lighting Design of Chinese Traditional Buildings and Application of New Type of Little Power LED

This paper is a part of the research on the lighting techniques of the traditional Chinese buildings in Summer Palace,Beijing,which is a sub-project of the Municipal Research Project on the Correlative Techniques for Beijing's Sustainable Development(Y0604017040391).The work,which the authors took part in,on the most representative Chinese traditional buildings in Summer Palace,is taken as a case study on lighting design and lab simulated experiments and checked by practical result,illustrating a working frame for other similar lighting design works.     

Effect of Western Architectural Culture on the Traditional Dwellings in Meizhou

Under the special social background and source of history, the western architectural culture affected the traditional dwellings in Meizhou from the 19th century till the 20th century. The framework, outline and materials of traditional dwellings were changed in certain extent while the form of plane layout and interior decoration still stood stable maintaining the native characters. This article analyzes the phenomena of incorporation of things with diverse nature.     

农产品加工中的营养学思考与营养食品生产

中国农产品生产及其加工曾经经历过注重产品数量扩增、技术设备改进和卫生安全的发展阶段,目前正处在挑战和发展机遇并存的转折时期.中国农产品生产及其加工业应把握时机,应用营养科学为指导,科学地制定"十一五"期间的发展战略,丰富和发展营养食品产业,促进农产品生产和加工全面满足人民营养健康需要和市场需求,这将是开拓发展领域,实现产品升级换代,提升竞争能力和增值潜力,主动迎接国际挑战的战略举措,也是实践"以人为本"的科学发展观的具体体现.     

高压静电场处理对葡萄鲜度保持的影响

以巨丰葡萄为材料,研究了在20kV/m,40kV/m,60kV/m,80kV/m,100kV/m不同高压静电场处理1h对葡萄的质量损失率、腐烂率、掉果率的影响.试验结果表明:高压静电场处理对葡萄质量损失有明显的抑制作用;并且能够延迟葡萄采后的衰老过程,葡萄的腐烂率、掉果率明显低于对照;在相同贮藏条件下,利用60kV/m的高压静电场处理,葡萄的保鲜效果好于其它高压静电场处理,葡萄贮藏70天,好果率达80%.
