Cryoprotective Effects of Sugar, Polyols, and/or Phosphates on Alaska Pollack Surimi

Freeze-induced protein denaturation of pollack surimi was investigated as affected by the addition of sugar and/or polyol, including a starch hydrolysate product, and/or phosphates during 8 months frozen storage. Polydextrose® appeared to substitute for the sucrose/sorbitol now used in surimi manufacture without changes in cryoprotective effect. The maltodextrin adversely affected gel-forming properties, although it maintained the salt-soluble protein extractability nearly as well as did sucrose/sorbitol or Polydextrose®. The cryoprotective effects of phosphate addition seemed to depend upon the pH and/or specific phosphate ion used.     

Edible Coating Effects on Storage Life and Quality of Tomatoes

Tomatoes at breaker and pink stage maturities were coated with comzein film. Color, weight and firmness changes and sensory quality were compared with noncoated tomatoes during storage at 21°C. Corn-zein fdm delayed color change and loss of firmness and weight during storage. Shelf life was extended by 6 days with film coatings as determined by sensory evaluation.     

DRY BEAN (PHASEOLUS VULGARJS) COLOR STABILITY AS INFLUENCED BY TIME and MOISTIJRE CONTENT

The color stability of 32 lines of beans to which different levels of moisture were added was evaluated in an accelerated shelf-life testing chamber for up to 10 weeks using Hunter values and National Bureau of Standard (NBS) unit of color difference (± E) techniques. With pinto beans, Hunter L values decreased as storage time increased. Also, Hunter a values increased with time. However, Hunter b values did not change with storage. With great northern beans, Hunter a and b values were more important than Hunter L value. Similar to pinto beans, along with prolonged storage, great northern bean color changed. Pinto and great northern beans having an extra 10% added moisture showed much more color change than those of control or 5% moisture added beans. Finally, bean genotype was closely related with color stability in stored pinto and great northern beans.     

细粒度与可视化的“比”字句分析模型及计算应用

针对现有五元组比较句语义要素框架的缺陷,该文引进了提升语义分辨率的七元组语义要素分类模板。在此基础上建立了一个可视化的“比”字句结构分析模型,用以总结出比较对象之间的三种对应模式,并确立了判定“不对称比较”的形式标准。该文的可视化分析模型可以明确阐述“比”字句内部的多重述谓结构,有助于获取容易被忽略或认错的隐含成分及比较关系。而且,它立足于谓词逻辑的基础形式,所以与OWL本体语言相兼容。作为模型的应用实践,该文还建设了小规模知识本体(ontology),演示了“比”字句语义要素的自动识别过程。
