Cottonseed protein: What does the future hold?

Cottonseed protein has the potential to increase the world's food supply while decreasing the incidence of malnutrition among the world's hungry. Nutritionally, cottonseed flour compares favorably to other animal and vegetable protein sources, as it is low in fat and contains a substantial amount of high biological value protein. Animal studies, as well as human research, using gossypol-free glandless cottonseed flour have shown that cottonseed protein promotes growth, increased weight gain, and a positive nitrogen balance. Cottonseed protein food products have been shown to be a healthy addition to the diets of children, college-age women, and the elderly. With its light color and bland flavor, cottonseed has many uses in the food processing arena. Baked goods, snack foods and candy, as well as pet and livestock feed are just a few successful products developed utilizing cottonseed protein.

目的]研究优化艾草南瓜保健蛋糕的制作工艺.[方法]以艾草、南瓜、面粉、鸡蛋为原料,采用单因素试验和L9(34)正交试验,探讨面粉与艾草用量、南瓜泥添加量、鸡蛋添加量、白砂糖添加量对艾草南瓜保健蛋糕品质的影响.[结果]试验表明,制作艾草南瓜保健蛋糕的最佳工艺参数为:面粉+艾草用量为(30+ 10)g,南瓜泥添加量为50 g,鸡蛋添加量为300 g,白砂糖添加量为30 g.[结论]研究可为艾草南瓜保健蛋糕的生产提供一定的理论依据.     

海湾生态系统健康评价研究进展

海湾在生态系统中占有重要地位,其健康状况研究受到越来越多的关注。该研究回顾了生态系统健康的定义和进展,阐述了海湾生态系统健康评价的两种方法,其中指示物种法从单物种和多物种指示物种法2个方面进行对比分析,多指标综合指数法从综合指数法、活力组织恢复(Vigor-organization-resilience,VOR,结构功能)法和压力状态响应(Pressure-State-Response,PSR模型)法3个方面进行阐述。同时,讨论了海湾生态系统健康评价在近海水产增养殖中的应用,展望了海湾生态系统健康评价的研究方向。     

浙江海域虾姑中重金属镉的监测及健康风险评估

[目的]监测浙江海域中虾姑的重金属镉的含量,并对其健康风险进行评估。[方法]以浙江附近海域捕获的虾姑为材料,根据GB5009.12-2010中的石墨炉原子吸收光谱法测定其体内的重金属镉含量,并利用健康风险指数的方法对多个菜场或码头采来的虾姑中镉的健康风险进行评估。[结果]试验发现,所采集的海捕虾姑样品中镉含量都符合国家规定标准,各个虾姑样品的健康风险指数均小于1,按照平均摄入量来计算,每个虾姑都是处于安全水平的。[结论]浙江海域虾姑镉含量未超标,健康风险指数也在安全范围内,且营养丰富,但摄入也应有一定的限值。     

Rye phenolics in nutrition and health

Dietary intake of whole-grain foods is associated with a decreased risk of chronic diseases such as diabetes, obesity and heart disease. In addition to dietary fibre, various phytochemicals have been suggested to contribute to the health effects of whole grain products. This review focuses on phenolic compounds in rye (Secale cereale L.), which is one of the major bread grains in Europe. Data on phenolic concentrations in rye grain and foods, their bioavailability to tissues and effects in vivo, and their potential contributions to health are presented. Phenolic compounds in rye, such as phenolic acids, alkylresorcinols and lignans, are concentrated in the outer layers of the grain. Phenolic acids are the major phenolic compounds in whole grain rye (103–300 mg/100 g grain), ferulic acid being the most abundant. Rye lignans are present at concentrations of 2 mg/100 g grain and had been shown to be converted by the intestinal microflora to the mammalian lignans enterodiol and enterolactone in human intervention studies. Alkylresorcinols (36–320 mg/100 g grain), which have been found to be incorporated into human erythrocyte membranes, are of particular interest due to their potential use as biomarkers of the intake of rye and wheat.     

黄芪·蒲公英等中草药配伍对肉仔鸡生长保健性能的影响

[目的]探讨黄芪、蒲公英等中草药对肉仔鸡生长保健性能的影响。[方法]将黄芪、蒲公英等中草药分别以配伍形式加入艾维因肉仔鸡基础日粮,测定对其生长保健性能的变化情况。[结果]添加中草药配伍A组(0.8%黄芪,0.4%山楂,0.4%陈皮,0.4%苍术)、中草药配伍B组(1.2%蒲公英,0.8%乌梅,0.8%黄柏,0.4%黄芪)肉仔鸡体重分别提高6.12%(P<0.01)及0.64%(P>0.05);肉仔鸡采食量分别改变-7.95%、9.99%;肉仔鸡料肉比分别改变-14.04%、9.35%,中草药配伍B组替代抗生素添加剂使肉仔鸡成活率和对照组保持相当水平。[结论]黄芪配伍中草药对艾维因肉仔鸡生长性能有较好改善作用;蒲公英配伍中草药则使其生长性能有所下降,但可替代日粮中抗生素添加剂的防病保健作用。
