N S Bassily, K G Mekhael, N H Elbanna, A K Said

The protein quality of two common Egyptian meals namely lentils and "Koshari" was evaluated on rats by utilizing the net protein ratio (NPR), the relative protein value (RPV) and the serum urea content methods. Casein was used as a reference protein. The macro nutrient contents of the two meals are almost similar. The NPR is higher with low dietary protein level. The estimated RNV of the "Koshari" was higher than that of lentils. Lower serum urea levels were found with the "Koshari" than with lentils meal indicating its better protein quality. This is most probably due to the effect of amino acid supplementation of cereals and legumes. Results obtained are in favour of utilizing the serum urea content method as a simple and reliable one for evaluating protein quality since a negative relationship exists between blood urea content and the biological value of dietary protein. Its validity in estimating dietary protein quality in man need to be investigated.

采用净蛋白比(NPR)法、相对蛋白值(RPV)法和血清尿素含量法，对两种埃及常见食物扁豆和“沙里”的蛋白质质量进行了评价。酪蛋白作为参比蛋白。两餐的宏观营养素含量几乎相似。饲粮蛋白质水平越低，猪的NPR越高。“Koshari”的RNV估计高于扁豆。与小扁豆粉相比，“Koshari”的血清尿素水平较低，表明其蛋白质质量更好。这很可能是由于谷物和豆类补充氨基酸的影响。结果表明，血清尿素含量法与饲粮蛋白质的生物学价值呈负相关，可作为一种简便、可靠的蛋白质品质评价方法。其在评价人体膳食蛋白质质量方面的有效性有待进一步研究。

70 fat samples collected from Rostock men and women, aged between 20 and 90 years, were analysed by gas chromatography for total DDT and polychlorinated biphenyls (PCB). It was found that the mean value for DDT and also that for PCB increased with the increase in age, the mean values for all the subjects being 4.0 +/- 0.5 mg/kg (PCB). There were no statistically significant differences among the residue values found in men and women.

The membrane-bound leucine arylamidase of the microvilli of the rat small intestine was solubilized by Triton X-100 and purified by gel and ion-exchange chromatography. As compared to the mucosa homogenate, the purification factor was 135. The leucine arylamidase and aminotripeptidase of the microvilli cannot be separated by chromatography. The cytosomal portion of the aminopeptidase is devoid of leucine arylamidase activity.

L Telegdy Kováts, E Berndorfer-Kraszner

Certain aspects of the present state of vitamin research are treated with special regard to a modern interpretation of the concept of vitamin and to questions concerning the utilization of recent findings by the food industry and other sciences. A classification of vitamins according to their solubility and functional properties is discussed. Recent findings on the relationships between tocopherols and tocotrienols and on bioquinones are dealt with. Furthermore, the significance of some vitamin-like substances (such as choline, S-methylmethionine and pangamic acid) and their biochemical importance for the animal and the human organism are considered.

对维生素研究现状的某些方面，我们将特别考虑对维生素概念的现代解释，以及有关食品工业和其他科学利用最新发现的问题。根据维生素的溶解度和功能性质对其进行了分类。对生育酚和生育三烯醇之间的关系以及生物醌的最新发现进行了讨论。此外，还讨论了一些类维生素物质(如胆碱、s -甲基蛋氨酸和pangamic acid)的意义及其对动物和人体有机体的生化重要性。

Ochratoxin A was to be evenly distributed in kernels of different lots of wheat and barley grain. Dry cleaning and wet cleaning did not eliminate ochratoxin from grain. After milling the level of ochratoxin in flour was similar to its concentration in bran. In pearl barley concentration of ochratoxin A stated only 10-30% of initial concentration in barley grain. Detoxification is necessary for the whole kernel, because processing did not remove ochratoxin A effectively.

赭曲霉毒素A在不同批次小麦和大麦籽粒中分布均匀。干法清洗和湿法清洗均不能消除谷物中的赭曲霉毒素。碾磨后面粉中赭曲霉毒素的含量与麸皮中赭曲霉毒素的含量相近。珍珠大麦中赭曲霉毒素A的浓度仅为大麦籽粒初始浓度的10-30%。对整个果仁进行解毒是必要的，因为加工并没有有效地去除赭曲霉毒素A。
