Three cultivars ofVigna radiata, namely, NM-92, NM-98, and NM-06, were analyzed for their proximate composition. The samples were also tested by HPLC for amino acid content. The data showed that all the varieties had same moisture level. The maximum ash content (4.29%) was present in NM-92, and crude fat (2.26%) was highest in NM-98 while NM-06 contained maximum amount of crude protein. About eighteen types of amino acids were detected in each of the three varieties. Acidic amino acids, that is, aspartic and glutamic acids, were in considerable amount ranged from 13 to 23% followed by leucine, isoleucine, alanine, valine, lysine, phenyl alanine, serine, and arginine which fell in the range of 3–8% of total protein. The maximum amount (13.00 and 22.80%) of aspartic and glutamic acids was present in NM-98. Similarly arginine (6.83%) and serine (5.45%) were also in highest amount in this variety. Leucine (7.46%) was maximum in NM-92 variety. NM-06 contained almost all the amino acids in lesser quantity except for few like threonine, proline, glycine, and alanine. It was concluded from the present study that varieties were of different nutritional value and HPLC was a sensitive method for amino acids determination. Antioxidant activities of all three varieties were also assayed and showed significant results.

The date palm (Phoenix dactylifera L.) is one of mankind’s oldest cultivated plants. The fruit of the date palm is an important crop of the hot arid and semi-arid regions of the world. It has always played a genuine economic and social part in the lives of the people of these areas. The present objective in examining the amino acid content of different varieties of date palm fruits from Middle-East region; is to determine whether its protein could effectively supplement the nutritional value and it is also aimed in finding which variety is rich in number of amino acids. The phytochemical screening revealed the presence of eight essential amino acids and five non-essential amino acids in the date fruits. Among all the date fruit varieties taken as samples for the study, Dabbas cultivar of United Arab Emirates found to exhibit eight types of amino acids which includes five as non-essential ones. Total of thirteen amino acids were detected in the seven date cultivars. Determination of amino acid can serve as a guide to the possible nutritional value.

1. The amounts of available cystine and tyrosine in the protein of different animal tissues showed a close correlation with the level of hydroxyproline, and may be estimated from hydroxyproline values by regression equations.2. Estimates of ‘chemical score’ have been calculated from the content of hydroxyproline determined in a series of samples for which net protein utilization (NPU) for rats had also been determined. Chemical scores calculated as percentages of the total ‘essential+semiessential’ amino acid content of each material correlated closely with NPU, whereas scores calculated as percentages of total amino acids did not. ‘Methionine+cystine’ were calculated to be first limiting amino acids in every sample.

We analysed the crude protein content, amino acid content, amino acid composition of four forage and milling III. quality winter wheat varieties (Magor, Hunor, Róna and Kondor) from their samples from five following years (2003, 2004, 2005, 2006, 2007). We found that quantity of essential and non-essential amino acids rose with increase in crude protein content. On examination of protein amino acid composition in relation to crude protein content we found that the crude protein content increased the quantities of the non-essential amino acids also rose, while those of the essential amino acids decreased as the lysine, the limiting amino acid of wheat. We also established that, as crude protein content increased, the biological value of the protein decreased.

To decrease the toxic effects of xenobiotics on healthy workers in healthful and dietary meals, it’s important to consider not only the proper diet intake of macro- and micronutrients, but protein quality in terms of essential amino acids. A study was conducted to evaluate nutritional value and amino acids content in the industrial workers diets of two metallurgical enterprises by calculation and laboratory methods. We found that set of healthful and dietary meals at the calculation stage do not comply with regulatory requirements for fats and carbohydrates by 34 and 16 percent, respectively. According to laboratory tests, from 57 to 68 percent of sets of healthful and dietary meals do not comply with regulatory requirements for proteins, fats and carbohydrates. The discrepancy in the data on the amount of determined nutrients between the calculated and laboratory methods may be due to calculation errors, shortage and quality of raw materials, as well as a limitation of methods for determining fat and carbohydrates. With a set of healthful and dietary meals workers can satisfy the almost daily requirement for the corresponding energy expenditures for some amino acids, however, the required amount of these amino acids in workers in contact with heavy metals has not been established. It has also been found that in diets of healthful and dietary meals, the ratio of tryptophan / lysine / methionine + cystine is violated towards an excess of tryptophan, whose deamination products are highly toxic. It is necessary to continue further investigation of ready-made diets of healthful and dietary meals for nutritional value and amino acid content in order to identify factors affecting the discrepancy within research results between calculation and laboratory methods, as well as establish adequate norms for amino acids intake in workers exposed to toxic substances.

AbstractHoney production in Africa is considered an integral part of folk medicine and provides an opportunity for poor rural communities to increase their economic sustainability. In this review, we provide and discuss the data available on the positive nutritional value and health properties of honey harvested from Africa. Besides sugar, honey contains protein and amino acids, with proline which is about 50% of the total amino acids, vitamins, enzymes, some minerals (Na, K, Mg, Ca, Zn, Cu, Mn, Fe, P, S), trace elements (Mn, Ni, Li, F, I, Cl, Sr, Co) and polyphenol compounds. The paper reviewed studies on the use of African honey with anti-inflammatory, antioxidant, antibacterial, antifungal, anti-breast cancer, antidiabetic and antimycotic properties and also its positive effects on infertility (asthenozoospermia), febrile neutropenia and diabetic foot ulcers.

The aim of this study was to evaluate the possible effects of maize replacement in feeding rations on the amino acid content in cows´ milk. Cows were fed total mix ration based on the maize, clover silage and hay. There was a difference in the concentrate of the feeding ration. The first group (fed maize) was the control group, another two groups were experimental, one fed wheat and second fed triticale. During six weeks, totally 26 milk samples were taken from dairy cows of Czech Pied breed. Feed groups were preferably balanced in terms of milk yield, stage and number of lactations. The samples of feedstuffs as well as milk were modified for the analysis using acidic and oxidative hydrolyses. The analysis of amino acids content and composition of the sample hydrolysates was performed chromatographically by an AAA 400 analyzer, using Na-citrate buffers and ninhydrin detection. Total nitrogen content was determined according to Kjehldahl and the crude protein of the samples was determined by conversion from the nitrogen content multiplied by appropriate factor. The high content of crude protein in wheat did not influenced composition of milk from dairy cows fed this type of feedstuff. With respect to resulting amino acid content and composition of milk samples, none of the tested grains can be re­com­men­ded as a full-value maize replacement. Each feedstuff is an abundant source of several and ty­pi­cal amino acids in milk. However, triticale (cultivar Kitaro) seems to be acceptable replacement of maize owing to better crude protein efficiency, composition and health indicators of milk quality.

Setaria Sphacelata

Setaria sphacelata is a high and most prevalent tropical grass, while Cleome gynandra is a tropical annual herb which commonly used as vegetables in Africa and Asia. Both plant samples were found to be high in nutritive value especially in protein and very appetizing in ruminants. The main objectives of the study were to measure and compare the nutritional composition of Setaria sphacelata and Cleome gynandra as a function of their nutritional value for ruminants. The two plant samples were collected near the Tembila area, Besut Terengganu. The samples were dried in a furnace below 60 - 70 ˚C and crushed prior to further analysis using proximate analysis. Proximate analysis was used to measure values for moisture, dry matter (DM), ash, crude protein (CP), crude fibre (CF), ether extract (EF) and nitrogen-free extract (NFE). The result of this analysis shows that Cleome gynandra had much higher crude protein (CP) (p < 0.05) at 36.86% and ether extract (EF) at 5.50%. Crude protein (CP) is one of the most essential nutrients that ruminants need. Therefore, this study found that Cleome gynandra contains a higher nutritional value in terms of crude protein (CP) than Setaria sphacelate, which can be used as a feed for ruminants.
