Processing Methods

In the present study, the effects of fermentation, roasting, boiling, and boiling with potash on the nutritional and anti-nutritional composition of unsprouted mung bean seed was investigated. Mung bean (Vigna radiata), an underutilized bean was subjected to different processing methods such as boiling, boiling with potash, roasting, and fermentation. Chemical properties such as proximate, mineral, amino acid, and anti-nutrient analyses were done. A total of seventeen amino acids were assayed in mung bean subjected to different processing methods. The ordinary boiling method had the most significant (P<0.05) retention in the amino acid content of mung bean seed. The result of the statistical analysis revealed that there was no significant increase (P>0.005) in the glutamic acid content of mung bean subjected to different processing methods. Fermentation slightly increased the protein content from 25.45 to 25.70%, while the roasted sample had the lowest protein content of 22.15%. There was a fluctuation in the mineral content of processed mung bean. Roasting significantly increased the antinutritional (tannin) content from 0.057 to 0.094 mg/g, while saponin was reduced significantly from 35.73 to 6.67 mg/g. This study has shown that mung bean is on average high in protein content which can serve as a good supplement for dietary protein. Moreover, fermentation and boiling methods may better enhance the nutritional composition of mung bean in terms of retention of protein and reduction of antinutritional factors.

Winter Wheat Varieties

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.

Background: Bambara groundnut is an edible legume that is highly nutritious. This study was carried out to find the effect of nitrogen (N) and phosphorus (P) fertilizers on the growth, yield, nodulation, the proximate and nutritional composition of bambara groundnut [Vigna subterranea (L.) Verdc.]. Methods: During the period of 2018, a glasshouse experiment was conducted in a randomized complete block design (RCBD) at Ladang 15, Faculty of Agriculture, Universiti Putra Malaysia. Different rates of N and P fertilizer were used. Kjeldahl method and HPLC, respectively, determined the protein and amino acid content in seed. Result: N and P fertilizer were found to play a dominating role in increasing the vegetative growth and yield of the plant. Plant height (20.65a), pod number (45.75a) and harvest index (41.61a) increased significantly with the application of N30 + P60 kg ha-1. Application of N30P60 kg ha-1 significantly influenced nodulation and nitrogen yield. Protein, fibre, Mg and amino acid content increased with N30P60 kg ha-1. The application of N30P60 mg kg-1 has increased the growth, yield, nodulation, proximate and nutritional composition of bambara groundnut.

Extrusion cooking has beenused as an important technique for the manufacture and modification of widevariety of food products such as expanded snack foods, ready-to-eat cerealswhich are made from foods with high starch and protein. Although starchy foodsare the predominant structure forming agents, their utilization as food hasbeen limited by their poor protein quality and quantity. The supplementationwith legumes improves the essential amino acid content of the food. Bambaragroundnut has balanced amino acid content and can supplement the quality ofamino acids in sorghum. Starch from sorghum flour has been found to beresistant to extrusion. This makes the modification of functional propertiesvery difficult. Malting of the sorghum has been adopted for the modification ofthe starch quality. The nutrient and functional properties of food play majorrole in their application and use as food. This work has studied the effect offeed moisture (20%, 25%, and 30%) and barrel temperature (100o C,110OC and 130o C) on the chemical composition andfunctional properties of sorghum malt and Bambara groundnut blends. From theresults of the analyses, protein content varied from 11.07% to 11.75%. Increasein barrel temperature decreased the protein content while feed moistureincrease favoured the retention of proteins. The expansion index (EI), waterabsorption index (WAI) and effect of quantity of water on swell volume (EQWSV)varied from 1.88 to 3.88, 570% to 660% and 13.7 seconds to 33.4 secondsrespectively. These properties are negatively affected by increase in feedmoisture but they improve with increases in barrel temperature. The values forwater solubility index (WSI), bulk density and Wettability ranged from 2.2% to8.4%, 0.2g/cm3 to o.7g/cm3 and 14.3 seconds to 37.3seconds respectively. The increase in feed moisture has positive influence onthese parameters while temperature increased affected them negatively.

Mudskipper or glodok fish is a unique fish that can crawl and climb mangrove roots with their fins. In Indonesia, this fish is exported to abroad as a source of food. The by-product of this fish is rarely used, which one is their mucus. Protein is a composition of fish mucus which consists of  amino acids. The mucus of fish has the potential as a source of medicine because it’s proven to have antibacterial, antiviral, and antifungal activities. This study aims to determine the protein and amino acid content of fresh meat and mucus extract of mudskipper. Protein content testing was carried out using the titrimetric method, while amino acid content using the UPLC method. In this study, mucus extract has protein content at 1.79%. It’s small than the protein content of fresh meat at 17.7%. The highest essential amino acid in fresh meat and mucus extract of mudskipper was leucine (15% and 0.91%). The highest nonessential amino acid in fresh meat and mucus extract of mudskipper were glutamic acid (26.4% and 1.6%). The limiting amino acid in fresh meat is leucine as 226.9% and lysine as 12.27% in the mucus extract of mudskipper.

A method is described for the microbiological determination of the protein content of biological materials. This method can also be adopted to titrate the concentration of a single amino acid in the protein and has the following advantages: (1) titration can be done without purification and hydrolysis of proteins; (2) the titration graph is a straight line between 25 and 800 μg/ml; (3) protein values agree with those obtained using the Kjeldhal method; and (4) each mutant requiring one amino acid may be used to titrate the concentration of a single amino acid of the protein. The leucine content of various kinds of flour was measured with this system.

Microalgae can be regarded as an alternative and promising ingredient for food fortification or enrichment. Due to their nutritional composition, especially protein-high composition, they considered as a sustainable protein source for food. The aim of this work was to evaluate the Arthrospira platensis (Spirulina) dry biomass which is knowns as the greater protein and amino acid source in blue-green microalga, as innovative ingredient for newly formulated and produced biscuits and chocolates, for baby and children diets. All samples with Spirulina biomass showed significantly higher protein and amino acid content.
