Abstract Lima beans (Phaseolus Lunatus L.) are underutilized crops with an excellent profile. Processing to flour to enhance the starch and protein content, reducing anti-nutritional components and the same time diversifies their use as ingredients by altering their functional properties. The study aims to characterize nutritional, amino acids, anti-nutritional, pasting and functional properties of Lima bean flour from Indonesia’s cultivated plant. The results showed that the Lima bean flour has a high carbohydrate concentration, moderate protein concentration, and low fat concentration. This flour has a balanced amino acid profile, rich in essential amino acids, highlighting them as a source of good quality protein for the food formulation of protein-enriched. The Lima bean flour contained 10.36 mg/g phytic acid, lower in phenolic content (0.63 mg/g) and concentration of HCN (8.83 mg/kg). The functional properties of the Lima bean flour swelling power, solubility, water absorption capacities, and oil absorption capacities were 6.88 g/g, 18.68%, 1.93 g/g, and 1.56 g/g respectively. Pasting properties of Lima bean flour exhibited peak, breakdown, final, and setback viscosity in 1172 cP, 83 cP, 2377 cP, 1288 cP respectively, and temperature pasting was high in 870C. The study may provide useful information to consumers and food manufacturers that Lima bean flour is significant potential used to enhance the nutritional value of cereal-based foods.

Jack bean as a source of vegetable protein had not been popular. Seed germination had been known to improve its nutritional quality, especially protein and amino acid profile. This study determined the effect of germination on the color, beany flavor, protein content, functional properties, and amino acid profile of jack bean flour. A complete randomized design was used for this experiment. Germination was carried out for 0, 24, 48, and 72 hours. The seed (control) and germinated jack bean flours were analyzed for oil absorption, water absorption, emulsifying and foaming capacities, as well as the soluble protein content to determine the best germination time. Furthermore, the amino acid profile of the jack bean flour produced from the best germination time was analyzed. The results of this study indicated that the total and soluble protein of the seed and germinated jack bean seeds for 0, 24, 48, 60, and 72 hours were 23.30 and 5.95; 22.61 and 7.61; 21.18 and 10.68; 23.26 and 10.22; 23.98 and 10.81%, respectively. Germination of jack bean improved the functional properties. A germination time of 72 hours increased the oil capacity, water absorption capacity, foaming capacity and decreased the emulsion capacity significantly. The hydrophilic and hydrophobic amino acids of the germinated jack bean flour increased to 3.21 and 2.12% of the seed flour, respectively. The increase of the foaming capacity was related to the increase in hydrophobic amino acids of germinated jack bean flour compared to seed flours, that were glycine 1.23 and 1.01; alanine 1.29 and 1.01; valine 1.16 and 1.00; leucine 1.84 and 1.09%, respectively. Germination of jack bean for 72 hours increased significantly the essential amino acids, namely: leucine, lysine, and valine.

Protein malnutrition and food insecurity represent serious obstructions to sustainable development,poverty reduction and food quality throughout the world. The present study has been designed to evaluatethe Spirulina platensis (SP) as a protein alternative source for the utilization in food products. A proteinisolate was prepared from S. platensis powder through extraction with 0.1N NaOH, precipitation at pH 3,neutralization of the dispersed precipitate to pH 6.8-7.0, and subsequent freeze drying. The S. platensisisolate amino acids compositions revealed that the total essential amino acids contribution was comparativelyhigher in SPI (31.16±1.43 g/100 g) as compared with SP (27.75±1.21 g/100 g). Moreover, oil and waterabsorption capacities, foaming and emulsifying properties, surface hydrophobicity and nitrogen solubilityindex were found better functional properties under laboratory conditions except emulsion properties.Conclusively, SP and its isolates might be used in various food products to curtail protein energy malnutrition.

The functional properties of protein isolate and major protein fractions prepared from Changbai Mountain pine nuts were investigated. Albumin, globulin, glutelin, and protein isolates were obtained after the Osborne method and alkaline dissolution and acid precipitation, and protein contents of the fractions are 48.02%, 81.93%, 83.02%, and 89.69%, respectively. For the sulfhydryl contents, albumin is the highest, and glutelin is the lowest. In a disulphide bond, the protein isolate content is the highest with a value of 28.74 μmol/g, and the glutelin content is the lowest with the value of 13.46 μmol/g. For the four kinds of proteins, the essential amino acids in percentage of total amino acids are 31.13%, 34.22%, 30.30%, and 34.54%, respectively. The pH dependent protein solubility profile reveals that the minimum solubility is at pH 5.0, which corresponds to the isoelectric point. Protein isolate has the minimum water absorption capacity with a value of 0.59 ml/g. On the other hand, albumin has the minimum oil absorption capacity with a value of 2.11 ml/g. The emulsifying activity and stability and the foaming activity and stability increased with increasing concentration of four kinds of proteins. SDS-PAGE results showed that these four kinds of proteins have different molecules.

The aim of the work was to optimize the process of obtaining multicomponent protein compositions with high biological value and higher functional properties than the original vegetable protein products. Was realized studies to obtain biocomposites on the base of pea protein-oat protein and pea protein-rice protein. Developed composites were enriched with all limited amino acids. For each of the essential amino acids, the amino acid score was 100% and higher. Protein products used in these compositions are not in major allergen list, which allows to use these compositions in allergen-free products and specialized nutrition. To determine biosynthesis parameters for compositions from pea protein and various protein concentrates with the use of transglutaminase enzyme, was studied effect of concentration and exposition time on the amount of amino nitrogen released during the reaction. Decreasing of amino nitrogen in the medium indicated the occurrence of a protein synthesis reaction with the formation of new covalent bonds. Were determined optimal parameters of reaction: the hydromodule, the exposure time, the concentration of EP of the preparation, were obtained mathematical models. Studies on the functional properties of composites, the physicochemical properties of the proteins that make up their composition, and structural features will make it possible to determine the uses in the manufacture of food products based on their ability to bind fat, water, form foam, gels, and etc.

AbstractAs part of measures to combat protein shortages in form of meat analogues, extrusion processing conditions for the development of Texturized Vegetable Protein (TVP) from under-utilized sources (Lima bean and African oil bean seed) are analysed. Optimum parameters for processing were established as being: barrel temperature (92.45°C), screw speed (101.48 rpm), feed moisture (59.63%) and African oil bean seed protein concentrates (AOBSPC) of 1%. Concentrations of essential amino-acids were also found to be significant (0.90-7.3%) with a near absence of anti-nutritional factors (0.0022–1.0008) g/kg. Sensory evaluation showed that TVP5 (100% LBPC) compared favourably with the control sample (cooked meat) in overall acceptability. An Acceptable and nutritious meat analogue had been developed.

Functional Features

Dietary fibre has a beneficial effect on human health that is manifested, among other things, in a reduced risk of obesity, diabetes or neoplasms. Its numerous functional properties render it a desirable food additive. The objective of the research study was to assess the nutritional and functional properties of a novel rapeseed protein-fibre concentrate (RPFC) developed by a NapiFeryn BioTech company. The chemical composition, including the amino acid composition, and the functional properties of RPFC were compared with those of the soy fibre (SF) and pea fibre (PF) available on the market; the purpose of the comparison was to evaluate the potential of RPFC as a novel ingredient for use in food applications. The research study showed that RPFC contained significantly more protein than SF and PF. At the same time it was found that the level of total dietary fibre in RPFC was similar to the level of this ingredient in SF. What's more, RPFC was characterized by the highest contents of ash and phytic acid. Based on the analysis results of amino acids it was proved that the level of lysine was the highest in RPFC. The RPFC was characterized by a higher content of essential amino acids than PF and a lower content thereof than SF. RPFC was distinguished by good functional features, such as emulsifying activity, emulsion stability, and water and oil absorption capacity. It was showed that RPFC had suitable features to be used as a functional food ingredient in food products.

The perturbation in plasma free amino acid metabolome has been observed previously in diabetes mellitus, and is associated with insulin resistance as well as the onset of cardiovascular disease in this population. In this study, we investigated, for the first time, changes in the amino acid profile in a group of people with and without type 2 diabetes (T2D) with normal BMI, from Jordan, who were only managed on metformin. Twenty one amino acids were evaluated in plasma samples from 124 people with T2D and 67 healthy controls, matched for age, gender and BMI, using amino acids analyser. Total amino acids, essential amino acids, non-essential amino acids and semi-essential amino acids were similar in T2D compared to healthy controls. Plasma concentrations of four essential amino acids were increased in the presence of T2D (Leucine, p < 0.01, Lysine, p < 0.001, Phenylalanine, p < 0.01, Tryptophan, p < 0.05). On the other hand, in relation to non-essential amino acids, Alanine and Serine were reduced in T2D (p < 0.01, p < 0.001, respectively), whereas Aspartate and Glutamate were increased in T2D compared to healthy controls (p < 0.001, p < 0.01, respectively). A semi-essential amino acid, Cystine, was also increased in T2D compared to healthy controls (p < 0.01). Citrulline, a metabolic indicator amino acid, demonstrated lower plasma concentration in T2D compared to healthy controls (p < 0.01). These amino acids were also correlated with fasting blood glucose and HbA1c (p < 0.05). Glutamate, glycine and arginine were correlated with the duration of metformin treatment (p < 0.05). No amino acid was correlated with lipid profiles. Disturbances in the metabolism of these amino acids are closely implicated in the pathogenesis of T2D and associated cardiovascular disease. Therefore, these perturbed amino acids could be explored as therapeutic targets to improve T2D management and prevent associated cardiovascular complications.
