Objective: To determine the protein quality, especially the amino acid content of 8 tropical fruits both raw and boiled samples. Eight different tropical fruits were used in the study (Apricot, Jamun, Dragonfruit, Pomegranate, Mangustan, Litchi, Jackfruit, and Kiwi.Methods: Ninhydrin method was used for the estimation of the concentration of amino acids present in the above fruits. Raw and boiled fruits were used for the study.Results: Both raw and boiled forms which showed thats Jamun and Mangustan contained highest concentration amino acids whereas apricot shows the lowest concentration of amino acids except in Jamun which showed higher values in the raw fruit whereas in others the boiled samples showed higher values.Conclusion: It was evident that tropical fruits have a good balance of the essential amino acids (both raw and boiled fomr) which provide significant sources of protein in our diet.

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.

Essential Amino Acid Content

Infant formulas, designed to provide similar nutritional composition and performance to human milk, are recommended when breastfeeding is not enough to provide for the nutritional needs of children under 12 months of age. In this context, the present study aimed to assess the protein quality and essential amino acid content of both starting (phase 1) and follow-up (phase 2) formulas from different manufacturers. The chemical amino acid score and protein digestibility corrected by the amino acid score were calculated. The determined protein contents in most formulas were above the maximum limit recommended by FAO and WHO guidelines and at odds with the protein contents declared in the label. All infant formulas contained lactoferrin (0.06 to 0.44 g·100 g−1) and α-lactalbumin (0.02 to 1.34 g·100 g−1) below recommended concentrations, whereas ĸ-casein (8.28 to 12.91 g·100 g−1), α-casein (0.70 to 2.28 g·100 g−1) and β-lactoglobulin (1.32 to 4.19 g·100 g−1) were detected above recommended concentrations. Essential amino acid quantification indicated that threonine, leucine and phenylalanine were the most abundant amino acids found in the investigated infant formulas. In conclusion, infant formulas are still unconforming to nutritional breast milk quality and must be improved in order to follow current global health authority guidelines.
