Natural Amino Acids

A meat-free diet and the aging society cause some of the health problems. One of that was the deficiency of some essential amino acid in the diets. Riceberry has recently been developed in Thailand. This new variety of colored rice has a dark purple seed coat containing anthocyanin which acts as an antioxidant. Similar to normal rice, riceberry lacks lysine which plays an important role in maintaining body systems through hormone release and muscle mass maintenance. To enrich ready-to-eat rice products, red bean was added as a natural amino acid source. This formulated product had higher protein and ash content, while energy, fat and carbohydrate content were not different from the control. The essential amino acid profile of the product was complete and product shelf life was 6 months with an unchanged texture. Anthocyanin and antioxidant capacity of the product decreased with storage time. This product suited a wide range of consumers and was convenient for modern lifestyles that demand healthy, ready-to-eat foodstuffs.

The nutrient composition of dried red seaweed Gracilaria gracilis collected from Barru waters, South Sulawesi including proximate, dietary fiber, minerals, fatty acid and amino acid profile has been investigated. The objective of this study was to evaluate the various nutritional parameters of G. gracilis for utilization in human nutrition. Results show that the content of moisture (19.045), protein (10.86%), ash (6.78%), fat (0.18%), carbohydrate (63.13%) and dietary fiber (27.48%) basis on the dry weight. The content of calcium (429.11 mg.100 g-1), sodium (290.89 mg.100 g-1), phosphor (57.01 mg.100 g-1), iron (15.20 mg.100 g-1) and potassium (1380.42 mg.100 g-1). Leucine was the major essential amino acid found to be 9374.22 mg.kg-1, while glutamic acid was the major non-essential amino acid found to be 10848.98 mg.kg-1. Palmitic acid was the major saturated fatty acid found to be 0.08%, while oleic acid was the major unsaturated fatty acid found to be 0.05%. The nutrient composition of G. gracilis was discussed in this study and suggested that the seaweed species have potentially be used as raw material or ingredient of a healthy food for human.

The objective of this study was to evaluate the quality of meat protein of Dormitator latifrons for humans based on its Protein Digestibility Corrected Amino Acid Score (PDCAAS). Wild and cultured specimens were evaluated for amino acid content using HPLC equipment. The calculation of PDCAAS was performed as follows: milligrams of essential amino acid in 1 g of test protein per milligram of the same amino acid in 1 g of reference protein per true digestibility. To evaluate the protein of D. latifrons in relation to that of other fish, PDCAAS was calculated from the proteins of eight fish usually used in human nutrition. D. latifrons has a good essential amino acid profile, providing the same nutritional quality as those of other fish. Although the meat of wild D. latifrons contributes only 73% of human lysine requirements, it can be complemented with other lysine sources.

The study aimed at evaluating the amino acid profile, fatty acid profile, anti-nutritional factors, functional properties and in-vitro antioxidant activities of Cucurbita maxima and Cucurbita mixta fruit pulps and seeds. Freshly harvested Cucurbita mixta and Cucurbita maxima fruit were processed into flour as; Pa: Cucurbita maxima pulp flour, Pi: Cucurbita mixta pulp flour, Sa: Cucurbita maxima seed flour and Si: Cucurbita mixta seed flour and were evaluated for amino acid profile, fatty acid profile, anti-nutritional factors, functional properties and in-vitro antioxidant activities. Triplicate data were analysed and means were separated using New Duncan Multiple Range Test (NDMRT) at p<0.05. The protein content of the fruit pulps and seeds flour samples were 12.77 g/100 g (Pi), 13.22 g/100 g (Pa), 15.37 g/100 g (Sa) and 16.86 g/100 g (Si). Total essential amino acid was 5.33 mg/100 g of protein (Pa) 6.62 mg/100 g of protein (Pi), 9.85 mg/100 g of protein (Sa) and 14.61 mg/100 g of protein (Si). Total essential amino acid of Pi and Si are significantly higher (p>0.05) than Pa and Sa. Statistically, saturated fatty acid and polyunsaturated fatty acid of the Pi and Si were significantly lower (p<0.05) than Pa and Sa respectively. Antioxidant activities against ABTS* (Pi) is significantly higher (p>0.05) than Pa and with no significant differences (p<0.05) between ABTS values of Si and Sa. While there is a significant difference (p<0.05) between Si and Sa as well as Pi and Pa antioxidant activities against DPPH* respectively. In conclusion, Cucurbita seeds and pulps flour contains high protein content, appreciable amount of essential minerals, lower Na/K molar ratio of less than one and they also exhibit a good free radical scavenging abilities against DPPH*, ABTS* and ability to reduce Fe3+ to Fe2+ with high content of total phenol and flavonoid.
