Variation in tuber proximate composition, sugars, fatty acids and amino acids of eight Oromo dinich ( Plectranthus edulis ) landraces experimentally grown in Ethiopia

An attempt was made to study the nutrient profile of traditionally sun-dried Acetes with respect to its proximate composition, amino acids, fatty acids, minerals and heavy metals. From the results, it was found that dried Acetes contained 19.00±0.70% moisture, 48.29 ± 0.64% crude protein, 16.05±0.52% ash and 3.62±0.09% crude fat. Biopolymer content in dried Acetes showed 10% chitin. Amino acid profile of dried Acetes confirmed that it could serve as a significant source of essential amino acids. Fatty acid profile revealed 9, 12-otadecadieonic acid (17.08%), docosahexaenoic acid (DHA) (15.69%), eicosapentaenoic acid (EPA) (13.45%) and docosanoic acid (11.75%) as the major fatty acids. Mineral profiling indicated the presence of P, Ca, K, Mg, Na and Fe. Heavy metal analysis indicated the presence of Cd, Cu, Pb and Zn. However, harmful metals like cadmium and lead were found to be low. From microbiological quality analysis of dried Acetes, the total plate count and faecal coliforms count were found to be 4.1 x 103 cfu g-1 and 35 MPN per100 ml, respectively while Staphylococcus aureus colonies were not detected. Results of the study indicated that dried Acetes was not processed properly and hygienically as revealed by its content of high moisture and faecal coliforms, respectively. Further, based on proximate composition, amino acids, fatty acids and mineral profile, it can be concluded that dried Acetes can be a good source of health beneficial nutrients.

The nutritional composition and antinutritional factors of Rhynchosia bracteata Benth. underexploited tribal pulses locally known as Advi Chekkudu in Telugu, used as food by local tribals in the Rollapenta forest, Kurnool district, Nallamalais of Andhra Pradesh. The mature seed samples were analysed for proximate composition, total (true) seed protein fractions, amino acid composition, fatty acids profile, mineral and antinutritional factors. The investigated seed samples contained higher amount of crude protein, crude fat, ash and nitrogen free extractives constitute 20.18, 6.16, 6.12 and 61.31 % respectively. The calorific value of the seed weight 100 g dry seed material was 366.86 K.cal. The essential amino acids, leucine, tyrosine and phenylalanine, were present in relatively large quantities. The fatty acid profiles revealed that the seed lipids contained higher concentrations of palmitic and linoleic acids. The seeds are rich in magnesium, iron potassium and phosphorous. Antinutritional factors such as total free phenols, (3.76 %) tannins (0.29%), L -DOPA (0.51%), hydrogen cyanide (0.066%) and phytic acid (0.18%) are present in variable quantities. This paper presents the chemical composition and nutritional potential of Rhynchosia bracteata seeds with regard to its suitability as a regular component in human diet. Key words.

Fish Weight

The nutritional characteristics such as proximate composition, amino acids, and fatty acids properties of fish depend on the size of fish. Determination of the nutritional parameters of Thai pangus muscle depending on five different sizes, viz., 0.5 kg, 1.0 kg, 1.5 kg, 2.0 kg, and 2.5 kg showed that the moisture content was decreased whereas the protein content was increased with the increment of fish weight. The protein content was the highest 16.60% in 2.5 kg size fish and the lowest content 14.75% was in 0.5 kg size fish. The lipid content was found to increase significantly (P≤0.05) with the increment of fish weight. There were eight essential and nine non-essential amino acids available and the contents were found to increase with the increment of fish weight. The content of essential amino acids was the highest (14.43 g/100 g fish muscle) in 2.5 kg size fish while the lowest (7.79 g/100 g fish muscle) in 0.5 kg size fish. Total 13 fatty acids were detected in fish oil among which oleic acid content was the highest (44.55% to 47.10%) followed by palmitic acid (25.78% to 36.39%), however, the ω-3 polyunsaturated fatty acids contentwere very poor. The saturated fatty acids content were found to increase whereas the polyunsaturated fatty acids content were found to decrease with increasing the size of fish. So, the findings of this present study reveal that the muscles of Thai Pangus fish are considered as highly nutritive and healthy.

Rainbow Trout Oncorhynchus Mykiss

In order to evaluate the application potential of rainbow trout (Oncorhynchus mykiss) heads and skipjack tuna (Katsuwonus pelamis) heads; proximate composition, amino acids, fatty acids, carnosine, and anserine contents were analyzed in this study. Rainbow trout heads showed significantly higher protein (29.31 g/100 g FW, FW is abbreviation of fresh weight) and lipid (6.03 g/100 g FW) contents than skipjack tuna heads (18.47 g/100 g FW protein and 4.83 g/100 g FW lipid) (p < 0.05). Rainbow trout heads and skipjack tuna heads exhibited similar amino acid composition. Essential amino acids constituted more than 40% of total amino acids in both rainbow trout head and skipjack tuna head. The fatty acid profile was different between rainbow trout heads and skipjack tuna heads. Rainbow trout heads mainly contained 38.64% polyunsaturated fatty acids (PUFAs) and 38.57% monounsaturated fatty acids (MUFAs), whereas skipjack tuna heads mainly contained 54.46% saturated fatty acids (SFAs). Skipjack tuna heads contained 4563 mg/kg FW anserine and 1761 mg/kg FW carnosine, which were both significantly higher than those of rainbow trout heads (p < 0.05). These results demonstrate that both rainbow trout heads and skipjack tuna heads may be used as materials for recycling high-quality protein. Meanwhile, rainbow trout heads can be used to extract oil with high contents of unsaturated fatty acids, while skipjack tuna heads may be a source for obtaining carnosine and anserine.
