High performance liquid chromatography (HPLC) was used to determine the amino acid and fatty acid content of Morinda citrifolia (Noni). The amino acid content both free and total was determined at the mature green, mature ripe and fermented stage of the fruit. Most of the essential amino acids were detected as free amino acids (unhydrolysed sample) at the various stages of ripening, with threonine showing the highest value (3.95±0.81 mg/100g) at the fermented stage and histidine showing the lowest value (0.05±0.02 mg/100g) at the mature green stage. The essential amino acids with the exception of tryptophan (destroyed by acid hydrolysis) were also detected as total amino acids (hydrolyzed sample) albeit at much higher concentrations. Leucine showed the highest value (94.21±18.85 mg/100g) at the mature ripe stage, whereas methionine the lowest value (2.80±1.02 mg/100g) at the mature green stage. The fatty acid content of the Noni fruit  was also determined at the green, ripe and fermented stages of ripening; with the short chain caprylic acid (80.69±3.09 mg/100g) showing the highest value at the ripe stage. Significantly the essential fatty acids linolenic (8.60±0.21 mg/100g) and linoleic (50.57±0.72 mg/100g) were highest at the green stage. Also present in significant quantities were palmitic acid (44.27±0.35 mg/100g) and stearic acid (4.78±0.45 mg/100g) at the green stage. The amount of fatty acids decreased significantly at the fermented stage. Of the fatty acids detected at the fermented stage 79% of them were below 1.00 mg/100g fresh weight of the fruit.

ABSTRACT Samples of eggs, newly hatched larvae (NHL), and larvae at the end of the lecithotrophic period (eight days after hatching) (LPL) of Lophiosilurus alexandri were collected to determine the amino acid and fatty acid profiles. Crude protein did not change throughout initial development and the concentration of lipids was highest in NHL. The content of the indispensable amino acids (IAA) isoleucine, leucine, and valine decreased in LPL, while in eggs and NHL they remained high and similar in value. The dispensable amino acids (DAA), such as aspartic acid, tyrosine, and glycine, increased in LPL, while alanine decreased. The percentage of neutral lipids increased in LPL. The saturated fatty acid content decreased during ontogeny, while monounsaturated fatty acids decreased only in LPL. The polyunsaturated fatty acid content was highest in LP. Polar fatty acids were found in higher percentages in eggs and NHL, but lower in LPL. Saturated fatty acid content decreased during ontogenetic development, while that of monounsaturated fatty acids decreased only in LPL. Polyunsaturated fatty acid content was highest in LPL. Protein content was maintained during ontogenetic development, while amino acid classes experienced changes. Lophiosilurus alexandri preferentially uses saturated and monosaturated fatty acids as an energy source during its early development.

Green peel avocado is a fruit with high nutritional value, rich in lipids, proteins, sugars, vitamins, and minerals. The aim of this study was to determine the change in fatty acid and amino acid content of green peel avocados harvested at 200, 210 and 220 days in order to select the appropriate harvest time, serving for efficient preservation and processing. The results of the study showed that 9 fatty acids were identified at the time of harvesting at 200 days, 10 fatty acids at the time of harvesting at 210, and 220 days of green peel avocado. Compared with two harvest times as 210, and 220 days since fruiting, the fatty acid content of green peel avocado did not differ so much. By using the HPLC method, 13 amino acids, 14 amino acids, and 15 amino acids were identified at 200, 210, and 220 days after fruiting, respectively. Glycine, alanine, lysine, and phenylalanine were intended to increase in the developmental stages of green peel avocado, whereas the other amino acids did not change much. Therefore, based on the change in fatty acid and amino acid content, green peel avocado farmers in Son La province should choose the time of harvest from 210 to 220 days from fruiting to be suitable for preservation and processing. If harvesting green peels avocados at more than 220 days after fruiting, it will make the dried fruit and spongy, and affect flowering, fruit set, and yield in the next fruit crop.

Abstract Sewage sludge was subjected to hydrothermal fueling (HTF) (330 °C for 40 min), obtaining hydrochar at 13.5 MJ kg−1. The higher heating value (HHV) of the raw sludge was related to its fatty acid content. The results showed that although the higher heating value (HHV) of the raw sludge was related to its fatty acid content, with the intensification of HTF, the increase in aliphatic/cyclic amino acids determined the production of HHV in the hydrochar. In order to increase the content of fatty acids and amino acids, the sludge was fermented. However, the Bacteroidetes consumed the organic matter too early, which was detrimental to the production of HHV. Therefore, appropriate sludge fermentation is recommended to restrict excessive Bacteroidetes proliferation, decompose lipids to saturated fatty acids, and convert proteins to aliphatic/cyclic amino acids to increase the efficiency of converting sludge to fuel.

The purpose of this study was designed to investigate the amino acid and fatty acid composition of taro leaf and corm samples. An UHPLC and GC-FID method was used for the determination of amino acids and fatty acid composition, respectively. Taro leaf was processed as a powder and pre-curd concentrates while the corm was pre-gelatinized with and without peel prior to the analysis. The amino acid and fatty acid composition (%) of the analyzed samples were quantified with their relative area comparing with respective standards. In the present study, the leaf and corm of taro contained the three essential amino acids leucine, lysine and methionine. For the study, the calculated amino acid values were low in corm samples, but amino acid composition was higher in the leaf samples. Concerning fatty acids, the dominant fatty acid in the leaf and corm was oleic acid (C18:1, n-9) which ranged from 140.697 ± 0.054 to 216.775 ± 0.043 and 101.932 ± 0.023 to 101.950 ± 0. 04 mg/100 g, respectively. In the study, the fatty acid compositions in leaf were higher than the corm. This means that taro leaf would be considered as a good source of essential amino acid and fatty acid than the corm. Finally, from the proportion (mg/100 g) of saturated, monounsaturated and polyunsaturated fatty acids, the unsaturated fatty acids were the predominant fatty acids observed. The presence of high levels of unsaturated fatty acids in the entire investigation of our study taro is nutritionally rich.

The study was aimed to analyze the mineral content, amino acid and fatty acid composition of Polistes olivaceus larvae consumed by different aboriginal tribes of North East India. Although the edible insect larvae has high market value in Assam and adjoining states of North East India, the nutritional analysis on it has not been done till now. Mineral elements including potassium, sodium, calcium, magnesium, phosphorus, zinc, iron and copper were detected by Atomic Absorption Spectroscopy. Amino acid composition and fatty acid profile were analysed by high performance liquid chromatography and gas chromatography mass spectrometry respectively to ascertain its potentiality to be included in food based strategies concerning human health. Iron and copper were the most abundant minerals and potassium, sodium and phosphorus were present in substantial amounts. Nineteen amino acids including all essential amino acids (43.87%) except isoleucine were detected in the sample. All essential amino acids satisfied the recommended level (score&gt;100) except leucine with a chemical score of 98%. The level of unsaturated fatty acids was 53.21% while the saturated fatty acids constituted 47.02% of the total fatty acids signifying its potentiality in nutrition and health. Presence of linolenic acid as the main constituent of polyunsaturated fatty acids greatly signifies its importance in human nutrition. Thus, Polistes olivaceus larvae may be exploited to provide high-quality diets among populations plagued by iron deficiency as well as poor supply of dietary proteins and polyunsaturated fatty acids.
