Ocimum tenuiflorum L., commonly known as ruku in Malaysia, is usually cultivated as a garden ornamental plant because of its small purplish and some yellowish flower. Additionally, the young leaves of O. tenuiflorum L. are used to make Nasi Ulam. In this study, we investigated the nutritional values of O. tenuiflorum leaves and stems to find a rich source of essential nutrients needed in daily diet. High pressure liquid chromatography (HPLC) and gas chromatography/mass spectrophotometer (GC/MS) methods were used to measure the amino acid and fatty acid content of leaves and stems of O. tenuiflorum L. The result of antinutritional compositions of the leaves and stems displayed as a safe range of compounds that were effective to increase absorption of nutritional compound by body cells. The result of fatty acid profile showed that the butanoic acid as the highest amount of fatty acid content in stems and leave compared to other fatty acid compositions. The result of amino acids profile indicated that αaminobutyric acid and cysteine (non-essential amino acid) showed the highest and the lowest amount of amino acid content in stem and leaves consequently. Vitamin E and C showed the high and lowest amount of vitamins content in the leave and stem, respectively. In conclusion, the result of antinutritional and nutritional contents of O. tenuiflorum L. leaves and stems clearly indicated that the antinutritional compounds were in the safe range. The amount and nutritional content of the leaves and stem proved that this plant a good source to improve our body health system.

The purpose of this study was to figure out catfish meat's chemical composition, mineral content, amino acid composition, and fatty acid profile. Moisture, protein, lipid, and ash content were measured at 71.30%, 19.03%, 8.10%, and 1.5%, respectively. Catfish meat had higher levels of calcium, phosphorus, and iron, with 304.82, 279.45 and 17.03 mg/100 g, respectively. The essential amino acid content was 41.81 g/100g protein. Oleic, linoleic, and palmitic acids were the most common fatty acids present in catfish meat. Oleic acid made up more than a third of the fatty acid content in catfish meat. Because of its high oleic acid content, catfish meat should be considered because it has been linked to a lower risk of cardiovascular disease.

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.

The non-thermal high-pressure processing (HPP) technique has been used to increase the shelf life of food without compromising their nutritional and sensory qualities. This study aims to explore the potential application of HPP on New Zealand lamb meat. In this study, the effect of HPP, at different pressure treatments (200–600 MPa) on eight different lamb meat cuts in terms of lipid oxidation, fatty acid and free amino acid content were investigated. In general treatments between 400 and 600 MPa resulted in higher oxidation values in eye of loin, flat, heel, and tenderloin cuts. Saturated and monounsaturated fatty acid content were significantly lower with HPP treatment of almost all cuts (except rump and heel cuts) at all pressures. Polyunsaturated fatty acid content was significantly lower in HPP-treated inside, knuckle, and tenderloin cuts at 600 MPa compared to control. Nine essential free amino acids (valine, leucine, isoleucine, methionine, phenylalanine, lysine, histidine, tyrosine and tryptophan), and eight non-essential free amino acids (alanine, glycine, threonine, serine, proline, aspartic acid, glutamic acids and ornithine) were identified in the lamb cuts. HPP increased the total free amino acid composition significantly compared to control at all pressures for almost all cuts except the inside and eye of loin cuts. This study suggests that higher pressure treatments (i.e., 400 and 600 MPa) resulted in higher TBARS oxidation levels. Additionally, significant decreases in saturated and monounsaturated fatty acids and increase free amino acid content were observed in the majority of HPP-treated samples compared to control.

The coastal communities of Kendari believe that sea worm as traditional drug can cure a wound, because some chemical compounds that exist in sea worms are suspected to have the compound. The aims of this study were to determine chemical compound, amino acid, fatty acid content, and mineral of flesh<br />sea worm (Siphonosoma australe-australe) from Toronipa Aquatic Province Sulawesi Southeast. The higest essential amino acid content on fresh sea worm was arginin  (3.04%), and freeze dry was 5.52%. The higest non-essential amino acid content on fresh sea worm and freeze dry were glutamic acid 6.53% and 8.53% for <br />product resulted by freeze dry. The higest saturated attyacid (SF) content of fresh sea worm and freeze dry were palmatic acid (1.96% and 2.64%). The higest MUFA  fatty acid content of fresh sea worm and  freeze dry were plamitoleat acid 0.31% and 0.27%. The higest poly unsaturated fatty acid (PUFA) of fresh sea worm and freeze dry were were aracidonat 2.80% and oleat acid 1.97%. The higest mineral content of wet sea worm and frezee dry were Natrium 43,700 mg/kg and 127,334 mg/kg.

Coastal waters of Indonesia have considerable biodiversity of sea cucumbers. In the present study the amino acid and fatty acid contents in sea cucumber Stichopus vastus collected from Salemo Island waters Indonesia were determined. Results showed that all essential and non-essential amino acids were found in S. vastus. The major essential amino acid content was arginine (28651.62 mg/Kg). Whereas the major non-essential amino acid content was glycine (60907.24 mg/Kg). The total fatty acids were determined in which finding suggested that saturated fatty acid was more than polyunsaturated fatty acid and monounsaturated fatty acid. The higher saturated fatty acid, polyunsaturated fatty acid and monounsaturated fatty acid were palmitic acid (0.07%), arachidonic acid (0.13%) and palmitoleic acid (0.03%) respectively.
