Abstract Florunner peanut seeds contained five trypsin isoinhibitors. Amino acid profiles of the trypsin inhibitors fraction showed high levels of aspartic acid, half-cystine and serine and low levels of histidine and tyrosine. The molecular weight of the inhibitor was 8.3 KDa. The presence of multiforms of this inhibitor, its low molecular weight and the high amount of half-cystine indicate that peanut trypsin inhibitor is of the Bowman-Birk type.

Quinoa (Chenopodium quinoa Wild) is a plant that recently has been successfully grown in Iraq, providing seeds rich in nutrients and bioactive compounds. The distribution of metal composition and amino acid value in the quinoa seed was determined using the X-Ray Fluorescence technique. The present study aimed at the characterization of chemical composition, nutritional value, and amino acid profiles of quinoa seed cultivated in Iraq. Moisture, ash, gross fat, gross protein, gross fiber and carbohydrate contents concerning quinoa seeds were ranged from 9.45 ± 0.22 %, 2.13 ± 0.045 %, 6.4 ± 0.043%, 6.4 ± 0.873 %،3.8 ± 0.044 % to1.67+68.1 % respectively. The current study was undertaken to Detection of active compounds in quinoa seed extract including, alkaline, flavonoids, phenols, glycosides, resins, and tannins, where all the findings were positive. It could be concluded that quinoa seed, cultivated in Iraq are a good source of essential nutrients such as minerals, essential amino acids.

White particulates were occasionally observed in the brine of indigenous fermented foods, including sufu, salt-preserved shell fish, oyster, finfish, and pork. Products with and without visible particulates were collected and brines were analyzed. The pH values, salinity, and alcohol content in brines containing particulates were slightly higher than those not containing particulates. Differences of amino acid profiles were not significant. When particulates were isolated and subjected to amino acid analysis, only tyrosine and phenylalanine were present and accounted for 34.82 ± 24.30% and 3.13 ± 2.93% on a dry weight basis, respectively. The particulates consisted largely of hollow particles as observed under scanning electron microscopy. When the particulates were dissolved in 0.4 N HCl, evaporated for crystallization, and examined using stereo microscopy and an X-ray diffractometer, L-tyrosine crystals were observed.
