Shrimp shell composition had determined on dry base for moisture, ash, lipid and protein content were 72, 11, 1, 16% for wet samples and 14.5, 25, 2.06 and 31% for dry samples respectively. Different methods were employed for carotenoids extraction from dried shrimps shell . The first method (T1) used different combinations of organic solvents (Ethanol: petroleum ether, 1:1 V/V) by soxhlet device at 50°C. The second (T2) and Third (T3) methods used separately acid and basic infusion for 48 hours with 0.1N, HCL and 0.1N NaOH respectively. The fourth method (T4) based on sunflower oil extraction . The fifth treatment (T5) included cold extraction with ethanol (100%). The sixth method used solvent combination of Hexane: Acetone (1:1 V:V) . The seventh method used combination of Hexane: Acetone (2:1 V/V). The T6 was adopted as the highest carotenoid yield was obtained and valued 0.08 µg/g with 80% extraction yield as compared to the other of or mentioned methods. Deproteinization to carotenoids were conducted on shrimp samples before extraction and valued 76.5% for wet samples and 58.5% for dry samples. Crud extract had added in different levels of 0.01, 0,2, 0.04. 0.5 and 1% in sesame oil compared to control and BHT 0.02% and samples stored to 30 days at 65°C. Peroxide Value and Thiobarbituric acid were determined for sesame oil samples after every two days storage. The obtain results revealed that the 1% crud extract in sesame oil have the strongest effect as natural antioxidant against oil oxidation to 28 days compared with other group. © 2018 Plant Archives.
