Using the optimal oil extracted from Sardinella sindensis to produce health moisturizing cream

Abstract

Introduction: The consumption of small fish such as sardines does not have a significant
place in the family's food basket, but they are a very rich source of mineral salts, protein, and
fat, which until now are the most consumed in the world for the production of fish meal and
fish oil as feed for aquatic animals, poultry and livestock. But by processing them, especially
the extraction of oil, fatty acids, and remaining fish proteins, they can be used in the
production of anti-inflammatory and pain-relieving drugs, lubricants, cosmetic products, and
cosmetic waxes. Industrial extraction of this product, while producing pharmaceutical
products, can improve the added value of fishery products and effectively help in reducing
environmental pollution.
Materials & Methods: In the present study, the isolation of unsaturated fatty acids and
steroids and the identification of sardine steroids of Sardinella sindensis species and the
production of moisturizing cream were performed in order to create value-added products.
Sardinella sindensis was caught by coastal blockade method in January 2017 from around
Qeshm Island. Bligh and Dyer method was used to extract oil from sardines. Unsaturated
fatty acids were measured in extracted fish oil. Finally, the production of moisturizing cream
from the extracted oil was investigated.
Results: The results showed that the amount of oil extracted from sardine fish using Bligh
and Dyer method is 16%. The highest amount of fatty acids is palmitic acid C16:0 (26/905).
The results of the moisturizing test of the produced creams on the skin of the volunteers
showed that the moisturizing of cream with 3% fish oil is 40.12% and the moisturizing of
cream with 5% fish oil is 42.31%, which according to the moisturizing creams Johnson
commercial 43.85% and Dr. Jila 44.90%, no significant difference was observed and the
produced creams were of good quality (P≤0.05).
Conclusion: The results show that by using cream containing 3% and 5% of optimized
sardine oil, the amount of skin moisture increases, which shows the lasting effect of creams
made from fish oil.
