Abstract

The use of bulk cooking oil repeatedly with long storage time results in oil damage, such as increasing the peroxide value and acid number. So far, to overcome this problem, synthetic antioxidants are still used such as Butylated hydroxytoluene (BHT). When BHT added bulk cooking oil will be carcinogenic. Seeing this, it is necessary to look for alternative natural antioxidants. This study aims to seek out the effect of adding natural antioxidants, namely shallot powder to the peroxide value and acid number in bulk cooking oil with storage times of 0, 4, and 8 days. The peroxide number was determined by iodometric titration, while the acid number by acid-base titration. The data obtained were processed with statistics. The results of the statistical data of the Kruskal-Wallis test obtained a sig value of 0.000 less than 0.05, which means that there is an effect of adding shallot powder to the peroxide value and acid number. It shows that shallots are effective as natural antioxidants and can improve the quality of bulk cooking oil.

Abstract

Oil is used as a medium for frying food that is widely consumed by the public. One way to overcome rancidity by improving the quality of oil by using antioxidants. Antioxidants consist of synthetic antioxidants and natural antioxidants. The use of synthetic antioxidants such as BHA (Butyl Hydroxy Anisol) and BHT (Butyl Hydroxy Toulene) raises many concerns about side effects such as causing swelling of the liver and affecting enzyme activity. Therefore, it is necessary to look for other alternatives, namely natural antioxidants. Natural antioxidants are antioxidants extracted from natural plant and microbial materials. One of the plants that has the potential to be utilized as a natural antioxidant is Rosella Flower. This aims of this study was to determine the effect of adding rosella flower powder as a natural antioxidant and to determine the quality of bulk cooking oil after adding Rosella Flower Powder to bulk cooking oil stored for 0 and 7 days. This study uses the Iodometric Titration method, data obtained by statistical tests and comparison with Indonesian National Standard number 01-3741-2013. The results of the analysis with Post hoc LSD test showed that the use of rosella flower powder almost equaled BHT and was said to be one group.
