Effect of Giving Mangrove Leaf Extract (Acanthus Ilicifolius) and Teak Leaf Extract (Tectona Grandis) on Iron (Fe) Beef Exposed to Gamma Radiation

This study uses beef given gamma radiation exposure and uses a mixture of mangrove leaf extract (acanthus illicifolius) and teak leaf extract (Tectona grandis) as an antioxidant that can reduce the formation of abnormal iron (free iron) in beef which will be a catalyst and is a major factor in the formation of free radicals that destroy the nutritional content in beef. This study aims to determine the effect of gamma radiation exposure on the amount of iron (Fe) beef as well as to determine the effect of giving a mixture of mangrove leaf extract (acanthus illicifolius) and teak leaf extract (Tectona grandis) on beef exposed to gamma radiation. This study used 600 pieces of beef, dice size (1 cm x 1 cm x 1 cm x 1 cm) with a weight of 0.5 gram each, and grouped in groups exposed to radiation and given a mixture of extracts. Antioxidants are given in 3 concentrations of 2%, 6% and 10%. While gamma radiation exposure is given for 1 hour, 2 hours, 3 hours, 4 hours and 5 hours. Analysis of iron content was carried out using the SSA (Atomic Absorption Spectrophotometry) method. The results showed that exposure to gamma radiation can cause an increase in the amount of iron (Fe) which can be seen from the high percentage of the amount of iron (Fe) measured from the test results. However, the administration of a mixture of the two extracts showed a decrease in iron (Fe) levels with the best reduction results at low extract concentrations.
