Abstract
Abstract This research had been conducted in the use of avocado seed powder (Persea americana Mill) as an adsorbent to reduce peroxide and free fatty acids of the used cooking oil. The aim of this research was to determine the best activator of avocado seed powder as an adsorbent to reduce peroxide and free fatty acids of the used cooking oil. This research used the variation of activators, consist of hydrochloric acid (HCl), citric acid (C6H8O7), sodium chloride (NaCl) and sodium hydrogen phosphate (Na2HPO4) solutions. The result showed that the best activator of avocado seed powder by HCl which gave the highest free fatty acid reduction was 0,26%. Meanwhile, the best activator of avocado seed powder by C6H8O7 which gave the highest peroxide value reduction was 1,8 Meq/Kg . These results had qualified as the maximum limits of SNI cooking oil were 0.3% for the concentration of free fatty acids and 2 Meg/kg for the peroxide value of cooking oil. Keywords: adsorbent, avocado seed powder, used cooking oil
摘要以鳄梨籽粉（Persea americana Mill）为吸附剂，对食用油中的过氧化物和游离脂肪酸进行了吸附研究。本研究的目的是确定鳄梨籽粉作为吸附剂的最佳活化剂，以减少食用油中的过氧化物和游离脂肪酸。本研究使用了活化剂的变化，包括盐酸（HCl）、柠檬酸（C6H8O7）、氯化钠（NaCl）和磷酸氢钠（Na2HPO4）溶液。结果表明，用盐酸活化牛油果籽粉，游离脂肪酸还原率最高的活化剂为0.26%。同时，C6H8O7对鳄梨籽粉的最佳活化剂过氧化还原率最高，为1.8Meq/Kg。这些结果是合格的，因为对于游离脂肪酸的浓度，SNI烹饪油的最大限度为0.3%，对于烹饪油的过氧化值，SNI的最大限度是2Meg/kg。关键词：吸附剂、鳄梨籽粉、食用油
