The research has been carried out in the Processing and Chemistry Laboratory of Politeknik Pertanian Negeri Payakumbuh and Post Harvest Laboratory in Bogor since July until November 2006. The research objectives was to prolong the using time of used cooking oil on food industries through applying the empty fruit bunch of palm bioadsorbent. The optimum condition of TKKS applied were 125 mm size and 5% bioadsorben from the weight of oil (Desminarti dan Rahzarni, 2004). The prolonging of cooking oil application can be done throughrefining used cooking oil so that the part of bad cooking oil can be lremoved. Statistical design used in this research was Completely Randomized Design with four treatments dan three replications. If the result was significant it will be followed by DMRT test on 5% significant level. Based on the experiment could be concluded that that four times titration could produced the oil based on SNI criterya in the relation to the water content (0.23%), peroxide value (0.82%) and free fatty acid value (0.23%) and it could also decrease Fe content from 76ppm to 22 ppm, Cu from 1.2 ppm to 0.40 ppm and Non Urea Adduct Forming (NAF) from 126 ppm to 102 ppm. The bioadsorbent sorption content on water varied from 78% to 80%; peroxide value from 14.71 to 59.80%, free fattyacid from 55.61 to 89.25%, Fe from 68.42 to 71.05%, Cu from 5% to 60% and NAF from 17.46 to 19.05%.

Intake of unsafe food causes many acute and life-long diseases, ranging from diarrheal diseases to various forms of cancer. Thus, it is imperative that safety issues on food adulteration and heavy metals contamination be evaluated for the benefits of the consuming public. Consequently, oxidation stability and heavy metal analyses on used cooking oil and four selected street-vended foods from three different sampling sites were done. Analyses of test parameters were performed using standard methods and procedures. Overall results of the analyses with three trials each showed that peroxide value, free fatty acids, cadmium (Cd) and lead (Pb) did not conform to the allowable levels set for the food products. The peroxide value was three to eight times higher than the limit of 10meq/kg since it ranges from 33.33 - 86.67meq/kg whereas Cd and Pb showed concentration of 0.60 – 1.57 ppm and 30.00-35.00 ppm, respectively. On the other hand, percent free fatty acids (%FFA) ranges from 0.72 to 0.93% on used cooking oil while selected street-vended foods FFA status were recorded at the range of 1.49 to 2.92%. The results clearly indicate oxidative rancidity due to repetitive use of cooking oil and heavy metal contamination on the test samples which were found to be significantly higher than the maximum limits. This could mean that prolonged exposure to these street vended foods is detrimental to human health. The high level of POV, Cd and Pb of these products can significantly pose food poisoning, foodborne disease, neurotoxicity and even cancer.

High Peroxide

Used cooking oil is a cooking oil that has been used several times. Used cooking oil undergoes an oxidation reaction to produce high peroxide compounds. Phenolic compounds are primary antioxidants contained in Moringa leaves which slow the oxidation down in used cooking oil so that it can be stored longer. Formulation of the problem in this study was whether there was an inhibitory test on Moringa oleifera Leaves powder on the peroxide value in used cooking oil. The purpose of this study was to determine the inhibition of Moringa leaves powder to peroxide value on used cooking oil. This type of research was an experimental i.e. to determine whether there was the inhibition of Moringa leaves powder to the peroxide value in used cooking oil. The sample in this study was 5 samples from 6 fried traders, and repeated 5 times so that the total sample was 25 samples. Peroxide levels could be decreased due to the antioxidant content found in Moringa leaves. Antioxidants found in Moringa leaves are phenolic components. Phenolic components can inhibit free radicals and inhibit peroxide value to decrease. Moringa was suitable for areas where strong and long winds, drought occur simultaneously, and cause serious soil erosion. Nutrient content in deciduous leaves could fertilize and improve marginal soil quality (Dudi, 2015). Therefore, Moringa leaves not only have high antioxidants but also could be found easily in Surabaya. From the results of peroxide levels test, it was known that the average peroxide value in used cooking oil without Moringa leaves was equal to 23,9957 mEq and with Moringa leaves by different time variation i.e. 1 day (14,3182 mEq), 2 days (10,7987 mEq), 3 days (6,1593 mEq), 4 days (3,0397 mEq). Statistical analysis with Anova test showed the inhibition of Moringa leaves powder to decrease in peroxide value on used cooking oil with a value of p (sig) = 0,000 which was less than 0.05. Based on the results of the Tukey HSD test, the most effective soaking of Moringa leaves powder for 4 days was to reduce peroxide levels in used cooking oil by giving 5gr Moringa leaf powder with 100ml used cooking oil.

Oxidation Parameters

Used cooking oil is widely used by Indonesian people to fry many foods, which is the oil have been oxidized. On the other hand, Indonesia has a lot of unutilized waste products, such as bagasse. The design of the study was experimental, which added the bagasse to the used cooking oil to filtrate the physical and chemical impurities. There were 3 kinds of treatments, i.e. F1 (3% of bagasse), F2 (5% bagasse), F3 (7% bagasse), and control (without bagasse).<strong> </strong>The characteristics of used cooking oil (control) were: dark brown, rancid odor, having 0,39% of free fatty acid, 12,39 meq/Kg of peroxide value, 35,52% w/w palmitic acid, 35,31 oleic acid, 9,35% w/w linoleic acid, and 3,32% w/w stearic acid. The best treatment taken on the highest yield, organoleptic test, and peroxide number was F1 (3% bagasse), it could reduced free fatty acid and peroxide value become 0,26% and 6,67 mEq/kg. The number of fatty acids from the best treatment were dominated by palmitic acid (33,94% w/w), oleic acid (33,92% w/w), linoleic acid (9,03% w/w) and also had stearic acid (3,21% w/w).<strong> </strong>The bagasse can significantly reduce the organoleptic properties, the oxidation parameters, and other fatty acids of used oil (P&lt;0,05). So, the bagasse could potentially decrease the oxidation parameters of used cooking oil.
