Abstract

Diabetes mellitus is a metabolic disease that occurs due to impaired insulin secretion caused by progressivedestruction of beta cells. Pineapple peel vinegar containing acetic acid and antioxidants has the potential to helpimprove the structure of beta cells in the Langerhans islet. This study aims to examine the effectiveness of pineapplepeel vinegar towards the histological improvement of Langerhans islet in diabetic rats. Twenty-four rats weredivided into 6 groups, normal control, positive control (diabetes + 0,4 ml apple vinegar), negative control(diabetes + water), test groups dose I, II, and III (0,2 ml; 0,4 ml; 0,8 ml pineapple vinegar). The treatment groupthat given 0.4 ml pineapple peel vinegar showed improvement in islet's structure as indicated by its size andnumber that close to normal. The results of the statistical analysis using Kruskal-Wallis followed by Mann-Whitneyshowed that the diameter of the Langerhans islet in group P2 (treated by 0,4 ml pineapple peel vinegar) was closeto normal. The improved structure of the Langerhans islet resulted in a decrease in blood sugar levels by 41,63%.This percentage is still lower than the K+ group (treated by 0,4 ml apple vinegar) by 52,89%. The antioxidantactivity in vinegar improves the structure of the Langerhans islet by binding to free radicals that cause damage.The acetic acid in vinegar inhibits disaccharidase activity so that it can control blood sugar levels.Keywords: Diabetes mellitus, alloxan, pineapple peel vinegar, antioxidants, acetic acid

Abstract

Diabetes mellitus is a metabolic disorder characterized by increased levels of glucose in the blood (hyperglycemia). The increasing number of diabetics in the world encourages the discovery of certain drugs that are effective and relatively safe for managing diabetes. One alternative medicine that can be used is vinegar. Pineapple skin can be an alternative raw material for making vinegar because it contains a large amount of sugar and contains acetic acid and various secondary metabolites that can reduce blood glucose levels. The purpose of this study was to determine whether pineapple skin vinegar has antidiabetic activity. The test was carried out by dividing each of the 4 rats into six groups namely normal control, positive control, negative control, and three test groups that were given pineapple skin vinegar as much as 0.2, 0.4, and 0.8 cc. The treatment was carried out for 28 days, starting 4 days after induction of an alloxan dose of 150 mg / kg body weight. Measurement of blood glucose and body weight of rats were carried out before induction, after induction, and on the 7th, 14th, 21st, and 28th day, while the measurement of feed consumption was carried out every day starting from the day of pineapple skin vinegar administration. The results of the analysis showed that the administration of pineapple skin vinegar by 0.4 cc with acetic acid levels of 1.43% can reduce blood glucose levels most significantly that is 41.63%.Keywords: vinegar, pineapple skin, acetic acid, antidiabetic

Abstract

Food spoilage can caused by pathogenic bacteria and can cause disease (food-borne pathogens). Foods that are vulnerable to pathogenic bacteria are foods that contain lots of protein, such as meat, milk and eggs. Listeria monocytogenes and Escherichia coli are commonly found in fresh meat. The solution for the problem is microbiological preservation by using Lactic Acid Bacteria (LAB). The purpose of this study is to isolate LAB from Apis mellifera honey, find out its characteristics, and test for antibacterial growth of L. monocytogenes and E. coli. LAB have been isolated with pour plate. Morphological characterization have been done by observing the colonies macroscopically and microscopically. LAB have been enumerated by Total Plate Count (TPC). Antibacterial Test have been done by well diffussion method. Experimental design was using Completely Randomized Factorial Design (CRFD). Statistical analysis have been done by univariate test with SPSS 16.0. 1st factor is LAB, 2nd factor is pH of supernatant and 3rd factor is pathogenic bacteria. Total 9 isolates of LAB were obtained from A. mellifera honey. LAB population is 9.6 x 105 CFU/mL. The result of screening LAB antibacterial assay is 2 potential isolates, they are MA 3 and MA 4. The best supernatant of LAB that could inhibit the growth of L. monocytogenes and E. coli is MA 3 with average diameters 12,05 mm and 12,07 mm. Pathogenic bacteria that is more sensitive is E. coli, because of the antibacterial compound from LAB is composed by organic acid that can break down the outer membrane and lower the pH, so pathogenic bacterial cannot be adapted to acidic environment.
