Abstract

Background: Chitosan, a natural polysaccharide derived from chitin deacetylation, shows potential as a natural edible coating to extend the shelf life of perishable fruits. Utilizing giant African snail (Achatina fulica) shells as a chitosan source offers a sustainable solution to reduce biological waste while replacing synthetic chemicals in food preservation. Objective: This study aimed to analyze the effectiveness of snail shell chitosan as an edible coating in maintaining the physicochemical quality of tamarillo (Solanum betaceum) during storage. Methods: Chitosan was isolated from snail shells and applied at concentrations of 10%, 20%, and 30%. Antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa was tested using the disc diffusion method. Physicochemical parameters including weight loss, moisture loss, color, pH, total acidity, vitamin C content, and total soluble solids (TSS) were measured over 7 days of storage. Results: Chitosan demonstrated strong to very strong antibacterial activity, with the largest inhibition zones at 30% concentration (29 mm for S. aureus; 33.8 mm for P. aeruginosa). The 30% chitosan treatment yielded optimal results: lowest weight loss (3.15%), moisture loss (5.75%), pH (7.72), total acidity (16.44%), and TSS (1.350). Vitamin C retention was significantly higher in the 30% chitosan group (551.47 mg/100g) compared to control (416.53 mg/100g), confirming its effectiveness in inhibiting oxidation. Conclusion: 30% snail shell chitosan proved effective as an edible coating for maintaining tamarillo's physicochemical quality, while providing a natural and sustainable solution for the food industry.

Abstract

Medicines can cause changes in the physiology or psychology of an organism when consumed. In general, medicines consist of several mixtures of active ingredients such as paracetamol (PCT), propifenazone (PRO), and caffeine (KAF), which are often found in several types of branded medicines that are claimed to be able to cure or treat. This research aims to obtain a type of solvent that has the smallest photometric error value and can completely dissolve the active ingredient mixture of PCT, PRO, and KAF. In general, organic solvents such as ethanol and methanol are very often used to dissolve compounds that mix with each other, but these solvents cannot always dissolve other active substances. Therefore, researchers carried out an analysis of several types of solvents that could dissolve the three active ingredients. Solvents that can dissolve perfectly without any specification stage must go through a solvent optimization process. The types of solvents that will be tested are methanol, HCl 0.1N, phosphate buffer pH 7.2, and the ratio of phosphate buffer: methanol (DM) (DM 9:1 pH 7.4), (DM 7:3 pH 7.8), (DM 5:5 pH 8.3), (DM 3:7 pH 8.9), and (DM 1:9 pH 9.6). The results of this research show that the solvent that has the smallest photometric error value and can completely dissolve the three active substances is the DM 7:3 pH 7.8 solvent with a total percentage of 0.0846%, which is the smallest value compared to other solvents that have been optimized.
