Abstract

Onchidiid slug or Onchidium typhae is a marine animal commonly found in West Kalimantan waters. This gastropod is commonly used as medicine and cosmetic by the locals. This research aims to assure the content and quality of O. typhae methanol extract by determining its secondary metabolites and heavy metal contamination. Phytochemical screening of alkaloid, steroid/ triterpenoid, flavonoid, tannin, and saponin are done using reagent tests. Chromatography profile was completed using silica gel G60 F254 plate and hexane: ethyl acetate: methanol as mobile phase. Heavy metal contamination analysis was performed using atomic absorption spectrophotometry to determine Hg, As, Cd, and Pb content. The phytochemical screening and chromatography profile of O. typhae methanol extract confirm the presence of alkaloids and steroids. Heavy metal analysis stated Hg, As, Cd, and Pb content in O. typhae are < 0,0008; < 0,001; < 0,001; and 0,05 ppm respectively. Since heavy metal levels are below the maximum contamination limit, it qualifies as a natural product ingredient.

Abstract

Onchidiid slug (Onchidium typhae) is an animal with bioactive compounds with high nutritional value and the potential to be used as a functional food product. The study aimed to optimize the onchidiid slug instant powder formula, analyze its proximate content, and determine its hedonic level. The formula of instant powder was made with a comparison of the composition of maltodextrin and dextrose based on the run in the D-Optimal Mixture Design (DMD) program, namely run 1 (20%:10%), run 2 (10%:20%), run 3 (13.33%: 16.67%), run 4 (16.67%:13.33%), run 5 (15%:15%), run 6 (12.5%:17.5%), run 7 (10%: 20%), run 8 (20%:10%). The powder is tested for water content and dissolution time, and the optimal formula is analyzed using One Sample T-Test in SPSS. The results showed that the composition of maltodextrin and dextrose significantly affected the characteristics of instant powder. The optimal instant powder formula combines 18.690% maltodextrin and 11.310% dextrose with a water content of 4.892% and a soluble time of 118.052 seconds. The results of statistical analysis in verifying the optimal formula show a p-value > 0.05 (not significant). The results of the proximate content test were 8.21% water content, 0.42% ash content, 0.85% crude fiber, 3.54% protein, and 1.54%. They had a preference level in the like and acceptable in terms of color, taste, texture, and scent.
