Product Development of Effervescent Tablets from Indian Borage (Coleus amboinicus Lour.) Extract for Detoxification of Pesticide Residues in Vegetables

Abstract

Vegetables are a source of vitamins, minerals, dietary fiber and phytonutrients that are beneficial to health. Many consumers are concerned about pesticide residues in vegetables, which could negatively affect health. Although there is information about the method of cleaning vegetables from various media, there is no clear information about the efficiency of such washing. In this study, we studied the extraction of Indian borage (Coleus amboinicus Lour.) that has active compounds for bacteria, mold, and yeast inhibitions. In addition, it shows properties as an insecticide, toxic elimination and no toxic residue. Product development of effervescent tablets from Indian borage consisting of citric acid, tartaric acid, sodium bicarbonate and extract of Indian borage in a ratio 1: 2: 3.44: 1. The result found that concentrated extract 90% w/v was appropriate for maximum weight per tablet 6.85±0.01 g, dissolution in 1.20±0.09minute, pH 7.02. The efficiency of eliminating pesticide residues in vegetables by using a TV-KIT test kit combined with the color measurement of the solution by the Munsell color system demonstrated that 1 effervescent tablet of Indian borage extract dissolved in 1 liter of water could eliminate the pesticide residues in the samples by 100% compared to washing with water and sodium bicarbonate. The product can be stored in air-sealed bags for at least 45 days. Using Indian borage extract to develop as an effervescent tablet product for removing toxic residues in vegetables is an alternative product for cleaning vegetables before consumption. Also, it is convenient to use.
