Abstract

Formalin is a solution which made from 37% formaldehyde in water which is commonly used as preservative for cosmetic products and various types of non-food industrial materials. The use of formalin as a preservative in food is very dangerous for health. The purpose of this study was to determine the presence of formalin found in skewered meatballs circulating in several elementary schools in the city of Manado. Sampling was done in Malalayang Elementary School (A), State Elementary School 6 Manado (B), State Elementary School 9 Manado (C) and State Elementary School 29 Manado (D). In a qualitative test, Nash reagents were used to determine the presence of formalin in the sample. Nash reagent was used to indicate the presence of Formalin content in a sample marked with a change in color to yellow. The results of this study showed that twelve samples of skewers from four elementary schools in Manado City did not contain formalin or safe from formalin use.   Keywords: Formalin, Formaldehyde, Skewered Meatballs, Nash Reagent, Qualitative Analysis  ABSTRAK Formalin merupakan larutan yang dibuat dari 37% formaldehida dalam air yang umumnya digunakan sebagai bahan pengawet produk kosmetik dan berbagai jenis bahan industri non makanan.

Abstract

The presence of free radicals produced inside the cells is thought to cause a range of diseases such as degenerative diseases. Antioxidant properties of carrot root (Daucus carota L.) have been reported elsewhere to inhibit the formation of these free radicals, but the compounds responsible for antioxidant activity inside its leaves have not yet determined. In Indonesia, Daucus carota L. leaves are regarded as waste product after harvesting the root. This study was conducted to isolate and identify the compound having antioxidant activity from the leaves of D.carota. n-Hexane, ethyl acetate, and methanol extracts were examined for free radical scavenger activity by using DPPH method. The n-hexane extract showing free radical scavenger activity was solid-solvent partitioned, fractionated using vacuum liquid chromatography and tested for free radical scavenger activities. The active compound was isolated by using preparative thin layer chromatography and its purity was determined by TLC with three mobile phase systems and two dimensional TLC. Based on spectroscopy UV-Vis, IR as well as 1H-NMR (CDC13) data, the active compound was suggested to be xanthophyll derivate, lutein. The compound at concentration of 0.616, 1.025, and 2.05 ppm had antioxidant activities of 0.94 ± 0.05; 18.53 ± 0.15; and 49.07 ± 0.86, respectively.

Abstract

Sago Baruk (Arenga microcarpha) is one of endemic crop type of Archipelago of Sangihe Talaud, North Sulawesi and potential as source bioactivities including antioxidant. The objectives of this research were to determine the chemical characteristics and antioxidant activity of starch sago baruk which was sequentially extracted with water and filtrate. The sago trunks pith was sequentially extracted with water and filtrate at room temparature for 1 hour. After that, starch of sago baruk were analyzed for their chemical composition (moisture, fat, protein, ash crude fiber and charbohydrate) and total phenolic and tannin condensed content. Antioxidant activity of each sago flour were evaluated in 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and total antioxidant capacity. After that, the starch was characterized by IR spectroscopic technique. The sequential extraction result indicated percentage yield of starch I and starch II were 41.39% and 38.21%. The chemical characteristics of starch I revealed that percentage protein, ash, crude fibre and fat were below 1% than starch II especially protein and fiber crude. The starch I had highest total phenolic and tannin condensed content than starch II and starch K. The starch I also showed the highest free radical scavenging activity in 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical than starch II and starch K. The result also showed that starch I has strongest total antioxidant capacity than starch II and starch K at all concentration level. Antioxidant activity of three starch increased with the increase in concentration of the samples. The three starch showed of hidroxy (OH), carbonyl (C=O), ether (C-O) and aliphatic group (C-C). It is concluded that starch sago baruk especially the starch I are very rich in antioxidant substituens.
