Abstract

Background; One of the preservatives that is permitted for use in food is sodium benzoate.Sodium benzoate is a salt or ester of benzoic acid (C6H5COOH) that is produced commercially through chemical synthesis. Sodium benzoate is also known as sodium benzoate or sodium benzoate. This preservative is a salt of sodium benzoic acid, a polyunsaturated fat that is approved for use by the United States Food and Drug Administration (FDA) and has been used by food and beverage manufacturers for more than 80 years to prevent microbial growth.Sodium benzoate has the molecular formula C7H5NaO2 and molecular weight Appears as odorless or almost odorless white crystalline granules or powder, soluble in 2.8 parts water and 90 parts ethanol (95%). Objective; This research aims to determine the extent of benzoate found in Tauco which is marketed in the Kisaran City Market. Method; The analysis was carried out using a qualitative method with the aim of determining the Tauco benzoate content using the FeCl3 test, esterification test and sublimation test, quantitative methods using UV-Vis spectrophotometry and to determine the sodium benzoate content according to established standards. Absorbance was measured by UV-Vis spectrophotometry at a maximum wavelength of 225 nm. Result;The results showed that the sodium benzoate content was Ten Tauco samples are A= 125.8555 mg/kg, B= 71.1929 mg/kg, C= 98.9557 mg/kg, D= 174.3942 mg/kg and E = 78.9945 mg/kg.. meet The standard requirement for the maximum use limit is 450 mg/kg. Conclusion; The conclusion of this research is that the sodium benzoate content meets the requirements and does not exceed the maximum threshold set by BPOM No. 36 of 2021, namely 450 mg/kg Tauco.

Abstract

Background: The current state of Indonesian society in general is concerning. People want to use motorized vehicles to travel instead of walking or cycling. All this leads to an increase in the amount of unfastened radicals inside the body. Antioxidants are needed to overcome the risks of unfastened radicals. Indonesia is very rich in herbal sources consisting of numerous flora, one of which is the telang flower (clitoria ternatea l.) which is thought to have antioxidants. Activity: To determine the antioxidant activity of telang flower (Clitoria ternatea L.) by dpph (2,2-Diphenyl 1-1 Picrylhydrazyl). Method: Antioxidant activity test can be done by using several kinds of methods, namely dpph, abts, etc..Results: Classification of secondary metabolite compounds found in flower telang (Clitoria ternatea L.) includes alkaloids, flavonoids, quinones, saponins, tannins, and steroids with the technique used with the DPPH test. The results of the test sample for the extract of telang flower (Clitoria ternatea L.) have an IC50 of 356.65 ppm and are classified as very weak. The ic50 value assessment of the ethanol extract of telang flower (Clitoria ternatea L.) with methanol as solvent has a value of 95.Conclusion: Assessment of antioxidant activity can be assessed from IC50. The IC50 assessment of the flower telang (Clitoria ternatea L.) has obtained different results, namely the weak and strong IC50. This can be influenced by the maximum wavelength used, as well as the storage temperature of the extract of a plant. In addition, a good solvent, namely methanol, is needed in measuring the IC50 of telang flower (Clitoria ternatea L.) using DPPH.
