Abstract

Jam is a food product with a gel or semi-solid consistency that is spread on food made from processed fruits and sugar without the addition of other food ingredients and permitted food additives. This study created a formulation of jam preparations from the albedo of watermelon rind (Citrullus lanatus Tunb.) in combination with guava fruit (Psidium guajava L.) because they contain vitamin C, which has antioxidant activity. The purpose of this study was to determine the formulation and antioxidant activity of the albedo jam preparation of watermelon rind (Citrullus lanatus Tunb.) and guava fruit (Psidium guajava L.). This study used a quantitative descriptive method with observations of jam quality according to SNI 01-3746-2008. The test parameters were jam quality tests, including organoleptic, pH, water content, colour test, and antioxidant activity tests. The organoleptic results of the jam had a bright red colour with a distinctive aroma of watermelon and red guava and had a slightly sour, sweet taste. The results of the pH test of the jam on F1, F2, and F3 were respectively 3.72 ± 0.025, 3.84 ± 0.017, and 3.85 ± 0.032. The results of the water content test of the jam on F1, F2, and F3 were respectively 29.34 ± 0.464, 29.18 ± 0.375, and 28.71 ± 0.437. The results of the jam colour test showed positive vitamin C content. The IC50 values of the jam preparations on F1, F2 and F3 were respectively 155.345 ppm, 145.581 ppm, and 130.241 ppm. The F1 jam preparation is a weak antioxidant, while F2 and F3 are moderate antioxidants.

Abstract:Date seed coffee is obtained by drying, roasting and grinding the date seeds. There are many benefits that can be obtained from the ingredients in date seeds, such as nourishing your stamina. The flavonoids contained therein also have antioxidant properties. Date seeds have also been developed into a coffee substitute. Therefore, researchers are interested in analyzing the content of flavonoids, caffeine and antioxidant activity in them. This research was conducted to determine the presence or absence of caffeine content, to determine the presence or absence and levels of flavonoids and strong antioxidant activity in dated coffee seeds. This type of research is quantitative with a descriptive research design. Date seeds are processed into coffee by drying the clean date seeds in the oven and then roasting them until the seeds are torn and quite burnt. Date seeds that have been roasted, crushed and sieve with a 60 mesh sieve. The date palm coffee powder was extracted by socletation using 80% ethanol as a solvent. The extracts of date seeds were analyzed qualitatively of flavonoids and caffeine with color testing, quantitative analysis of flavonoids with UV-Vis spectophotometry and antioxidant activity using the DPPH method. The qualitative test showed that positive date coffee seeds containing flavonoids was indicated by a red color change when reacted with Mg and HCl powder, and negative containing caffeine was indicated by a red color change when reacted with concentrated ammonia. In the quantitative analysis of flavonoids, the levels of flavonoids in dated seed coffee were 7523.03 ± 10.5078 mg QE / 100 g, and the antioxidant activity test showed that the level of IC50 in dated seed coffee was 26, 747 ppm. It shows that date seed coffee is free of caffeine, has a high content of flavonoids and has very strong antioxidants

Abstract

In today’s modern era many people consume unhealthy foods, which can lead to decreased immunity. One way to increase immunity is by consuming functional drinks from Avocado seeds and red ginger, which is contain flavonoid compounds. This study aims to determine antioxidant activity in functional drinks of avocado seeds by adding red ginger and stevia. The method used in this research is a quantitative analysis using the UV-Vis Spectrophotometer instrument at a wavelength of 418 nm for F1, F2 and F3 were brown, had a characteristic smell of spices, and had a distinctive taste. The pH test results were 6.243 ± 0.025, 6.167 ± 0.045, and 6.089 ± 0.005 respectively. The raw material and functional drinks positively contain flavonoids. Flavonoid content in F1, F2, and F3 were 12.214 ± 0.009428%, 12.419 ± 0.009428%, and 12.624 ± 0.009428% respectively. Antioxidant test results for functional drinks showed an IC50 value of F1 and F2 were 118.30 ± 1.57 ppm and 105.88 ± 1.11 ppm, which is categorized as moderate levels of antioxidants, and F3 was 88.09 ± 1.62 ppm, which is categorized as strong levels of antioxidants.
