“…The results of the absorbance of the Arabica Gununghalu coffee in various concentrations with the light roasting, medium roasting, and dark roasting techniques obtained are changed to the percentage of inhibition using equation (1). Based on the inhibition calculation in Figure 1, the greater concentration of the sample, the smaller the absorbance value, and the greater percentage of inhibition, these results are consistent with several previous studies (Rahmawati et al, 2022;Kurang and Kamengon 2021). The highest antioxidant activity value in the light roasting of Gununghalu Arabica coffee bean with an inhibition percentage of 36.21% with a concentration of 100 ppm solution.…”

Coffee is one of the popular drinks for Indonesian people. Coffee consumption in Indonesia has increased very rapidly. The influence of lifestyle and the increasing number of cafes and coffee shops contribute to the increase in coffee consumers. One downstream processing of coffee beans is roasting coffee beans, which consists of light, medium, and dark roasting. This study aimed to determine the antioxidant activity of Gununghalu Arabica Coffee (Coffea arabica L.) with Light Roasting, Medium Roasting, and Dark Roasting Techniques. This research is an experimental study, where the antioxidant activity analysis was carried out using the DPPH method (2,2-diphenyl-1-picrylhydrazyl). Gununghalu Arabica coffee with light, medium, and dark roasting techniques positively containing flavonoids, alkaloids, saponins, tannins, and terpenoids. The results showed that the IC50 value of Gununghalu Arabica coffee for light, medium, and dark roasting was 102.94 ppm, 70.66 ppm, and 87.66 ppm. The test results show that the antioxidant activity of Gununghalu Arabica coffee with light roasting techniques are moderate, while medium and dark roasting techniques are strong. The results of this study are expected to provide implications for the development of coffee processing techniques to have maximum health benefits.

“…Antioxidant Activity are chemical compounds that can inhibit or stop the oxidation process and can give one or more electrons to free radical molecules so that they can break chain reactions and free radicals [27]. Antioxidants function to prevent various types of diseases caused by free radicals such as cancer and coronary heart disease [3]. The treatment with the addition of CMC had no significantly different effect, while the treatment with the addition of albedo watermelon juice to yogurt had a significant effect on the antioxidant activity of yogurt.…”

This research aims to determine the effect of adding Carboxy Methyl Cellulose (CMC) and watermelon albedo juice. on antioxidant activity, physical properties and organoleptic properties of watermelon albedo yogurt. This study uses Completely Randomized Design (CRD) with the first factor was CMC concentration (0%, 0.2%) and the second factors was Watermelon albedo juice concentration (0%; 20% and 30%). with trplicate. Parameters to be observed include antioxidant activity, pH, viscosity, syneresis and sensory test (aroma, taste and texture). Observational data were tested by ANOVA at a 5% and continued using the Honestly Significant Difference (HSD) at a significant level of 5 %. The best yogurt was the addition of 0.2% CMC and 30% watermelon albedo juice concentration which produces of antioxidant activity 29.67%, pH value 4, 21, syneresis 12.37% and viscosity 3759.33 cP. The sensory resulted in a slightly sweet taste and strong watermelon aroma preffered by the panelists.

Moringa oleifera, which is known as a drumstick tree in different areas of the world, is well‐known for many health benefits, which are attributed to the abundance of flavonoids, phenolic chemicals, and thiocyanates it contains. This review focuses on M. oleifera’s potential for neuroprotection, emphasizing its anti‐inflammatory, antioxidant, and neurotransmitter‐modulating qualities. Different parts of M. oleifera include leaves, roots, bark, and gum. Flowers, seeds, and seed oil are used for many health purposes, most notably in the treatment of neurological diseases. Neurodegeneration, which is characterized by the progressive death of nerve cells, is a major concern with an aging population, leading to disorders such as dementia and movement disorders. M. oleifera bioactive compounds improve the antioxidant defense activities of the brain, reduce inflammation, and improve neurotransmitter levels, showing potential therapeutic applications for neurodegenerative disorders. This review emphasizes the importance of further research, especially clinical trials, to fully understand and utilize M. oleifera’s neuroprotective capabilities.
