The Effect of Concentration Areca Seed Extract (Areca Catechu L.) on Physicochemical and Sensory Properties of Pineapple Juice (Ananas Comosus L. Merr) As a Functional Beverages

This study aims to determine the effect of concentration areca seed extract on the physicochemical and sensory properties of pineapple juice as a functional beverages , and to determine the appropriate concentration of areca seed extract to produce pineapple juice that has the best physicochemical and sensory properties. This study used a completely randomized design (CRD) consisting of 4 levels of treatment, namely the concentration of areca seed extract 0%, 1%, 2%, and 3% (v/v). Each treatment was repeated 5 times, so there were 20 experimental units. The results showed that the concentration of areca seed extract had a significant effect on the total soluble solids, the degree of warmth L* and a*, antioxidant activity, total tannin, vitamin C levels, and had no significant effect on the acidity (pH), and had a characteristic taste of pineapple chelate until the taste of pineapple is slightly chelate, the color is brown to very brown, it has a pineapple aroma to a strong pineapple aroma, with a weak aftertaste to a slightly strong after taste. The best treatment in making pineapple juice with areca seed extract was the concentration of 2% areca seed extract which contained 80.02% antioxidant activity, vitamin C 104.68 mg/100 g, total tannin 99.62 mg TAE/g, total dissolved solids value 20.980brix, color degree value L*29.48, a*7.06, b*20.80, acidity value (pH) 3.37, has a slightly brown color, aroma of pineapple (methyl ester and ethyl ester compounds), taste pineapple and not chelate, and has no aftertaste

The Influence of Fermentation Conditions on The Antioxidant and Physico-Chemical of Arabica Coffee from Kerinci Region of Indonesia

Abstract—Coffee quality can depend on several factors such as the species/varieties cultivated, the processing after the harvesting phase, geographical origin, and climatic factors. Fermentation is one of the post harvest technology that influence coffee chemical and sensory properties. This study was to determine the effect of fermentation time into antioxidant and physicochemical of Arabica coffee from Kerinci region Indonesia. Research design used was randomized complete design with 5 combinations of treatments, which are 12, 20, 28, 36, and 44 hours fermentation with 3 replicates. The results shows fermentation time have a significant effects on moisture content, pH, antioxidant activity. The duration of fermentation results in increasing higher moisture content, lower pH value and decreased antioxidants. Keywords— Anaerobic fermentation, coffee processing, antioxida
