Abstract

The purpose of this study was to determine the antioxidant activity of fermented tea (black tea) with Ketapang leaves (Terminalia catappa) using two variations of leaf age, namely leaflets 1-3 and 4-5. The parameters observed were water content, pH, antioxidant activity (IC 50) and total phenol content of tea. Results showed that the antioxidant activity of young leaves (shoots 1-3) significantly higher than old leaves (shoots 4-5) but had lower total phenol and pH. In general, the character of Ketapang leaf tea products at shoots 1-5 has water content ranging from 5.55-5.58%, total phenol content of 22.63-28.97 mg / g EAG, and antioxidant activity (IC 50) of 6.27-6 .71 µg/ml and the pH of steeping water from 5.9 to 6.1.

Abstract

The aim of this study was to determined the effect of mocaf flour and maize to the mocatilla chips physical properties and organoleptic properties. The study design using RAL method with one parameter added mocafflour as much as 0% as control, 15%, 30%, 45% and 60% (w / w). Each treatment using 3 experimental replicated unit. Analysis of texture products include mechanical testing, moisture content test and organoleptic test. Added mocaf flour ranging from 15% to 60% in the mocatilla chips no significant effect on water content but caused changes in texture becomes harder to value% deformation increased from 20.39% to 30.53%. Organoleptic characteristics on mocatilla chips has changed in color, taste, aroma and texture after adding mocaf flour compared with control, and overall the highest score of 4.6 panelists acceptance found on the product mocatilla chips with the addition of as much as 15%, so the addition of mocaf flour 15% can be used for the production mocatilla chips. it is not different physical characteristics and organoleptic with control (0% mocaf).

Abstract

Processing figs into food and beverage products will increase the attractiveness to consume this nutrient-rich fruit. One of them is by processing it into syrup. The purpose of this study is to (1) Knowing the effect of the stevia sugar concentration on the physical and chemical characteristics of fig syrup; (2) Knowing the effect of the carboxymethylcellulose (CMC) concentration on the physical and chemical characteristics of fig syrup. The experimental design used in this study was a completely randomized design (CRD) factorial pattern with two treatment factors, namely the concentration of stevia sugar (A) with four types of treatment levels, A1 = 0% (100% sucrose); A2 = 1%; A3 = 2%; A4 = 3%. Concentration of CMC (B) with three types of treatment, B1 = CMC 0%; B2 = CMC 0.25%; B3 = CMC 0.5%. Each treatment was repeated twice to obtain  4 x 3 x 2 = 24 experimental units. The results show the brightest color produced by 100% sucrose with CMC 0% which is equal to 36.24 (L). The highest sugar content was produced in syrup with the addition of stevia 3% and CMC 0% which amounted to 34.46%. The highest viscosity is produced in syrup with the addition of 100% sucrose and CMC 0.5% which is equal to 365.2 cP.)

Abstract

Cellulose is the main constituent of cell walls in plants, cellulose (C6H10O5) n is a long-chain polymer of polysaccharides, 1,4-beta-D-glucose. Cellulose can be extracted from corn stalks with a yield of 35.61%. This cellulose can be used as a base for making edible films other than starch. Improving the physicochemical quality of edible film can be done by adding a plasticizer, such as sorbitol. The aim of this research is to produce edible film from cellulose corn stalks with the addition of sorbitol as a plasticizer. The experimental design used in this study was a completely randomized design with one factor, namely the concentration of Sorbitol (A) with 6 treatment levels, namely A1 = 0% (control), A2 = 1 ml; A3 = 2 ml; A4 = 3 ml; A5 = 4 ml and A6 = 5 mL. Each treatment was repeated three times in order to obtain experimental units 6 x 3 = 18 experimental units. The product analysis carried out was the thickness, tensile strength, and pH of the edible film. The results showed that the best edible with the highest tensile strength value was obtained when the addition of 4 ml sorbitol was 9.45 MPa.
