Banana tree (Musa parasidica) is an environmental waste that can be extracted from starch and used as an innovative product high in food fibre and potential probiotics by adding pineapple pulp (Ananas comosus)(Reference Setianingsih1). This study aims to process or formulate and utilize Banana Tree Starch with the addition of pineapple pulp into a functional food product in the form of probiotic drinks. In addition, in vitro levels of antioxidants (especially vitamin C) and total dietary fibre were also carried out.
There are 3 variations of the formulation, Banana Tree Starch: Pineapple: CO2 free water. Sample 1 (1: 0.5: 0.5), sample 2 (2: 1: 1) and sample 3 (3: 2: 2). Then, all product samples were inoculated with Lactobacillus paracasei for 60 hours and incubated in anaerobic conditions with a temperature of 30-32°C. Sample variation was carried out to determine the significance of the average antioxidant content in it. The next step is to test the analysis of vitamin C from 3 variants of beverage samples using the Iodometric Titration Method, to determine the amount of Vitamin C (mg/100g) and the antioxidant activity with 2.2-diphenyl-1-picrylhydrazyl (DPPH). Determination of dietary fibre content using the AOAC method. All with triple repeat per sample.
The amount of vitamin C obtained at S1 was 80.45±0.05 mg/100 g with 44.95±0.99% antioxidant activity and 11.01±0.01% dietary fibre. S2 respectively 65.75±0.05 mg/100 g with antioxidant activity of 30.60±0.30% and 8.90±0.10% dietary fibre. S3 was 47.02±0.02 mg/100 g with 32.10±0.20% antioxidant activity and 7.89±0.10% dietary fibre. The fermented drink sample formulation containing the highest vitamin C was S1. There was a significant difference (P < 0.05) which determined the vitamin C levels between the sample formulations. The average ash content of the three samples was 4.77±0.07% and the moisture content was 37.72±7.72%. The average vitamin C level in the three fermented drink samples was 64.40±16.75 mg/100g. S1 showed the best activity, namely the antioxidant activity against 2.2-diphenyl-1-picrylhydrazyl (DPPH) of 44.95±0.99% and also had high levels of dietary fibre and high vitamin C.
The formulation of a combination of banana tree starch with the addition of pineapple pulp has great potential to be developed into a health functional food. By looking at the content of vitamin C and total dietary fibre and antioxidants in the fermented products, this can be an effort to diversify local food and can be an alternative to anti-diabetic drinks and other infectious diseases(Reference Jayedi, Rashidy-Pour and Parohan2).
