Efendi, Renvianti and Prof.Dr.Ir.Harijono, M.App.Sc (2020) Optimasi Ukuran Partikel, Tingkat Keasaman Pelarut Berbasis Air Dan Lama Ultrasonic-Assisted Extraction Polisakarida Larut Air-Bukan Pati Biji Asam (Tamarindus indica L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Indonesia adalah salah satu negara penghasil asam jawa dengan produksi mencapai 3485 ton dari luas areal sekitar 4249 ha. Hidrokoloid polisakarida biji asam jawa dapat digunakan sebagai pengental, emulsifier, dan bahan pembentuk gel. Polisakarida dari biji asam dapat diperoleh dengan cara ekstraksi. Penggunaan Ultrasonic-Assisted Extraction (UAE) berpotensi diterapkan untuk ekstraksi hidrokoloid polisakarida biji asam. Tujuan penelitian ini untuk menentukan kondisi optimum ukuran partikel bahan, tingkat keasaman pelarut dan lama ekstraksi polisakarida larut air-bukan pati (PLA-BP) biji asam jawa menggunakan UAE dan menentukan komposisi ekstrak PLA-BP. Metode yang digunakan Response Surface Methodology dengan rancangan percobaan Box-Behnken Design. Kondisi optimum ekstraksi PLA-BP adalah ukuran partikel 60 mesh,15 menit dengan pH pelarut 8. Kondisi tersebut menghasilkan rendemen sebesar 61,760%bk dan kelarutan sebesar 57,183%. Ekstrak polisakarida pada kondisi optimum mengandung kadar air 2,193%; kadar abu 2,821%, kadar lemak 2,683%; dan kadar protein sebesar 19,349%
English Abstract
ndonesia is one of the tamarind producer with production rate reach 3485 tons from an area of around 4249 ha. Hydrocoloid polysaccharides of tamarind seeds can be used as thickeners, emulsifiers, and gelling agents. Polysaccharides from tamarind seeds can be obtained by extraction. The use of Ultrasonic-Assisted Extraction (UAE) has the potential to be applied for the extraction of hydrocoloid tamarind seed polysaccharides. The purpose of this study was to determine the optimum conditions for particle size, solvent acidity and extraction time for water- soluble non-starch polysaccharides (PLA-BP) of tamarind seeds using UAE and to determine the composition of PLA-BP extracts. This method used Response Surface Methodology with a Box- Behnken Design (BBD) experimental design. The optimum conditions for PLA-BP extraction are 60 mesh particle size, 15 minutes with solvent pH 8. These conditions produce a yield of 61.760%bk and solubility of 57.183%. Polysaccharide extracts at optimum conditions contain a moisture content of 2.193%; ash content 2,821%, fat content 2,683%; and protein content of 19,349%.
