Abstract

Modifikasi pati dilakukan untuk memperbaiki sifat fungsional pati dan memperluas penggunaan pati dalam produk pangan. Modifikasi pati menjadi dekstin dapat dilakukan baik secara fisik, kimiawi, atau kombinasi fisiko-kimia. Pada penelitian ini dilakukan modifikasi pati dengan kombinasi pregelatinisasi-steam explosion (Pregel-SE), dan kombinasi pregelatinisasi-asam sitrat-steam explosion pada pH 4 (pregel-pH-SE4) dan pH 3 (pregel-pH-SE3) untuk produksi dekstrin. Tujuan dari penelitian ini adalah untuk memperoleh metode hidrolisis terbaik dalam pembuatan dekstrin. Produk yang dihasilkan diamati tingkat kelarutan, berat molekul (Mw), dextrose equivalent (DE), Spectra Fourier Transform Infrared (FTIR), SEM, dan viskositas pasta. Hasil menunjukkan bahwa kondisi terbaik modifikasi pati menjadi dekstrin diperoleh pada perlakuan pregel-pH3-SE. Pada perlakuan ini diperoleh kelarutan 75,94 %, berat molekul 60100 g/mol dan DE 15,92%. Pita vibrasi baru terlihat di wilayah bilangan gelombang 1717 cm-1 pada analisis FTIR. Hasil SEM menunjukkan bahwa bentuk granula pati yang bulat sudah tidak terlihat setelah kombinasi perlakuan. Pengujian RVA menunjukkan penurunan viskositas berkorelasi positif terhadap penurunan berat molekul, peningkatan kelarutan dan DE setelah kombinasi perlakuan ditingkatkan. Starch modification is performed to improve the functional properties of starch and starch utilization in food products. Modification of starch, such as dextrin, can be performed by physical and chemical methods, or a combination method, such as physico-chemical. In this research, starch modification was carried out by a combination between pregelatinization and steam explosion (Pregel-SE), a combination between pregelatinization, citric acid and steam explosion at pH 4 (Pregel-pH-SE4) and at pH 3 (Pregel-pH-SE3) for the production of dextrin. The objective of this research was to obtain the best method for dextrin production. The results were observed, such as levels of solubility, molecular weight (Mw), dextrose equivalent (DE), Spectra Fourier Transform Infrared (FTIR), SEM, and pasting properties (RVA). The results showed that the best condition of starch modification for dextrin production was obtained by Pregel-pH3-SE. Solubility, molecular weight, and DE of dextrin were 75.94%, 60100 g/mol, and 15.92%, respectively. A new peak was observed in the region of the wavenumber 1.717 cm-1 at FTIR analysis. SEM analysis indicated that the round form of starch granules did not observed after the treatments. RVA analysis showed that the decrease in viscosity was correlated with a decrease in molecular weight, an increase in solubility, and DE after the treatments.

Abstract

The research was aimed at determining spray drying conditions during the production of smoke particulate powder and its consequences on the physical properties of the product. The experiment was carried out using a complete randomized factorial design. Samples were three solution of chitosan (CS)-maltodextrin (MD) based nanoparticles i.e. CS (0.5% w/v) and MD (9.5% w/v) in acetic acid (1.0% v/v) without liquid smoke (F1), only MD (10% w/v) in liquid smoke (F2) and a mixture of CS (1.5% w/v) and MD (8.5% w/v) in liquid smoke (F5). Each sample solution was prepared at 10% solid contents with addition of 1.0% sodium tripolyphosphate. The experimental factors were inlet air temperatures (T) of 130°C (T1) and 150°C (T2) and feed flow rate (L) of 2.4 mL/minute (L1) and 5.1 mL/minute (L2). The parameters evaluated included bulk density, yield, moisture content, water activity, morphology and particle size. Results showed that the average particle sizes decreased when the inlet air temperature increased. The bulk density, moisture content and water activity of powders tended to decrease with the increase of inlet air temperature. In contrast, the powder yield increased with increasing of inlet air temperature. Furthermore, characteristics of the powder particulates were spherical with smooth surfaces for all treatments but when the inlet air temperatures was high the particles has deeper surfacial grooving and shriveled, especially for sample F1.

OPTIMASI NANOENKAPSULASI ASAP CAIR TEMPURUNG KELAPA DENGAN RESPONSE SURFACE METHODOLOGY DAN KARAKTERISASI NANOKAPSUL [Optimization of Coconut Shell Liquid Smoke Nanoencapsulation using Response Surface Methodology and Nanocapsules Characterization]Dego Yusa Ali1), Purnama Darmadji2)* dan Yudi Pranoto2)1) Jurusan Teknologi Industri Pertanian, Fakultas Teknologi Pertanian, Universitas Jambi, Jambi2) Jurusan Teknologi Pangan dan Hasil Pertanian, Fakultas Teknologi Pertanian, Universitas Gadjah Mada, Yogyakarta Diterima 15 November 2013 / Disetujui 07 Februari 2014ABSTRACT Liquid smoke is impractical and easy to deteriorate, thus needs to be protected against deterioration. Spray drying technique is widely used to encapsule bioactive compounds. This study aims to determine the optimum encapsulant ratio and spray drying process to produce nanocapsule of liqud smoke. Nanocapsules production began with the mixing of encapsulant (chitosan and maltodextrin) and the liquid smoke and then agitated until dissolved. The solution of nanoparticles was heated in a water bath at 45°C for 5 minutes and homogenized using a homogenizer at 4000 rpm for 1 min. The nanoparticle solutions was spray dried at various temperatures and feed flow rates. Optimization is accomplished by using Response Surface Methodology (RSM), and the parameters to be optimized were chitosan concentration, inlet air temperature and feed flow rate of the spray dryer based on total phenolic content. Samples were analyzed for viscosity, pH, phenols staining, total phenolic, total carbonil, total acidity content, encapsulation efficiency, morphology profiles, and particle size distribution. The results showed that the nanoparticles solution of liquid smoke had a pH ranged between 2.55-2.64 total soluble solids ranged between 14-14.8°Brix and viscosity ranged between 8.7-14.9 centipoise (cP). The total phenolic content of the nanocapsules ranged from 1.38 to 2.32% with an efficiency ranged from 22.25 to 37.44%, and water content ranged from 9.56 to 10.73% (dry basis). The optimum conditions for the highest value of total phenolic content were 0.12% chitosan concentration, 140.65°C inlet air temperature and feed flow rate at 5.29 mL/min. The results suggested that nanocapsules had spherical and wrinkle shape with an average size of nanocapsules of 29.16 nm.
