Abstract


Pati millet putih alami mempunyai beberapa kendala jika dipakai sebagai bahan baku dalam industri pangan, yaitu pati alami tidak tahan pada pemanasan suhu tinggi dan tidak tahan pada proses mekanis, sehingga kurang cocok untuk diaplikasikan pada produk yang memerlukan proses pemanasan tinggi seperti saus. Oleh karena itu, perlu dilakukan modifikasi pati untuk memperbaiki sifat pati alami tersebut. Modifikasi yang digunakan dalam penelitian ini adalah modifikasi secara Heat Moisture Treatment (HMT) dan annealing. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan sifat fungsional dan amilografi pati millet putih alami dengan pati millet putih yang termodifikasi secara HMT dan annealing. Hasil penelitian menunjukkan bahwa modifikasi HMT dan annealing dapat memperbaiki sifat pati alami tersebut, yaitu meningkatkan ketahanan terhadap panas dan proses mekanis. Berdasarkan grafik amilogram, pati termodifikasi HMT memiliki pola viskositas tipe B sehingga cocok diaplikasikan untuk produk saus dan pati termodifikasi annealing memiliki pola viskositas tipe A sehingga cocok diaplikasikan untuk produk roti. Modifikasi HMT menyebabkan terjadinya penurunan swelling volume, freeze thaw stability, kekuatan gel, derajat putih, kadar air, viskositas puncak, viskositas pasta panas, viskositas breakdown, viskositas pasta dingin, dan viskositas setback pati millet putih alami serta peningkatan kelarutan, kapasitas penyerapan air, DE, dan suhu awal gelatinisasi pati millet putih alami, sedangkan modifikasi annealing menyebabkan terjadinya penurunan swelling volume, freeze thaw stability, kadar air, viskositas puncak, viskositas pasta panas, viskositas pasta dingin, dan viskositas setback pati millet putih serta peningkatan kelarutan, kapasitas penyerapan air, kekuatan gel, derajat putih, DE, suhu awal gelatinisasi, dan viskositas breakdown pati millet putih.

Abstract

Native millet starch has several problems when used as raw materials in the food industry, which is native millet starch can not stand on the high temperature heating and can not stand on the mechanical process, so that it doesn’t suitable for products that require high heating process such as sauces. Therefore, native starch had to modified to improve the properties of the native starch. Modifications that used in this study were Heat Moisture Treatment (HMT) and annealing. The aim of this study was to determine the differences of functional and amylograph properties of native millet starch with HMT and annealing millet starch. Results from this research was HMT and annealing modification can improve the properties of the native starch, which increase resistance in thermal and mechanical process. Based on the amylogram graph, HMT starch has a type B pattern that properly used for sauces and annealing starch has a type A pattern that properly used for bakery products. HMT modification cause decrease in swelling volume, freeze thaw stability, gel strength, whiteness, water content, peak viscosity, hold viscosity, breakdown viscosity, final viscosity, and setback viscosity of native millet starch, and also increase in solubility, water absorption capacity, DE, and gelatinization temperature of native millet starch, while the annealing modification cause decrease in swelling volume, freeze thaw stability, moisture content, viscosity peak, hold viscosity, final viscosity and setback viscosity of native millet starch and increase in solubility, water absorption capacity, gel strength, whiteness, DE, gelatinization temperature and breakdown viscosity of native millet starch.
