چکیده

Intrinsic factors affecting the rate of starch digestion in foods are the physical form of food, shape and crystal structure of the starch granule, recrystallization and retrogradation, amylose-lipid complexes, native α-amylase inhibitors and non-starch polysaccharides [1]. For nutritional purposes, starch is classified into three types based on these intrinsic factors: rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS) [1]. Resistant starch can be further classified into four types: Type I RS (physically inaccessible starch)[1], Type II RS (resistant starch granules) [1], Type III RS (retrograded starch)[1] and Type IV RS (chemically/heat treated starch)[2].

Comparative Studies on Effect of Pretreatment of Rice Husk for Enzymatic Digestibility and Bioethanol Production

Three common pretreatment processes based on dilute sulfuric acid, dilute sodium hydroxide and heat treatment (autoclaving) followed by enzymatic hydrolysis were evaluated to provide comparative performance data. Among them, the best result was obtained when the pretreatment of rice husk was carried out with 3% of NaOH solution. The pretreatment of rice husk with NaOH substantially increased th...

Rice grain quality: related properties and effective factors

Rice provides food for more than half of the world's population. Unlike other cereals used in the form of processed, rice is mostly consumed directly with removal of paddy and brown husks. Therefore, considering rice grain quality is one of the main factors in product marketability and consumption. Rice grain quality can be considerd and evaluated by assessment of four properties: physical, che...

The Physicochemical Properties of Starch Component of six Iranian Rice Cultivars

Using a wide range of techniques, including differential scanning calorimetry, X-ray diffraction, Rapid Visco Analyser and Fourier Transform Infera Red Spectroscopy, some physicochemical properties of the starch fraction of six Iranian rice cultivars (Tarom, Tarome Hashemi, Neda, Ramezani, Fajr and Kamfirouzi) [1]were studied and compared. DSC data showed that starch granules of different rice ...
