Effect of extrusion treatment on the thermal stability and structure of corn starch with different emulsifiers
crystallinity modified starches extrudate complexes
2015/10/9
Corn starch was treated with raw moisture (30%), screw speed (160 rpm), extrusion temperature (30, 55, 80, 105, 130, and 155°C), and emulsifier (1.2%) to produce the starch extrudate particles in a tw...
Exopolysaccharide from Lactobacillus helveticus: identification of chemical structure and effect on biscuit duality
exopolysaccharide Lactobacillus helveticus biscuits xanthan LB-gum rheological properties chemical quality attributes sensory evaluation
2014/2/27
Exopolysaccharide (LB-gum) was produced from Lactobacillus helveticus by ethanol precipitation and gel-permeation chromatography. The structures of LB1 and LB2 were estimated by sugar composition anal...
Studies on the structure and oxidation properties of extracted cooked cured meat pigment by four spectra
Extracted cooked cured meat pigment Structure Oxidation properties Electron paramagnetic resonance (EPR) HPLC/ESI-HR-MS FT–IR Raman spectra
2012/8/13
The structure and oxidation properties of cooked cured meat pigment (CCMP) were investigated by comparing the change in spectra of CCMP before and after oxidisation. CCMP was extracted using petroleum...
Analysis and Control of Ice Crystal Structure in Frozen Food and Their Application to Food Processing
ice fraction effective thermal conductivity pressure-shift freezing
2009/6/18
The large differences in thermal properties between water and ice cause thermal properties of frozen food to be strongly dependent on ice fraction, which is a function of solute concentration and temp...
Meat quality assessment using biophysical methods related to meat structure

2012/8/13
This paper overviews the biophysical methods developed to gain access to meat structure information. The meat industry needs reliable meat quality information throughout the production process in orde...
Identification and Manipulation of Subsite Structure and Starch Granule Binding Site in Plant α-Amylase
α-amylase subsite starch granule
2008/4/20
In germinating plant seeds, α-amylases degrade starch accumulated in seeds, and that requires two functions: catalysis itself and starch granule binding ability. All plant α-amylases belong to the α-a...
Crystal Structure of GH54 α-L-Arabinofuranosidase and Unique Function of CBM42 Attached to It
crystallography glycoside hydrolase family 54 α-L-arabinofuranosidase arabinose-binding domain carbohydrate-binding module family 42
2008/4/20
As the first known structures of a glycoside hydrolase family 54 enzyme, we determined the crystal structures of free and arabinose-complex forms of α-L-arabinofuranosidase from Aspergillus kawachii I...
A Note on the Metabolic System for the Synthesis of the Tandem-Cluster Structure of Amylopectin in Rice Endosperm
amylopectin cluster rice starch branching enzyme starch debranching enzyme starch synthase
2008/4/20
The tandem-cluster structure of amylopectin must be a refined product that higher plants have evolved from the cluster-free random branched structure of glycogen. During the evolutionary process, plan...
Structure and Function of Exo-β-glucosaminidase from Amycolatopsis orientalis
Amycolatopsis orientalis exo-β-glucosaminidase chitosanase subsites chitooligosaccharides
2008/4/20
We cloned and sequenced the gene encoding exo-β-glucosaminidase (GlcNase) from Amycolatopsis orientalis, and found that the gene has an open reading frame of 1032 residues with a calculated molecular ...
