Micrometer-Sized Fibrillar Protein Aggregates from Soy Glycinin and Soy Protein Isolate

Journal of Agricultural and Food Chemistry, 2007
Long, fibrillar semiflexible aggregates were formed from soy glycinin and soy protein isolate (SPI) when heated at 85 degrees C and pH 2. Transmission electron microscopy analysis showed that the contour length of the fibrils was approximately 1 microm, the persistence length 2.3 microm, and the thickness a few nanometers.

Natural Electroactive Hydrogel from Soy Protein Isolation

Biomacromolecules, 2010
A natural electroactive protein hydrogel was prepared from soy protein isolate (SPI) solution by cross-linking with epichlorohydrin. Under electrical stimulus, such SPI hydrogel quickly bends toward one electrode, showing a good electroactivity. Because of its amphoteric nature, the SPI hydrogel bends either toward the anode (pH < 6) or cathode (pH > 6)

Spectroscopic analysis of the effect of vitamin B12-soy protein isolate on the soy protein isolate structure

Journal of Molecular Liquids, 2021
Abstract In this paper, the influence of the interaction between vitamin B12 and soybean protein isolate (SPI) on the structure of the SPI was studied by Fourier transform infrared (FTIR), Circular dichroism (CD), and Raman spectra. The results of the FTIR and CD spectra show that when the concentration of vitamin B12 combined with the SPI increases,

Soy protein isolate–dialdehyde starch films

Industrial Crops and Products, 1998
Abstract This study was conducted to determine the effect of dialdehyde starch (DAS) on selected physical properties of cast soy protein isolate (SPI) films. Films were cast from heated (70°C for 20 min) alkaline (pH 10) aqueous solutions of SPI at 5 g/100 ml water, glycerin (50%, w/w, of SPI), and DAS at 0, 5, 10, 15, or 20% (w/w) of SPI.

Sulfite Formation in Isolated Soy Proteins

Journal of Food Science, 2006
ABSTRACT: Defatted soybean flour contained 2820 parts per million (ppm) inorganic sulfate. The corresponding laboratory isolated soy proteins (ISP) contained 1364 ppm sulfate bound to a greater than 3000 molecular weight fraction. Defatted soy flour contained 0.98 nmoles of adenosine triphosphate (ATP) per 0.1 g.

Hexanal Synthesis in Isolated Soy Proteins

Journal of the American Oil Chemists' Society, 2007
AbstractSodium erythrobate (2.3 mM) and dithiothreitol (6.5 mM) caused headspace hexanal from aqueous slurries of commercial isolated soy proteins (ISP) to increase by as much as 13‐fold compared with headspace hexanal in the controls. When linoleic acid was also added, headspace hexanal levels from commercial and laboratory‐prepared ISP were further ...

Thermal Aggregation of Soy Protein Isolates

Journal of Agricultural and Food Chemistry, 1995
Thermal behavior of soy protein isolates under different conditions of temperature, time, pH, protein concentration, and presence of reducing agents was studied. Thermal treatments above 85 °C showed a decrease in concentration of the AB-11s subunit and of the two protein species of 20 and 29 kDa, and a gradual increase in the concentration of the A ...

Emulsifying and physicochemical properties of soy hull hemicelluloses-soy protein isolate conjugates

Carbohydrate Polymers, 2017
Protein-polysaccharide conjugates could potentially combine the excellent emulsification properties of the protein with the stabilizing effect of the polysaccharide. The investigation aimed to prepare soy hull hemicelluloses-soy protein isolate (SHH-SPI) conjugates by Maillard reaction in a controlled dry state condition and assess the suitability of ...

Nanoparticle-Incorporated Soy Protein Isolate Films

2020
In the present scenario, demand of packed food is increasing exponentially, and this hike in demand of packed food focuses on the production of good packaging film with certain necessary qualities like biodegradability; non-hazardous, impressive mechanical strength; hydrophobicity; and longer shelf-life.

Biodegradable Soy Protein Isolate-Based Materials: A Review

Biomacromolecules, 2011
Recently, there is an increasing interest of using bio-based polymers instead of conventional petroleum-based polymers to fabricate biodegradable materials. Soy protein isolate (SPI), a protein with reproducible resource, good biocompatibility, biodegradability, and processability, has a significant potential in the food industry, agriculture ...
