Starch emulsification

Pin milling alone improved one functional property, oil emulsification (Table III). The pin-milled flours, protein fractions and proteinates gave oil emulsification values of 70.0-79.0% compared to values of less than 18.0% for starch products. 

For alkaline sizing both corn and potato cationic starches are suitable. In practical usage, however, potato cationics with about 0.3% nitrogen added appear to be the product of choice. These are used at the wet end and for emulsification.

Improved stability towards oxidation of spray dried flavor oils was achieved by using a combination of a high-maltose syrup, maltodextrin and a high molecular weight, film-forming polysaccharide, such as starch octenylsuccinate or gum ara-bic.200 201 Emulsification performance of maltodextrins is improved by treatment with octenylsuccinic anhydride and aluminum sulfate. 

Emulsifier/stabilizer systems are normally used to make stable food emulsions. Thus, lecithin is generally not called on to handle the entire emulsification, but it works in combination with other emulsifiers and stabilizing polymers such as proteins, starches, and gums (31). Lecithin will break up (emulsify) the particles, and a stabilizer (water-soluble polymer, etc.) will hold the particles in a dispersed orientation when a stable emulsion is formed. 

The previous subsections have considered homogeneous solutions and gels. We now address water relaxation in heterogeneous particulate suspensions, pastes and powders. We focus on the starch-water system since starch is widely used as a thickener, texturizer and emulsification aid in the food industry.

Starch added as an emulsification agent makes little or no contribution to inter-fibre bonding. When a size emulsion droplet is retained on a fibre surface, upon rupture of the droplet the encapsulating starch attached to the fibre surface remains covered with the hydrophobic size and is unable to contribute to fibre bonding. Such starch should not be included when considering the starch requirements for increased paper strength. 

Starches for size emulsification need a higher DS to ensure retention of the emulsion droplet. Starch used for size emulsification makes little or no contribution to sheet strength. 

Abstract New acylation techniques were developed for the fabrication of fatty estos of cellulose and starch. They exclude the use of organic solvents and are readily achieved. Emulsification of the fatty acid in water allowed die intimate contact between the tty recent and die polysaccharide. Fatty acid salts (soap) were used as both catalyst and emulsifying agent. Reaction conditions were optimized using an experimental design. Starch and cellulose octanoates were obtained having a DS of 0.52 and 0.23 with a recuperation yield of 70 and 85 %, respectively. Both polysaccharide esters showed a marked hydrophobic character. 

Emulsification of cellulose or starch with water or ethanol, soap and a fatty acid is a performing method to allow the grafting of fatty chains onto the biopolymer backbone. An experimental design allowed to determine the best conditions to synthesize starch fatty esters with DS < 0,5 using natural raw materials as reagents.
