Interfacial protein engineering for spray-dried emulsions – Part II: Oxidative stability

Nutritive quality and protein production from grain legumes in a boreal climate

“…Amino acid analysis followed the standard procedure from Commission Directive 98/64/EC with quantification by a UPLC Amino Acid Analysis Solution System (Waters, Milford, MA, USA). For fatty acid analysis, lipids were extracted using acetone as solvent by accelerated solvent extraction, methylated and analyzed by gas chromatography (GC) using standard methods …”

“…For fatty acid analysis, lipids were extracted using acetone as solvent by accelerated solvent extraction, 23 methylated and analyzed by gas chromatography (GC) using standard methods. 24 wileyonlinelibrary.com/jsfa Since mechanical dehulling did not result in clean fractions of cotyledons and seed coats, a volumetric approach was used for the determination of seed coat content. Seed dimensions of 100 seeds of cultivars Kontu, Aurora and Mélodie harvested in 2009, 2010 and 2011 were measured with a precision micrometer, and seed volume was estimated from the standard mathematical equation for a smooth ellipsoid (volume = × r 1 × r 2 × r 3 × 4/3).…”

Effect of oil droplet size on the oxidative stability of spray-dried flaxseed oil powders

“…The hydroperoxides formed by oxidation of α-linolenic acid, which is the main PUFA in flaxseed oil, produce various volatile degradation compounds, including propanal, pentane, hexanal, 2-trans-and 3-cis-hexenals, heptadienal, octanal, and nonanal. 28) These components cause off-flavors and affect the odor of oils, even at extremely low concentrations of 1 ppb. 30) Vinaixa et al 31) reported that an increase in conductivity detected in the CDM evaluation is strongly correlated with the intensity of the rancid odors measured using metal oxide sensors and mass spectrometry.…”

“…Bao et al 27) demonstrated that the oxidative stability of microcapsules formed by spray drying of algae oil could be improved by cross-linking of the bovine casein layer using transglutaminase. Damerau et al 28) reported that the amount of hexanal present in spray-dried sunflower oil powder decreased by about one third over the course of 29 weeks with the use of cross-linked SC with storage at 22°C and a relative humidity of 54%. iii, iv) SC and (v, vi, vii, viii) PSC with (i, ii, v, vi) large and (iii, iv, vii, viii) small oil droplets.…”

New Trends in the Microencapsulation of Functional Fatty Acid‐Rich Oils Using Transglutaminase Catalyzed Crosslinking

“…Although the use of TGase could strongly lead to the formation of continuous polymer film surrounding the core, the physical characteristics of spray‐dried powders were not affected by the enzymatic crosslinking. Damerau and others () showed that PSC crosslinked with TGase through the modification of the interaction behavior of emulsified oil droplets can positively change the oxidative stability rate of sunflower oil in spray‐dried powders under different storage settings. Partanen and others () also had earlier stabilized a protein foam by the TGase‐induced cross‐linking of SC via creation of a thin film.…”
