This study aimed to find relationships between the properties of beeswax-based oleogels and the type of oil used. The influence of linseed, sunflower, olive, and fish oils was studied. For these oils, the fatty acid composition, the content of total polar components, and the iodine value were characterized. Textural and thermodynamic properties were determined for oleogels, the oil-binding capacity was estimated, and the morphology of crystals was studied. The concentration of beeswax in all oleogels was 6.0% w/w. It was shown that the type of oil has a significant influence on all characteristics of the oleogels. The use of different oils at the same technological treatment leads to the formation of crystals of diverse morphology—from platelets to spherulites. At the same time, it was revealed that some characteristics of oils have a varying contribution to the properties of oleogels. The content of total polar materials in oils is associated with a decrease in strength parameters (yield value and elastic modulus) and the oil-binding capacity of oleogels. In its turn, the iodine value of oils has a close positive correlation with the melting and crystallization temperatures of oleogels. The results obtained in this article indicate that the properties of beeswax-based oleogels can be directed by changing the oil composition.

Flaxseed oil cake extract (residual from cold-press oil production and rich in proteins and polysaccharides) was evaluated as a potential substrate for the preparation of spray-dried powders with emulsifying activity. Three variants of powders were obtained using different spray-drying process inlet temperatures: 160 °C, 180 °C, and 200 °C. The influence of temperature on physicochemical features (water holding capacity, oil binding capacity, water activity, solubility, color, chemical composition, antioxidant activity, and surface morphology) of the powders was estimated. Additionally, the emulsifying activity of the powders and the stability of oil-in-water emulsions prepared with their various content (0.5%, 1%, and 3%) were determined. Results showed that inlet temperature had significant influence on all physicochemical and functional properties of the powders. Increased inlet temperature decreased solubility and antioxidant activity but increased water-holding capacity, oil-binding capacity, and emulsifying activity. The emulsions prepared with the powder obtained at 200 °C showed the highest stability. SEM images showed the production of relatively spherical particles which were folded or wrinkled with a lot of dentures. This study could open a promising pathway for producing natural and plant-based spray-dried powders for food applications as emulsion stabilizers.

Abstract This research focuses on the use of protein-polyphenol complex and protein-polyphenol: polysaccharide complexes to prepare oleogels through an emulsion-templated approach. Electrolysis soy protein isolate (ESPI) could be effectively adsorbed on the surface of a single-layer emulsion to increase the particle size. The order of the negative charges of the emulsion after adding polysaccharides was xanthan gum (XG)> pectin> carboxymethyl cellulose (CMC). Rheological behavior showed that the stability of the double-layer emulsions increased, and the viscoelasticity increased around one order of magnitude with the addition of polysaccharides. The oil binding capacity (OBC) of the oleogel prepared by adding polysaccharides increased to more than 97%. The peroxide value (PV) and anisidine value (AV) of XG oleogel were the minimum values in all samples. The AV and POV were within the regulatory limits of China after storage for 21 days. This provides a reference to design of ESPI-based oleogel for different applications.

The structural and functional properties such as solubility, emulsifying properties, foaming properties, oil binding capacity, and surface hydrophobicity of sunflower 11S globulin hydrolysates generated by Alcalase at hydrolysis time of 30, 60, 90, and 120 min were evaluated. Circular dichroism analysis showed the hydrolysates possessed a decreased α-helix and β-structure. The hydrolysates exhibited lower surface hydrophobicity. Hydrolysates with shorter hydrolysis time showed the higher emulsifying activity index, but the same emulsion stability and oil binding capacity compared to the original 11S globulin. The longer hydrolysis resulted in lower foaming and emulsion stability. Thus it was demonstrated that by controlling the hydrolysis time of sunflower 11S globulin, hydrolysate with a desirable functional properties can be obtained.

ABSTRACT Traditional marine oil response technology is based on ship borne techniques with oil/water separation by skimmer. These systems are very sensitive to weather conditions and have a long response time. Furthermore, conventional solid binder systems are unsuitable for marine application. Within the research project BIOBIND, a new binder system for marine application was developed and evaluated. The oil binders are made of biogenic and biodegradable wood-fiber, which cause only a small environmental impact and are very cost-efficient. They show a high porosity of 85 %, a high oil absorption capacity of approx. 600 kg m−3 (especially for thin oil films down to 0.03 mm), and a high retention capacity for oil. On the water surface, these binders achieve an oil recovery rate of 80 % with a coverage dosage of 11 %. Having a square geometry of 50 x 50 mm and a thickness of 4 mm, the binder has superior properties for manufacturing, storage, oil adsorption and recovery. The binder system was produced in industrial scale and tested during a large scale field experiment at the Baltic Sea in the summer of 2013. Its binding capacity and flotation ability were evaluated in mesocosm tests. Because of its hydrophobic properties, the binder floated for more than 8 days. Experiments of airborne application, monitoring, and ship borne recovery confirmed the suitability of the binder system. Due to airborne distribution, the binder system is also suitable for application during bad weather conditions and on shallow water territories. The paper describes the development of a solid oil binding system suitable for new marine application and presents the results of laboratory scale, mesocosm and field experiments.

Before And After

Maternal interest in their own and alien lambs was examined in groups of 7-11 ewes before and after their lambs were coated with nonpolar substances (white soft paraffin or liquid paraffin), or more polar substances (polyethylene glycol, glycerol, silicone oil or diisooctylphthalate). Maternal interest in alien lambs was significantly increased by smearing lambs with the nonpolar material, but the effect was absent when lambs were washed before coating; more polar coatings had little or no effect. The coatings had little or no effect on the maternal interest in the ewe's own lambs. We suggest that coatings of polar materials, while dissolving polar components from the skin and wool, does not prevent the release of volatile nonpolar constituents which ewes employ to distinguish between lambs. We also suggest that nonpolar coatings dissolve and retard the release of lamb odour components of similar polarity, while permitting the release of other constituents which appear generally attractive to maternal ewes, and result in increased acceptance of alien lambs.
