Formation of bioactive nanoparticles with reduced crystallinity using nanoporous starch aerogels: A novel approach to enhancing the bioavailability of the water-insoluble bioactives

Aerogels have been attracting a growing interest due to their outstanding surface area, porous structure, and light weight. We form biodegradable nanoporous aerogels from starch using a simple and green method based on supercritical carbon dioxide (SC-CO2) drying. Due to high surface area and nanoporous structure, nanoporous starch aerogels (NSAs) are promising carrier systems for bioactives and drugs in food and pharmaceutical industries. Read more

Development of an extraction and purification process to obtain high purity and alternative natural wax from sorghum

There is a growing demand for natural wax sources due to growing applications, dwindling waxes supply, and increasing wax prices. Grain sorghum is a promising alternative natural wax source with properties similar to Carnauba wax. Sorghum wax can be extracted from sorghum kernels, sorghum DDGS, and sorghum bran. As an alternative to hexane, there is a growing interest in using supercritical carbon dioxide (SC-CO2) for the extraction. Read more

3D food printing

Development of high-oil-content food inks for 3D food printing and microstructure controlling via particle engineering

Three-dimensional (3D) food printing is a novel technology that allows the creation of 3D edible objects with customized shape, structure, flavor, texture, and tailored nutrition in a layer-by-layer manner. Compared with traditional processing methods, 3D food printing offers a shorter running period, low cost at low-volume production, and low waste production. Rheological properties of food inks and optimization of printing parameters have been considered the most crucial factors in extrusion-based 3D printing. The complex microstructure should also be considered fundamental to determine the rheology, mechanics, and function of the printing inks and must be addressed to the achievements in 3D food printing. High liquid oil content is a challenge for 3D food printing as it increases the ductility and destroys the deposited effect. As the promising future of 3D food printing is to produce personalized foods, there is a critical need to investigate the interaction of liquid oil with other macronutrients on printability as it will offer new opportunities for 3D food printing.

Astaxanthin rich camelina seeds oil

Enrichment and isolation of astaxanthin from camelina seed oil by enzymatic modification in SC-CO2: A novel green separation and purification process

Currently, enzymatic esterification is used commercially to produce a variety of modified lipids such as free trans margarine, shortenings, and low-calorie structured lipids. Enzymatic esterification offers more advantages such as milder processing conditions, fewer by-products, and easier product recovery compared to chemical esterification. Lipases are the most established biocatalysts used for the synthesis of structured triacylglycerols, fats, and margarine. Supercritical carbon dioxide is a favorable solvent that can aid the hydrogenation at milder conditions and decrease undesired by-products due to its unique properties. Astaxanthin, as a high-value red carotenoid with health and wellness promoting properties has attracted much attention in recent years. Read more
