Abstract Functional extracts from Soybean have numerous health benefits deriving from their content in isoflavones, especially daidzein and genistein, natural antioxidant and estrogen-like (ES-like) molecules. However, Soybeans denaturated dried extracts possess critical properties for industrial applications such as poor water-solubility and inadequate storage stability. The present research was aimed at developing a new Sodium-carboxymethylcellulose (NaCMC) matrix by spray-drying to microencapsulate soy extracts obtaining enhanced technological and permeation properties. Microparticles (NaCMC-Iso) loaded with marketed Soybeans extract (Iso), enriched in daidzein and genistein (about 90% w/w), were produced. Different liquid feeds, based on H2O/EtOH/acetone co-solvent systems, and various process parameters were tested to obtain a free-flowing and manageable powder with satisfying yield. The engineered NaCMC-Iso powders showed satisfying loading efficiency, high flow properties, good stability and enhanced technological properties. Interestingly, the in vitro dissolution and permeation rates were dramatically improved suggesting a higher bioavailability after the oral administration. The made-up powder appears a newsworthy ingredient of easier manipulation for enclosing in dietary supplements and nutraceutical products.

Abstract

Abstract Functional extracts from Soybean have numerous health benefits deriving from their content in isoflavones, especially daidzein and genistein, natural antioxidant and estrogen-like (ES-like) molecules. However, Soybeans denaturated dried extracts possess critical properties for industrial applications such as poor water-solubility and inadequate storage stability. The present research was aimed at developing a new Sodium-carboxymethylcellulose (NaCMC) matrix by spray-drying to microencapsulate soy extracts obtaining enhanced technological and permeation properties. Microparticles (NaCMC-Iso) loaded with marketed Soybeans extract (Iso), enriched in daidzein and genistein (about 90% w/w), were produced. Different liquid feeds, based on H2O/EtOH/acetone co-solvent systems, and various process parameters were tested to obtain a free-flowing and manageable powder with satisfying yield. The engineered NaCMC-Iso powders showed satisfying loading efficiency, high flow properties, good stability and enhanced technological properties. Interestingly, the in vitro dissolution and permeation rates were dramatically improved suggesting a higher bioavailability after the oral administration. The made-up powder appears a newsworthy ingredient of easier manipulation for enclosing in dietary supplements and nutraceutical products.
