Bromelain Immobilized onto Clay-Carboxymethylcellulose Composites for Improving Nutritive Value of Soybean Meal.

Improvement of nutritional value and reduction of antinutritional factors (ANFs) of soybean meal (SBM) for animal feed applications could be achieved by using bromelain immobilized onto bentonite (Bt)-carboxymethylcellulose (CMC) composites. The composite with mass ratio between CMC to calcium ion (Ca) at 1:20 provided the highest enzyme activity, immobilization yield higher than 95%, with superior thermal and storage stabilities. Performance of the immobilized bromelain for soybean protein hydrolysis was further studied.

Printable-Microencapsulated Ascorbic Acid for Personalized Topical Delivery.

This study presents the successful development of printable-microencapsulated ascorbic acid (AA) for personalized topical delivery using laser printing technology. Rice flour with a 10% AA content was selected as an encapsulation material. Hydrophobic nanosilica was used to create negative electrostatic charges on the microencapsulated surfaces via a high-speed mixture.
