Effects of different wall-breaking methods on the nutrient release of Ganoderma lucidum spore powder during in vitro digestion.

Background: The hard double-walled structure of Ganoderma lucidum spore powder (GLSP) is difficult for the human body to digest, so it is very important to break the wall of GLSP. In this study, the wall of GLSP was broken by mechanical milling at room temperature (MM-R) and ultra-fine grinding at low temperature (UFG-L), respectively.

Results: Compared with MM-R, UFG-L could better retain the sporangium powder's morphological and structural integrity.

Extended Dynamic Mode Decomposition with Invertible Dictionary Learning.

The Koopman operator has received attention for providing a potentially global linearization representation of the nonlinear dynamical system. To estimate or control the original system, the invertibility problem is introduced into the data-driven modeling, i.e.

Impact of particle size on the nutrition release and antioxidant activity of rape, buckwheat and rose bee pollens.

In this study, the effects of particle size on the microstructure, nutrient components and antioxidant activities of bee pollen were evaluated. Moreover, the simulated digestion model was used to explore whether there was a size effect on the release behavior of phenolic compounds from the bee pollen matrix. Results showed that the greater the damage degree of the bee pollen wall, the smaller the bee pollen particle became.
