Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.9443

Abstract: Abstract According to the plant stress hypothesis, population peaks of herbivores such as moths are caused by plant stress factors that force plants to reallocate stored defensive proteins to transportable and easily digestive N‐compounds. A… read more here.

Published in 2021 at "Journal of the science of food and agriculture"

DOI: 10.1002/jsfa.11418

Abstract: BACKGROUND The relatively inferior techno-functionality, especially for the emulsifying and antioxidant activities of flaxseed protein/polysaccharides complexes partially limited its implication in health food system. The current study aimed to conduct the effects of atmospheric pressure… read more here.
