Starch in Emulsion-Type Sausage Reduced the Gastric Digestibility of Meat Protein by Reducing the Stability and Increasing the Viscoelasticity of Gastric Digests.

The effect of the addition of native starch (S) and modified starches (distarch phosphate (SP), acetylated distarch phosphate (AP), and starch acetate (SA)) in emulsion-type sausage on the digestion process of meat protein was studied in this work. The addition of native and modified starches reduced the release of -NH during the simulated gastric digestion stage, whereas the addition of SA increased the total release of -NH after the whole digestion. Peptidomic analysis revealed that the presence of starch decreased the release of peptides in the gastric digestion.

[Diversity of soil seed banks under different vegetation types in the southeastern margin of the Tengger Desert, China].

To explore the dynamics and distribution of soil seed banks under different vegetation types in desert, and reveal the community succession tendency and diversity characteristics of different vegetative types, we took community, community, community and community as the research objects in the southeastern margin of the Tengger Desert. Samples of 0-2 cm, 2-5 cm, 5-10 cm, and 10-20 cm soil layers were collected. We examined the characteristics of soil seed banks and their relationships with vegetation.
