The present application relates to the field of polymer manufacturing, and particularly relates to a long-chain branched modification method of rare earth isoprene rubber and / or butadiene rubber, comprising the following steps: S1. performing solution polymerization of isoprene and / or butadiene and isoprene in a non-polar solvent in the presence of a rare earth catalyst to obtain a glue solution containing active polymer molecular chains; S2. when the conversion rate of the polymerization reaction reaches 95% or more, adding a compound branched modifier to the glue solution to perform a branched reaction; wherein the compound branched modifier comprises at least one of a chloride and an alkyl halide and at least one selected from ether compounds and tertiary amine compounds. The branched modifier used in the present application has a strong branching effect, and has good solubility so as to achieve uniform mixing at a molecular level in the glue solution, significantly alleviates the gel side reaction, reduces the gel content, narrows the molecular weight distribution, significantly improves the raw rubber performance, and improves the product uniformity.

The invention provides a preparation method and application of a protein nanocage loaded with tuna peptide. The preparation method specifically comprises the following steps: constructing and modifying an iron protein nanocage, and extracting, screening and embedding tuna active peptide. The tuna active peptides are embedded in ferulic acid modified ferritin nanocages, and are delivered into intestinal tracts in a targeted manner to react with anorexia hormone receptors, so that the generation of anorexia hormones such as cholecystokinin, glucagon-like peptide 1 and PYY is regulated, the appetite after normal diet is controlled, and the satiety of the body is enhanced; the effects of reducing food intake and reducing body weight are achieved, so that the composition plays a role in regulating obesity. Ferulic acid is utilized to modify the ferritin nanocage, carboxyl and phenolic hydroxyl groups in the ferritin nanocage react with amino terminals on the outer surface of the ferritin nanocage, so that the ferritin nanocage is endowed with a gastric juice environment resisting function, and the ferritin nanocage can stably exist in the stomach of an organism without being decomposed, so that the ferritin nanocage is decomposed in intestinal tracts and plays a role in precise targeting; and a foundation is laid for anti-obesity research.
