The invention discloses a pure highland barley powder extrusion puffing process optimization method, and belongs to the technical field of food extrusion processing. According to the method, the technical problems that the high-fiber highland barley powder is easily subjected to insufficient puffing and too hard texture in the extrusion process, and the retention rate of heat-sensitive functional components such as beta-glucan is low are solved. The method comprises the following steps: optimizing process parameters based on a multi-target response surface method, and determining the water content of materials, the temperatures of a first region, a second region, a third region and a fourth region of a machine barrel and the rotating speed of a screw; carrying out low-temperature superfine grinding on the highland barley powder; a compound emulsifier and edible sodium bicarbonate are added during hardening and tempering; during extrusion, the temperature gradient between the third area and the fourth area is controlled to be smaller than or equal to 20 DEG C; the method is mainly used for producing the high-quality pure highland barley puffed food, the puffing rate and the beta-glucan retention rate of the product can be synergistically improved, the hardness of the product is effectively controlled, and the eating quality and the nutritional value are improved.

A thermoplastic polyester elastomer is provided, particularly exhibiting excellent extrudability and extrusion stability, and capable of stably producing hollow and elongated molded articles with uniform thickness through extrusion molding over extended periods. A polyester elastomer is composed of hard segments and soft segments bonded together, wherein the hard segments are composed of polyesters consisting of aromatic dicarboxylic acids and aliphatic or alicyclic diols, and the soft segments are composed of aliphatic polycarbonate. At least a portion of the terminal groups of the polyester elastomer are capped with a reactive compound containing polycarbodiimide. The acid value of the polyester elastomer is 15 eq / ton or less, and at 230°C, (i) the melt viscosity at a preheating time of 5 minutes and a shear rate of 10 / s is 1800 Pa·s or more, and the melt viscosity at a preheating time of 5 minutes and a shear rate of 1000 / s is 800 Pa·s or less; and (ii) the ratio of the melt viscosity at a shear rate of 10 / s measured at preheating times of 5 minutes and 25 minutes is 0.7 to 1.3.
