Abstract: A selenium-chelating pea oligopeptide, a preparation method thereof and use thereof. After the selenium-chelating pea oligopeptide is subjected to digestion treatment in at least one of following three ways, a change rate of selenium content not more than 3% with respect to the selenium content before the digestion treatment: hydrolyzing for 4 hours by a pepsin at a pH value of 2 and a temperature of 37° C.; hydrolyzing for 6 hours by a trypsin at a pH value of 7.5 and a temperature of 37° C.; maintaining the temperature constant at 37° C., firstly hydrolyzing for 4 hours by the pepsin at a pH value of 2, and then continuing to hydrolyze for 6 hours by a trypsin at a pH value of 6.8. The preparation method thereof includes mixing and reacting an aqueous solution of pea oligopeptide and sodium selenite, and then being subjected to alcohol precipitation and drying.

Abstract: Disclosed are a fish protein oligopeptide with low allergenicity and slight fishiness, and industrial preparation method and application thereof. The method comprises the following steps: 1) washing fresh fish flesh and/or fish wastes, crushing, and adding water to obtain a mixture; 2) performing thermal denaturation on the mixture to obtain a denaturized protein solution; 3) centrifuging the denaturized protein solution to obtain a precipitate, and adding water into the precipitate and grinding, to obtain a slurry; 4) adjusting the slurry to pH 6-9, and sequentially adding a neutral protease, a papain and an alkaline protease to conduct enzymolysis, and after enzyme inactivation, to obtain an enzymatic hydrolysate; 5) centrifuging the enzymatic hydrolysate, and performing membrane filtration on centrifuged supernatant, to obtain the fish protein oligopeptide with low allergenicity and slight fishiness.

Abstract: An injection mold including a connecting structure for separating confronting faces of a slide member and a mold base, respectively, during a movement of the slide member. In accordance with several embodiments of the invention, the connecting structure may include a compressible member such that the slide member is biased away from the mold base, and wherein a positive contact between the confronting surfaces is configurable in response to an applied clamping force between the slide member and the mold base. In accordance with an alternative embodiment of the invention a cam arrangement links the slide member and the mold base enabling a positive contact between the confronting surfaces when the slide member is arranged in the in-mold position, and providing a gap between the confronting surfaces during at least a portion of an interval when the slide member is moving.
