The invention discloses a preparation method for sea cucumber peptide, belonging to the technical field of aquatic product processing. The preparation method comprises the following steps: weighing cooked fresh sea cucumber without internal organs, immersing the sea cucumber in liquid nitrogen, taking the sea cucumber out, then soaking the sea cucumber in hot water with a temperature of 95-97 DEGC, and then carrying out stirring and washing; adding the cleaned sea cucumber into a cooking and enzymolysis tank for cooking, and after completion of cooking, starting the stirrer and the shearer ofthe cooking and enzymolysis tank and performing shearing to obtain slurry; filtering the slurry, then pumping the filtered slurry into the cooking and enzymolysis tank, adding composite neutral protease consisting of thiol protease-series bromelain, papain and Bacillus subtilis-produced neutral protease, and carrying out enzymolysis under a heat-preserved condition; and subjecting an enzymolysisproduct to post-treatment to obtain a finished sea cucumber peptide product. With the method in the invention, harmful heavy metals in a sea cucumber raw material can be completely removed; small-molecular peptide with a molecular weight of 1000 D or below in the enzymolysis product accounts for 85% or more; and the finished product has no fishy and peculiar smell.

The invention discloses a method for producing products such as soybean germ oil, soybean germ protein concentrate, soybean oligosaccharides, soybean saponins and soybean isoflavones by using soybean germs, and relates to the field of deep grain processing. The method comprises the following steps of: performing online stabilization treatment on the soybean germs; performing normal temperature extraction and low temperature desolventizing by taking subcritical fluid as a lytic enzyme to produce the soybean germ oil; extracting polar ingredients such as the soybean oligosaccharides and the like from the defatted soybean germs by taking subcritical liquid ammonia and the like as lytic enzymes, and separating the oligosaccharides, the isoflavones and the saponins from the extract and purifying; and separating the soybean germ protein concentrate from the liquid ammonia extract, namely a low temperature soybean gear meal. When the method is used, five products such as the germ oil, the oligosaccharides, the soybean protein concentrate and the like can be obtained simultaneously, so that the full utilization of the soybean germs is realized, and production cost is low; reextraction can be completed in different extraction stages of the same leaching equipment, so that investment is saved; and zero emission is realized, so that the method is environmentally-friendly.

The invention provides a preparation process of a fish scale collagen protein. With the preparation process, the collagen protein can be extracted from fish scales, so that the fish scales are changed into things of value from waste material and thorough utilization of resources is realized. The preparation process comprises the following steps of pretreating, decalcifying, neutralizing and removing impurity, washing by using water, sol, solid-liquid separating and filtering, hydrolyzing, filtering and separating the collagen protein, filtering and separating the macromolecular protein, desalting, dehydrating, drying and the like to obtain collagen protein powder. The collagen protein powder prepared by the preparation process has the molecular weight of less than 5000 Daltons and can be absorbed by the human body easily.

The invention belongs to the technical field of temperature-displaying utensils, and specifically relates to a temperature-displaying utensil and a manufacturing method that can display temperature or change printed patterns as the temperature changes. The container body is covered with a printing layer on the surface of the container, the printing layer is a temperature-sensitive ink layer, and the temperature-sensitive ink layer includes more than one group, and one group of temperature-sensitive ink layers includes the pattern layer on the bottom layer and the covering layer Layer, the pattern layer and cover layer of the same group have the same color; when the patterns and / or characters of the cover layer develop color, completely cover or hide the patterns and / or characters of the same group of pattern layers; cover in the same group of temperature-sensitive ink layers The achromatic point of the layer is lower than that of the pattern layer; except for the pattern layer adjacent to the container, the temperature-sensitive ink layer whose temperature is higher than the achromatic point is transparent or translucent, and can be used according to the color of the container. The display of printed patterns or characters or numbers, and a clear understanding of the temperature of the liquid in the vessel bring great convenience to use.

The invention belongs to the technical field of feeding bottles, and specifically relates to a temperature display feeding bottle and a manufacturing method that can display temperature or change printed graphics as the temperature changes. The bottle body is covered with a printing layer on the surface of the bottle body. The printing layer is a temperature-sensitive ink layer. The temperature-sensitive ink layer includes more than one group. A group of temperature-sensitive ink layers includes the bottom pattern layer and the pattern layer above the pattern layer. Covering layer, the color of the pattern layer and covering layer of the same group is the same; when the patterns and / or characters of the covering layer are colored, they completely cover or hide the patterns and / or characters of the same group of pattern layers; in the same group of temperature-sensitive ink layers The achromatic point of the covering layer is lower than that of the pattern layer; except for the pattern layer adjacent to the bottle body, the temperature-sensitive ink layer whose temperature is higher than the achromatic point is transparent or translucent, and can be based on The display of printed patterns or characters or numbers on the feeding bottle provides a clear understanding of the temperature of the liquid in the feeding bottle, which brings great convenience to use.
