A protein hydrolysate comprising at least two types of peptides, characterized in that the rate of hydrolysis of protein is from 30 to 45%, the number average molecular weight is 300 or less, and the ratio of a weight average molecular weight to the number average molecular weight is greater than 1 and 2 or less, has excellent emulsifiability, and antigenicity thereof is low enough to be used for people who has predisposition to allergic diseases. This protein hydrolysate is obtained by hydrolysis of a protein starting material to a rate of hydrolysis in the range of 30 to 45%, and then bringing it into contact simultaneously or separately with two types of porous synthetic adsorbent respectively having an average pore radius of 2 to 8 nm and an average pore radius of 20 to 30 nm, the total surface area of the two porous synthetic adsorbents being in a range of 300 to 3000 m2 per 1 g (protein equivalent) of the obtained protein hydrolysate, and recovering the non-adsorbed component.

The invention discloses a production process for cadmium-removed reproduced rice. Firstly, brown rice with the cadmium content of 0.2 mg/kg to 1.0 mg/kg is smashed into brown rice powder, then dissolution and centrifugal separation treatment are conducted, rice starch and rice protein are obtained and subjected to cadmium removal treatment, the cadmium-removed rice starch, the cadmium-removed rice protein and other nutrient substances are obtained, finally, mixing and extrusion pelleting treatment are conducted, and the cadmium-removed reproduced rice is obtained. The cadmium removal technology and the rice reproduction technology can be combined, the content of heavy metal cadmium in the rice is progressively reduced, the appearance of the rice is not affected, and the nutritional ingredients in the rice cannot be reduced.

Formulations comprising hydroxy methionine analog and having low levels of sulfate ions and bisulfate salts, processes for preparing the formulations, compositions comprising the formulations, and methods of using the formulations.

The method of the invention produces modified milk protein concentrates using cation exchange to replace divalent ions with monovalent ions. The modified milk protein concentrate produced may be converted into a gel which may be a cheese-like product itself, or used to make end products such as cheeses, cheese-like products, savory products, desserts, confectionary products and intermediate food products.

The invention relates to a method for obtaining a protein from a plant material, wherein the method comprises the steps of i) mechanically disrupting the plant cells to obtain a plant juice in the presence of a reducing agent, ii) treating the plant juice to cause aggregation of chloroplast membranes, iii) removing the aggregated chloroplast membranes by precipitation and/or microfiltration, iv) subjecting the plant juice to ultrafiltration, and v) subjecting the soluble plant protein concentrate to hydrophobic column adsorption to remove residual chlorophyll, phenolic compounds and off-odors in a single column passage. The present invention also pertains to an apparatus and system for plant protein isolation based on this method. The isolated proteins can be economically obtained in batch scale and in large scale. Further, the invention is directed to a protein obtained by the method of the invention, a food product comprising thereof, and a use thereof.

The invention discloses a preparation method for special syrup for caramel treats. The preparation method comprises the following steps: (1) performing chromatographic separation, namely pumping glucose mother liquor discharged after separating crystal glucose into a chromatographic separation system, performing chromatographic separation to prepare glucose AD liquor and glucose BD liquor, and taking the glucose AD liquor as a raw material for preparing the special syrup for the caramel treats; (2) performing ion exchange; (3) concentrating; (4) isomerizing, namely pumping concentrated liquor prepared in the step (3) into an isomerizing front tank; (5) mixing, namely mixing an isomerized material with the glucose BD liquor prepared in the step (1) to prepare mixed liquor; (6) decolorizing and filtering; (7) performing ion exchange; (8) concentrating to prepare the special syrup for the caramel treats. The glucose BD liquor retains maltose in the BD liquor in a preparation process of the special syrup for the caramel treats, so that the syrup has an aroma of malt; in addition, the syrup contains part of oligosaccharides and has a healthcare effect of multiplying good bacteria in human intestinal tract.

The present invention discloses a fumigation method used for preventing and curing grain pests and mildew. The method comprises the following steps: in an environment from room temperature to 40 DEG C, a fumigant is placed below or/and around grain piles; the fumigant is a compound having a chemical structure shown as a formula I in the description or a formula II in the description. The fumigation method realizes a safe and effective preventing and curing of common pest and mildew harms on the grains, is lowest in environmental pollution and has advantages of being green and environmentally protective.
