Methods for making a plant-based food product from a microalgae are described. An example method includes obtaining a microalgae, extracting chlorella protein from the microalgae, modifying a factor associated with the chlorella protein and/or adding a stimulant to the chlorella protein to change an amino acid combination of the chlorella protein, and utilizing the modified chlorella protein as a protein flour to create the plant-based food product.

Methods to extract chlorella protein from algae powder are described. A first extraction method is an alkaline solution extraction method. A second extraction method is an enzyme extraction method. A third method is a low-temperature deep eutectic solvents (DES) extraction method. According to each of these methods, a protein recovery rate is calculated from a protein extract solution of chlorella protein.

A method for preparing IPP- and VPP-rich hydrolysate from wheat gluten protein by enzymatic hydrolysis is disclosed, comprising the following steps: (1) dissolving wheat gluten protein in an alkaline solution, and performing ultrasonic treatment; (2) adding the alkaline protease to the wheat gluten protein solution to hydrolyze; (3) adjusting the pH value of the alkaline hydrolysate to neutral or weakly acidic, and adding protease to hydrolyze, and inactivating the enzyme at a high temperature; (4) centrifuging the hydrolysate to obtain the supernatant, and ultrafiltrating with an ultrafiltration membrane; (5) decolorizing and debitterizing the permeate using a macroporous resin; (6) after the debittered and decolorized liquid is adsorbed by an ion exchange resin, eluting the ion exchange resin and drying, to obtain a powder of IPP- and VPP-rich hydrolysate. The preparation method has a high protein recovery rate, with rich IPP and VPP in the hydrolysate.

A composition and method of preparing a corn protein hydrolysate includes obtaining a corn protein composition having a corn protein concentration of at least about 75 wt %, adding an enzyme to a corn protein suspension containing the corn protein composition at a ratio of from about 1:100 to about 1:20 by weight of enzyme to corn protein, controlling the pH and temperature of the corn protein suspension to hydrolyze the corn protein, and terminating the hydrolysis of the corn protein to provide a corn protein hydrolysate that has solubility of from about 7% to about 37% at a pH selected from the group consisting of pH 7.0, pH 3.4, pH 5, and all of pH 7.0, pH 5, and pH 3.4. The corn protein hydrolysate can be used in a variety of food, feed, beverage, and other applications.

The present invention relates to a method for producing a protein hydrolysate using a polypeptide having endopeptidase activity and a polypeptide having carboxypeptidase activity and the use of these enzymes for hydrolysing a protein substrate. In addition, the present invention relates to polypeptides having carboxypeptidase activity and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

The present disclosure disclosed is a method for reducing the purine content of soybean milk, which belongs to the technical field of food depurination. According to the method, purine-reducing soybeans are taken as raw materials, and macromolecular purine in a bound state is selected to be hydrolyzed into small molecules according to different existence forms of purine in soybeans, and then micromolecular purine is adsorbed and removed by an adsorbent. The method is high in feasibility and good in removal effect. The soybean milk of the present disclosure is safe and non-toxic, high in purine removal rate, and low in nutrient loss, has no obvious change in mouth feel compared with common soybean milk, and can be used as a safe food for gout patients.

Provided are non-dairy yogurt analogs that have qualities similar to those of dairy-based yogurts. Certain embodiments are to plant-based yogurt analogs comprising fermented plant protein isolates and/or gelled plant protein isolates. Also provided are processes for production of such non-dairy yogurt analogs. For instance, a method for producing a plant-based yogurt mixture capable of being used to make a plant-based yogurt analog comprising the steps of: a) obtaining an essentially dairy-free base for a yogurt formulation that includes a plant-based derivative, such as a paste; and b) adding an acid to said formulation. Thereafter, the plant-based yogurt formulation may be used to manufacture a plant-based yogurt analog comprising the steps of: a) heating a plant-based yogurt mixture for a first pre-determined amount of time while stirring; b) allowing the mixture to cool; c) adding yogurt cultures to the resultant mixture; and d) incubating the resultant mixture for a second pre-determined amount of time to produce a plant-based yogurt analog.
