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.
