Abstract

The invention discloses a box-packed bean curd. The box-packed bean curd is made from 11-14 baume degrees of soybean milk and 3-5% by soybean milk mass of a composite coagulator water solution, wherein the composite coagulator water solution is prepared by mixing a composite coagulator and water according to the mass ratio of 1:2-4, the composite coagulator is prepared from, by mass, calcium sulfate 65-75%, glucolactone 20-30%, magnesium chloride 2-5%, and the sum of the components is 100%. The box-packed bean curd is hygienic and safe, good in toughness, stable in quality and convenient to store and transport, has a fine and smooth taste, is not tender after long-time boiling and is suitable for long-distance sales. The invention further provides a processing technology of the box-packed bean curd. The processing technology comprises the steps of material selection, soaking, cleaning, pulping, pulp screening, pulp flushing and the like, is simple in process step, good in operability and low in production cost and is suitable for industrialized large-scale production.

Description

technical field [0001] The invention relates to a kind of tofu, in particular to a kind of boxed tofu and its processing technology. Background technique [0002] Tofu is a food with soybeans as the main raw material.
