Blueberry and blackberry juice solidified bean curd and production method thereof

Abstract

The invention discloses a blueberry and blackberry juice solidified bean curd and a production method thereof, wherein the method comprises the steps: firstly, removing impurities from soybeans, cleaning, soaking with water until no solid, grinding into thick liquid, separating bean dregs to obtain raw soybean milk, and heating the raw soybean milk to obtain cooked soybean milk; and selecting ripe and fresh blueberries, crushing to obtain whole blueberry juice, or centrifuging or filtering to obtain clear blueberry juice, diluting the whole blueberry juice or clear blueberry juice with water, heating, adding to the end point of soybean milk by using a sectional curdling method, standing, pouring into a mold, and carrying out compression molding to obtain the blueberry solidified bean curd. According to the production method for coagulation production of the blueberry solidified bean curd with the whole blueberry juice or clear blueberry juice as the coagulant, the obtained blueberry solidified bean curd is rich in fruity flavor and rich in anthocyanin, the nutrition and health care functions are greatly improved, an existing bean curd production line does not need to be transformed, the construction cost of the production line is low, and the method is suitable for large-scale industrial production and small workshop production, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of deep processing of bean products, and in particular relates to coagulated tofu with blueberry and blackberry juice and a production method thereof. Background technique [0002] Tofu contains 8 kinds of essential amino acids needed by the human body, and has the nutritional characteristics of high protein and low cholesterol. Regular consumption of tofu can reduce the content of cholesterol in the blood and reduce the chance of arteriosclerosis. It is also beneficial to people with neurasthenia and weak constitution. It has great benefits, and has a certain auxiliary curative effect on patients with hypertension and coronary heart disease during the treatment process. Therefore, bean curd is nutritious and has certain health-care effect to human body, and this characteristic is subjected to the great attention of people and becomes the delicacy on people's dining table at home and abroad. Coagulants for tofu produ...

Problems solved by technology

[0005] Purpose of the invention: Aiming at the deficiencies in the prior art, the present invention provides a coagulated tofu with berry juice and its production method, which solves the risk of chemical residues in traditional tofu production using chemical coagulants or the existence of naturally fermented yellow pulp water as a coagulant Biosafety risks, the problem of single product variety and taste and flavor, and when berry juice is used as a natural coagulant because it contains a large amount of organic acids and anthocyanins at the same time, the behavior of inducing soybean protein coagulation is different from that of ordinary acid coagulants. The technology of producing tofu with acid coagulants is analogized to the production of coagulated tofu with blueberry and blackberry juice, focusing on solving the problems that blueberry and blackberry juice, as a natural coagulant, will cause uneven coagulation of soybean protein, resulting in uneven texture of tofu and reduced yield.
