AI Technical Summary

Technical Problem

Traditional tofu production suffers from unstable yield, poor texture uniformity, and difficulty in controlling flavor. Existing technologies struggle to achieve a balance between high yield and high quality. Furthermore, the use of single coagulants or exogenous additives in traditional processes results in poor tofu texture or a bitter taste, failing to meet the health needs of modern consumers.

Method used

A standardized control method was adopted throughout the entire process, including the use of a compound brine coagulant (a two-step brine method of calcium sulfate and magnesium chloride) and a variable-temperature post-ripening process, combined with dynamic disturbance and efficient shearing, to prepare a standardized soybean protein slurry, and to form an excellent gel network structure through static and cold storage steps.

Benefits of technology

It achieves a balance between high yield and high quality, producing tofu with a delicate and uniform texture, no beany smell, high protein content, moderate moisture content, and a smooth and elastic cut surface, making it suitable for modern industrialization and meeting consumers' demand for high-quality soy products.

Abstract

本发明属于豆制品加工技术领域,公开了一种基于全流程标准化调控的高品质豆腐及其制备方法。本发明所述高品质豆腐使用原料特性筛选与精准磨浆技术,通过严格控制黄豆来源、泡豆时间、湿豆与水的比例及煮浆参数,调控了豆浆的固形物浓度与风味物质释放,有效钝化了脲酶并去除了挥发性豆腥味。本发明使用“硫酸钙‑氯化镁”双步点卤与动态扰动技术,利用复配凝固剂的协同效应与变温后熟工艺,构建了均匀致密的蛋白质凝胶网络。本发明制备得到的豆腐具有优异的持水性与质构特性,产品质地细腻、切面光滑;蛋白质含量≥8.0g / 100g,水分含量70%~85%,不仅实现了生产得率的标准化控制,且感官品质远高于传统粗放式加工产品,适合工业化推广。
