Novel technologies for improving quality of tofu products and their packaging: A critical overview

There are many kinds of tofu products, and they are mainly found in Asia. This paper mainly summarizes and classifies the tofu products of different countries through the analysis of the characteristics of different products and the differences between them. The storage conditions for most bean products are typically harsh, resulting in the shelf life of some fresh beans limited to 3–5 days. The new packaging technology avoids the shortcomings of traditional packaging, which makes it more effective to store. In this paper, biodegradable packaging materials, nanomaterials, active packaging, and intelligent packaging were reviewed. The significance of this review is to introduce various types of tofu products to gain a more comprehensive understanding of their advantages and disadvantages and to apply different packaging techniques to improve the preservation environment of tofu products. The purpose is to find suitable packaging technology, materials, and development route of tofu products.
