Abstract

A preparation method of konjac glucomannan edible tableware comprises preparing esterification modified products, preparing composite gel, heating, centrifugally degassing, shaping tableware, samming and easing back, and sterilizing. The viscosity, film formation temperature and gel strength of konjac glucomannan sol-gel are easy to control, thereby greatly improving the performance and stability of industrial production. The konjac glucomannan edible tableware makes up the defect in the aspect of quality control of products; and the sensory quality of the konjac glucomannan edible tableware is greatly improved. Furthermore, the main raw material konjac glucomannan adopted in the invention is low in price, thereby not only improving the safety of tatableware but also greatly reducing the production cost of products. The konjac glucomannan edible tableware is a water-resistant and high-temperature resistant edible tableware.

Description

technical field

[0001] The invention relates to an edible tableware and a preparation method thereof, in particular to a konjac glucomannan edible tableware and a preparation method thereof. Background technique

[0002] For a long time, disposable high-foaming plastic tableware with polystyrene as the main raw material has provided many conveniences for people's lives. However, polystyrene is difficult to recycle, incineration produces harmful gases, buried in the ground is not easy to rot, and it affects farmland cultivation, destroys soil structure, and causes serious pollution to the environment. From the perspective of long-term interests, "white pollution" will cause serious damage to the living environment of human beings. Therefore, eliminating "white pollution" has become a major global problem. State Economic and Trade Commission (1999) No. 6 clearly stipulates that the use of disposable foam plastic tableware will be completely banned nationwide before the end of...
