Abstract

The invention discloses a processing method of ready-to-eat freeze-dried daylily. According to the processing method, daylily can be prevented from bud scattering and blooming when the daylily is subjected to blanching and enzyme deactivation, the daylily can be seasoned while blanching and enzyme deactivation are performed, and therefore the process is simple and convenient. A daylily product processed by the method is a ready-to-eat product, is crisp in taste, is convenient to eat, can be used as tourism food and leisure food, and meets different consumption requirements.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to an instant freeze-dried daylily and a processing method thereof.
