Embodiment Construction

[0006] Below in conjunction with embodiment the invention is given in specific description.

[0007] The process steps of the embodiment of the present invention are as follows: (1) remove the core from the picked lotus seeds through the core treatment process; (2) prepare the soaking solution according to the following proportions: disodium edetate 0.02-0.15%, vitamin C0 .1-0.3%, and the balance is water; (3) soaking the lotus seeds in step (1) through the soaking solution of step (2); (4) freezing after cleaning to make the lotus seeds internal moisture Ice crystallization; (5) Vacuum low-temperature sublimation drying: the lotus seeds obtained by step (4) in which the water in the body is ice-crystallized are placed in a vacuum low-temperature state, so that the water is directly sublimated into gas and evaporated.

[0008] In the most preferred embodiment of the present invention (1) prepare the soaking solution according to the following proportions: 0.1% disodium edetate...

Abstract

A freeze-dried lotus seed is prpared through removing core from lotus seeds, preparing liquid from Na2EDTA (0.02-0.15%), VC (0.1-0.3%) and water (rest), immersing the lotus seed in the liquid, washing, freezing and drying by low-temp vacuum sublimation. Its advantages are easily cooked soft and good taste.

Description

technical field [0001] The invention relates to a production process of freeze-dried lotus. Background technique [0002] Jianlian is a high-quality product produced in Jianning County, Fujian Province, with an annual export value of about 4 million US dollars, most of which are dried lotus seeds, which are mainly sold to Hong Kong, Macao, Taiwan, Japan and Southeast Asia. For a long time, the production process of dried lotus is to pick fresh lotus seeds and dry them in the sun. Because the technical parameters of the drying process cannot be mastered, the quality of the dried lotus produced is uneven. The main disadvantages are that the surface shrinks, and the rehydration is poor, the appearance is dark, the product is not easy to cook, and loses its fragrance and delicious essence. There are obvious differences in the flavor quality of fresh lotus. Contents of the invention [0003] The purpose of the present invention is to provide a production process of freeze-dri...
