Problems solved by technology

[0004] The existing lily scale ball processing technology is relatively simple, mostly limited to hot air high-temperature drying or natural drying, resulting in the loss of nutrients during processing, the inactivation and loss of biologically active substances contained in them, and various degrees of loss in shape, color, and properties. The processed products have disadvantages such as non-instantaneity, poor rehydration, stiff taste, and inconvenient consumption.

preparation example Construction

[0015] A kind of preparation technology of lily freeze-dried sheet, comprises the following steps:

[0016] (1) Pretreatment: including a blanching, b first-stage water cooling, c second-stage water cooling, d air cooling, and e code disc in sequence.

[0017] It should be noted that, in this embodiment, before blanching in a, it also includes: peeling, grading and cleaning; wherein, the peeling and grading includes: after removing the roots and mud of the lily scales, peeling the lily scales from the outside to the inside. In order to facilitate the arrangement and packaging of the final product, the individual pieces are graded according to size; due to the heat generation and heat dissipation of the lily itself, the temperature of the lily itself is relatively high, especially in spring, when the lily has a strong metabolism and is prone to deterioration and rot. The scales are cooled. Considering the reduction of production cost, in this embodiment, the method of cleaning ...

Embodiment 1

[0029] The present embodiment provides a kind of preparation technology of lily freeze-dried sheet, comprising:

[0030] (1) Preprocessing:

[0031] a blanching: blanching the lily scales at 70°C for 15 minutes;

[0032] b The first stage of water cooling: put the lily scales in 30°C water to cool for 10 minutes;

[0033] c The second stage of water cooling: put the lily scales in 10°C water to cool for 10 minutes;

[0034] d Air cooling: dry the lily scales until there is no flowing water on the surface;

[0035] e code plate: stack dried lilies with a thickness of 5cm;

[0036] (2) Freeze drying:

[0037] a Pre-freezing: Place the stacked lily scales in the freezing cabin, drop the temperature in the freezing cabin to -30°C at a rate of 0.1°C / min, then drop to -45°C at a rate of 0.3°C / min, When the cold hydrazine temperature reaches -45°C, keep the cold hydrazine temperature for 3 hours;

[0038] b The first stage of drying: the first temperature rise: control the vacu...

Embodiment 2

[0042] This example provides a preparation process for lily freeze-dried flakes, which differs from Example 1 in that: a) blanching: blanching lily scales at 90° C. for 3 minutes.

Abstract

The invention belongs to the technical field of food processing and provides a lily freeze-dried tablet and a preparation process thereof. The preparation process mainly includes: (1) pretreatment: a blanching; b first stage water cooling; c second stage water cooling; e code plate; (2) freeze drying: a pre-freezing; b first stage drying; Two-stage drying. The preparation process is scientifically designed and can realize large-scale industrial production. The prepared freeze-dried lily flakes can retain the original shape, nutrition and color of the lily to the greatest extent, have good rehydration properties, and are convenient to eat. The taste is crisp and ready to eat. And easy to store and transport.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a lily freeze-dried sheet and a preparation process thereof. Background technique [0002] Lily, also known as Qiangshu, Fanjiu, Shandan, Daoxian, Chongmai, Zhongting, Moro, Zhongfeng, Zhongfenghua, Lily Garlic, Master Garlic, Garlic Brain Potato, Nocturnal Lily, etc., is a lily of the Liliaceae family. It is a perennial herbaceous bulbous plant, native to China, mainly distributed in the temperate regions of the northern hemisphere such as eastern Asia, Europe, and North America. At least 120 species have been found in the world, 55 of which are produced in China. Lily bulbs are rich in starch, edible and also used as medicine. [0003] Lily scales contain saponins, alkaloids, polysaccharides, phospholipids, proteins, vitamins, starch and a large number of trace elements, which have rich nutritional value and special health effects. It can increase blood ce...
