Embodiment 1

[0021] Example 1: A soft-packaged water celery green preservation and crispness processing method, using fresh water celery as raw material, through pretreatment, blanching color protection, cooling, crispness preservation, auxiliary material conditioning, vacuum sealing, sterilization, cooling, and finally finished products , The steps are as follows:

[0022] (1) Raw material selection: Choose fresh, undamaged cress as raw material.

[0023] (2) Pretreatment: Cut off the roots and leaves, wash away the surface sediment and impurities with water, and cut into 2-3cm long sections.

[0024] (3) Blanching color protection: Put the water celery in Cu at 95℃ 2+ And Zn 2+ The concentration of the mixed solution is 200 / 50mg·kg -1 Blanch in the color protection solution for 2 minutes.

[0025] (4) Cooling: Cool with water at 15°C for 3 minutes.

[0026] (5) Keep crisp: After cooling, put the water celery in a certain concentration of 0.2% CaCl 2 Soak in the solution for 20 minutes, then rinse...

Embodiment 2

[0031] Example 2: The rest is the same as Example 1, except that in step (3), the cress is placed in Cu at 100°C. 2+ And Zn 2+ The concentration of the mixed solution is 200 / 50mg·kg -1 Blanch in the color protection solution for 2 minutes; in step (5), put the cooled water celery in a certain concentration of 0.3% CaCl 2 Soak in the solution for 20 minutes, then rinse and drain with water; in step (7), the vacuum-sealed cress is placed in a 100°C water bath for sterilization for 9 minutes.

Embodiment 3

[0032] Example 3: The rest is the same as Example 1, except that in step (3), the cress is placed in Cu at 100°C. 2+ And Zn 2+ The concentration of the mixed solution is 200 / 50mg·kg -1 Blanch in the color protection solution for 3 minutes; in step (5), the cooled water celery is placed in a certain concentration of 0.3% CaCl 2 Soak in the solution for 20 minutes, then rinse and drain; in step (6), mix the seasoning with water celery in a certain proportion, the seasoning includes salt, MSG, compound spices, vegetable oil, sesame oil and other seasonings, and then add 0.15% lemon Acid to pH 4.4, mix well, put it into a cooking bag, and vacuum seal; in step (7), the vacuum-sealed water celery is sterilized in a 100°C water bath for 10 minutes.

[0033] After the above steps, to be tested:

[0034]

[0035] Based on the above: the soft-packaged cress product produced by this method has bright green color, clear soup, stable storage, and the unique aroma and taste of cress. The crude fi...

Abstract

The invention discloses a processing method for retaining green color and crispiness of flexibly-packaged water celery, and belongs to the field of food preservation. The processing method comprises the following steps: with fresh water celery as a raw material, pretreating, retaining the color by blanching, cooling, retaining the crispiness, conditioning by using auxiliary materials, performing vacuum sealing, sterilizing, cooling and finally processing into a finished product. The flexibly-packaged water celery product processed by the processing method does not change too much in color and luster in the storage process, has a fresh green color and clear juice, and is stable in storage, rich in nutrition and safe to eat.

Description

Technical field [0001] The invention relates to the field of food preservation and processing. Specifically, the invention relates to a processing method for protecting the green and crispness of soft-packaged cress. Background technique [0002] Cress is a perennial aquatic perennial herb. It is one of the important types of special aquatic vegetables in China. It can clean blood, lower blood pressure and blood lipids when eaten regularly, so it is very popular among people. However, the color and quality of green vegetables during processing and storage The structure often changes. Because the green chlorophyll is very unstable, it is easy to produce pheophytin, and the color of vegetables becomes yellow or even brown, which greatly affects the product quality. Summary of the invention [0003] The present invention provides a soft-packaged water celery green and crisp processing method to solve the problem that the color and texture often change during the processing and storag...
