Embodiment 1

[0007] Embodiment 1, (1) Cleaning of raw materials: wash 10 kg of fresh selenium-enriched asparagus with water to remove sediment; at this time, set the preservation rate of selenium in asparagus to 100%; (2) Finishing: wash the selenium-enriched asparagus in Soak in water at 98°C for 3 minutes. Since the selenium in asparagus exists in the form of organic selenium, as a macromolecular organic selenium, it is unstable at high temperature and is easy to lose at high temperature. Therefore, how to effectively reduce the selenium in the high temperature environment in the production process The loss of selenium requires accurate test determination. After testing, the preservation rate of 10kg selenium at this time is 76.5%, so the preservation rate of selenium in asparagus is relatively ideal at this time; (3) Cut into sections: the selenium-enriched asparagus after cooling Cut into sections with a length of 4-5 cm; (4) Tasting: put the selenium-enriched asparagus in the pre-prepa...

Embodiment 2

[0008] Embodiment 2, (1) Cleaning of raw materials: Wash 5 kg of fresh selenium-enriched asparagus with water to remove sediment; at this time, the preservation rate of selenium in asparagus is set to 100%; (2) Finishing: wash the selenium-enriched asparagus in Soak in water at 96°C for 2.5 minutes. After testing, the average preservation rate of 5kg of selenium is 79%, so the preservation rate of selenium in asparagus is ideal at this time; (3) Cut into sections: cut the cooled selenium-enriched asparagus into sections , the length is controlled at 4-5 cm; (4) Flavoring: put the selenium-enriched asparagus cut into sections in the seasoning liquid prepared in advance, and vacuum flavoring, the vacuum degree is 0.08MPa, and the flavoring time is 10 minutes, so that the seasoning (5) Freeze-drying: pre-freeze the selenium-enriched asparagus at -35°C for 2 hours, then sublimate and dry for 10 hours, control the thawing and drying temperature at 40°C, and dry until it is crispy; (...

Embodiment 3

[0009] Embodiment 3, (1) Cleaning of raw materials: Wash 15 kg of fresh selenium-enriched asparagus with water to remove sediment; at this time, set the preservation rate of selenium in asparagus to 100%; (2) Finishing: wash the selenium-enriched asparagus in Soak in water at 100°C for 4 minutes. After testing, the preservation rate of 15kg of selenium at this time is 64.4%, so the preservation rate of selenium in asparagus is ideal at this time; (3) Cut into sections: cut the cooled selenium-enriched asparagus into sections, The length is controlled at 4-5 cm; (4) Flavoring: Put the selenium-enriched asparagus in the pre-prepared seasoning liquid, and carry out vacuum flavoring, the vacuum degree is 0.08MPa, and the flavoring time is 10 minutes, so that the seasoning liquid Infiltrate as much as possible; (5) Freeze-drying: pre-freeze the selenium-enriched asparagus at -35°C for 2 hours, then sublimate and dry for 10 hours, control the thawing and drying temperature at 40°C, a...

Abstract

The invention relates to a processing method of selenium-rich convenient instant dry asparagus. The processing method comprises the following steps that (1) raw material cleaning: fresh selenium-rich asparagus is cleaned by water; (2) enzyme deactivation: the fresh selenium-rich asparagus is soaked for 2 to 4 minutes in water being 95 to 100 DEG C; (3) segment cutting: the cooled fresh selenium-rich asparagus is subjected to segment cutting, and the length is controlled to be 4 to 5cm; (4) flavor enhancing: the selenium-rich asparagus subjected to segment cutting is placed into prepared seasoning liquid for vacuum flavor enhancing, the vacuum degree is 0.08MPa, and the flavor enhancing time is 10 minutes; (5) freeze drying: the selenium-rich asparagus subjected to the flavor enhancing is firstly frozen for 2 hours at -35 DEG C, then, the sublimation drying is carried out for 10 hours, the unfreezing drying temperature is controlled at 40 DEG C, and the drying is carried out until the selenium-rich asparagus is fragrant and crispy; (6) detection: the selenium content and the moisture content of the dry asparagus are detected; and (7) package. The dry asparagus processed by the processing method provided by the invention has the advantages that the content of the organic selenium is high, and in addition, the eating is convenient.

Description

technical field [0001] The invention relates to a processing method of selenium-enriched convenient instant dried asparagus. Background technique [0002] As we all know, selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans. It plays a role in balancing the redox atmosphere in the body. Studies have shown that it can improve animal immunity Therefore, selenium is an essential trace element for the human body. At present, the adult intake recommended by the Chinese Nutrition Society is 50-250 micrograms per day, while the selenium intake in two-thirds of China is lower than the minimum recommended value. According to statistics, the entire Selenium is deficient in 42 countries and regions in the world, and 72% of China is in a selenium-deficient or low-selenium ecological environment. It has been determined that some diseases, especially tumors, hypertension, endocrine and metabolic diseases, dia...
