Embodiment 1

[0026] (1), picking: picking fresh broad beans, selecting broad beans without mildew, insect damage, and no mechanical damage;

[0027] (2), soaking and cleaning: immerse the above-mentioned broad beans picked in ultrapure water, remove impurities and dust on the surface of the broad beans, and then sonicate for 1.5 hours;

[0028] (3), draining, air-flow blowing and mixing treatment: quickly drain the broad beans after super-treatment at a low temperature of 15°C in the dark, and then dry them for 30 minutes at 40°C with a mesh-belt type airflow dryer;

[0029] (4) High-pressure osmosis treatment: add 10ml mugwort essential oil into the heating chamber, promote the volatilization of mugwort essential oil at a constant temperature of 100°C, and use a high-pressure pump to pump the volatilized mugwort gas into the high-pressure air chamber containing 100g red dates , and pressurize the high-pressure air chamber to ensure that the pressure in the high-pressure air chamber is 9MP...

Embodiment 2

[0034] (1), picking: picking fresh broad beans, selecting broad beans without mildew, insect damage, and no mechanical damage;

[0035] (2), soaking and cleaning: immerse the above-mentioned broad beans picked in ultrapure water, remove impurities and dust on the surface of the broad beans, and then sonicate for 2 hours;

[0036] (3), draining, air blowing and mixing treatment: quickly drain the treated broad beans in the dark at a low temperature of 25°C, and then dry them for 50min at 60°C with a mesh belt type airflow dryer;

[0037](4) High-pressure osmosis treatment: add 15ml mugwort essential oil into the heating chamber, promote the volatilization of mugwort essential oil at a constant temperature of 100°C, and use a high-pressure pump to pump the volatilized mugwort gas into the high-pressure air chamber containing 100g red dates , and pressurize the high-pressure air chamber to ensure that the pressure in the high-pressure air chamber is 14MPa. At this time, the gas o...

Embodiment 3

[0042] (1), picking: picking fresh broad beans, selecting broad beans without mildew, insect damage, and no mechanical damage;

[0043] (2), soaking and cleaning: immerse the broad beans picked above in ultrapure water to remove impurities and dust on the surface of the broad beans, and then ultrasonically for 1.8h;

[0044] (3), draining, air blowing and mixing treatment: quickly drain the treated broad beans in the dark at a low temperature of 20°C, and then dry them for 40min at 50°C with a mesh belt type airflow dryer;

[0045] (4) High-pressure osmosis treatment: add 13ml mugwort essential oil into the heating chamber, promote the volatilization of mugwort essential oil at a constant temperature of 110°C, and use a high-pressure pump to pump the volatilized mugwort gas into the high-pressure air chamber containing 100g red dates , and pressurize the high-pressure air chamber to ensure that the pressure in the high-pressure air chamber is 12MPa. At this time, the gas of mu...

Abstract

The invention discloses a physical fresh-keeping method for broad beans and solves the problems of insect attack, low nutritional value and the like on broad beans during storage in the prior art. In the technical scheme, the method includes the steps of: soaking and cleaning fresh broad beans, draining the broad beans, performing high-pressure permeation treatment and vacuum high-voltage electric field corona discharge treatment, and vacuum-packaging and refrigerating the broad beans. In the invention, volatilized artemisia argyi gas shows an approximate supercritical status under a high pressure, wherein the gas has very strong permeation capability and can permeate in the interior of the broad beans, thereby achieving effective antibacterial and insecticidal function. Through the vacuum high-voltage electric field corona discharge treatment, the molecular structure of volatile components in the artemisia argyi is damaged, thereby further removing odors. Through the treatment, fresh-keeping period of the broad beans is greatly prolonged, and the broad beans have excellent color, smell and taste.

Description

technical field [0001] The invention belongs to the field of food preservation, and in particular relates to a physical preservation method of broad beans. Background technique [0002] Broad bean (Vetacea), also known as Luohan bean, Hudou bean, South bean, vertical bean, Buddha bean, Fabaceae, and Vetacea are annual herbs. Tender broad beans can benefit Qi and strengthen the spleen, dampness and swelling. In addition, it is rich in nutrients. Every 100 grams of broad beans contains 9 grams of protein and 19 grams of carbohydrates. It is also rich in dietary fiber, calcium, phosphorus, potassium, vitamin B, carotene and other healthy nutrients. The protein in tender broad beans is second only to soybeans in various beans. It also contains phospholipids, an important component of brain and nervous tissue, and rich in choline, which can enhance memory and strengthen the brain. In addition, broad beans are low-calorie foods, which are high-quality green foods for patients w...
