Embodiment 1

[0026] (1), raw material pretreatment: peel off the fresh lotus seeds from the lotus pod, remove the skin of the lotus seeds, and manually remove the lotus seeds with wormholes and mildew;

[0027] (2), soaking and cleaning: immerse the lotus seeds after the above treatment in ultra-pure water, remove impurities and dust on the surface of the lotus seeds, and then ultrasonic for 1 hour;

[0028] (3), draining, air-flow blowing and mixing treatment: the red dates after the treatment are kept away from light and drained quickly at a low temperature of 10°C, and then dried for 40min at 50°C with a mesh belt type airflow dryer;

[0029] (4) High-pressure osmosis treatment: Add 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 essential oil gas into the high-pressure air chamber containing lotus seeds , and pressurize the high-pressure a...

Embodiment 2

[0034] (1), raw material pretreatment: peel off the fresh lotus seeds from the lotus pod, remove the skin of the lotus seeds, and manually remove the lotus seeds with wormholes and mildew;

[0035] (2), soaking and cleaning: immerse the lotus seeds after the above treatment in ultra-pure water, remove impurities and dust on the surface of the lotus seeds, and then ultrasonic for 1 hour;

[0036] (3), draining, air-flow blowing and mixing treatment: the red dates after the treatment are kept away from light and drained quickly at a low temperature of 20°C, and then dried for 60min at 80°C with a mesh belt type airflow dryer;

[0037] (4) High-pressure osmosis treatment: Add mugwort essential oil into the heating chamber, promote the volatilization of mugwort essential oil at a constant temperature of 120°C, and use a high-pressure pump to pump the volatilized mugwort essential oil gas into the high-pressure air chamber containing lotus seeds , and pressurize the high-pressure air...

Embodiment 3

[0042] (1), raw material pretreatment: peel off the fresh lotus seeds from the lotus pod, remove the skin of the lotus seeds, and manually remove the lotus seeds with wormholes and mildew;

[0043] (2), soaking and cleaning: immerse the lotus seeds after the above treatment in ultra-pure water, remove impurities and dust on the surface of the lotus seeds, and then ultrasonic for 1 hour;

[0044] (3), draining, air blowing and mixing treatment: the treated lotus seeds are quickly drained at a low temperature of 15°C in the dark, and then dried for 50min at 65°C with a mesh belt type airflow dryer;

[0045] (4) High-pressure osmosis treatment: Add 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 essential oil gas into the high-pressure air chamber containing lotus seeds , and pressurize the high-pressure gas chamber to ensure that th...

Abstract

The invention discloses a physical preservation method of lotus seeds. The physical preservation method solves the problems of the pests and the low nutritional value of the lotus seeds in the existing storage process. The method comprises soaking and cleaning fresh lotus seeds, draining the lotus seeds, carrying out high-pressure penetration treatment, carrying out vacuum high voltage electric field corona discharge treatment, carrying out vacuum packaging and then carrying out refrigeration. The volatile Artemisia argyi gas is in an approximate supercritical state under high pressure, has very strong penetrability into lotus seeds and has effective antimicrobial and insecticidal effects. Through the vacuum high voltage electric field corona discharge treatment, the molecular structure of the volatile component of Artemisia argyi is broken and the odor is further removed. The storage period of the lotus seeds treated by the physical preservation method is greatly prolonged and color, fragrance and taste of the stored lotus seeds are kept.

Description

technical field [0001] The invention belongs to the field of food preservation, and in particular relates to a physical preservation method for lotus seeds. Background technique [0002] Lotus seed is the seed of lotus, an aquatic herbaceous plant of Nymphaeaceae. The content of calcium, phosphorus and potassium in lotus seeds is very rich. Each kilogram of lotus seeds contains 81.3 grams of protein, 9.8 grams of fat, 304 mg of sugar, 436 mg of calcium, 1.397 mg of phosphorus, 31.4 mg of iron, and other vitamins and trace elements Nuciferine, hypericin, lotus seeds and other substances, in addition to the components that can form bones and teeth, also have the effect of promoting blood coagulation, activating certain enzymes, maintaining nerve conduction, calming nerves, maintaining muscle elasticity and heartbeat Rhythm etc. Modern pharmacological research has also confirmed that lotus seeds have various effects such as calming, strengthening the heart, and anti-aging.
