Embodiment 1
[0053] Example 1: Ultrasonic treatment in conjunction with gibberellin acetate combined with modified atmosphere packaging
[0054] (1) Select high-grade asparagus with a stem length of 25cm, a diameter of 16-18mm, no bending, no mechanical damage, abrasion and rot;
[0055] (2) Ultrasonic treatment of the high-grade asparagus selected in step (1), immersing the asparagus in an ultrasonic generator containing water, the ultrasonic power is 360W, the ultrasonic time is 10min, taken out, and drained;
[0056] (3) step (2) is soaked in the composite antistaling agent of acetic acid and gibberellin through the high-grade asparagus of step (2) supersonic treatment, described per L antistaling agent, acetic acid concentration is adjusted to be 20mL / L, gibberellin concentration is 50mg / L, soak for 10min, then take out and drain quickly;
[0057] (4) the asparagus obtained by step (3) is processed, and the modified atmosphere packaging machine is used to carry out the modified atmosphe...
Embodiment 2
[0059] Example 2: Ultrasonic treatment and 1-methylcyclopropene combined with modified atmosphere packaging
[0060] (1) Select high-grade asparagus with a stem length of 25cm, a diameter of 16-18mm, no bending, no mechanical damage, abrasion and rot;
[0061] (2) Ultrasonic treatment of the high-grade asparagus selected in step (1), immersing the asparagus in an ultrasonic generator containing water, the ultrasonic power is 360W, the ultrasonic time is 10min, taken out, and drained;
[0062] (3) Use 1-methylcyclopropene at a mass concentration of 0.002% to 0.02% for the high-grade asparagus that has been ultrasonically treated in step (2), and fumigate for 24 hours;
[0063] (4) the asparagus obtained by step (3) is processed, and the modified atmosphere packaging machine is used to carry out the modified atmosphere packaging, and the gas composition is O 2 5%, CO 2 10% and N 2 85%, packed in low-density polyethylene antibacterial fresh-keeping bags, the thickness of the l...
Embodiment 3
[0065] Embodiment 3: the selection of ultrasonic condition
[0066] 1. Selection of ultrasonic power:
[0067] Referring to the method of Example 2 to process asparagus, the only difference is that the ultrasonic power is adjusted to 100W and 360W, and other parameter conditions are the same as in Example 2. On the 40th day of storage of asparagus, the number of microorganisms on the surface and the nutritional quality are shown in Table 1.
[0068] 2. Selection of ultrasonic time:
[0069] Referring to the method of Example 2 to process asparagus, the only difference is that the ultrasonic time is adjusted to 5, 10, and 15 minutes, and other parameter conditions are the same as in Example 2. On the 40th day of storage of asparagus, the number of microorganisms on the surface and the nutritional quality are shown in Table 1.
