The invention discloses a preservation method of fresh-
cut edible fungi. The preservation method mainly includes following steps: using
brassinolide to pretreat edible fungi, pre-cooling, and
slicing to obtain
fungus pieces; sinking the
fungus pieces in
electrolysis water for ultrasonic cleaning for 3-5 min, wherein pH value of the
electrolysis water is 5-6.5, and effective
chlorine concentration is 10-30 mg / g; using
ultraviolet rays to irradiate the surfaces of the
fungus pieces after being cleaned, wherein
wavelength of the
ultraviolet rays is 240-260 nm, and
irradiation dosage is 1-3 kJ / m2; encapsulating, and refrigerating. The fresh-
cut edible fungi are subjected to
electrolysis water, ultrasonic and
ultraviolet ray combined preservation treatment, surface microorganisms can be killed more thoroughly, rotting rate of the fresh-
cut edible fungi is lowered effectively,
browning degree is reduced,
nutritional quality and sensory quality of the fresh-cut edible fungi are better maintained,
shelf life of the fresh-cut edible fungi is prolonged effectively, and especially for fresh-cut
Agaricus bisporus, the
shelf life can be prolonged from 1-2 days to 10-12 days at normal temperature.
