Embodiment 1

[0010] Dissolve 0.01g spermine and 0.1g L-cysteine ​​in 99.89g water to make a composite preservative for Agaricus bisporus. Wherein, the final concentration of spermine is 0.01%, and the final concentration of L-cysteine ​​is 0.1%.

Embodiment 2

[0012] Dissolve 0.02g spermine and 0.3g L-cysteine ​​in 99.68g water to make a composite preservative for Agaricus bisporus. Wherein, the final concentration of spermine is 0.02%, and the final concentration of L-cysteine ​​is 0.3%.

Embodiment 3

[0014] Dissolve 0.03g spermine and 0.5g L-cysteine ​​in 99.47g water to make a composite preservative for Agaricus bisporus. Wherein, the final concentration of spermine is 0.03%, and the final concentration of L-cysteine ​​is 0.5%.

[0015] The technique of applying the color-protecting and antistaling agent of the present invention to preserve the freshness of Agaricus bisporus is as follows: Agaricus bisporus is cut off the bottom culture, and the ClO of 5mg / L 2 Soak in the solution for 5 minutes, rinse, place in the color-protecting and antistaling agent of the present invention and immerse for 8 minutes, dry it with cold wind, wrap it on a tray covered with plastic wrap, and refrigerate in a refrigerator at 4°C.

[0016] The Agaricus bisporus preserved by the color-protecting and antistaling agent of the present invention was compared with soaking in clear water, and the results are shown in Table 1.

Abstract

The protective coloration antistaling agent of agaricus bisporus disclosed by the invention comprises 0.01%-0.03% of spermine, 0.1%-0.5% of L-cysteine and the rest of water according to weight percentage. The protective coloration antistaling agent has low price, non-toxicity and convenient use, can effectively control the browning of agaricus bisporus and obviously prolong the commodity price of agaricus bisporus.

Description

technical field [0001] The invention relates to a color-protecting and fresh-keeping agent of Agaricus bisporus. Background technique [0002] After Agaricus bisporus is harvested, the tissues still carry out active metabolic activities. Under normal circumstances, in intact tissues, the phenol-quinone redox system as a respiratory transmitter maintains a dynamic balance. When mushroom tissue cells are damaged, O 2 A large number of invasion, polyphenols in mushroom tissue in O 2 In the presence of conditions, it is oxidized to quinones, and the quinones are further oxidized and polymerized into melanin, which leads to browning. For fresh Agaricus bisporus, browning not only affects the appearance and reduces its nutritional value, but is also a sign of spoilage and unfitness for consumption. At home and abroad, the research on the fresh-keeping technology of Agaricus bisporus is mostly based on low-temperature refrigeration or controlled-atmosphere preservation, which ha...
