The invention belongs to the field of
food processing, and particularly discloses a
processing method for sweet-water castanea mollissimas. The
processing method comprises the following steps: a. removing the shells and the unsmooth peels of the castanea mollissimas, then, peeling the yellow peels on the surface of the castanea mollissima
flesh until the surfaces of the castanea mollissimas are smooth; b. adding
sodium hydrosulphite and
ethylenediamine tetraacetic acid disodium to the castanea mollissimas, and washing the castanea mollissimas after boiling the castanea mollissimas in water for three to five hours; the additive
mount of the
sodium hydrosulphite ranges from 0.2 g / kg to 0.4 g / kg and the additive
mount of the
ethylenediamine tetraacetic acid disodium ranges from 0.1 g / kg to 0.25 g / kg; c. boiling the castanea mollissimas in clear water, and washing the castanea mollissimas; d. draining the washed castanea mollissimas, placing the castanea mollissimas into candy liquid to carry out a candy-
boiling process, and cooling the candy-boiled castanea mollissima
flesh until the castanea mollissimas are golden yellow; e. adding the candy liquid into the golden yellow castanea mollissimas,
processing the castanea mollissimas in a
tinning, vacuumizing and germicidal manner, and packaging the castanea mollissimas after the castanea mollissimas are cooled. According to the processing method, the castanea mollissimas which are boiled and washed through additives are boiled in the clear water and washed with the clear water again. Therefore, the
softening property of the sweet-water castanea mollissimas is high and the taste of the sweet-water castanea mollissimas is good, and the residual micro-additives in the castanea mollissimas can be removed maximally to meet
food safety requirements.
