Description
Technical Field
The invention belongs to the technical field of refrigerators, and particularly relates to a refrigerator with a fruit and vegetable freezing storage function and a control method.
Background
The season-oriented fruits and vegetables have high nutritive value and good flavor, but the shelf life is short, and the season-oriented vegetables cultured in the greenhouse have obviously reduced flavor and nutritive value and higher price due to the influence of the growth environment. Users often place season vegetables in the freezer compartment of the refrigerator for storage.
The food materials which can be stored in the freezing chamber comprise beans such as green beans, corn kernels, durian and lychee and tropical fruits with high respiratory intensity. The storage method commonly used by users is bag storage. However, the conventional freezing method can cause damage to the sensory substances and flavor substances of the food materials. Ice crystals, as produced by conventional freezing (slow freezing), can disrupt the cellular structure of the food material, leading to loss of nutrients during thawing.
Earlier researches show that the fruits and vegetables can be rapidly cooled under the conditions of-32 to-40 ℃ and 94 to 97kPa, the freezing speed of the food materials is improved by tens of times compared with that under the condition of-18 ℃, and meanwhile, the fruits and vegetables can be promoted to rapidly lose extracellular water by pressure reduction treatment, so that the damage to the quality of the food materials caused by the formation of ice crystals is reduced. Meanwhile, the protection of the color of the food material can be realized by combining the light-shielding treatment.
