Problems solved by technology

[0004] However, because chestnut itself is afraid of heat, is perishable, and is easy to be eaten by insects, it is difficult to preserve at room temperature, so its reprocessed products must first solve the problem of fruit quality preservation, but currently available in the market. There is a problem of dark browning of the product, which affects the senses and appetite of the eaters. In addition, due to the change of the processing season and the extension of the shelf life of the product, the strong original taste of the chestnut is weakened.

Abstract

The invention discloses a processing method of instant Chinese-chestnut. The method comprises steps of pretreating raw materials, dipping with plant preserving liquid, rinsing, freezing rapidly, cooking, packaging and sterilizing by intense pulsed light. According to the processing method, the extract of natural plant raw materials is used to dip the Chinese chestnut kernel. By the natural sterilizing, disinfecting microbe-inhibiting effective components of the traditional Chinese medicines, preservation of the Chinese chestnut kernel is achieved, and the fragrance and tissue state of the Chinese chestnut kernel are preserved. The instant Chinese chestnut has a characteristic of long preservation time. The natural light fragrance of the Chinese chestnut is enhanced and the instant Chinese chestnut has a unique flavor. Chinese wolfberry, propolis, and other natural plant components increase the nutrition healthcare value. The processing process of the product is free of other antiseptics or chemical additives. The instant Chinese chestnut is a green and convenient leisure food.
