Abstract

The invention relates to a processing method of a ginkgo leisure food. The processing method comprises the following specific steps: soaking core-free ginkgo kernels, then autoclaving, and quick-freezing for crystallizing; and then deep-frying in vacuum and at a low temperature, and adding seasonings after deoiling to obtain the ginkgo leisure food, wherein the core-free ginkgo kernels are obtained through three procedures of shelling, hulling and coring of normal ginkgo, and the three procedures are free from sequence limitation. The processing method is simple in operation, short in production period, low in requirements on factories and equipment, and low in energy consumption, maintains complete shapes and no nutrient loss of ginkgo, and also keeps an original flavor of ginkgo.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for processing ginkgo fruit into snack food. Background technique [0002] Ginkgo, also known as ginkgo fruit, Lingyan, duck feet, and bergamot, is the seed of Ginkgo biloba Linn., a plant of the Ginkgoaceae family (Ginkgoaceae) that removes the fleshy outer testa. my country is rich in ginkgo resources, accounting for about 70% of the world's total.
