Abstract

The invention discloses ready-to-eat cucurbita pepo slices and a preparation method thereof. The ready-to-eat cucurbita pepo slices are obtained by sorting materials, slicing, blanching, putting into a dish, prefreezing, lyophilizing, carrying out desorption drying, and carrying out vacuum packaging, wherein the safety moisture content of the obtained cucurbita pepo slices is 1%-5%. According to the invention, the cucurbita pepo slices are blanched and cooked by boiled water, and are dried by combining a vacuum freeze drying technique, so that the toxicity of the raw cucurbita pepo slices can be eliminated, the quality of the dried cucurbita pepo slices can be improved, and the cucurbita pepo slices are bright in color, are unlikely to coke, and have thick flavor of the cucurbita pepo; an approach is developed for drying the cooked cucurbita pepo slices by blanching of boiled water and the vacuum freeze-drying technique, and the preparation is easy to control timely, and the true continuous automatic clean production can be realized.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to instant zucchini slices and a preparation method thereof. Background technique [0002] Zucchini is a popular vegetable, rich in vitamin C and calcium, so it has high medicinal and edible value, and is a recognized health food. Although the nutritional value of zucchini is high, it is easy to age, rot and deteriorate when stored at room temperature, and it is easy to be poisoned if eaten raw. Therefore, scalding and drying zucchini slices is one of the important ways of zucchini processing. At present, dried zucchini products are mainly dried with hot air, which takes a long time to dry, resulting in low product yield, dark color, high nutritional loss, poor flavor and needs to be reprocessed when eating. The invention provides a method for making edible zucchini slices. The obtained dried zucchini slices are not only crisp but not fragile, but can also retain the col...
