Embodiment 1

[0032] This embodiment provides a kind of preparation method of hawthorn chips, described method is carried out according to the following steps:

[0033] S01: Pretreatment of raw materials: Wash and remove the pitted fresh hawthorns that are fully mature, free from mildew, dry scars and injuries, and cut into 5 mm thin slices.

[0034] S011: Microwave treatment: microwave the hawthorn slices cut in step S01 for 80 s at a microwave power of 600 W;

[0035] S02: Ultrasonic hot water blanching: blanching the hawthorn slices after the microwave treatment in the step S011 for 55 s under the condition of ultrasonic power of 540 W and water temperature of 90°C;

[0036] S03: Vacuum pre-drying and wet equalization: quickly vacuum-dry the hawthorn slices blanched with ultrasonic hot water in the step S02. The content is 30%; then put the dried hawthorn slices into a sealed bag, and keep them wet for 24 hours at a temperature lower than 10°C.

[0037] S04: High-pressure air-flow puff...

Embodiment 2

[0041] This embodiment provides a kind of preparation method of hawthorn chips, described method is carried out according to the following steps:

[0042] S01: Pretreatment of raw materials: Wash and remove the pitted fresh hawthorns that are fully mature, free from mildew, dry scars and injuries, and cut into thin slices of 4 mm.

[0043] S011: Microwave treatment: microwave the hawthorn slices cut in step S01 for 60 s at a microwave power of 800 W;

Abstract

The invention provides a making method of haw crisp chips. The making method comprises the steps of pretreating raw materials, performing microwave treatment, performing ultrasonic blanching with hotwater, performing vacuum pre-drying and uniform wetting, performing high-pressure draft puffing, performing low-temperature vacuum drying and the like. Through microwave treatment and ultrasonic blanching treatment with hot water, the tissue structure of haw chips is changed, so that the haw chips are compact no longer, puffing is smoothly performed through the high-pressure draft puffing step, and the haw crisp chips are obtained; and in the entire process, the operation temperature is low, the haw chips cannot generate brown stains, the intrinsic color, the intrinsic texture and the intrinsic nutrient components of the haws are reserved to the maximum extent, and the haw crisp chips are crisp in mouth feel, excellent in quality and low in making cost.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of hawthorn chips. Background technique [0002] Hawthorn belongs to the Rosaceae plant, and the planting area of ​​hawthorn is large in China. It is a unique tree species with both medicinal and fruit functions in China. Its fruit has high nutritional and medicinal value. Hawthorn, as an important medicinal and edible food, is more and more popular among consumers, and its processing has also begun to develop in multiple ways. At present, the processed products related to hawthorn on the market mainly include hawthorn liqueur, hawthorn jelly, hawthorn slices, fruit skin and canned hawthorn, etc., but these products are too high in sugar to meet people's needs. Therefore, efficient, high-quality, nutritious and environmentally friendly hawthorn Deep processing research has become a new hot spot. [0003] In recent years, people pay more and more att...
