preparation example Construction

[0010] A preparation method of apple whole powder, the steps are as follows:

[0011] 1) Using fresh apples as raw materials, first rinse the apples with clean water, then soak them in a citric acid solution with a concentration of 1% to 1.2% for 5 to 10 minutes, then rinse them with clean water, rinse them and drain them for later use;

[0012] 2) Remove the core and inedible parts of the fruit pedicle, cut the apples into 3-7mm thick apple slices, soak them in the color protection solution for 25-35 minutes, and drain;

[0013] 3) Put the apple slices after color protection in step 2) into a hot air drying oven for pre-drying to a moisture content of 35-45 wt%, then pre-expand the pre-dried apple slices to a moisture content of 15-25 wt%, and then microwave The puffed apple slices are subjected to low-temperature air-flow puffing treatment until the moisture content is below 6wt%, so as to obtain apple crisps;

[0014] 4) Superfinely pulverize, sieve and package the apple c...

specific Embodiment approach

[0030] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

[0031] The apple raw material used in the embodiment is produced in Qixia, Yantai City;

[0032] The electric blast drying oven was purchased from Tianjin Test Instrument Co., Ltd., model: 101-3A;

[0033]The microwave dryer was purchased from Jinan Longtai Microwave Equipment Co., Ltd., model: LT-4S;

[0034] The low-temperature airflow fruit and vegetable puffing dryer was purchased from Tianjin Qinde New Material Technology Co., Ltd., model: QDPH1000-4;

[0035] The ultrafine pulverizer was purchased from Jinan Beili Powder Technology Co., Ltd., model: BFM-6

[0036] The whole apple powder prepared in the embodiment of the present invention is used as a food ingredient in various food fields.

Embodiment 1

[0038] A preparation method of apple whole powder, the steps are as follows:

[0039] 1) Select 10 kg of the remaining extra-grade fruit for canning, first rinse the apples with clear water, then soak them in a citric acid solution with a concentration of 1 wt% for 5 minutes, then rinse them with clear water, rinse them and drain them for later use;

[0040] 2) Remove the core and inedible parts of the fruit pedicle, cut the apples into 5mm thick apple slices, soak in the color protection solution for 30 minutes, and drain; the color protection solution contains ascorbic acid, citric acid, EDTA-2Na, sodium chloride aqueous solution, wherein the mass concentration of ascorbic acid is 0.7%, the mass concentration of citric acid is 0.9%, the mass concentration of EDTA-2Na is 0.1%, and the mass concentration of sodium chloride is 0.5%;

[0041] 3) Put the apple slices after step 2) into a hot air drying oven to pre-dry to a water content of 41.7%. After the apple slices were micr...

Abstract

The invention relates to a preparation method of whole apple powder. According to the preparation method, off-grade fruits and low-specification fruits from apples which can be freshly eaten or can be made into cans and apple crispy chips, and leftover materials obtained in a process of preparing apple rings and the apple crispy chips are used as raw materials and apples are subjected to slicing and color protection; then the apple slices are put into a hot air drying box to be pre-dried until the water content is 35wt%-45wt%; then the pre-dried apple slices are subjected to microwave pre-puffing until the water content is 15wt%-25wt%; and the apple slices subjected to the microwave pre-puffing are subjected to low-temperature airflow puffing treatment until the water content is less than 6wt% to obtain the apple crispy chips; and finally, superfine grinding, sieving and packaging are carried out to obtain the whole apple powder. The prepared whole apple powder has good instant property, retention ability and dissolving stability; sediment is not easy to form in a dissolving process and the whole apple powder is not caked and clustered after being dissolved into water; the retention ability of the apple powder is strong; and apple resources are comprehensively and efficiently utilized.

Description

technical field [0001] The invention relates to a preparation method of whole apple powder, which belongs to the technical field of food processing. Background technique [0002] Apple is not only the largest fruit in my country, but also a good product among fruits. It is rich in nutrition, contains a variety of vitamins and amino acids, and contains a variety of mineral elements necessary for the human body, such as: potassium, sodium, calcium, magnesium, iron, zinc , manganese, copper, selenium, etc. In 2012, my country's apple production reached 38.49 million tons. At present, apples are mainly eaten fresh, and processed products mainly follow the traditional processing methods, mainly concentrated fruit juice processing, and a small amount of canned and preserved fruit processing. Processing apples into apple powder can extend the storage period, reduce storage and transportation costs, and reduce the huge economic losses caused by the low-value utilization of raw mate...
