Embodiment 1

[0032] A processing method of macadamia nuts, comprising the following steps:

[0033] a. Grain selection: macadamia nuts with a particle size between 16-24mm, complete shape and full particles are selected for use;

[0034] b. Hole opening: four holes are opened at an equal distance along the macadamia nut equator, one hole is opened at the north and south poles, the depth of the hole does not touch the nut, and compressed air is passed into the hole;

[0035] c. Packing: Put the pre-opened macadamia nuts into the cavity of the fruit plate one by one, and close the cover;

[0036] d. Soaking liquid: put the fruit tray into the closed ultrasonic sheller, immerse in the material liquid, and soak for 1 hour after starting the machine;

[0037] e. Separation: place the soaked fruit plate in the separation tank, separate the nuts from the endocarp and shell through the action of water flow, and then stand in a cool and ventilated place for 3 hours;

[0038] f. Drying: Put the ma...

Abstract

The present invention provides a processing method of macadamia fruits and belongs to the technical field of food. The processing method of the macadamia fruits comprises the following steps: a, fruitselecting is conducted: macadamia fruits are sieved to select the macadamia fruits with a particle size of 16-24 mm; b, hole opening is conducted: four holes are opened equally along equator lines ofthe macadamia fruits; each hole is opened in north and south poles; the hole opening depth does not reach fruit kernels; and compressed air is introduced into the holes; c, plate loading is conducted: the macadamia fruits after the hole opening are placed on a fruit plate holder one by one; and a bottom cover covers the fruit plate holder; d, soaking is conducted: the fruit plate holder is put into a closed ultrasonic shelling machine and soaked with material liquid for 1-3 h; e, separating is conducted: the soaked fruit plate holder is placed in a separation groove, so that the fruit kernelsare separated from inner fruit peels and outer shells; and f, drying is conducted: the macadamia fruit kernels are placed in an oven to be dried at 40-100 DEG C for 6-10 h. The provided processing method of the macadamia fruits is simple and easy to operate in shelling, and suitable for large-scale development, can ensure the integrity of the fruit kernels, and is conducive to a long-term storage.

Description

【Technical field】 [0001] The invention relates to the technical field of food, in particular to a processing method of macadamia nuts. 【Background technique】 [0002] Macadamia nuts are a tree nut native to Australia, also known as macadamia nuts, Queensland chestnuts, etc. Macadamia nuts are rich in nutrition, with a single fruit weighing 15-16 grams, oil content of 70-79%, protein 9%, containing 8 kinds of amino acids necessary for the human body, and also rich in vitamins and minerals. Macadamia nuts are crispy, smooth, tender and delicious, with a unique buttery aroma. They are edible nuts with the highest quality in the world. They are known as the "Queen of Thousand Fruits" and "King of Nuts in the World". [0003] The exocarp of macadamia nuts is green and the inner peel is hard. It is necessary to use a shell-opening tool to break the shell and take out the nuts. In the prior art, the fracturing method is usually used, that is, to squeeze cracks or cut incisions on ...
