Embodiment 1

[0048] (1) Select highland barley grains with a β-glucan content of 4 to 8 wt%, wash, remove impurities, dry, grind and sieve to obtain highland barley bran that has not passed 60 mesh; after ultrafine grinding the highland barley bran, separate to obtain 100-300 μm aleurone layer of debraned highland barley.

[0049] (2) 20 parts by weight of the bran-free highland barley aleurone layer, 70 parts by weight of refined highland barley powder, 10 parts by weight of potato flour, and 5 parts by weight of oat flour are sent into the mixer for uniform mixing, and the material is continuously discharged from the lower outlet of the mixer, and then Pour into the upper inlet to keep the original powder uniform - so as to form a compound powder;

[0050] (3) Send the compound powder into the hopper of the twin-screw extruder, adopt the automatic mode, and set: the feed rate is 10kg / h, the water addition is 20%, T1 is 50°C, T2 is 65 ℃, T3 is 105°C, T4 is 115°C, T5 is 75°C and T6 is 45°...

Embodiment 2

[0053] (1) Select highland barley grains with a β-glucan content of 4 to 8 wt%, wash, remove impurities, dry, grind and sieve to obtain highland barley bran that has not passed 60 mesh; after ultrafine grinding the highland barley bran, separate to obtain 130-300 μm aleurone layer of debraned highland barley.

[0054] (2) 25 parts by weight of the bran-free highland barley aleurone layer, 70 parts by weight of refined highland barley flour, 10 parts by weight of potato flour, and 10 parts by weight of oat flour are sent into the mixer for uniform mixing, and the material is continuously discharged from the lower outlet of the mixer, Then pour it into the upper inlet to keep the original powder evenly - so as to form a compound powder;

[0055] (3) Send the compound powder into the hopper of the twin-screw extruder, adopt the automatic mode, and set: the feed rate is 15kg / h, the moisture addition is 21%, and the six temperature zones are set to T1 to 55 ℃, T2 is 70°C, T3 is 10...

Abstract

The invention discloses a de-wheat bran barley aleurome layer compounded extruded rice and a preparation method thereof. The de-wheat bran barley aleurome layer compounded extruded rice comprises thefollowing components: 20-40 parts by weight of a de-wheat bran barley aleurome layer, 50-75 parts by weight of refined barley flour, 10-30 parts by weight of potato powder, and 5-25 parts by weight ofoatmeal. The de-wheat bran barley aleurome layer is added to the existing coarse grain raw materials, the processing method is correspondingly adjusted, so that the processed extruded rice has a higher content of beta-glucan and a content of the barley aleurone layer, and is helpful for increasing the nutritional value of the extruded rice.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and more specifically relates to extruded rice compounded with bran-free highland barley aleurone layer and a preparation method thereof. Background technique [0002] Highland barley bran is rich in physiologically active components with health care and medicinal value, a reasonable nutritional structure that can promote human health and longevity, and has extremely high nutritional and therapeutic value; highland barley bran contains a large amount of β-glucan, which has a relatively high High health value and nutritional value; highland barley bran is also rich in a variety of amino acids, protein, dietary fiber, VB 2 The content is also higher, and it also contains trace elements such as zinc, calcium, iron, selenium, etc. necessary for human life. Most of these beneficial components are gathered in the aleurone layer of highland barley bran, and the aleurone layer is closely adhere...
