Embodiment 1

[0021] (1) Cold-pressed degreasing of raw materials: avocado kernels are crushed in a 2000r / min high-speed crusher for 28 seconds, and the crushed macadamia nuts are dried by infrared to 4% moisture content, infrared wavelength 6μm, heat source temperature 500℃, heat source and nuts The distance is 8cm; the macadamia nuts irradiated by infrared rays are wrapped with filter cloth and put into the cylinder of hydraulic oil press, adjust the pressure to 60MPa, press 3 times at 45℃, and collect the avocado pulp; (2) Conditioning: Weigh 1kg avocado pulp, add 8kg purified water, stir evenly, adjust the pH value to 9.0 with 1mol / L NaOH solution; (3) Refining and homogenizing the pulp: the refined mixture is refined by colloid, The gap between the stator and the rotor of the colloid mill is 30 microns, and then the homogenizer is used to homogenize and refine, and the homogenization pressure is 45MPa; (4) Dynamic ultra-high pressure treatment: The fruit pulp is processed by M-110EH type...

Embodiment 2

[0023] (1) Cold-pressed degreasing of raw materials: avocado nuts are crushed in a high-speed pulverizer of 1800r / min for 30s, and the crushed macadamia nuts are dried with infrared rays to 3% moisture content, infrared wavelength 5μm, heat source temperature 400℃, heat source and nuts A distance of 10cm; the macadamia nuts irradiated by infrared rays are wrapped in filter cloth and put into the cylinder of the hydraulic oil press, adjusted to 55MPa, pressed 3 times at 50°C, and collected avocado pulp; (2) Modification of the pulp: Weigh 1kg of avocado pulp, add 7kg of purified water, stir evenly, adjust the pH value to 9.0 with 1mol / L NaOH solution; (3) Refining and homogenizing the pulp: the refined mixture is refined by colloid, The gap between the stator and rotor of the colloid mill is 25 microns, and then the homogenizer is used to homogenize and refine, and the homogenization pressure is 50 MPa; (4) Dynamic ultra-high pressure treatment: The fruit pulp is processed 3 time...

Abstract

The invention relates to a separation method of avocado nutlet protein. The separation method mainly comprises the following steps: (1) cutting up avocado nutlets, and performing infrared processing and hydraulic cold pressing to separate out avocado nut oil; (2) mixing the obtained fruit dregs with purified water, conditioning with alkaline, adopting a colloid mill and a homogenizer to process, and then performing dynamic ultrahigh-pressure processing; (3) regulating the pH value of the fruit dregs till isoelectric point, separating out the dregs, and spray drying at a low temperature to obtain the avocado protein. The technical links are continuous and compact; the product is high in yield and good in quality.

Description

Technical field [0001] The invention relates to a method for extracting fruit protein, in particular to a method for separating avocado kernel protein. Background technique [0002] Avocado, also known as avocado, avocado or avocado, has high nutritional value and is rich in fat, protein, minerals and various vitamins necessary for the human body. It enjoys the reputation of "the source of life". It is also known for its high fat content. As "Forest Butter". [0003] Avocado research at home and abroad mainly focuses on the cultivation and preservation of avocado and the extraction and utilization of avocado oil. At present, there are very few studies on the extraction of avocado protein. Avocado protein is generally encapsulated in cells and binds tightly with other components such as fruit oil and fiber. It is difficult to separate. The general extraction methods are not efficient and may damage the protein. Summary of the invention [0004] In order to overcome the problems of...
