Problems solved by technology

Due to the high content of oil in hazelnut kernels, unsaturated fatty acids in the oil account for more than 90%, unsaturated fatty acids are easy to oxidize and deteriorate, so hazelnut kernels are difficult to store, and the shelf life is short, which affects hazelnut kernels as raw materials or further processing applications of ingredients
In the prior art, there is no better method for processing hazelnut kernels into raw materials or ingredients that are easy to store and have a long shelf life

Embodiment 1

[0013] The preparation method of hazelnut powder has the following steps:

[0014] 1. Take the hazelnuts, shell the hazelnuts, and get the hazelnut kernels;

[0015] 2. Press the hazelnut kernels with a low-temperature cold-pressed oil press to obtain pressed hazelnut oil and pressed cakes;

[0016] 3. Pulverize the pressed meal cake so that the particle size of the pressed meal cake after crushing is 45 meshes to obtain pressed meal cake powder;

[0017] 4. Extract pressed meal cake powder with carbon dioxide supercritical extraction method, separate and extract hazelnut oil to obtain hazelnut powder, and extract pressed meal cake powder with carbon dioxide supercritical extraction method to separate and extract hazelnut oil to obtain hazelnut powder. The pressure is: 25MPa, the extraction temperature is: 55°C, the extraction time is: 2.5h, the carbon dioxide flow rate during extraction is: 120L / h, when separating, the primary separation pressure is 6MPa, the primary separat...

Embodiment 2

[0019] In the process of extracting pressed cake powder with carbon dioxide supercritical extraction method, separating and extracting hazelnut oil to obtain hazelnut powder, the extraction pressure is: 24MPa, the extraction temperature is: 60°C, the extraction time is: 2h, and the flow rate of carbon dioxide during extraction is: : 130L / h, other steps with embodiment 1.

Embodiment 3

[0021] In the process of extracting pressed cake powder with carbon dioxide supercritical extraction method, separating and extracting hazelnut oil to obtain hazelnut powder, the extraction pressure is: 26MPa, the extraction temperature is: 50°C, the extraction time is: 3h, and the flow rate of carbon dioxide during extraction is: : 110L / h, other steps with embodiment 1.

Abstract

The present invention relates to a preparation method of filbert powder, which comprises the steps of pressing the husked filbert nut at low temperature by oil press so as to separate the filbert oil and obtain cake, crushing the cake to powder with the particle diameter of 40-60 mesh, extracting the powder by supercritical CO2 extraction(CO2-SFE) so as to separate extracted filbert oil and obtain filbert powder, wherein the extracting process has the conditions of 24-26 MPa of pressure, 50-60 DEG C of temperature, 2-3 hours of extracting time, and 110-130 L / h of CO2 flux. In the present invention, partial filbert oil in filbert nut is separated by cold pressing at low temperature firstly, and then filbert oil in the cake obtained after cold pressing is separated by CO2-SFE, thereby, the grease content in the filbert powder can be less than 2%, so that the filbert powder contains the major nutrient contents of filbert nut except grease. Furthermore, the filbert powder holds the special aroma of filbert nut, can be used as raw material or ingredients to produce foods with many kinds of flavors, and is easy to storage with a long shelf life.

Description

technical field [0001] The invention relates to a processing method for hazelnuts, in particular to a method for preparing hazelnut powder from hazelnuts. Background technique [0002] Hazelnut is a kind of wild nut. Hazelnut kernel contains a variety of ingredients that are very beneficial to human health. The content of oil in hazelnut kernel is relatively high, and unsaturated fatty acids in oil account for more than 95%. Hazelnut kernel In addition to oil, there are special ingredients such as protein, carbohydrates, vitamins, minerals, fiber, beta-sterol and antioxidant carbolic acid. It is a nut food that is very beneficial to human health. Hazelnut kernels have a special aroma , Pleasant taste, besides direct consumption, hazelnut kernels can also be eaten in a variety of ways, and hazelnut kernels can also be used as raw materials or ingredients to process a variety of foods with unique flavors. Due to the high oil content in hazelnut kernels, unsaturated fatty acid...
