Problems solved by technology

However, most of the walnut oil currently available in the market is bottled, which is not only inconvenient for transportation, but also unfavorable for storage. Once opened, the walnut oil is prone to oil oxidation, which reduces the nutritional value. In severe cases, it will also cause rancidity and produce an unpleasant smell , reduce shelf life

Embodiment 1

[0010] The object of the present invention is to provide a kind of preparation method of porous starch-embedded walnut oil powder that is convenient for processing, beneficial to storage, and easily digested and absorbed by the human body, comprising the following steps:

[0011] Preparation of walnut oil powder: take a certain amount of walnut oil in a beaker, add a certain amount of porous starch to make the mass volume concentration (W / V) of the porous starch reach 20-45%, fully stir, mix evenly, and carry out with a spray drier. Spray drying, spray drying conditions: inlet air temperature 160°C-185°C; outlet air temperature 80°C-88°C; flow rate 8.5ml / min; atomizer speed 25000-45000r / min. The powdered walnut oil is prepared and packaged and sealed.

Embodiment 2

[0013] Using walnut oil as the material, accurately measure 100mL of walnut oil into a beaker, add 20 grams of porous starch to make the mass volume concentration of the starch reach 20%, stir well to mix the starch and walnut oil evenly, the air inlet temperature is 175°C, and the air outlet The temperature is 84° C., the flow rate is 8.5 ml / min, and the atomizer rotates at 30,000 r / min to carry out spray drying to prepare powdered walnut oil, which is packaged and sealed. After being stored at room temperature for 18 months, compared with the walnut oil without embedding agent, the deterioration rate is reduced by 36%, and the shelf life of the porous starch-embedded walnut oil powder can reach 32 months.

Embodiment 3

[0015] Using walnut oil as the material, accurately measure 100mL of walnut oil into a beaker, add 32 grams of porous starch to make the mass volume concentration of the starch reach 32%, stir well to mix the starch and walnut oil evenly, the air inlet temperature is 175°C, and the air outlet The temperature is 84° C., the flow rate is 8.5 ml / min, and the atomizer rotates at 30,000 r / min to carry out spray drying to prepare powdered walnut oil, which is packaged and sealed. After storage at room temperature for 18 months, compared with the walnut oil without embedding agent, the deterioration rate is reduced by 29%, and the shelf life of the porous starch-embedded walnut oil powder can reach 28 months.

Abstract

The invention discloses a method for preparing porous starch embedded walnut oil powder, comprising the following steps: weighing a certain amount of walnut oil, adding a certain amount of porous starch to allow the mass-volume concentration to reach 20-45 %, fully stirring, uniformly mixing, carrying out spray drying by a spray dryer to prepare powdery walnut oil, packaging, and sealing, wherein the conditions of spray drying comprise an air inlet temperature of 160-185 DEG C, an air out temperature of 80-88 DEG C, a flow of 8.5 ml / min, and a rotating speed of an atomizer being 25000-45000 r / min. Compared with walnut oil without using an embedding agent, the deterioration rate is reduced by up to 36 %, and the shelf life of the porous starch embedded walnut oil powder can be as long as 32 months.

Description

technical field [0001] The invention relates to a preparation method of porous starch-embedded walnut oil powder, which belongs to the technical field of food processing. Background technique [0002] Walnuts are known as "Longevity Son" and "Longevity Fruit". "Compendium of Materia Medica" identifies that it can nourish qi and blood, moisten dryness and resolve phlegm. It is called "Hercules Food" and "Puzzle Fruit" abroad. The nutritional value of walnuts has been recognized and admired by people since ancient times. In walnuts, natural vitamins A, B1, B2, E, C, carotene, and trace elements such as sodium, iron, zinc, selenium, and niacin are extremely rich. And it is rich in unsaturated fatty acids necessary for the human body - linoleic acid and a-linolenic acid (brain gold DHA parent). Its unique natural nutritional ingredients are especially suitable for pregnant women, infants, students, mental workers and sub-healthy people. Walnuts not only have high nutritional...
