Problems solved by technology

[0004] At present, walnut processing at home and abroad is mainly based on dry walnut kernels and there is no report about adding walnut green peel into walnut food processing. Nutrients are lost during the process, and the walnut green peel tastes bitter and astringent. It is rarely used in the field of food processing, and it is difficult to add it to the entire production line of walnut food processing, resulting in waste of walnut green peel. It has extensive practicability and development value.

Embodiment 1

[0029] Embodiment one: green walnut microcapsule powder

[0030] The invention specifically provides a green walnut microcapsule powder, which is prepared by taking young walnut pulp and walnut green peel powder as core materials, and using chitosan, β-cyclodextrin and gelatin as wall materials; It includes 20-60 parts of tender walnut pulp, 1-5 parts of walnut green skin powder, 1-10 parts of chitosan, 5-25 parts of β-cyclodextrin, and 1-10 parts of gelatin.

[0031] Preferably, the present invention provides a green walnut microcapsule powder, which is prepared from tender walnut pulp and walnut green peel powder as core materials, and chitosan, β-cyclodextrin and gelatin as wall materials; In terms of parts by weight, it includes 35-55 parts of tender walnut pulp, 3-5 parts of walnut green skin powder, 5-7 parts of chitosan, 10-20 parts of β-cyclodextrin, and 2 parts- 5 servings.

[0032] More preferably, the present invention provides a green walnut microcapsule powder, ...

Embodiment 2

[0033] Embodiment two: the preparation method of green walnut microcapsule powder

[0034] On July 10th, fresh walnuts were picked before they were fully ripe. During the half pulp and half water state of the walnuts before they were fully ripe, the green skins were removed and impurities were removed; the obtained walnut green skins were quickly frozen at -75°C into hard frozen green skins. After that, it is crushed at a high speed into walnut green skin powder; the fresh walnuts that have been peeled off are broken into shells, the shells and walnut kernels are separated, and the tender walnut kernels are beaten at a speed of 5000r / min to become walnut pulp; the walnut pulp, walnut green peel powder, and shell Add all the sugar into deionized water, stir and mix, then add β-cyclodextrin and gelatin, continue to stir and mix evenly, transfer to an atomizing dryer and spray dry at a temperature of 120°C to obtain green walnut microcapsule powder.

Embodiment 3

[0035] Embodiment three: the preparation method of green walnut microcapsule powder

[0036] Pick fresh walnuts before they are fully ripe on July 20. During the half pulp and half water state of the walnuts before they are fully ripe, the green skins are removed and impurities are removed; the obtained walnut green skins are quickly frozen at -55°C into hard frozen green skins. Grinding at high speed into walnut green skin powder; breaking the fresh walnut shells off, separating the shells and walnut kernels, taking tender walnut kernels and beating at a speed of 6000r / min to form walnut pulp; mixing walnut pulp, walnut green peel powder, chitosan All were added into deionized water, stirred and mixed, then β-cyclodextrin and gelatin were added, continuously stirred and mixed evenly, transferred to an atomizing dryer and spray-dried at a temperature of 130° C. to obtain green walnut microcapsule powder.

Abstract

The present invention discloses green husk walnut microcapsule powder and a preparation method thereof. The green husk walnut microcapsule powder is prepared from a tender walnut kernel slurry and walnut green husk powder as core materials, and chitosan, beta-cyclodextrin and gelatin as wall materials. The green husk walnut microcapsule powder comprises the following raw materials in parts by weight: 20-60 parts of the tender walnut kernel slurry, 1-5 parts of the walnut green husk powder, 1-10 parts of the chitosan, 5-25 parts of the beta-cyclodextrin and 1-10 parts of the gelatin. By using a series of key technical means of non-ripen green husk walnut picking, walnut green husk freezing and crushing, tender walnut kernel slurry beating, mixing and homogenizing, spray drying, etc., a water-soluble protein content of the obtained green husk walnut microcapsule powder is up to 623 mg / 100 g and a vitamin C content reaches 104 mg / 100 g, which are much higher than those of existing products. Besides, a love ratio in a fuzzy matrix evaluation reaches 97%, and the green husk walnut microcapsule powder is suitable for food industry production and has a good development value.

Description

technical field [0001] The present invention mainly relates to the technical field of food processing, in particular, the present invention relates to the technical field of walnut processing. Background technique [0002] Walnut, also known as walnut, Qiang peach, is a Juglandaceae plant, and is known as the world-renowned "four major dried fruits" together with almonds, cashew nuts, and hazelnuts. Ripe walnuts are rich in nutrients, including protein, fat, carbohydrates, calcium, phosphorus, iron and other trace elements and minerals, of which fat is the main one. Because of its high nutritional value, reports on walnut production and processing methods emerge in endlessly, but these processing methods are mostly based on mature walnut kernels as raw materials. Recent studies have shown that walnuts are in the half pulp and half water state before they are fully ripe, that is, For walnuts picked from July to early August, the amino acid content and soluble protein content...
