Embodiment 1

[0160] Embodiment 1 provides a kind of blueberry extract, and the blueberry extract object is prepared by the following method: the blueberry is washed and crushed, with 6 times the volume percent concentration of 80% ethanol aqueous solution (that is, the content of ethanol is 80% (v / v)) Heated and refluxed for 3 times, 3 hours each time, combined the extracts, recovered ethanol under reduced pressure, absorbed the obtained extracts through a macroporous resin, eluted, collected the eluents, concentrated at low temperature, and spray-dried to obtain the blueberry extract. The mass percentage of anthocyanins in the blueberry extract measured by ultraviolet spectrophotometry was 25wt%.

Embodiment 2

[0162] Example 2 investigated the improvement of the mouthfeel of blueberry extracts by maltose, crystalline fructose, glucose, sucralose, ethyl maltol, β-cyclodextrin, ethyl maltol+β-cyclodextrin+crystalline fructose respectively.

[0163] Oral solution preparation

[0164] 2.1 Preparation of blueberry extract oral liquid

[0165] The components of the blueberry extract oral liquid are 0.8 parts by weight of the blueberry extract prepared in Example 1 (containing 0.2 parts by weight of anthocyanins) and 76.8 parts by weight of purified water.

[0166] The preparation method of blueberry extract oral liquid is as follows:

[0167] The blueberry extract and purified water are mixed, stirred evenly to form a mixed solution, filtered, sterilized, and vacuum filled to obtain the blueberry extract oral liquid.

[0168] 2.2 Preparation of maltose + blueberry extract oral liquid

[0169] The components of the maltose+blueberry extract oral liquid are 0.8 parts by weight of the blu...

Embodiment 3

[0192] Example 3 investigates the antioxidant effect of the blueberry extract prepared in Example 1.

[0193] 1 Subject Inclusion Criteria

[0194] Select the age group of 18-65 years old, in good health, without obvious brain, heart, liver, lung, kidney, blood diseases, without long-term medication history, volunteers to ensure cooperation.

[0195] 2 groups of subjects

[0196] 122 subjects were selected and randomly divided into the experimental group and the control group according to the levels of MDA, SOD, and GSH-Px. There were 61 people in the control group and 61 people in the experimental group. Among them, 3 cases left the experimental group (exited because they did not receive the samples on time) , 58 effective cases.

[0197] 3 test method

[0198] Both self- and between-group control designs were used. During the test period, the life and diet of the control group and the experimental group remained unchanged. The experimental group was given the blueberry ...

Abstract

The invention relates to a drug or health-care product or food for resisting oxidation and relieving asthenopia, and particularly provides a composition. The composition comprises a blueberry extractand maltose. According to the drug or the health-care product or the food, through the combined application of the maltose and the blueberry extract, the bitter taste, astringent taste, bitter taste residues, and astringent taste residues of the blueberry extract can be significantly lowered, and the mouthfeel of the blueberry extract is improved; meanwhile, the blueberry extract has excellent effects of resisting oxidation and relieving asthenopia.

Description

technical field [0001] The invention relates to the field of medicine and health care, in particular, the invention relates to a medicine, health product or food for anti-oxidation and alleviating visual fatigue. Background technique [0002] The nutritional value of blueberries is much higher than that of other fruits, and they are often known as "the king of berries in the world". It is also rich in a variety of edible and medicinal elements, and has high value in food, medicine and other aspects. However, poor mouthfeel is one of the inherent defects of oral preparations of blueberry extracts. Currently, blueberry anthocyanin oral liquids on the market all adopt the method of adding a variety of flavoring agents to improve mouthfeel, but flavoring agents are food additives. People's requirements for healthy green food are getting higher and higher, and high-purity health care oral preparations without additives can better meet people's needs. How to improve the mouthfee...
