Embodiment approach

[0016] In the present invention, a preferred embodiment of the method for extracting cranberry extract comprises the following steps:

[0017] (1) Alcohol extraction: under acidic conditions, use ethanol aqueous solution to extract the cranberry raw material, and coarsely filter to obtain the extract;

[0018] (2) Ethyl acetate extraction: the extract is suction filtered to obtain the filtrate, then the filtrate is concentrated under reduced pressure until the relative density is 1-1.5 to obtain the liquid to be extracted, and then extracted with ethyl acetate;

[0019] (3) Drying: the extract is vacuum-dried until the moisture content is less than 5% by weight;

[0020] (4) Pulverization and sieving: pulverize the dry matter and pass through a 60-100 mesh sieve.

[0021] In the step (1) of the bilberry extract extraction method of the present invention, the solid-to-liquid ratio (weight ratio) of the bilberry raw material to the ethanol aqueous solution is 1: 8-15; the extra...

Embodiment 1

[0052] This example is used to illustrate the cranberry extract provided by the present invention and its preparation method.

[0053] (1) Alcohol extraction: extract the bilberry with a 75% ethanol aqueous solution with a mass concentration of 75%, the ratio of solid to liquid (weight ratio) is 1:10, adjust the pH to 3.0 with HCl, extract at 60°C for 1 hour, and coarsely filter to obtain the extract ;

[0054] (2) Ethyl acetate extraction: filter the extract through a plate-and-frame filter to obtain the filtrate, and then concentrate the filtrate under reduced pressure at a vacuum degree of -0.06MPa and a temperature of 65°C until the relative density is 1.2 (60°C). Obtain the liquid to be extracted, then extract with 2 times the volume of ethyl acetate, and extract twice;

[0055] (3) Drying: vacuum-dry the extract at a vacuum degree of -0.08MPa, below 60°C, until the moisture content is less than 5% by weight;

[0056] (4) Pulverization, sieving, and inspection: the dry ...

Embodiment 2

[0058] This example is used to illustrate the oral preparation provided by the present invention and its preparation method.

[0059] (1) premixing: take by weighing 100g lutein raw material, 70g of the cranberry extract that embodiment 1 makes pass respectively 40 mesh sieves, mix;

[0060] (2) Mixing and granulation: take by weighing 271g microcrystalline cellulose, mix uniformly with the above-mentioned premix, add ethanol that accounts for 15% by weight of the mixture and have a mass concentration of 50%, and stir to obtain wet granules; then wet granules The material is transferred to the boiling drier for drying. When the temperature reaches 45°C, keep it warm for 25 minutes and then cool it down to below 40°C. When the water content of the pellets is 4% by weight, discharge the pellets and pass through a 20-mesh sieve to obtain dry pellets;

[0061] (3) 4.5g of magnesium stearate was weighed, mixed uniformly with dry granules, compressed into tablets and packaged to ob...

Abstract

The invention relates to the field of functional foods, and discloses a food composition and oral preparation for improving visual fatigue, and a preparation method of the oral preparation. The food composition for improving visual fatigue is prepared from the active components in parts by weight: 100 parts of a lutein raw material and 30-150 parts of a bilberry extract relatively. The invention further discloses the oral preparation for improving visual fatigue and the preparation method thereof. The active components of the bilberry extract and lutein are combined to complement each other and achieve the effects of protecting eyes, relieving visual fatigue and preventing shortsightedness jointly, and the food composition is suitable for improving visual fatigue symptoms such as ophthalmalgia, eye swelling, photophoby, vision blurring and eye dryness, can be eaten for a long term, and is safe and free of side effects.

Description

technical field [0001] The invention relates to the field of functional food, in particular to a food composition for improving visual fatigue, an oral preparation and a preparation method thereof. Background technique [0002] Visual fatigue is a group of syndromes caused by single or interactive factors such as poor visual work environment, visual organ dysfunction, systemic organic disease and psychological abnormalities. The following symptoms often appear in stages when the eyes are overused and the physical and mental state is not good: reading and writing cannot be sustained, blurred vision or double image visual impairment; eye swelling, eye pain, dry eyes, tearing, itching and foreign body sensation eye discomfort ; chronic conjunctivitis, stye, chalazion and ocular surface lesions of blepharitis; headache, insomnia, memory loss and other systemic symptoms. In recent years, with the change of information exchange methods and the accelerated pace of work, the number...
