Embodiment 1

[0046] Such as figure 1 Shown, the extraction method of a kind of blueberry anthocyanin of the present embodiment comprises the steps:

[0047] (1) material selection

[0048] Select blueberries with a complete surface and no signs of decay, place them in a cleaning tank added with physiological saline, and carry out decontamination treatment on the surface of blueberries. The surface decontamination treatment lasts for 3 minutes each time;

[0049] (2) Preparation of Aspergillus oryzae fermented rice product

[0050] Take 50 parts of high-quality rice, wash it with water, add water to soak until the rice has no hard core, then put the soaked rice into the rice cooker and cook until the rice is cooked and not sticky, then divide the cooked rice into The container is inoculated with Aspergillus oryzae according to the inoculation amount of 2%, mixed evenly, and then fermented at 32°C and 90% humidity for 3 days;

[0051] Get the rice fermented for 3 days and put it into a co...

Embodiment 2

[0068] Such as figure 1 Shown, the extraction method of a kind of blueberry anthocyanin of the present embodiment comprises the steps:

[0069] (1) material selection

[0070] Select blueberries with a complete surface and no signs of decay, place them in a cleaning tank added with physiological saline, and carry out decontamination treatment on the surface of the blueberries. The surface decontamination treatment is performed 3 times, each lasting 6 minutes;

[0071] (2) Preparation of Aspergillus oryzae fermented rice product

[0072] Take 58 parts of high-quality rice, wash it with water, add water to soak until the rice has no hard core, then put the soaked rice into the rice cooker and cook until the rice is cooked and not sticky, then divide the cooked rice into The container is inoculated with Aspergillus oryzae according to the inoculation amount of 4%, mixed evenly, and then fermented at 36°C and 95% humidity for 3.5 days;

Abstract

The invention relates to the technical field of extraction of natural products, and provides an extracting method of blueberry anthocyanins. The extracting method comprises the following steps: (1) material selection; (2) preparation of an aspergillus oryzae fermented rice product; (3) pretreatment of raw materials; (4) enzymolysis and wall breaking; (5) extraction of the blueberry anthocyanins; (6) impurity removing; (7) concentration and ultrafiltration; (8) column chromatography purification; (9) drying. The extracting method provided by the invention not only is convenient to operate and beneficial for industrialization, but also enables blueberry cells to release more anthocyanins, so that the extracting efficiency of the blueberry anthocyanins is greatly increased, the technologicalcost is reduced, the economic benefit is increased, and the technological operation difficult is also reduced; a technique and a technology used by the method have larger operability and applicability.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, in particular to a method for extracting blueberry anthocyanins. Background technique [0002] Blueberry, scientific name Vaccinium, belongs to the genus Vaccinium of Rhododendronaceae. Blueberry fruit is a berry, nearly round and blue in color. It is one of the rare blue foods. Studies have shown that blueberry anthocyanin is a powerful antioxidant that protects the human body from free radical damage, enhances immunity, and has good curative effects on ophthalmic diseases and cardiovascular and cerebrovascular diseases. Therefore, it can be used as a This natural pigment resource is used in industries such as food, pharmaceutical and cosmetics. The test results show that the content of anthocyanins in blueberries is higher than that of all other fruits and vegetables, ranking first. Therefore, blueberries are good raw materials for extracting natural anthocyanins. [0003]...
