Embodiment 1

[0032] A method for extracting gardenia yellow pigment with high color valence, comprising the following technical solutions:

[0033] 1. First use 95% (V / V) ethanol to extract the gardenia fruit and carry out vacuum concentration at 60°C to 50-100 times to obtain the alcohol extraction concentrate. Use the alkaline water of electrolyzed water according to the ratio of 1:5-1:10 Ratio dissolving the gardenia yellow pigment (crocin and crocetin) in the alcohol concentrate, adjusting the power of the electrolyzed water device so that the pH value of the electrolyzed alkaline water is not lower than 8.0, thereby obtaining the water extract;

[0034] 2. A high-strength magnetic pipeline 7 with a surface magnetic field strength of 2000-6000mT is used on the pipeline where the water extract is passed into the vacuum drying tank, so that the water molecular clusters passed in become smaller, the viscosity of the water is reduced, and the vacuum drying efficiency is improved.

Embodiment 2

[0039] A high-value gardenia yellow pigment extraction method and device thereof, the specific method is: leaching the dry powder of gardenia fruit with 95% (V / V) food-grade ethanol to obtain an ethanol extract, and then extracting the ethanol extract After vacuum concentration to 50-100 times, add it to the alkaline water of electrolyzed water according to the ratio of 1:5-10, remove the upper layer of suspended solids, filter the lower layer of clear liquid to obtain a clear water extract, and inject the water extract through the high-strength magnetic tube 7 In the extraction tank, first turn on the gas circulation pump 3 of the vacuum tank, the gas heating column 11 and the negative ion generator 5, and when the temperature rises to 60°C, turn on the vacuum pump to evacuate through the air extraction port 2 until the water extract is completely dry complete. The color value of the obtained gardenia yellow pigment is 30-50% higher than the color value of the gardenia yellow...

Abstract

The invention relates to a gadenia yellow pigment extraction device and a high-color-value gadenia yellow pigment extraction method. The device comprises a vacuum drying tank, an extraction opening, a feeding device and a negative ion generation device, wherein the extraction opening is formed in the top of the vacuum drying tank, and the feeding device and the negative ion generation device are respectively arranged on the side wall; the feeding device comprises a feed inlet and a high-strong magnetic pipeline; the feed inlet is communicated with the interior of the vacuum drying tank through the high-strong magnetic pipeline; the negative ion generation device consists of a gas circulating pump, a gas heating column, a negative ion generation device and a gas guide pipe; the gas circulation pump comprises a gas inlet formed in the side wall of the vacuum drying tank; the height of the gas inlet is greater than that of the liquid inside the vacuum drying tank; the gas guide pipe extends into the vacuum drying tank from the bottom of the vacuum drying tank and is arranged below the liquid level; and the gas inlet is communicated with the gas guide pipe sequentially through the gas circulating pump, a gas heating column and the negative ion generation device. The gadenia yellow pigment extraction device has the advantages that a target product is effectively ensured not to be oxidized, no chemical reducing agents are required and the like.

Description

technical field [0001] The invention relates to an anti-oxidation extraction device and extraction method of easily oxidized natural products, in particular to a gardenia yellow pigment extraction device and a high-value gardenia yellow pigment extraction method. Background technique [0002] At present, during the extraction process of natural products, they are often exposed to extreme conditions such as high temperature and pressure, toxic solvents, oxidants, etc., resulting in some highly reducible natural products such as carotenoids, anthocyanins, and vitamins. Oxidative degradation or denaturation occurs. For example, the color value of carotenoids decreases, the absorption peak shifts purple, anthocyanins are reduced and the color weakens or fades, etc. In order to avoid some target products from being oxidized, chemical reducing agents are often added during the production process to protect the target products during the extraction process. Commonly used chemical ...
