Problems solved by technology

However, due to the selection of raw materials with relatively high acidity in the processing of soft drinks, the color of such passion fruit juice is not necessarily the best. In addition, the raw materials will inevitably be damaged in the juice processing, and the impact on the color is particularly serious.
[0004] In addition, passion fruit is currently mainly processed through decoction, reflux, ultrasonic, microwave, supercritical CO 2 Extraction and other methods to extract anthocyanins, and high temperature in these methods is likely to cause denaturation of active ingredients, ultrasonic and microwave extraction methods are not easy to achieve industrial scale, and supercritical CO 2 Only suitable for extracting fat-soluble substances

Embodiment 1

[0039] Such as figure 1 , the extraction method of the passion fruit anthocyanin of the present embodiment, the steps are as follows:

[0040] (1) select passion fruit and pericarp, dry;

[0041] (2) screening, removing sundries and browning passion fruit and pericarp;

[0042] (3) crushing;

[0043] (4) Carry out normal temperature and high pressure leaching of the crushed passion fruit and pericarp mixture: the extractant is 80% ethanol solution, the weight ratio of passion fruit and pericarp mixture to extractant is 1:20, the set pressure is 150Mpa, and the time is 20min, Suction filtration, retain the filtrate;

[0044] (5) filter to obtain the passion fruit anthocyanin extract;

[0045] (6) Vacuum concentration and drying to obtain passion fruit anthocyanins.

Embodiment 2

[0047] Such as figure 1 , the extraction method of the passion fruit anthocyanin of the present embodiment, the steps are as follows:

[0048] (1) Select passion fruit and pericarp, and dry: bake at 40°C for 12 hours;

[0049] (2) screening, removing sundries and browning passion fruit and pericarp;

[0050] (3) pulverize, cross 20 mesh sieves;

Abstract

The invention discloses an extraction method of passion fruit anthocyanin. The extraction method comprises the steps of 1, choosing passion fruit and peel, and drying; 2, screening; 3, smashing; 4, conducting high-pressure extraction on the mixture of the smashed passion fruit and the peel; 5, filtrating; 6, conducting vacuum concentration and drying to obtain passion fruit anthocyanin. According to the extraction method of passion fruit anthocyanin, electric power is used, heat sources of a boiler and the like are not needed, and no waste matter and waste gases of dust, slag and the like are discharged; the solvent is recyclable in the extraction process, and no waste liquor is discharged. The extracted waste residues can also be used as a bioorganic fertilizer, and the extraction method is a fully green manufacturing technology. When passion fruit anthocyanin extracted from the method is applied in passion fruit juice drink, the passion fruit juice drink can be more natural in color, nutritional components can be more fully preserved, and the health care function of the product can be improved; moreover, the passion fruit juice drink has better antioxidation, and shelf life can be prolonged.

Description

technical field [0001] The invention relates to the fields of natural substance extraction and food soft drinks, in particular to an extraction method and application of passion fruit anthocyanin and passion fruit juice drink. Background technique [0002] Passion fruit is also known as egg fruit and Brazil nut. The main production areas in my country are Guangdong, Guangxi, Taiwan, Fujian and other provinces. Passion fruit juice is rich in nutrients and has a strong and unique fragrance. It is known as "fruit monosodium glutamate" and "king of fruit juice". Studies have found that passion fruit contains a variety of chemical components, mainly including anthocyanins, aromatic components, cyanogenic glycosides, Alkaloids, triterpenoids, oils, carotenoids, mineral elements, amino acids and polysaccharides, etc., have health benefits such as anti-oxidation, promoting blood circulation and strengthening the body, nourishing yin and kidney, refreshing and sobering up, and improv...
