Embodiment 1

[0028] A method for extracting vitamins from guava, comprising the steps of:

[0029] (1) Select fresh guava, wash it, cut it into pieces quickly, and put it in a blender;

[0030] (2) Add 1.5% acetic acid solution with a weight ratio of 35:1 to the guava in the mixer, glass beads with a diameter of 0.5mm in a weight ratio of 1:300 to the guava, feed nitrogen, and stir at 16°C 15 minutes;

[0031] (3) The slurry produced after stirring is vacuum filtered;

[0032] (4) adding in the filtrate produced in step (3) and the weight ratio of guava was 1:600 ​​gac and stirred for 2 minutes to carry out decolorization, vacuum filtration again;

[0033] (5) Vacuum freeze-drying the filtrate obtained in step (4) at -20° C. to obtain a crude vitamin product.

Embodiment 2

[0035] A method for extracting vitamins from guava, comprising the steps of:

[0036] (1) Select fresh guava, wash it, cut it into pieces quickly, and put it in a blender;

[0037] (2) Add 0.5% phosphoric acid solution with a weight ratio of 10:1 to guava in the mixer, and glass beads with a diameter of 1mm in a weight ratio of 1:100 to guava, feed helium, and stir at 10°C for 30 minute;

[0038] (3) The slurry produced after stirring is vacuum filtered;

[0039] (4) adding in the filtrate produced in step (3) and the weight ratio of guava was 1:200 gac and stirred for 5 minutes to carry out decolorization, vacuum suction filtration again;

[0040] (5) Vacuum freeze-drying the filtrate obtained in step (4) at -15° C. to obtain a crude vitamin product.

Embodiment 3

[0042] A method for extracting vitamins from guava, comprising the steps of:

[0043] (1) Select fresh guava, wash it, cut it into pieces quickly, and put it in a blender;

Abstract

The invention discloses a method for extracting vitamins from guavas. The method comprises the following steps of: (1) selecting the guavas, thoroughly cleaning the selected guavas, cutting the cleaned guavas in an extraction protective solvent, and removing seeds; (2) adding the flesh of the cut guavas and the extraction protective solvent in a vacuum pulping machine together, and pulping the guava flesh; (3) adding the pulp generated through pulping to a vacuum mixer to perform vacuum mixing; (4) filtering the materials obtained in the step (3) to obtain a filtrate, leaving the filtrate to stand for layering, and performing separation so as to obtain an organic phase; (5) adding water of which the pH is smaller than 7 to the organic phase obtained in the step (4), and performing vacuum mixing for 2 hours or more so as to obtain a solution; (6) leaving the solution to stand for layering, and performing separation so as to obtain an aqueous phase; and (7) performing vacuum concentration on the aqueous phase until the concentrated aqueous phase is dried, and performing freeze drying so as to obtain crude vitamin products. Through the adoption of the extraction method disclosed by the invention, the vitamins in the guavas can be extracted; the extraction method is simple, and is suitable for large-scale popularization and application; the content of the vitamins in extract is high.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural products, in particular to a method for extracting vitamins from guava. Background technique [0002] Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions, and play an important role in the growth, metabolism, and development of the human body. [0003] As a class of biologically active substances, vitamins are easily inactivated under conditions such as high temperature, strong acid and strong alkali. Therefore, the extraction of vitamins needs to overcome the difficult problem of its variability. Chinese patent CN201510097751 (application number) discloses a method for extracting vitamin C from papaya, which includes the following steps: (1) picking fresh papaya fruit, washing it, cutting it in an extraction protection solvent, and removing seeds; (2) Add the chopped papaya pulp...
