Embodiment 1

[0034] (1) First sort the pomelo to remove rotten individuals, wash the sorted pomelo with water, and then separate the peel and pulp of the pomelo after cleaning;

[0035] (2) Peel and pulp are used separately:

[0036] Active substance extraction and essential oil extraction of Huyou peel as raw material :

[0037] Add 3 times the weight of water to the peel, soak for 0.5 hours, heat to boiling and extract for 120 minutes, filter to obtain the extract and peel residue, the peel residue is set aside, and the steam generated during extraction is collected and condensed to obtain fractions. Let stand for 1 hour to separate the oil and water, collect the oil layer to obtain the primary essential oil, then add anhydrous sodium sulfate to obtain anhydrous grapefruit essential oil in the primary essential oil, the addition of the anhydrous sodium sulfate is the weight of the primary essential oil 50%; inject the extract into a vacuum decompression concentrator, and concentrate u...

Embodiment 2

[0051] (1) First sort the pomelo to remove rotten individuals, wash the sorted pomelo with water, and then separate the peel and pulp of the pomelo after cleaning;

[0052] (2) Peel and pulp are used separately:

[0053] Active substance extraction and essential oil extraction of Huyou peel as raw material :

[0054] Add 10 times the weight of water to the pericarp, soak for 4 hours, heat to boiling and extract for 10 minutes, filter to obtain the extract and pericarp residue, the pericarp residue is set aside, collect the steam generated during the extraction and condense to obtain a distillate. Leave standstill for 8 hours to separate the oil and water, collect the oil layer to obtain the primary essential oil, then add anhydrous sodium sulfate to obtain anhydrous grapefruit essential oil in the primary essential oil, the addition of the anhydrous sodium sulfate is the weight of the primary essential oil 20%; first inject the extract into the vacuum decompression concentr...

Embodiment 3

[0068] (1) First sort the pomelo to remove rotten individuals, wash the sorted pomelo with water, and then separate the peel and pulp of the pomelo after cleaning;

[0069] (2) Peel and pulp are used separately:

[0070] Active substance extraction and essential oil extraction of Huyou peel as raw material :

[0071] Add 4 times the weight of calcium hydroxide solution with a mass concentration of 0.05% to the peel, soak for 2 hours, heat to boiling and extract for 60 minutes, filter to obtain the extract and peel residue, and collect the residue generated during extraction while extracting Steam and condense to obtain fractions, the fractions were left to stand for 4 hours to separate the oil and water, collect the oil layer to obtain the primary essential oil, then add anhydrous sodium sulfate to the primary essential oil to obtain anhydrous grapefruit essential oil, the anhydrous sulfuric acid The amount of sodium added is 30% of the weight of the primary essential oil; ...

Abstract

The invention discloses a process for compressively utilizing grapefruits, which is used for overcoming the defect that a grapefruit raw material and active substances in grapefruit peel cannot be utilized effectively in the prior art. The process comprises the following steps of: (1) sorting grapefruits, cleaning and separating peel and pulp of the grapefruits; (2) extracting active substances, grapefruit essential oil and peel residues from peel serving as a raw material and preparing concentrated fruit juice from the pulp serving as a raw material; and (3) 1, preparing grapefruit jam from the peel residues and the pulp serving as raw materials; 2, preparing grapefruit juice from the concentrated fruit juice or the grapefruit jam serving as a raw material; 3, preparing grapefruit tea from the peel residues and the concentrated fruit juice serving as raw materials or the grapefruit jam serving as a raw material; and 4, preparing preserved grapefruits from the peel residues and the concentrated fruit juice serving as raw materials, the grapefruit jam serving as a raw material or the peel residues serving as a raw material. By adopting the process, different grapefruit products canbe prepared by making full use of the grapefruits, and biological active substances in the grapefruit peel are fully utilized; and the process is convenient to operate, and has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of fruit processing and utilization, in particular to a comprehensive utilization process of pomelo. Background technique [0002] Huyou fruit is beautiful, pear-shaped, spherical or oblate, and golden in color. The weight of a single fruit is about 300 grams, the thickness of the skin is about 0.6cm, the edible rate is about 70%, and the soluble solids are 11-13.2%. , high nutritional value. Its meat is plump, crisp and juicy, moderately sweet and sour, sweet and slightly bitter, fresh and delicious. It also has many pharmacological effects such as cooling and dispelling fire, antitussive and phlegm-relieving, lowering blood sugar, moistening the throat and sobering up alcohol, beautifying the skin and prolonging life, etc. It is a pure natural health food that integrates nutrition, beauty and longevity. [0003] The whole body of pomelo is a treasure. In addition to the edible fruit, its peel is rich in...
