Embodiment 1

[0022] A kind of method of extracting passion fruit peel essential oil

[0023] 1. Select 100g of fresh passion fruit peel, clean it, pulverize it with a beater, add 200mL of water and mix to obtain a slurry for use.

[0024] 2. Carry out enzymatic hydrolysis treatment to the slurry obtained in step 1. First adjust the pH of the slurry to 3, add 0.2% of the total system mass of cellulose-pectin compound enzyme (domestic cellulose pectinase is compounded at a ratio of 1:1), stir magnetically at 40°C for 2 hours, and obtain enzymatic solution A. Then adjust the pH of enzymolysis solution A to 7, add α-medium temperature amylase of 0.1% of the total mass of the total system, and stir at 65°C for 0.4h to obtain enzymolysis solution B. Finally, adjust the pH of the enzymolysis solution B to 11, add 0.05% of the total mass of the total system alkaline protease, and stir magnetically at 55°C for 0.5h to obtain the final enzymolysis solution.

[0025] 3. Ultrasonic and microwave tre...

[0028] A kind of method of extracting passion fruit peel essential oil

[0029] 1. Select 100g of fresh passion fruit peel, wash it, crush it with a beater, add 500mL of water and mix to obtain a slurry for use.

[0030] 2. Carry out enzymatic hydrolysis treatment to the slurry obtained in step 1. First adjust the pH of the slurry to 3.5, add 0.24% of the total system mass of cellulose-pectin compound enzyme (domestic cellulose-pectin enzyme compounded at 1:1), stir magnetically at 42°C for 1.8h, and obtain enzymatic solution A . Then adjust the pH of enzymolysis solution A to 7, add 0.15% of the total system mass of α-medium temperature amylase, and stir at 65°C for 0.5h to obtain enzymolysis solution B. Finally, adjust the pH of the enzymolysis solution B to 10.5, add 0.06% of the total mass of the total system alkaline protease, and stir magnetically at 55°C for 0.6h to obtain the final enzymolysis solution.

[0034] A kind of method of extracting passion fruit peel essential oil

[0035] 1. Select 100g of fresh passion fruit peel, wash it, pulverize it with a beater, add 800mL of water and mix to obtain a slurry for use.

[0036] 2. Carry out enzymatic hydrolysis treatment to the slurry obtained in step 1. First adjust the pH of the slurry to 4.0, add 0.3% of the total system mass of cellulose-pectin compound enzyme (domestic cellulose-pectinase is compounded at 1:1), stir magnetically at 46°C for 1.4h, and obtain enzymatic solution A . Then adjust the pH of enzymolysis solution A to 7, add α-medium temperature amylase of 0.2% of the total mass of the total system, and stir at 65°C for 0.6h to obtain enzymolysis solution B. Finally, adjust the pH of the enzymolysis solution B to 10.0, add 0.07% of the total mass of the total system alkaline protease, and stir magnetically at 55°C for 0.7h to obtain the final enzymolysis solution.

Abstract

The invention discloses a Passiflora edulia Sims pericarp essential oil extracting method, which comprises: crushing Passiflora edulia Sims pericarp, adding water, uniformly mixing to obtain a slurry,sequentially adding cellulose-pectin complex enzyme, alpha-medium temperature amylase and alkaline protease to the slurry to carry out enzymolysis so as to obtain a final enzymolysis liquid, inactivating, carrying out microwave ultrasonic treatment, and extracting the essential oil through water vapor distillation. According to the present invention, the extraction method has characteristics of low requirements on equipment, high extraction rate, low energy consumption, no solvent, no pollution and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a method for extracting passion fruit peel essential oil. Background technique [0002] Passion fruit, also known as egg fruit, is now cultivated in Guangxi, Fujian, Hainan, Taiwan and other places. It is a kind of aromatic fruit. Known as the "King of Juice" because of the aroma of this fruit. In the market, passion fruit is mainly used to make ice cream, drinks and candies. In the process of passion fruit processing, because the passion fruit has more skin and less pulp, a large amount of agricultural and sideline products will be produced, and 70% of the passion fruit pomace is the peel. At present, more than 4,000 tons of passion fruit peels are discarded as waste in my country every year, causing huge waste of resources and environmental pollution. [0003] The passion fruit peel is rich in amino acids, polyphenols, cellulose, pectin and essential oil...
