The invention discloses a method for extracting citrus pericarp essential oil, which comprises the following steps: selecting fresh citrus pericarps, removing the white pericarp layer until the pericarp thickness is 0.1-0.2cm, mincing, repeatedly freezing and thawing for 2-5 times, preparing a compound enzyme from pectinase and cellulose at a mass ratio of (1-6):1, preparing an enzyme solution, mixing the pretreated citrus pericarp particles with the compound enzyme solution, and performing enzymolysis in a dark place for 5-30min; and performing condensation and reflux extraction of the hydrolyzed citrus pericarps with n-hexane, and removing n-hexane to obtain essential oil. The method disclosed by the invention adopts a physical process of repeated freezing and thawing to conduct initialbreak of cell walls of citrus pericarps, and then performs enzymolysis of the citrus pericarps with the compound enzyme, so as to greatly increase the extraction rate of citrus pericarp essential oil. The method also has the following advantages: the extraction process is simple, the natural fragrance is less damaged, and the use value of the citrus processing byproduct - citrus pericarps - can be utilized to a maximum extent. The essential oil extracted using the method disclosed by the invention has pure texture and has the natural fragrance of citrus fruits.

The invention discloses application of CsLYK gene and an encoded protein thereof in improving resistance to citrus canker. The encoded protein of the CsLYK gene is a citrus LysM-like receptor proteinphosphokinase, and is named CsLYK protein. The nucleotide sequence of the CsLYK gene is a nucleotide sequence shown in SED ID No. 1; the protein sequence of the CsLYK gene is an amino acid sequence shown in SED ID No. 2. The invention also protects a breeding method of citrus resisting bacterial canker, and the method comprises following steps of integrating a citrus LysM-like receptor protein phosphokinase-encoding gene into a citrus through an overexpression vector to effectively improve citrus resistance to bacterial canker. The invention has great application value for breeding of citrus resisting bacterial canker; thereby laying the foundation of genetic breeding of citrus resisting canker, and vigorously promoting the development and application of citrus resisting canker genetic engineering.

Extraction of flavonoid citrus extract from the by-product of a juice extraction process, to provide a flavonoid-rich citrus extract is disclosed. The extraction process reduces the level of limonin and / or bitterants in the by-product extract without affecting the level of naturally occurring flavonoids, which may be added to citrus-base or non-citrus-based beverages, or used as a stand-alone juice.

Juss. thereof which can be combined with pharmaceutically acceptable carriers or diluents to be administered in the form of conventional dental compositions. The compositions of the present invention, also preferably, contain Mint.

A probiotic fruit juice drink consisting of at least one species of probiotic bacteria chosen from Lactobacillus and at least one gas formation reducer chosen from acerola, pomegranate, cranberry, arqnia, blackcurrant, buckthorn or elderberry and any combination thereof and a primary fruit juice chosen from a citrus fruit juice or an pip fruit juice. The probiotic juice drink contains optionally a secondary fruit juice and optionally water.

The invention provides an sgRNA sequence for targeted knockout of an FcMYC2 gene, a CRISPR / Cas9 vector and an application thereof , and relates to the technical field of plant genetic engineering. ThesgRNA sequence comprises FcMYC2sgRNA-1 or FcMYC2sgRNA-2. The sgRNA sequence is used to construct a CRISPR / Cas9 vector. Finally, citrus epicotyl is transformed with the CRISPR / Cas9-containing vector to obtain a plant of which FcMYC2 gene is edited and protein function is knocked out. The method has the advantages that the sgRNA targeting property is good; the FcMYC2 gene cutting efficiency is high; homozygous edited plants can be obtained from citrus types such as sweet oranges and kumquats; and therefore a powerful tool is provided for further researching and regulating a citrus essential oilsynthesis mechanism.

The invention relates to a dual-component coating film fresh keeping agent for citrus fruits. The fresh keeping agent comprises an A component and a B component, wherein the A component comprises thefollowing components in percentage by mass of 1%-5% of low molecular weight chitosan, 2%-10% of plant extracts, 0.5%-2% of sorbitol, and the balance distilled water; and the B component comprises thefollowing components in percentage by mass of 0.5%-3% of high molecular weight chitosan, 0.1%-2% of citric acid, 0.2%-3% of a propolis extract and the balance distilled water. An application of the dual-component coating film fresh keeping agent for citrus fruits comprises the following steps of performing cleaning: cleaning fresh fruits which a freshly picked, removing surface impurities and performing draining; coating films: performing coating film treatment on the cleaned fresh fruits with the dual-component coating film fresh keeping agent for citrus fruits in manners of soaking or sprinkling,; and performing air drying: air drying the fresh fruits after coating film treatment, and then performing storage in a freezer. According to the obtained dual-component coating film fresh keeping agent, the raw materials and auxiliary materials, which are used, are non-toxic and pollution-free, and the problems of security risks and environmental pollution of a chemical antibacterial fresh keeping agent are solved.
