    A few days ago, Chuxiong City, Yunnan Province held the third annual meeting and product exhibition of the National Walnut Oil and Walnut Processing Industry Innovation Strategic Alliance with the theme of "gathering scientific and technological strength, condensing industry consensus, and helping the high-quality development of walnut industry
    ".
    At the meeting, a number of academicians, experts and scholars focused on the healthy development of China's walnut industry, advanced technology of walnut comprehensive processing, walnut oil inspection and testing and related technologies to make special reports
    .
    The conference was jointly sponsored
    by the National Walnut Oil and Walnut Processing Industry Innovation Strategic Alliance, Yunnan Forestry and Grassland Bureau, and Yunnan Science and Technology Association.

    Li Peiwu, academician of the Chinese Academy of Engineering, expounded the nutritional and health functional components of walnut oil in the report entitled "Exploring the nutritional and health functions of walnut oil to promote the high-quality development of the whole industry chain", introduced the related products and standards of walnut oil, pointed out the direction for the development of walnut oil, and gave suggestions
    for bottlenecks such as antioxidant problems that plague walnut oil processing.

    Li Peiwu stressed that the entire industry chain should cooperate in innovation to overcome the problem
    of antioxidant.
    Walnut unsaturated fatty acid content is high, easy to oxidize, walnut oil is easy to deteriorate after opening; Cultivate new natural antioxidant varieties; Analyze the oxidation mechanism of walnut oil during storage, develop new packaging materials and natural antioxidants, jointly overcome the problem of easy oxidation of walnut oil, and provide scientific and technological support
    for industrial development.
    Li Peiwu stressed that it is necessary to build a standard system for the whole industry chain before, during, after production and circulation, build a "five-in-one" standard system for the whole industry chain of national standards, industry standards, landmarks, enterprise standards and group standards, adhere to the principle of "standard adoption, non-standard creation, and full implementation", and take the standardized production of the entire industry chain as the starting point to promote the high-quality development of
    the walnut industry.

    Wang Ruiyuan, chief expert of the China Cereals and Oils Society and honorary president of the Oil and Fats Branch, introduced in detail the development status of edible oil in China at the meeting, and analyzed the problems in the development of China's walnut industry from the direction of walnut raw materials, processing and market, as well as the five directions
    that need to be worked to promote the high-quality development of the walnut industry.
    Feng Jifu, a woody oilseed expert from the State Forestry and Grassland Administration, made analysis and suggestions
    on the walnut industry.

    Professor Wang Xingguo of Jiangnan University deeply analyzed the current situation and problems
    of Yunnan walnut industry through the introduction of the key technologies and industrialization projects of the whole walnut industry chain in Yunnan Province.
    He proposed to solve the bottleneck
    of the industrialization of walnuts in Yunnan from three aspects: scientific and technological innovation, large-scale production, and the development of the entire industrial chain.

    Professor Wang Yonghua of South China University of Technology introduced the function of walnut glycediride and the process
    of enzymatic production.
    She said that walnut glycadiate not only has the same color, aroma and taste as conventional oil, but also has special physiological functions, which is an effective resource
    for walnut oil to increase added value.

    Shen Yehua, vice president of Xi'an University of Technology, proposed a new strategy
    for the analysis of vegetable oil components.
    She pointed out that the use of advanced analysis methods to systematically study the molecular composition of walnut oil, construct the material group database of the main varieties of walnut oil in China's main producing areas, and combine artificial intelligence technology to provide new ideas
    for the establishment of walnut oil markers, as well as identification and counterfeiting, functional positioning, production supervision and quality evaluation 。 According to reports, Shen Yehua's team studied walnut oil to assist in improving memory function from a multi-dimensional system, explored the dose-effect relationship and the interaction mechanism of the gut-brain axis, and preliminarily revealed the potential efficacy substances; Combined with molecular docking and deep learning technology, a new strategy for screening new types of walnut peptides to assist in improving memory was constructed, and the improvement efficacy of walnut peptides on Alzheimer's disease and the interaction mechanism of the "gut-brain axis" were studied in detail, which provided a reliable theoretical basis
    for the development of walnut-related brain health products.

    Professor Liu Yulan of Henan University of Technology explained the source, production and removal of harmful substances in the production process of
    oil and fat.
    Ning Delu, Vice President of Yunnan Academy of Forestry and Grassland Sciences, introduced in detail the development status of Yunnan walnut industry, and put forward suggestions to solve the efficient development of Yunnan walnut industry - walnut oilseed utilization, existing problems and countermeasures, and introduced in detail many local policies
    formulated by Yunnan Province for the healthy development of walnut oilseed industry.

    COFCO Engineering (Xi'an) International Engineering Co.
    , Ltd.
    introduced the double red shell kernel separation equipment developed by the company, which efficiently screens out mold kernels and black kernels in walnut raw materials, and removes the broken shell in the kernel, and the separation efficiency can reach more than 98%; The first multi-station horizontal continuous hydraulic press in China, changing the traditional walnut oil pressing form, can avoid hydraulic pressing needs to wrap cake materials, labor intensity, low production efficiency and other problems, combined with PLC automatic control system, to achieve automatic feeding and discharging continuous production
    .

    Walnut oil is rich in unsaturated fatty acids such as linolenic acid, and the development of oil oxidation retardation technology to enhance its nutritional value is of great significance
    for improving national health.
    The highly sensitive in-situ detection of plasticizers in oils and fats can eliminate the drawbacks of lagging the detection results of traditional large-scale instruments and effectively prevent the occurrence of
    excessive oil plasticizers.
    Molecular distillation removes free fatty acids and plasticizers in edible oils and fats, and plays an important role
    in edible oil refining, such as low operating temperature, short heating time, no trans fatty acid generation, and less loss of heat-sensitive substances.
    New technologies such as electron beam irradiation to assist the extraction of plant actives, walnut green peel soil amendment, heavy metal stabilizer, and special walnut shell activated carbon segmented temperature control activation and preparation have good practical application value
    .

    Cao Wanxin said that the National Key R&D Program project combined traditional enzymatic hydrolysis and molecular docking-assisted screening technology to isolate and identify anti-inflammatory polypeptides, antioxidant polypeptides, elastase inhibitory peptides and acetylcholinesterase inhibitory peptides from defatted walnut meal, and develop nootropic products
    .
    Innovative new technology of segmented temperature control activation to prepare low-ash high-quality walnut shell activated carbon, and creation of new products
    such as polyphenylaromatic hydrocarbon absorption and water purification carbon.
    Lignin-degrading bacteria and cellulose-degrading bacteria were screened, and fermented walnut green peel organic fertilizer and heavy metal stabilizer were
    developed.
