Low-temperature freeze-drying technology makes "walnut yogurt" with a shelf life of up to one year

Recently, at the press conference on the innovation of Yunnan walnut industry, a new dairy product was released. The application of modern fermentation technology and modern ultra-low temperature freeze-drying technology, the development of zero-added new walnut and fresh milk deep-processed yogurt, can reach a one-year shelf life at room temperature.

The vegetable protein contained in milk and the vegetable protein contained in the walnut are 1:1 ratio, using modern fermentation technology and modern ultra-low temperature freeze-drying technology, and the zero-added new walnut and fresh milk deep-processed yogurt can be reached at room temperature. Annual shelf life... This achievement was released at the press conference on the innovation of Yunnan walnut industry held on the 11th.

The conference will focus on the “Yunnan Walnut Industry Innovation Action Plan” and the “Dali State Walnut Industry Science and Technology Innovation Action Plan”; the “Walnut Balanced Yogurt Series New Products” will be displayed; the “Walnut Forest Danshen Original Ecological Planting Technology” will be displayed; A new model for the future development of the walnut industry.

The Yunnan walnut industry innovation results conference was co-sponsored by the Dali Prefecture People's Government, Yunnan Provincial Department of Agriculture, Yunnan Provincial Forestry Department, Yunnan Agricultural University, Yunnan Plateau Characteristic Agricultural Industry Research Institute, and Beijing Huiyuan Holdings Co., Ltd. The aim is to deeply explore the quality, ecology and human value of Yunnan walnuts, highlight the advantages, comparative advantages and competitive advantages of Yunnan walnuts, build Yunnan walnut brand, enlarge and strengthen Yunnan walnut industry, and promote the development of Yunnan plateau.

As the origin of the world's deep-grain walnuts (bubble walnuts), Yunnan has more than 120 counties and cities with walnut distribution or introduction. At the end of 2016, the walnut planting area in Yunnan Province was 42.8 million mu, with a total output of 1.02 million tons and a comprehensive output value of 30.5 billion yuan. The per capita walnut income of farmers in the main walnut producing areas exceeded 1,500 yuan. Dali Prefecture, located in western Yunnan, is known as “the first city of China's walnuts”. The state's walnut planting reached 10.15 million mu. In 2017, the total output of walnuts is expected to reach 350,000 tons, accounting for 1/4 of the area in Yunnan Province. Production accounts for about one-third of the province.

“The walnut industry is the richest, most powerful and most beneficial industry in Yunnan Province,” said Sheng Jun, president of Yunnan Agricultural University. However, with the rapid growth of Yunnan walnut planting area and production, coupled with related production. The enterprises are independent and extensive management, the competition of homogenous products is fierce, and the price trend is lower. Although there are some well-known brands, the lack of intensive processing makes the Yunnan walnut industry unable to be deep, bigger and stronger.

In order to promote the healthy and sustainable development of the Yunnan walnut industry, and at the same time it can drive other characteristic agricultural industries to develop with higher quality, the Yunnan Provincial Government issued and implemented the “Yannan Province Walnut Industry Development Action Plan”. The Dali State Government and the Yunnan Agricultural University and the Yunnan Provincial Plateau Characteristic Agricultural Industry Research Institute focus on the technological innovation drive and deep processing of the walnut industry, with the core of upgrading the production, creating the second production and strengthening the three industries, with a strong “Dali 漾濞 walnut” variety. Based on the resources and base scale, it will strongly promote the development of the walnut industry in Dali Prefecture and the development of plateau characteristics.

The above-mentioned cooperation units give full play to the advantages of professional disciplines, science and technology and talents in the production, processing, sales and cultural dissemination of the plateau, and establish a walnut science and technology think tank team and research group to carry out the overall planning and research of the walnut industry chain. “Yunnan Walnut Industry Innovation Action Plan”; achieved phased results in the research and development of “new products of walnut balanced yogurt series” and “original ecological planting techniques of Danshen under walnut forest”.

"Walnut balanced yogurt series new product" not only breaks through the problem of short shelf life and short selling radius of dairy yogurt products, but also combines the nutrients of walnut to make the taste of yogurt better, the nutritional value is higher, and the consumption is more convenient. The shelf life of yoghurt at room temperature has been achieved for one year. It provides technical support for expanding the marketing scope and market space of yoghurt dairy products and using the traditional food to drive the market development of walnut products. The research and development of “new products of walnut balanced yogurt series” has promoted the development of traditional industries in Dali while promoting the development of walnut industry. Dali Prefecture is the largest dairy breeding base and dairy production base in Southwest China, with dairy production accounting for 70% of the province. “Original ecological planting techniques of Danshen under the walnut forest” explored the original ecological planting techniques of planting Salvia miltiorrhiza under the walnut forest, and received good results of 3-4 times higher than the pharmacopoeia standard and 6,000-8000 yuan per mu. The comprehensive utilization of walnut woodland has found a good development path.
