基于中国核桃发展战略的核桃加工业的分析与思考
Analysis and reflection on development strategy of walnut processing industry in China
摘要
Abstract
Walnut is an important nut distributed throughout more than 50 countries and regions. The planting area of walnut in the whole world is 4 million hm2 and its yield is about 4 million tons so far. The planting area and yield of walnut in China are both maximum in the world, which is ranked the first among Chinese four dried fruits. Walnut is also a kind of important economic forest tree species in China. Walnut fruit contains rich nutrition such as linoleic acid, linolenic acid, protein, vitamins, minerals, and its unsaturated fatty acids content is more than 50%. Walnut has the reputation of the longevity fruit as it possesses good health care function. In particular, the oil content of walnut kernel can be up to 60%-70%, so walnut plays an important role in the safety of Chinese edible oil. Based on the walnut’s nutritional ingredients and economic values, Chinese government has increased the development of walnut planting, and walnut is in an unprecedented stage of development and its planting area has been growing with a rate of 10% per year. By 2020, walnut area will reach 2.67 million hm2 and its yield will reach 3 million tons in China, which maybe leads to a decline of sales volume of walnut nuts, so it is urgent to develop the walnut processing industry. In this paper, Chinese walnut resource and its development strategy, walnut nutritional values, walnut processed products and Chinese walnut processing industry’s status are described. Meanwhile, the economic benefits brought by Chinese walnut processing are analyzed. It will increase the revenue by 14.51 billion yuan and net profit by 12.85 billion yuan for enterprises if walnut can be sold 0.7 million tons, stored 0.5 million tons and processed 1.8 million tons (60% of the total production) per year. This paper presents 10 problems to be solved for walnut processing industry in China, including such aspects as increasing the policy support, improving the top-level design, implementing the industry-university-researchalliance, exploiting the processing machinery, supporting the processing enterprises, forming the industrial chain, focusing on the public products, developing the high-grade products, carrying out the in-depth theoretical study, and opening the international market. Chinese walnut processing is still in the initial stage, and it is can not meet the needs of domestic and foreign markets at present. With the expansion of the planting area of walnut, it is necessary to develop the walnut processing industry. Chinese walnut processing industry will have broad market prospect and huge development space by means of developing high-grade products under the premise of improving the quality of popular production.关键词
