Poultry and egg industry (network matching map)

China is the largest egg production country in the world, but due to the technical level, egg industrialization level and residents' consumption habits and other factors, there is still a large gap in the egg processing rate between our country and the developed countries. With the adjustment of the consumption structure of poultry eggs, the scale of poultry eggs and the improvement of the level of industrialization, the market prospect of various types of poultry egg processing products is broad, and scientific and technological innovation will also promote the rediscovery of multiple functions and multiple values of poultry eggs.

Poultry eggs are not only one of the most important foods in daily diet, but also one of the few foods that are not restricted by countries, regions, nationalities, religious beliefs and seasons. Apart from fresh food, what products can poultry eggs be processed into? What is the value of discarded eggshells? How much benefit can the deeply processed eggs produce?

Poultry eggs are covered with treasures, and they are processed in a variety of ways.

Poultry eggs are high in protein, rich in phospholipids and important nutrients such as sterols and vitamins, which are indispensable nutritious food.

The processing of poultry eggs not only retains nutrition, but also provides convenient and diverse eating methods to tap more value beyond food. Ma Meihu, a professor at Huazhong Agricultural University and a post scientist in the national egg industry technology system, who has been engaged in egg processing for a long time, explained: "Poultry egg processing can be divided into early processing and intensive processing. Clean eggs are the products of the initial processing process, and egg powder and its functional egg powder, convenient egg products, functional ingredients in eggs and so on are deep processing products. "

"in a broad sense, poultry egg processing is to give ordinary poultry eggs the attribute of a commodity and let it be exchanged as a commodity, which has higher value; in a narrow sense, poultry egg processing is to change the original shape of poultry eggs and fully dig out its value." Yang Ning, chief scientist of the national laying hen industrial technology system and a professor at China Agricultural University, gave a more popular understanding.

From the poultry egg processing products, at present, China's poultry egg processing products can be divided into two categories, a total of more than 60 varieties. The first category is traditional egg products, mainly including preserved eggs, salted eggs, Marinated Egg, etc.; the second category is new egg products, mainly including liquid eggs, clean eggs, special egg powder, egg beverages and so on.

"when it comes to the processing of poultry eggs, it turns out that people basically understand that fresh poultry eggs are made into salted eggs and Marinated Egg. At present, the processing of poultry eggs includes not only these old processes, but also making full use of abandoned eggshells and egg membranes to produce new products such as lysozyme, immunoglobulin, lecithin, bioorganic calcium from eggshell, and shell membrane protein peptides through technological innovation, to achieve deep processing, which fully proves that poultry eggs are treasures all over. " Ma Mei Lake said.

The proportion of poultry egg processing has been increased to 9%, and there are still many factors restricting the development.

According to the data of the National Bureau of Statistics, by the end of 2015, the total amount of poultry eggs in China was 29.99 million tons, making it the largest egg-laying country in the world. Correspondingly, the proportion of poultry egg processing in China is only 9%.

Compared with 1% 20 years ago, this 9% has been greatly improved, indicating the rapid development of China's poultry egg processing industry. However, compared with 30% to 40% of poultry egg processing in developed countries in Europe and the United States, there is still a large gap.

Yang Ning believes that the relatively slow development of China's egg processing industry is restricted by three factors. First, the consumption of poultry eggs in China has been using the mode of direct consumption after output for a long time, unlike Europe and the United States, which often separate eggs or are used for the baking of cakes and biscuits; second, the standardization of the current market is not enough, and many enterprises have no brand awareness; third, downstream food processing enterprises are cost-sensitive, although they have introduced some foreign equipment, they are underemployed, affecting the development of the industry.

It is understood that at present, the degree of concentrated egg production and the development level of industrialization in China are relatively low, and there are almost no egg processing enterprises worth more than 2 billion yuan. In addition, many egg processing enterprises in China have low degree of mechanization, low production efficiency and serious damage in processing.

In fact, less investment in science and technology has also become a factor restricting the development of the industry. Since the Tenth five-year Plan period, China has invested a lot of funds on scientific and technological research and development of agricultural products such as grain, meat, dairy products, fruits and vegetables, but little investment in the research and development of egg processing technology.

Science and technology supports the processing industry, and a poultry egg can increase efficiency at least three times.

Shendi Agricultural Biology Co., Ltd., located in Wuhan, Hubei Province, is a famous egg processing enterprise in China. In addition to selling fresh eggs, we are trying to "squeeze" the value of an egg through a long-term cooperation with the national laying hen industry technology system. "what about the discarded eggshells after the eggs are eaten? What about the egg membrane? Now, we have all produced a series of related products. " Chairman Yang Yan told reporters that the company has made progress in lysozyme products, eggshell organic calcium, shell membrane protein peptides, liquid eggs, functional egg powder and so on.

In addition to providing consumers with safe, nutritious and delicious eggs, Yang Yan said that it is also necessary to use deep processing technology to separate egg whites and yolks and use intensive processing to squeeze the value of eggshells and whites dry. "now, the value of an egg is three or five times higher than before."

"liquid eggs, clean eggs and special egg powder are not available in our country before, and many key technologies are being localized through technology introduction, digestion, absorption and re-innovation. It can be said that 20 years of scientific and technological innovation has supported the development of the entire poultry egg industry, and egg processing products have also begun to benefit human beings in medicine, biology and other fields. " Ma Meihu lamented, "the processing technology of eggs determines the ultimate value of eggs."

Due to the joint research and development of universities, scientific research institutions and enterprises in China, China's egg processing industry has made great progress in new theories, new technologies, new technologies, new equipment, new methods, new products and standardization. The new egg processing industry is also rising rapidly, and the industrial scale has now reached 100-12 billion yuan. There are more and more egg processing enterprises like Shendi Agriculture.

The demand for poultry egg processing products is increasing, and the market prospect is broad in the future.

Due to the support of new processing technology, China has become a country with a rich variety of egg products in the world. Experts believe that, as a big consumer of poultry eggs, the consumption market of egg products has broad prospects and can be expected in the future.

According to the Analysis of the Research report on key Industries of China's Agricultural products processing Industry (2015), although about 85% of poultry eggs are still sold in the form of fresh shell eggs, with the enhancement of people's awareness of safety consumption, the production and consumption of newly processed clean eggs is growing rapidly. For traditional egg products, China has gradually begun to adopt modern production methods and technologies, the production scale is constantly expanding, food consumption is growing rapidly, the industrial scale has reached 280-30 billion yuan, and exports to other countries are also increasing; in particular, pine preserved eggs are growing rapidly. In addition, due to the promotion of new technology and market demand, special egg powder, egg beverages and egg condiments all have a very broad market prospect.

For the future poultry egg processing market, Mamei Lake is optimistic: "at present, we have at least 12 docking service enterprises, people can not do without poultry eggs and their products, the future poultry egg processing industry will be safer and healthier."

"Poultry egg processing industry is not only a sunrise industry, but also a very competitive industry. With the development of science and technology, the change of people's consumption concept and the follow-up of the food processing industry, in the future, the proportion of poultry egg processing in China will rise from 9% at the end of the 12th five-year Plan to 13% to 14% at the end of the 13th five-year Plan. The scale of the egg processing industry will become larger and larger, and the industrial concentration will continue to increase. " Yang Ning said that egg processing will move towards the specialization and scale of processing, the systematization and automation of equipment, the cleanliness and greenness of the process, the safety and health of products, and the systematization and standardization of management. In the future, the value of poultry eggs will be fully developed, and the highly processed products of poultry eggs will permeate all aspects of our lives. (our reporter Wu Pei)
