Description

Selenium-enriched egg roll and processing method thereof Technical Field The invention relates to the technical field of food processing, in particular to a selenium-enriched egg roll and a processing method thereof. Background Selenium is a trace element necessary for human body, and its core physiological function is to form core components of various antioxidant enzymes (such as glutathione peroxidase), so as to play key roles of resisting oxidation, delaying senility, regulating immunity, protecting angiocarpy, supporting normal metabolism of thyroid hormone, etc. World health organization recommends that the daily selenium intake for adults be 55-70 micrograms. However, because of a wide selenium-deficient zone from northeast to southwest in China, the selenium content of soil and agricultural products in most areas is generally low, and the daily dietary selenium intake of residents is difficult to reach the recommended standard. Long-term selenium deficiency is closely related to the rising risk of keshan disease, large bone joint disease and various chronic diseases. Therefore, developing selenium-enriched foods that are safe, efficient, and acceptable to consumers has become an important research direction in the fields of nutrition and food science. Hainan is taken as the first global selenium-rich agricultural demonstration province in China, and has unique and thick natural selenium-rich soil resources, which provides non-replicable production place advantages for producing high-quality agricultural products with inherent differentiation. By taking selenium-enriched eggs as an example, the selenium content of the selenium-enriched eggs can stably reach several times or even higher than that of common eggs through a scientific feeding scheme, the selenium-enriched eggs have excellent raw material basis for developing high-end functional foods, and the quality cognition of 'nature and health' is initially established in the consumer market. However, this outstanding resource advantage has not yet been fully translated into an industrial and economic advantage. Currently, the Hainan selenium-enriched egg industry faces a typical 'primary product dilemma', wherein the product form is high and single, most of the product is directly sold in a fresh egg form, the industry chain is short, and the deep processing links are weak. This results in low added value of the product, weak risk resistance of industry, difficulty in realization of brand premium, and insufficient and amplified valuable selenium resource value in the consumer terminal through deep processing. Therefore, the method breaks through the bottleneck of deep processing technology, develops the end consumer products with market competitiveness, and is a key break for realizing the upgrading and extending of the value chain of the Hainan selenium-rich industry. The advantage of the selenium-enriched egg raw material in Hainan is matched with the wide market demand, and the selenium-enriched egg raw material is a necessary path for solving the industrial bottleneck. Throughout the current consumer market, the global and chinese egg roll market scale continues to grow robustly, while the core engine driving growth is turning from pure mouthfeel preference to a strong pursuit of health, nutrition and functionality. The market has clearly verified the trend that, for example, some emerging brands successfully open up a high-speed growing subdivision course in traditional categories by making the concept of "sugar-free" or "low GI" by the main, and some local brands successfully cut into the middle-high market by making the quality upgrade of "crisp and non-greasy" by optimizing raw materials and processes. These cases demonstrate that there is tremendous market acceptance space based on product innovation with clear health appeal or excellent quality experience. However, despite healthy surge, most of the egg roll products on the current market still stay on the basic flavor and texture competition level, and products which exclusively use essential microelements of people such as enhanced selenium and the like as core function requirements are almost blank. The method is an innovation by taking Hainan selenium-enriched eggs as raw materials, and provides a differentiated blue sea market opportunity. The selenium-enriched egg roll can meet the requirements of consumers on convenient and delicious dietetic invigoration modes, and can be positioned by functional snacks, so that the growing healthy consumption trend is directly cut in. In view of the above, a clear industrial opportunity and challenge have revealed that, on one hand, the market has a demand gap for functional healthy snacks rich in natural selenium, and on the other hand, upgrading of the Hainan selenium-rich egg industry has a need for a specific technical scheme capable of converting the advantages of raw materials into high-added-value commodities.
