Waxy maize is a special type of corn. It comes from normal corn and above normal corn, has an independent intrinsic genetic composition, exhibits unique grain structure, nutrient composition, processing quality, and Waxy maize is a special type of corn. It is derived from normal corn and higher than normal corn. It has an independent intrinsic genetic composition and exhibits unique characteristics such as grain structure, nutrient composition, processing quality and edible flavor. It is a special kind of fruit and vegetable with good nutritional quality. Compared with ordinary corn, waxy corn has a greater use value, after processing can be added value of 300% to 400%. In recent years, people’s demand for waxy corn has been increasing. Under the control of the market economy, the cultivation and processing of waxy maize is expanding. This not only satisfies people’s ever-increasing living needs, but also brings about better growth for growers and processors. The proceeds. Local governments and people of insight have launched the production of processed waxy corn products. Therefore, it is very necessary to develop glutinous corn production and carry out deep processing to achieve large-scale production and industrialization as soon as possible.
In recent years, we have learned deeply that in order to develop the fresh corn and waxy corn industry, we must deal with several issues. If fisheries have ideal processing varieties, it will be difficult to expand the planting area and processing production scale; The processing technology and processed products are difficult for consumers to accept; without good raw materials, it is difficult to produce high-quality products; without good cultivation techniques, it is difficult to provide high-quality raw materials. To this end, we focused on the special genetic mechanism, characteristics and growth and development of waxy corn for the environment requirements and uses, using the principles and methods of systematic science, research and breeding a good palatability, high commercial quality, high yield and quality, pest resistance Illness, sweetness, fragrance, thin skin and thick flesh. The fruit and vegetable new type of waxy corn that can be eaten fresh and can be processed and used, and it is equipped with high-quality and high-efficiency cultivation technology, appropriate harvesting technology, quick-freeze fresh-keeping processing technology and vacuum packaging preservation and processing technology. All of these, after trials and demonstrations, have greatly improved farmers' planting efficiency and the efficiency of the processing factories. In particular, the processing scale has been greatly expanded, the processing period has been extended, the processing quality has been improved, the production cost has been reduced, and high The annual supply market for fresh, high-quality, waxy corn preservation products has made positive contributions to further enriching the vegetable baskets of the urban and rural people.
1. Screening of Waxy Corn Varieties (1) Breeding Adaptability of Varieties Collection of varieties, observation of planting adaptability, determination of disease resistance of the varieties and local adaptability.
(2) Variety processing adaptability During corn milk ripening, the uniform and robustly growing corn of the plant is peeled, and the varieties with good commercial character, uniform ear size, small ear tip, uniform grain arrangement, and uniform color are selected for further selection. Inspection. After 23 days to 25 days after the pollination of corn, the relevant persons were organized to taste and select the varieties with good flavor, good palatability, and less rind. The ideal yellow glutinous rice varieties include Jindan (糯) 41 (formerly Jinxianxian 1) and glutinous stick 1; White glutinous varieties of Jinxianxian No. 6, Jinxianxian 2nd, Zhongyu 1st, Su No.1 and No.1; No.8, No.8, Jinxian, etc.
2. The determination of the appropriate mining period and the post-harvest storage technology of waxy maize (1) The determination of timely harvesting at the right harvest time is the key link for the production of high-quality corn, and plays a role in the past. It is both the key to cultivation and the primary factor in processing. According to the grain water content after pollination combined with tasting to scientifically determine the appropriate harvest period: a look at the color of the filaments, the filaments from the top of the yellow to the ear of the leaves; two touch the top of the ear, the temporal leaves are slightly relaxed; three to see the fruit, fruit Grain color is normal, and the grain is full. When the milk is squeezed out, the milk is discharged from the grains, which is suitable for the harvesting period. Generally, the suitable harvest period of fresh corn is from 22 days to 24 days after pollination. At this time, the sugar content is high, the pod is good, the peel is thin, the fragrance is delicious, and the taste is the best. However, it is also necessary to combine the specific conditions of the time and local conditions. If the climate is hot and dry, the appropriate mining period should be appropriately advanced; if the temperature is low and high humidity, the suitable mining period should be extended.
(2) The main features of quality degradation after harvesting are: poor taste, reduced waxiness, reduced sugar content, thicker peel, and loss of flavor and fragrance. The appearance is characterized by wilting of loquat leaves, subsiding of green color, hardening of seed coat, serious yellowing of loquat leaves, occurrence of odor, and loss of commercial value. The main causes of deterioration in quality are storage temperature, respiratory intensity, and storage time.
(3) Fresh-keeping technology before processing after harvesting Corn can control the respiration rate of fresh corn ear by reducing the storage temperature and shortening the storage time. This can reduce the degradation rate of sugar and ensure the high quality of fresh corn. Because fresh glutinous corn is difficult to preserve and has a short shelf life, the fresh-keeping product focuses on a “fresh†and emphasizes a “fastâ€. Therefore, it is required that the raw materials be completed from harvesting to sterilizing within 8 hours, and each process must seize the time.
3. Industrial development of fresh glutinous maize (1) Focus on variety Quality The quality of the product (food quality and sensory quality) is the core of industrialization. Different types of waxy corn have different qualities. Even if they are of the same variety, if the cultivation, management, harvesting and processing technologies are different, the quality of the waxy corn is quite different. At present, the best varieties of fresh glutinous corn suitable for processing are Zhongjing No.1, No.2 No.2 Jinshangxian, No.2 Jinshangyu, No.1 Suyuyu No.1 (white) No.41 Jinjindan(糯) No.41 (original Jinxian). No.1), No.1 stick (yellow) and so on. At the same time, it is necessary to conduct checks in cultivation, management, harvesting, processing, etc., to ensure the production of high-quality products and create brand-name products.
(2) It should be market-oriented, adapt to local conditions, be adapted to the needs of the times, and not be introduced blindly to expand the scale. In China, glutinous maize can be grown in any place where corn is grown. However, its geographical environment, climate characteristics and ecological conditions determine its advantageous industrial layout. Just as a Beijing guest said it well: “Similarly glutinous corn, Shanxi's waxy corn flavor is particularly good.†This fully shows that a specific geographical environment can produce a unique flavor of waxy corn products. It is on this basis that Shanxi Province has become a famous glutinous corn production and processing base in the country. However, in some areas without market research, blindly large-scale introduction of glutinous corn processing production projects either resulted in the failure of planting and processing, or led to the unattended production of products, resulting in a large backlog of products.
(3) The new varieties must be matched with high-yield and high-quality cultivation and processing techniques. A good variety must have the matching cultivation, harvesting and processing technologies before it can fully exert the variety advantages and greatly increase the planting efficiency. Provide high-quality raw materials for production and processing, reduce product costs, thereby improving product quality and expanding market share.
(4) Promote close connection between production and sales. Waxy corn is a kind of health food with good taste and rich nutrition. It is necessary to increase propaganda and make it known to every household so that waxy corn will really reach the people's table. Producers and operators should closely cooperate with each other, with small profits and more sales, and mutual benefits.
(5) Waxy corn industrialization should pay attention to the comprehensive utilization of waxy corn processing, especially the seasonality of fresh ear processing is very strong, the time is short, but the investment in manpower, financial resources and equipment during processing is very large, and the product benefit in a short time is very good. It is difficult to maintain long-term personnel costs. Therefore, we must make full use of processing equipment to produce other products in the off-season. Shanxi Weizhou Weibao Sweet Corn Company has come out with its own way. In addition to processing and producing waxy corn during the peak season, they also processed red bean filling and smoked tea eggs in the off-season, using both equipment and human resources. One person is versatile, one machine is versatile, and a variety of products are produced in a good format.
All in all, if we want to do a good job in industrializing the development of good varieties of fresh glutinous corn, we must have high-quality, high-efficiency cultivation techniques, appropriate harvesting techniques, quick-freezing, fresh-keeping and vacuum preservation and processing technologies. Only in this way can the excellent varieties fully develop their own characteristics. To take full advantage of local natural and geographical advantages, develop local leading industries, and promote the transformation of corn from raw grain production to raw material production, which will play a positive role in promoting the research, breeding, production, development, and processing of value-added corn in China.
With characteristics such as flavor, it is a special fruit and vegetable with good nutritional quality. Compared with ordinary corn, waxy corn has a greater use value, after processing can be added value of 300% to 400%. In recent years, people’s demand for waxy corn has been increasing.

(5) Waxy corn industrialization should pay attention to the comprehensive utilization of waxy corn processing, especially the seasonality of fresh ear processing is very strong, the time is short, but the investment in manpower, financial resources and equipment during processing is very large, and the product benefit in a short time is very good. It is difficult to maintain long-term personnel costs. Therefore, we must make full use of processing equipment to produce other products in the off-season. Shanxi Weizhou Weibao Sweet Corn Company has come out with its own way. In addition to processing and producing waxy corn during the peak season, they also processed red bean filling and smoked tea eggs in the off-season, using both equipment and human resources. One person is versatile, one machine is versatile, and a variety of products are produced in a good format. All in all, if we want to do a good job in industrializing the development of good varieties of fresh glutinous corn, we must have high-quality, high-efficiency cultivation techniques, appropriate harvesting techniques, quick-freezing, fresh-keeping and vacuum preservation and processing technologies. Only in this way can the excellent varieties fully develop their own characteristics. To take full advantage of local natural and geographical advantages, develop local leading industries, and promote the transformation of corn from raw grain production to raw material production, which will play a positive role in promoting the research, breeding, production, development, and processing of value-added corn in China.
