Daylily, also known as enoki, is a nutritious vegetable that is rich in vitamins, minerals, and dietary fiber, among other things. In its fresh state, daylily is not resistant to storage and is prone to rotting and deterioration. In order to prolong the shelf life of daylily and improve its quality, processing drying is a necessary step. This article will introduce the technological process and technical points of daylily processing and drying.
First, the process flow of daylily processing and drying.
The process of daylily processing and drying includes steps such as picking, steaming, drying and packaging.
1.Pluck.
The best time to pick daylilies is in the morning or evening, when the buds are at their fullest and of the best quality. When picking, you should choose flower buds that are brightly colored, free of pests and diseases, and free of mechanical damage. The daylily after picking should be disposed of in time to avoid rotting and deterioration caused by being stacked for a long time.
2.Steamed.
Steaming is an important step in the processing and drying of daylily, and its main purpose is to kill the bacteria and enzymes in daylily, maintain its quality and prolong the shelf life. The time and temperature should be well controlled when steaming, too long or too short will affect the taste and quality of daylily. Generally, the steaming time is between 1-2 minutes and the temperature is around 95. The steamed daylily should be dried in a timely manner.
3.Dry.
Drying is another important step in daylily processing, the purpose of which is to remove excess water from the daylily and make it easy to preserve. There are various drying methods, such as natural drying, tumble drying, and vacuum drying. Different drying methods also have an impact on the taste and quality of daylily. In general, daylily after natural drying and drying has a more refreshing taste, while daylily after vacuum drying has a softer taste. When choosing a drying method, it should be selected according to the product requirements and production conditions.
4.Wrap.
Packaging is the final step in daylily processing, and its purpose is to facilitate storage and sale. Attention should be paid to hygienic conditions and tightness when packaging to prevent problems such as moisture, mildew and deterioration of the product. Generally, vacuum packaging or ordinary packaging is used, and it is selected according to product characteristics and market demand.
Second, the technical points of daylily processing and drying.
1.Raw material selection.
Choosing fresh, pest-free and mechanically damaged daylily as raw materials can improve processing quality and extend shelf life.
2.Steaming time and temperature.
The steaming time should be selected according to the quality of the raw materials and processing requirements, and the temperature should be controlled at about 95%. Steaming for too short or too long will affect the taste and quality of daylily.
3.Drying method and time.
Different drying methods have an impact on the taste and quality of daylily, which should be selected according to product requirements and production conditions. The drying time should be selected according to the quality of the raw materials and the drying method to achieve the best drying effect.
4.Packaging materials and methods.
The packaging materials should have the characteristics of hygiene, sealing, moisture-proof, pressure resistance, etc., and the packaging method should be selected according to the characteristics of the product and the market demand. Vacuum packaging can extend the shelf life, while ordinary packaging is convenient for sales and circulation.
