As a kind of functional food, health care products are valued by consumers. Irradiation sterilization is a method that can not only limit sterilization but also ensure that the effective ingredients of health care products are not destroyed, and the irradiated health care products can promote their absorption in the gastrointestinal tract.

Most of health foods contain natural active ingredients extracted from driven and plants, which are rich in nutrients, so they are also a good matrix for microbial growth activities, which can easily lead to spoilage. The existence of any harmful microorganisms in health food will endanger health and even life, so the disinfection and sterilization of health food is very important.

At present, the domestic health food is generally used in the laminar flow clean room after packaging operation directly for the finished product, no longer disinfection and sterilization. Laminar flow clean rooms are generally more expensive, the cost of establishment is higher, and the cost of use is also higher. Compared with this, γ-ray irradiation is a simple, effective and non-polluting method of sterilization at room temperature and normal pressure with low cost, and the current research also shows that irradiation can effectively kill bacteria without adversely affecting the quality of health products.

irradiation can effectively kill the bacteria and mold in the product, and with the increase of sterilization dose, the bacteria content of the product decreases simultaneously. Within a certain dose range, the effect of sterilization can be achieved without affecting the quality index of the product. Moreover, the products after irradiation sterilization generally have good storage resistance, which can effectively improve the shelf life.

Whether it is powder, tablets, oral liquid, granules and any form of health care products, can be controlled by irradiation process parameters to achieve sterilization requirements.
