Industrial microwave sterilization technology is an innovation with great advantages in the field of nut processing, which uses the special properties of microwaves to achieve efficient and high-quality sterilization effects. The following are its significant advantages:
1. High efficiency and fast speed, energy saving and consumption reduction:
* The processing time is extremely short (usually 1/10 of the traditional method or even shorter), which greatly improves production efficiency.
* Due to internal heating, there is less heat loss and high thermal efficiency, which can significantly save energy compared to traditional thermal sterilization (usually 30%-50% energy saving).
2. Low-temperature sterilization to maintain quality to the maximum extent:
* Due to the fast speed, the sterilization requirements can be achieved at a relatively low overall material temperature (especially combined with non-thermal effects).
* The biggest advantage: it can perfectly preserve the natural color, flavor, and crispy taste of nuts. It avoids the problems of accelerated oil oxidation, darkening of color, loss of flavor, softening of texture, or excessive burning caused by traditional long-term high-temperature treatment.
* Better preservation of heat-sensitive nutrients: such as vitamins, unsaturated fatty acids, etc., which have less loss due to short heating time.
3. Uniform and thorough sterilization:
* Penetrating heating allows the inside of the material to reach the effective sterilization temperature, overcoming the problem of large temperature difference between inside and outside and insufficient internal sterilization caused by slow heat conduction in traditional methods.
* For nuts of different sizes and shapes, uniformity is usually better than traditional methods.
4. No chemical residue, safe and environmentally friendly:
* Pure physical sterilization process, no need to add any chemical preservatives or fumigants (such as ethylene oxide), eliminating the risk of chemical residues, and the product is safer and more natural.
* No harmful gases or wastewater are discharged during the production process, which is more environmentally friendly.
5. Extend shelf life:
* It can effectively kill molds, yeasts, bacteria (including heat-resistant spores) and pathogenic bacteria (such as Salmonella, E. coli, etc.) that cause nuts to spoil, significantly extending the shelf life of the product.
The core advantage of industrial microwave sterilization technology in nut processing lies in its "high efficiency, fast speed, and low temperature preservation". It can achieve a uniform and thorough sterilization effect in a very short time by utilizing the synergistic effect of thermal and non-thermal effects, while retaining the original color, attractive flavor, crisp taste and valuable nutrients of the nuts to the greatest extent, avoiding chemical residues and significantly saving energy. This makes microwave sterilization an ideal technical choice to improve the safety of nut products, extend the shelf life, and ensure high quality and natural properties, especially for high-end nut products with high requirements for flavor, taste and nutrition.
Of course, this technology also requires precise control of parameters (power, time, temperature distribution) to prevent local overheating from causing nuts to burn or quality degradation. Selecting appropriate equipment and conducting strict process verification are the keys to successful application.
