Moisture standards for hazelnuts:
Usually, international standards set the following requirements for the moisture content of hazelnuts in the shell and kernel. The moisture content of hazelnuts in the shell should not normally exceed 8%, which is important to prevent mold and other storage problems.
For hazelnut kernels, standards may vary from country to country and depending on the technology used and the type of product. Usually, the moisture content of the hazelnut kernel should be approximately in the range of 2-6%. Compliance with this standard is important for preserving the taste and quality characteristics of the product.
These requirements may vary depending on regulatory authorities and international standards. Therefore, it is recommended to always check the current standards and regulatory requirements for a specific country and type of product.
Hazelnuts are usually dried immediately after harvesting or cleaning the husk, that is, they dry the hazelnuts in the shell. Drying can be done naturally if weather conditions permit, there is storage space and workers to supervise drying. Large quantities of hazelnuts from orchards are dried in industrial dryers. This method of drying is more economically beneficial, because drying occurs quickly and without human intervention. Dryers are capable of drying from 1 ton per day.
Temperature and storage conditions:
Hazelnuts in the shell and kernel are best stored at a temperature of +1°C to +4°C. This temperature helps reduce the risk of spoilage and mold. Hazelnuts in the shell can be stored in a cool and dry place, where there is no moisture and extraneous odors.
General instructions for proper storage:
When storing hazelnuts, it is important to avoid temperature fluctuations and extreme high or low temperatures that can cause moisture to condense, as this can affect quality and shelf life. Hazelnut quickly absorbs external odors, so keep it away from substances that smell strongly, as this can affect the taste and aroma of the product.
By following the instructions for storage humidity and temperature, you can ensure that both walnuts and hazelnuts are stored for a long time, while maintaining their taste and nutritional qualities. Proper storage is an important component of the nut business, ensuring the preservation of product quality and the profitability of the enterprise.
