Infrared heating and drying organic herbs and spices

Herbs and spices play an important role in seasoning and preserving food when it comes to the increasing demand for tasteful and aromatic food products. To prolong the shelf life of herbs and spices and retain their characteristics such as taste, aroma, colour, dehydration is a commonly used method to reduce moisture content and inhibit the growth of microorganisms of fresh plants. However, industrially dried herbs and spices production is oftentimes faced with the challenge of quality e.g. lack of fresh-like aroma characteristics when it is compared with fresh herbs and spices.
