Key Issues and Challenges in Spice Grinding
Authors and Affiliations
This paper explores the progression of spice grinding, starting with age-old methods such as stone mills and mortar-and-pestle, and moving towards advanced equipment like hammer mills, pin mills, jet mills, cryogenic units, and superfine grinders. It describes how factors like processing temperature, moisture levels, and particle size influence the flavour, aroma, and beneficial compounds in spices. The research identifies key issues, including heat build-up that leads to the loss of volatile oils, irregular particle sizing, contamination concerns, and heavy energy usage. It also outlines recent technological advances, such as employing liquid nitrogen in cryogenic grinding to safeguard sensitive elements, using superfine milling to enhance nutrient absorption, and integrating automation for improved uniformity and hygiene.
Understanding the Key Issues and Challenges in Spice Grinding is crucial for enhancing the quality of spice products in the market.
