Processing Of Spices in the Food Industry: A Review of Roasting, Grinding, and Temperature Control System

1. ABSTRACT: Spices being an integral part of food industry contributes to food flavour,aroma,color,and health promoting properties.Spices are majorly used in culinary tradition word wide.The quality of spice products depends on roasting and grinding,post harvest processing.Roasting enhances the flavour and alters the chemical structure according to the temperature and time,which influences the antioxidant property and sensory characteristics in spices.Lack of control leads to loss of volatile compound,degradation of bio-active compounds,non uniform practical size and decreased shelf life.Grinding reduces the particle size for even consistency, which is further more enhanced by sieving. The traditional spice processing is commonly practice in small scale industry and household operations,that are performed manually resulting in reduced quality,inconsistent product,high labour requirement.As consumer demand increases the need for standardized and high quality product becomes necessary,thus adopting automated system.Cryogenic and low temperature grinding are the advanced method which reduces the heat damage,preserves essential oil,maintains the overall property. This review emphasis on spice roasting and operations including time and temperature control in roasting,grinding operation.It also highlights the need for automation to enable precise processing parameters,thereby improving the efficiency and consistency. It also helps understanding traditional and modern spice processing technologies ensuring efficiency.
