Application of cryogenics in grinding of spices for value addition:

Spice cryogenic grinding (cryo-grinding) is fairly an advanced technology and therefore there are very few units presently operating in India. To achieve an end product with retained volatile oil content, freezing and chilling are the possible modes.There is no change in fundamental principle of grinding under conventional and cryogenic conditions. Changes in quality of the material during grinding are very complex for the materials containing high amount of volatile oils and fats which are easily oxidized. Use of cryogen, such as liquid nitrogen (LN) serves dual purposes.udyamimitra.in

Market Potential Of Cryogenic Grinding Of Spice. The size of the world market for spices was estimated at USD 5.86 billion in 2019 and is anticipated to increase at a CAGR of 6.5% from 2020 to 2027. The majority of raw and processed spices are produced and exported by India. India is the world’s top producer of cumin, chili, and turmeric.Cryogenic grinding is a method in which liquid CO2 (boiling point of −195.6 °C) is used to pre-freeze the material before grinding. The reduced temperature during grinding leads to better retention of physicochemical properties, better sensory characteristics, flavor, aroma, and taste.Managing thermal damage during spice grinding

Cryogenic grinding

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.In modern spice milling, cryogenic grinding is generally used because it performs better than other methods, given that liquid nitrogen, at −195.6 °C, provides the refrigeration needed to pre-cool spices and also keeps them at a low temperature.The effect of cryogenic grinding and hammer milling on the

Cryogenic grinding, however, helps to retain more volatiles and is ideal in the case of cinnamon (Tainter and Grenis, 1993). Grinding also reduces the shelf-life of cinnamon: it renders the spice more vulnerable to spoilage because the flavours and aroma compounds are not stable and will quickly disappear.Spice cryogenic grinding (cryo-grinding) is fairly an advanced technology and therefore there are very few units presently operating in India.Application of cryogenics in grinding of spices for value addition:

Grinding of spices generates heat which leads to loss of volatile oils and production of lower quality spice powders. To overcome this, cryogenic grinding system which uses liquid nitrogen or liquid carbon dioxide is developed.Cryogenics is the study of very low temperature and its application on different materials including biological products. Cryogenics has numerous applications in space science, electronics, automobiles, the manufacturing industry, sports and musical instruments, biological science and agriculture, etc. Cryogenic freezing finds pivotal Cryogenics and its Application with Reference to Spice Grinding:
