Abstract Cryogenic grinding of black pepper at different temperatures and feed rates was conducted, and was compared with that of conventional grinding at ambient temperature to ascertain the different quality parameters employing subjective and objective methods. The loss of volatile oil in the case of ambient grinding was about 50% as compared to cryogenic grinding.
Cold Grinding. Cold grinding – also known as cryogenic grinding or cryogenic milling – describes the process in which liquid nitrogen is added to the substances to be ground in order to achieve particularly high grain fineness with consistent quality during micronization. This process of fine grinding is mainly used for soft, flexible or ...

In this study, we compared the effects of cryogenic grinding and hammer milling on the flavour attributes of black, white, and green pepper. The flavour attributes were analysed using headspace solid-phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS), sensory evaluation and electronic nose (e-nose) analysis.
Cryogenic grinding installations are used for: Polyester […] UFP Info. Whenever fine and ultra-fine powders are produced, handled or required, processing technology from PALLMANN leads the way and sets standards with economical solutions. It is our philosophy to provide environmentally friendly systems.
The effects of cryogenic grinding on the essential oil content in black pepper have been previously reported, and their results are congruent with our findings (Murthy and Bhattacharya 2008). The piperine contents of the cryogenically ground samples derived from the black, white, and green pepper stored for 0 month were 4.15, 3.44, and 3.87 g/100 g, …

3. Add the pigment, in stages, and disperse in the normal manner. In case you want to optimize a Polymeric dispersant millbase, 4 stages are involved. The following example explaining using Avecia Solsperse products (referred to as a ladder series). Stage 1 - Calculation of % AOWP of Polymeric hyperdispersant.
Cryogenic grinding retains the product color in fenugreek powder (Meghwal and Goswami, 2014), coriander powder (Saxena et al., 2015), and black pepper powder (Ghodki and Goswami, 2016). A significant color change was observed in improved grinding under evaporative cooled grinding ( Bandara et al., 2015a ).
A pilot plant model pin mill was employed for cryogenic grinding of black pepper at different feed rates and product temperatures. These two variables had significant effects on dependent variables, viz., volatile oil, and monoterpenes and sesquiterpenes contents.
