Abstract: Based on investigation of the actual production situation, an apparatus was designed and produced for quick and effective analysis of oleoresin content during production and trade. A simple and quick evaluation model of oleoresin content was established by applying the apparatus. In order to adapt for the climate features of main oleoresin production season and regions in China, two quantitative relationships between oleoresin content (%) and volume (mL) of oleoresin solution were obtained as equations as y25=4.248x-216.3 and y30=4.211x-215.3 at 25℃ and 30℃, respectively. As a result for applying the quick evaluation models and the related determination method of the oleoresin content, a national standard was established as "Evaluation method for adulterated oleoresin" to provide technical supports for standardizing the industry order, battling counterfeit and shoddy products, and rapid on-site evaluation of oleoresin.

Key words: adulterated oleoresin, oleoresin content, volume of oleoresin solution, evaluation model
