A Review of Quality Assessment and Grading for Agarwood

Agarwood is an important non-timber forest product widely used in religious and cultural activities as perfume and fragrance and as traditional medicine in Asia. The high value of agarwood and the inflated consuming market have led to constant rising of the prices. In general, the price of the agarwood is determined according to its quality, which can be divided into different grades. But up to now, there is not any standard quality grading system which could be used overwhelmingly throughout the agarwood producing, commerce and consumption. Therefore, we reviewed agarwood in diversified grading indexes, systems and methods.
