With the increasing popularity of the Cambodian agarwood market, the problem of counterfeit goods is becoming increasingly serious. This article combines industry experience and scientific testing methods to systematically introduce the identification technology of Khmer agarwood, helping consumers avoid risks. 1、 Appearance Identification: Dual Verification of Oil Lines and Colors Oil line: The genuine Khmer agarwood oil line is naturally distributed in irregular filamentous or dotted shapes, with varying shades of color. Fake oil lines are often artificially forged, such as laser engraving or chemical dyeing, with stiff lines and uniform colors. For example, the oily lines of bodhisattvas often have a unique "eagle wing pattern", which is their distinctive feature. Color: The color of Khmer agarwood is mainly dark brown and black brown, with natural oxidation marks on the surface. Fake products with colors that are too dark (such as pure black) or too light (such as light yellow) are often dyed or soaked in oil. Texture: Genuine products have a smooth and non greasy feel, and will not leave any marks when touched repeatedly; Fake products may have residue on the hands after touching due to the presence of chemical additives. 2、 Aroma identification: a scientific method of five senses linkage First impression: Khmer agarwood has a clear and elegant aroma, sweet with a hint of acidity, and no pungent sensation. Fake goods mostly contain chemical essence, which has a strong fragrance at the first smell, but lacks a sense of hierarchy. Fine smell: The authentic aroma is long-lasting, and upon closer inspection, multiple flavors such as honey, citrus, and floral fragrance can be distinguished; Fake products have a short aroma and a single taste. Heating test: Gently touch agarwood with a hot needle, the genuine product will emit a natural and mellow aroma, while the counterfeit product may have a burnt or chemical odor. Fragrant through the bag: Place the agarwood in a sealed bag, and the authentic aroma can be emitted through the bag; Fake products are almost tasteless due to their closed aroma. 3、 Component testing: precise verification through technological means Gas chromatography-mass spectrometry (GC-MS): By analyzing the volatile components in agarwood, detect the presence of sesquiterpenes unique to Cambodian agarwood (such as agarwood spironoles). Infrared spectrum (FTIR): identify the functional groups in agarwood and judge whether there are artificial additives (such as colorants and essence). Microscopic observation: Observe the distribution of wood fibers and resin in agarwood under a microscope. Genuine resin appears in granular or block form, while counterfeit resin appears uniformly filled. 4、 Market Case: Analysis of Typical Fake Product Characteristics Compression sinking ": It is formed by compressing low-quality agarwood powder, which looks similar to Cambodian agarwood, but has a high density and a dull knocking sound. 'Draw lines and sink': Paint oil lines on ordinary wood, then soak them in chemical agents to simulate the fragrance of agarwood, but the aroma is pungent and not long-lasting. Soaking low quality agarwood in agarwood oil results in a shiny surface but a dry interior, with the aroma floating on the surface. |
