1. Wood grains (Wood-fibres). In genuine Kynam piece straight grains run roughly parallel, rarely see spiral grains, irregular grains and wavy grains that are available in normal agarwood (and in low grade Kynam), see Fig1.
Tip: You should use a digital microscope to magnify wood-fibres in Kynam piece and normal agarwood, see Fig2.
Fig1.…

Three main classes of essential oils in blending: an overview
Dinh xuan Ba
Borrowing the language of music, each essential oil is considered as a note, so the blend of essential oils is considered as the creation of a piece of music, a harmony in scents. Based on the evaporation rate, essential oils are classified into three classes: Top notes, Middle notes, Base notes in descending order of evaporation rate. For example shown in fig 1, peppermint evaporates faster than jasmine,…

HOW TO EVALUATE THE QUALITY OF AGARWOOD ESSENTIAL OILS
Các hợp chất có trong tinh dầu Trầm gồm 2 chủng (1):
- Các hợp chất bay hơi thường thu được qua chưng cất (distillation) ở nhiệt độ cao (95oC- 120oC). Để phát hiện và nhận dạng các hợp chất này người ta thường dùng công cụ GC-MS (Gas Chromatography-Mass Spectrometry)
- Các hợp chất nửa bay hơi và không bay hơi thường thu được qua chiết tách dung môi (solvent…

About FEI (Fungal Endophyte Inducer)
Endophytic fungi are micro-fungal endosymbionts that live within plant tissues at least in one stage of their entire life. Endophytic fungi may in some ways offer significant benefits to their host plant (Aquilaria tree, for instance) by improving and promoting plant growth, helping to reduce disease symptoms caused…

About essential waters made-in-Vietnam
What is N-in-1 homogenate:
Using sonomechanical techniques (namely ultrasonic homegenisation, no chemical used, no preservative added) N immiscible componential liquids (or powder) are stably solubilized each other for forming one end-product that is called essential water (‘Tinh thủy” in Vietnamese). Solubilized particle size can reach about hundreds nanometer. In an essential water , one liquid is stably dispersed in other liquids and in…
