Fuente: WIPO "industrial hemp" The invention discloses a baking method for improving the quality and aroma of industrial hemp and an extract thereof. The method comprises the following steps: treating an industrial hemp raw material with ammonia water, and baking in a constant-temperature and constant-humidity environment. By controlling the baking conditions, macromolecular substances such as industrial hemp plant pigment, starch and protein can be degraded to form precursors of partial aroma substances, so that the quality of the industrial hemp raw material is improved. The prepared industrial cannabis sativa extract is prominent in original plant fragrance and complete in fragrance structure, the content of an active substance CBD is increased, and the industrial cannabis sativa extract can be directly applied to tobacco products such as electronic cigarettes and has important application value.
