Problems solved by technology

The chemical method refers to adding antioxidants to flavors and fragrances. In addition to having good antioxidant effects, the antioxidants used in flavors and fragrances should also ensure that the antioxidants themselves are stable and will not produce harmful substances. After adding, compare them with the original flavors The sensory quality of cigarettes has no obvious effect, however, the current antioxidants still have the defect that the stability is not good enough, which affects the sensory quality of cigarettes

Abstract

The invention relates to a method for extracting polyphenol compounds from tobacco wastes and an application. The method comprises the following steps: (1) collecting the residual tobacco wastes obtained from tobacco absolute oil and essential oil extraction; (2) implementing extracting via a homogenizing method; (3) implementing reduced pressure evaporation; (4) regulating PH; and (5) washing a precipitate. The entire process (the method) provided by the invention is energy-saving and environment-friendly, and the entire process achieves waste utilization; and the extract (the polyphenol compound) is good in stability, obvious in antioxidant effect and free from adverse impact on sensory evaluation.

Description

technical field [0001] The invention relates to a method for extracting polyphenolic active compounds, in particular to a method for extracting polyphenolic compounds from tobacco waste, and also relates to its application, which belongs to the field of tobacco chemistry. Background technique [0002] Polyphenolic compounds have an important impact on the color, aroma and physiological strength of tobacco leaves, and are important indicators to measure the quality of tobacco. The polyphenols in tobacco mainly include tannins (chlorogenic acid and its derivatives), coumarins (scopolamine, scopoletin, escin) and flavonoids (rutin, quercetin, kaempferol )wait. Among them, the content of chlorogenic acid and rutin is relatively high, accounting for more than 80% of the plant polyphenol content in tobacco. Chlorogenic acid is coffee tannin, which is the dicondensate of caffeic acid and quinic acid. It has a weak fragrance and can form polyquinones under the action of polyphenol...
