Optimization of fermentation conditions of β-carotenes degradating strain HC-3 and its effect on aroma enhancement of reconstituted tobacco concentrate

  • Received Date: 2019-10-24
  • The fermentation conditions of β-carotene degrading strain HC-3 were optimized by single factor experiment and orthogonal experiment,and the fermentation liquid of strain HC-3 obtained under the optimal fermentation conditions was applied to the reconstituted tobacco concentrate to study its aroma enhancing effect.The results showed that the best fermentation conditions for β-carotene degradation were 3 g/L of NaNO3,30 g/L of sucrose,3 g/L of yeast powder and 7.0 of initial pH value.Under this condition,the degradation rate of β-carotene could reach 93.35%.After being treated by strain HC-3,the eight flavor components of dihydroactyl lactone, 4,7,9-Mega three ene-3- keton, 4- hydroxyl-β-two hydrogen damascene,9-hydroxy-4,7-Mega three ene ketene,triethyl citrate, 4- (3-hydroxyl butyl)-3,5,5- three methyl-2- cyclohexene-1- ketone,tetradecanoic acid and neophytadiene in the reconstituted tobacco concentrate were significantly increased.Compared with the untreated reconstituted tobacco concentrate,the fragrances made from the reconstituted tobacco concentrate treated by strain HC-3 had better quality,more aroma,higher aroma concentration and lower offensive odor content.
