Abstract:
A compound tea beverage was developed by using Ganoderma lucidum enzymolysis solution and black tea extract as the basic raw material and adding proper auxiliary material. The extract of Ganoderma lucidum was obtained by enzymolysis, and the black tea extract was obtained by extraction. Then, the optimum formula was obtained by single factor test and orthogonal test according to sensory evaluation standard and fuzzy mathematics evaluation method. The results showed the best formula was as follows: Ganoderma lucidum extract/black tea extract/water 42.5/22.5/35, β-cyclodextrin 3%, sugar 1.4%, maltodextrin 1.4%, sodium alginate 0.04%, D-sodium ascorbate 0.024% and CMC-Na 0.18%. Under these conditions, the sensory evaluation score of Ganoderma lucidum and black tea compound tea was the highest and shelf life could reach 120 d. 24 kinds of volatile components were identified and confirmed by gas chromatography-mass spectrometry (GC-MS). The relative contents more than 2% among them were 2-ethylhexan-1-ol (78.27%), isoamyl alcohol (9.30%), isoamyl acetate (3.88%) and undecane (2.82%). The aroma components of Ganoderma lucidum and black tea were retained in this beverage.
