Abstract

The invention relates to the technical field of essence, in particular to a gardenia extract, a preparation method thereof and application of the gardenia extract in edible essence, and the preparation method of the gardenia extract comprises the following steps: S1, raw material liquid nitrogen freezing fresh-locking pretreatment; s2, pre-soaking the raw materials; s3, primary ultrasonic-assisted extraction; s4, carrying out secondary ultrasonic-assisted extraction; s5, cold storage treatment, rough filtration and centrifugation; s6, membrane separation and purification; and S7, blending. According to the method, through liquid nitrogen freezing fresh locking, low-temperature ultrasonic-assisted extraction, membrane separation and purification and calyx trace blending technologies, the aroma authenticity, freshness, physical feeling and storage stability of the extract are remarkably improved, and high-value utilization of gardenia by-products is achieved. The prepared cape jasmine flower extract has the characteristic fragrance of fresh, full and fresh and sweet cape jasmine flowers through graded extraction of petals and calyx and trace compounding, and has good solubility and storage stability in a food system.
