10mL of the fermentation product provided in example 1, each starting material and comparative example 3 was placed in a headspace bottle, 5g of sodium chloride, a magnetic rotor, 20. mu.L of internal standard (3-octanol) was added, the lid was screwed, and the mixture was shaken well. Heating and balancing in a constant-temperature water bath kettle at 60 ℃ for 30min, inserting an activated Solid Phase Microextraction (SPME) adsorption extraction head into a headspace bottle, extracting at 60 ℃ for 50min, desorbing the SPME extraction head at 250 ℃ for 3min through a gas chromatography injection port, performing GC-MS analysis (Agilent 8890-5977B), and retrieving the aroma identification result through a NIST17 mass spectrum library. The chromatograms obtained by GC-MS analysis are shown in FIGS. 1-4.
Fig. 1 to 4 show that the plant nutrient milk beverage provided in example 1 has a total of 63 identified aroma substances, including 13 esters such as ethyl butyrate, ethyl 2-methylbutyrate, butyl acetate, amyl acetate, hexyl acetate and ethyl hexanoate, 6 alcohols such as 2-methyl-1-butanol and n-hexanol, ketones and organic fatty acids. Meanwhile, the aroma substances in the plant nutrient milk beverage provided by the example 1 are increased by 16 compared with the total amount of the raw materials, and are increased by 12 compared with the beverage obtained by the traditional lactic acid bacteria fermentation method in the comparative example 3, and the plant nutrient milk beverage has typical fruit aroma and frankincense.
The types and concentrations of main aroma substances in the plant nutritional milk beverage provided in example 1 are shown in table 5.
