This invention discloses a method for increasing the tetramethylpyrazine content in a soy sauce-flavored baijiu (a type of starter culture). The method includes adding a plant additive composed of Eucommia ulmoides leaves, Malus spectabilis leaves, Polygonum hydropiper, Astragalus membranaceus, and Angelica dahurica to the raw materials used in preparing the baijiu. The plant additive is formulated in the following proportions by dry weight: Eucommia ulmoides leaves 2-3 parts by weight, Malus spectabilis leaves 1-2 parts by weight, Polygonum hydropiper 1-2 parts by weight, Astragalus membranaceus 1-1.5 parts by weight, and Angelica dahurica 0.5-1 parts by weight. This invention provides a simple, low-cost, and naturally safe method that effectively increases the tetramethylpyrazine content in the baijiu by adding a specific combination of plant materials, thereby improving the fermentation performance of the baijiu and the final flavor quality of the baijiu.

The application discloses a SNP molecular marker related to a fruit color character of a Malus hupehensis and application thereof, and belongs to the technical field of molecular biology and plant molecular breeding. The application identifies a SNP site significantly related to the fruit color character of the Malus hupehensis, which is located at the 28,700,657 base of a No. 3 chromosome, is A or G, and is further developed into a SNP molecular marker with a nucleotide sequence as shown in SEQ ID NO. 1. A primer set for detecting the SNP molecular marker is provided. Experimental results show that the primer set provided by the application can be used to accurately and efficiently identify the fruit color of the Malus hupehensis to be tested as red or yellow at a seedling stage, and to perform molecular breeding of the Malus hupehensis. The application provides a new theoretical basis and technical means for early identification of the fruit color of the Malus hupehensis, and has the advantages of high accuracy, simple operation, high detection flux and strong universality.
