Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with specific embodiments.

[0011] A preparation method of a composite fermented bacterial agent of Monascus and Aspergillus oryzae for improving the color of Pixian Douban is as follows:

[0012] Production of bacteria powder 1: Put 10L of culture medium of Monascus sp. in the mid-logarithmic growth phase (purchased from China Industrial Microorganism Culture Collection and Management Center, No.: CICC5041) into a 1000L fermenter for culture, culture conditions: 4.25 % sweet potato flour, 1.83% corn flour, 0.2% glycerin, 2% peptone, 0.2% ammonium nitrate, 0.20% ammonium chloride, 0.4% magnesium sulfate, 0.20% potassium dihydrogen phosphate, initial pH 5.0, fermentation temperature 30°C , After 96 hours of fermentation, the cell density in the culture medium can reach 1.89~2.52×109CFU / mL; 1% glycerin, through low temperature spray drying or carbon dioxide dry ice high activity freezing combined wit...

Abstract

The invention discloses a monascus and aspergillus oryzae composite fermented inoculant for improving the color of Pi County bean paste and a preparation method thereof. The preparation method includes the following steps: preparing first bacterial powder, inoculating 10L of a monascus strain culture solution at the middle logarithmic growth phase into a fermentation tank of 1000L for culture to obtain monascus powder with the variable count of about 109-1010CFU / g; preparing second bacterial powder, respectively inoculating 5L of an aspergillus oryzae culture solution at the middle logarithmic growth phase into the fermentation tank of 1000L for culture to obtain aspergillus oryzae powder with the variable count of about 1010-1011 CFU / g; and mixing the first bacterial powder and the second powder according to the ratio of 1: 1-1: 3, and performing vacuum packing to obtain the monascus and aspergillus oryzae composite fermentation inoculant for improving the color of the Pi County bean paste. According to the fermentation inoculant and the preparation method thereof, sensory quality is improved, flavor, unique features and nutritive values of the traditional Pi County bean paste products are maintained, and the specific health care effect of the aspergillus oryzae in the fermentation process is provided simultaneously.

Description

technical field [0001] The invention relates to a compound fermenting agent of monascus and aspergillus oryzae for improving the color of Pixian watercress and a preparation method thereof. Background technique [0002] Pixian Douban is one of the three famous Douban in Sichuan. It has the characteristics of strong spicy taste, bright red and oily, large pepper pieces, and sweet aftertaste. It is a commonly used condiment in Sichuan recipes and is known as the "soul of Sichuan cuisine". The ideal color of Pixian Douban should be reddish-brown, with oily luster, neat petals and moderate stickiness. However, in actual production, the color of Pixian Douban is not satisfactory due to the sun exposure time, rain leakage, incomplete fermentation, and some immature fermentations, which affects the sensory quality and market value of Pixian Douban to a certain extent. This problem has been plagued by the rapid development of Pixian's watercress industry. Contents of the inventi...
