Embodiment 1
[0046] Embodiment 1: Preparation of Pediococcus lactis high-density culture bacterial agent
[0047] (1) Preparation of seed solution: After activating the salt-tolerant Pediococcus lactis strain of the present invention, draw 10 mL of Piniang R036 seed solution and inoculate it into 3 L of MRS liquid medium, cultivate it in an incubator at 37°C for 18 hours, and the seed solution OD 610 value reaches around 2.0.
[0048] (2) Strain expansion cultivation: adopt 500L fermenter fermentation tank, 500LMRS substratum is sterilized standby, and sterilization condition is, temperature is 100 ℃, time is 60min, and the NaOH solution of 18% (w / v) is used to ferment liquid The pH was adjusted to 6.0. Then 3 L of the activated seed solution was inoculated into the above-mentioned culture medium, the culture temperature was 37° C., and the culture time was 18 h.
[0049] (3) Centrifugation and lyophilization: Centrifuge the fermented culture medium at low temperature to collect the tha...
Embodiment 2
[0051] The method that the Pediococcus lactis bacterial agent prepared in Example 1 is used to improve the quality of sweet petals, the specific steps are as follows:
[0052] 1 sweet petal prepared
[0053] (1) Hot petals: 5 kg of dried broad bean petals that have been shelled, remove impurities, add appropriate amount of boiling water to blanch for about 3 minutes, filter, and cool. The amount of boiling water added is subject to submerging the watercress.
[0054] (2) Koji making by inoculation: In terms of mass percentage, add flour with a mass of 17% of broad bean splits, add koji Shanghai brewing 3.042 with a mass of broad bean splits of 0.03‰; cultivate in a koji room with a humidity of 90% and a temperature of 37°C for 48 hours , and cultivated to turn over once every 12h.
[0055] (3) Sweet bean seed production: mix the prepared douban koji with salt water at a mass ratio of 1:1 (add salt and water at a time, and the final concentration of salt is 15%), and stir eve...
Embodiment 3
[0077] Example 3: Application of Pediococcus lactis Piniang R036 in the fermentation of high-salt dilute soy sauce fermented grains
[0078] 1. Pediococcus lactis enhanced soy sauce fermentation method
[0079] Steam the fully soaked soybeans, and after cooling, mix the cooked soybeans with flour at a mass ratio of 5:1, and add Aspergillus oryzae spore powder according to 0.03‰ of the total mass, and place the material at 35°C and a relative humidity of 90%. Cultured in an environment for 48 hours, the soy sauce koji was prepared, and the soy sauce koji was mixed with saline with a mass volume fraction of 25% according to a mass ratio of 1:3, and the Pediococcus lactis bacterial agent prepared in Example 1 was added to make Its final concentration is 10 7 CFU / g. Ferment at 30°C for 90 days, and filter to obtain soy sauce. According to the mass ratio of soy sauce fermented grains and salt water at 1:1, add salt water with a mass volume fraction of 15% to the head dregs, soak...
