Abstract:
PURPOSE: A manufacturing method of functional barley sour dough bread is provided to improve taste and scent from an organic acid obtained from fermentation of a lactic acid and to obtain effects of various probiotics and prebiotics. CONSTITUTION: A barley sour dough manufacturing method comprises: a step of preparing a skim milk latcit acid culturing solution by culturing lactobacillus plantanum or lactobacillus brevis in skim milk; and a step of mixing the skim milk latcit acid culturing solution with flour and barley flour to inoculate water and active yeast, and then fermenting the mixture at a temperature of 18 to 22°C. The skim milk lactic acid culturing solution is prepared by secondly culturing lactobacillus plantanum or lactobacillus brevis that is activated by firstly inoculating in a lactic acid medium. Lactobacillus plantanum or lactobacillus brevis is inoculated in skim milk and cultured at a temperature of 28 to 32°C for 46 to 50 hours. Lactobacillus plantanum or lactobacillus brevis is cultured in skim milk having a cencentrion of 11.5 to 13.5%. The step of fermenting comprises: (a) a step of mixing 5 to 10 parts by weight of the skim milk latcit acid culturing solution, 80 to 120 parts by weight of a mixture of flour and barley flour at a ratio of 1:1 part by weight culturing, 90 to 95 parts by weight of water, and 0.5 to 1.5 parts by weight of dreid yeast and culturing the mixture at a temperature of 18 to 22°C; and (b) a step of mixing 80 to 120 parts by weight of the sour dough prepared in (a), 80 to 120 parts by weight of flour, and 80 to 120 parts by weight of water and culturing the mixture at a temperature of 18 to 22°C.
