preparation example 1
[0039] Preparation example 1 culture strain
[0040]According to domestic and foreign literature data, lactic acid bacteria have many health benefits to the human body. The proven effects include improving the absorption of lactose, reducing the occurrence of diarrhea, antibacterial, lowering cholesterol, anti-cancer and enhancing immunity. Referring to the list of raw materials available for food use by the Department of Health, a total of 10 strains of lactic acid bacteria commonly used in screening were obtained from the Bioresource Collection and Research Center (BCRC) of the Taiwan Food Industry Development Institute, as shown in Table 1 below. Show.
[0041] Table 1. Ten Lactic Acid Bacteria Strains
[0042]
[0043] Take 10 per milliliter of the above 10 strains of lactic acid bacteria 4 to 10 9 Colony-forming units (colony-forming units, CFU / mL) 10 ml (ie 10 5 CFU to 10 10 CFU) were cultivated in 100mL of MRS medium, and the culture conditions were 37°C and 48 ...
preparation example 2
[0044] Preparation example 2 Miracle fruit matrix deployment
[0045] First, the pulp of the miracle fruit after the seeds are removed is freeze-dried and ground into miracle fruit powder. Preparation per unit volume is the miracle fruit aqueous solution of 0.5%, 1.0%, 1.5% and 2.0% weight (w / v), and detects that the miracle fruit aqueous solution acid-base value (pH) is respectively 3.18 (0.5%), 3.21 (1.0 %), 3.26 (1.5%), 3.33 (2.0%), its pH value is all below 3.5. Therefore, acid-base neutralization is carried out with a small amount of sodium hydroxide, so that the final pH value is 5 to 8; the preferred pH value is 6 to 7; the more preferred pH value is 6.5. Add 6.5% (w / v) milk powder (fat content is that every 100 grams of milk powder contains 28.8 grams of fat, purchased from Fenglifu TM High-quality extra-concentrated milk powder) is sterilized at 121°C for 15 minutes to obtain the miracle fruit matrix, which is uniform and free of suspension. If the pH value is not ...
Embodiment 1
[0046] Embodiment 1 Miracle fruit and lactic acid bacteria joint fermentation culture
[0047] From preparation example 1, select Lactobacillus casei 1 strain (LC1), Lactobacillus paracasei 3 strains (PC2, PC3 and PC4), Lactobacillus acidophilus 1 strain (LA1) and Streptococcus thermophilus 1 strain (SS1), take 10mL concentration is 10 8 CFU / mL to 10 9 CFU / mL (ie 10 9 CFU to 10 10 CFU) were respectively placed in 100 mL of the 0.5% (w / v) miracle fruit matrix of Preparation Example 2 and co-cultivated at 37° C. for 48 hours.
[0048] The result is as figure 2 As shown, the total number of lactic acid bacteria in each group can reach 10 8 CFU / mL or more, of which the three with higher bacterial counts are Lactobacillus paracasei PC2 with 3.1×10 9 CFU / mL, Lactobacillus paracasei PC3 is 1.9×10 9 CFU / mL and Lactobacillus casei LC1 is 2.0×10 9 CFU / mL; the two with the lower bacterial counts were Lactobacillus acidophilus LA1, which was 2.3×10 8 CFU / mL and Streptococcus the...
