It is not obtained the experimental results showed that addition lactobacillus plantarum CCFM 309 prepares the resulting milk Flavor cut up to cheese To being effectively improved.And biacetyl amount and comparable 44 bacterial strain of CCFM of CGMCC No.12227 bacterial strain are produced under routine culture, addition 44 bacterial strain of CCFM prepares the resulting milk Flavor cut up to cheese and is improved, but with CGMCC No.12227 bacterium Strain is compared, and milk flavor intensity is weaker, this may be the CGMCC since the biacetyl metabolism enzyme activity difference of bacterial strain causes The biacetyl metabolism enzyme activity of No.12227 bacterial strain is lower, therefore biacetyl metabolism is slow, effectively improves the flavor of product.
(2) influence of adjunct culture inoculum concentration: 1% is pressed respectively to the adjunct culture bacterium solution inoculum concentration in embodiment 2, 8% (v/v) inoculation, other steps are constant.The experimental results showed that preparation gained, which is cut up to cheese, to be produced when inoculum concentration is 1% (v/v) Product flavor cannot be effectively improved, this may be since inoculum concentration is very little so that lactobacillus plantarum can't be dominant bacteria mass-sending The effect of waving;When inoculum concentration is 8% (v/v), preparation gained cuts that the tart flavour up to cheese product is overweight and quality is really up to the mark, seriously affects The flavor and texture of product, this is because inoculum concentration is too high to lead to produce that hyper acid causes.
Although the present invention has been described by way of example and in terms of the preferred embodiments, it is not intended to limit the invention, any to be familiar with this skill The people of art can do various change and modification, therefore protection model of the invention without departing from the spirit and scope of the present invention Enclosing subject to the definition of the claims.
