Abstract

Abstract A food processing component such as an enzyme extract is microencapsulated by mixing the food processing component in aqueous medium with an oleaginous material such as milk fat to form a water-in-oil emulsion and then dispersing the water-in-oil emulsion in an aqueous liquid such as milk to form a suspension of oleaginous microcapsules containing the food processing compoent. By forming microcapsules containing a cheese flavor producing enzyme extract in milk and making cheese curd from the milk, accelerated flavor production can be obtained during ripening of the cheese curd.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 101 words
A process for accelerating flavor production during cheese ripening comprising emulsifying an aqueous enzyme extract of cheese flavoring microorganism in a fluid oleaginous material-emulsifying agent mixture to produce a water-in-oil emulsion wherein the aqueous extract constitutes the discontinuous phase dispersed within a continuous phase of fluid oleaginous material, dispersing the resulting emulsion in milk to form a suspension of oleaginous microcapsules containing the aqueous extract dispersed therein, coagulating the resultant milk containing suspended microcapsules to produce a cheese curd, and curing the curd to produce cheese containing flavors generated by the extract of the cheese flavoring microorganisms contained by the microcapsules.
Claim 2
Dependent Claim 101 words
A process for accelerating flavor production during cheese ripening comprising emulsifying an aqueous enzyme extract of cheese flavoring microorganism in a fluid oleaginous material-emulsifying agent mixture to produce a water-in-oil emulsion wherein the aqueous extract constitutes the discontinuous phase dispersed within a continuous phase of fluid oleaginous material, dispersing the resulting emulsion in milk to form a suspension of oleaginous microcapsules containing the aqueous extract dispersed therein, coagulating the resultant milk containing suspended microcapsules to produce a cheese curd, and curing the curd to produce cheese containing flavors generated by the extract of the cheese flavoring microorganisms contained by the microcapsules.
Claim 3
Dependent Claim 29 words

Claim 6
Dependent Claim 45 words
The process as claimed in claim 1 in which the emulsifying to form the water-in-oil emulsion is carried out at a temperature of 15° C. above the melting point temperature of the oleaginous material but less than the boiling point temperature of the aqueous component.
Claim 7
Dependent Claim 23 words
The process as claimed in claim 1 in which the milk contains an emulsifying agent having an HLB within the range of 8-18.
Claim 8
Dependent Claim 27 words
The process as claimed in claim 6, in which the emulsifying agent is present in the milk in an amount within the range of 0.01-1% by weight.
Claim 9
Dependent Claim 29 words

Claim 13
Dependent Claim 122 words
A process for producing cheese, having an increased content of diacetyl and acetoin, comprising emulsifying an aqueous enzyme containing cell free extract from the microorganism Streptococcus lactis. subsp. diacetilactis in a milk fat-emulsifier mixture to produce a water in oil emulsion wherein the aqueous cell free extract constitutes a discontinuous phase dispersed within a continuous phase of milk fat, dispersing the resultant emulsion with agitation into skim milk to form a suspension of milk fat microcapsules containing the cell free extract dispersed therein, coagulating the resultant skim milk containing suspended microcapsules to produce a cheese curd, and curing the curd to produce cheese containing diacetyl and acetoin generated by the enzymes in the cell free extract contained by the milk fat microcapsules.
Claim 14
Dependent Claim 122 words
A process for producing cheese, having an increased content of diacetyl and acetoin, comprising emulsifying an aqueous enzyme containing cell free extract from the microorganism Streptococcus lactis. subsp. diacetilactis in a milk fat-emulsifier mixture to produce a water in oil emulsion wherein the aqueous cell free extract constitutes a discontinuous phase dispersed within a continuous phase of milk fat, dispersing the resultant emulsion with agitation into skim milk to form a suspension of milk fat microcapsules containing the cell free extract dispersed therein, coagulating the resultant skim milk containing suspended microcapsules to produce a cheese curd, and curing the curd to produce cheese containing diacetyl and acetoin generated by the enzymes in the cell free extract contained by the milk fat microcapsules.
