Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A process for producing a water-in-oil emulsion of the margarine-type having an oil phase and an aqueous phase, said emulsion displaying a reduced tendency to spattering, wherein the oil phase and the aqueous phase are mixed and worked to produce a margarine, comprising adding at least 0.025% by weight of a hydrophilic finely divided metal oxide or hydrophilic finely divided metalloid oxide or mixtures thereof and at least 0.01% by weight of phosphatide to said oil phase, said oil phase consisting essentially of a fat or fat blend having a slip melting point of 30°-40° C., wherein said phosphatide and said hydrophilic metal oxide or said hydrophilic metalloid oxide or mixtures thereof are added separately to said oil phase to prevent interacting prior to introduction into said oil phase.
Claim 2
Dependent Claim
129 words
A process for producing a water-in-oil emulsion of the margarine-type having an oil phase and an aqueous phase, said emulsion displaying a reduced tendency to spattering, wherein the oil phase and the aqueous phase are mixed and worked to produce a margarine, comprising adding at least 0.025% by weight of a hydrophilic finely divided metal oxide or hydrophilic finely divided metalloid oxide or mixtures thereof and at least 0.01% by weight of phosphatide to said oil phase, said oil phase consisting essentially of a fat or fat blend having a slip melting point of 30°-40° C., wherein said phosphatide and said hydrophilic metal oxide or said hydrophilic metalloid oxide or mixtures thereof are added separately to said oil phase to prevent interacting prior to introduction into said oil phase.
Claim 3
Dependent Claim
27 words
A process according to claim 1, in which said hydrophilic metal oxide or metalloid oxide has a specific surface area of at least 130 m 2 /gram.
Claim 4
Dependent Claim
21 words
A process according to claim 2, in which said hydrophilic oxide has a specific area ranging from 200-400 m 2 /gram.
Claim 5
Dependent Claim
21 words
A process according to claim 1, in which the particle size of the hydrophilic oxide ranges from 1 to 100 mμ.
Claim 6
Dependent Claim
20 words
A process according to claim 1, in which the average particle size of the hydrophilic material ranges from 5-30 μm.
Claim 7
Dependent Claim
22 words
A process according to claim 1, in which 0.025 to 0.15% by weight of hydrophilic oxide is incorporated in the oil phase.
Claim 8
Dependent Claim
25 words
A process according to claim 1, in which the hydrophilic oxide is selected from the group consisting of silicon dioxide, aluminum oxide and magnesium oxide.
Claim 9
Dependent Claim
17 words
A process according to claim 1, in which 0.01 to 5% by weight of phosphatide is used.
Claim 10
Dependent Claim
23 words
A process according to claim 1, in which the oil phase is mixed with an aqueous phase having a pH ranging from 4.0-6.5.
