Low-Fat Dairy Coffee Whitener, Frank V. Kosikowski, Rafael Jiménez-Flores Aug 1987

Low-Fat Dairy Coffee Whitener, Frank V. Kosikowski, Rafael Jiménez-Flores

Dairy Science

A coffee whitener composition made from decreamed milk ultrafiltration retentate having its protein concentrated between about 2:1 to about 4:1 compared to the protein content of the starting milk and a minor whitening power enhancing amount is added in the form of riboflavin (a vitamin) and beta carotene (a vitamin pre-cursor) or a mixture thereof. The composition is usually in powdered form and is high in protein, low in fat and sodium and reduced in lactose and its high protein enhanced as described provided a low-fat dairy coffee whitening function approximately equal to non-diary coffee creamers.


Method For Removal Of Pharmaceutical Antibiotics From Contaminated Milks, Frank V. Kosikowski, Rafael Jiménez-Flores Aug 1987

Method For Removal Of Pharmaceutical Antibiotics From Contaminated Milks, Frank V. Kosikowski, Rafael Jiménez-Flores

Dairy Science

A method of removing penicillin G and/or pharmaceutical antibiotics which contaminated milk by:
(a) Subjecting the contaminated milk to an ultrafiltration process which produces a permeate containing the contamining antibiotic and a retentate comprising milk proteins and fats.
(b) Adding a non-antibiotic containing retentate diluting (washing) aqueous fluid including uncontaminated ultrafiltered milk permeate, uncontaminated whole milk, uncontaminated skim milk, or uncontaminated acid or sweet whey, or a mixture thereof to the retentate to dilute the retentate.
(c) Subjecting the diluted (washed) retentate to the ultrafiltration process from additional antibiotic containing permeate thereby forming a milk product comprising retentate having ...


Cloning And Sequence Analysis Of Bovine Β-Casein Cdna, Rafael Jiménez-Flores, Young C. Kang, Tom Richardson Jan 1987

Cloning And Sequence Analysis Of Bovine Β-Casein Cdna, Rafael Jiménez-Flores, Young C. Kang, Tom Richardson

Dairy Science

A bovine β-casein cDNA clone was isolated from a cDNA library prepared from mammary gland mRNA. Sequence analysis revealed 25 nucleotides (nt) of the 5′ noncoding region, 672 nt of the complete sequence coding and a 3′ region of approximately 500 nt. When the nucleotide sequence of bovine β-casein cDNA is compared to rat β-casein cDNA (5), a high degree of homology is observed in the first 100 nt corresponding to the signal peptide of the pre-β-caseins.
