An aseptically packed long shelf-life milk product comprising about 3 mg furosine/kg milk product to about 9 mg furosine/kg milk product; a plasmin activity of 0 mol/g*h; about 0.20 g/100 ml to about 0.35 g/100 ml of native -lactoglobulin; about 0.06 g/100 ml to about 0.11 g/100 ml of -lactalbumin, and a tyrosine equivalent of most 50 mg/L after 135 days storage time.

The invention discloses a method for producing a deodorized goat/sheep milk, which method comprises purifying fresh goat/sheep milk or goat/sheep full cream, wherein the material is subjected to a carbon dioxide treatment during the purification, and the carbon dioxide treatment comprises: introducing carbon dioxide into the material, then refrigerating the material, and removing carbon dioxide. The producing method of the invention is simple, and has a good effect of removing muttony odor of goat/sheep milk. The present invention also discloses a deodorized goat/sheep milk and a deodorized goat/sheep milk product.

A low-mineral quark matrix is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step and/or a reverse osmosis step, producing a retentate R1, which represents a dairy protein concentrate, and a permeate P1, (c) subjecting the permeate P1 to an electrodialysis step, producing a salt-depleted diluate D1, (d) combining the diluate D1 with the retentate R1, (e) subjecting the combination product such obtained to heat treatment until denaturation sets in, (f) fermenting the denaturation product such obtained by the addition of starter cultures and rennet, and (g) adjusting or standardising the fermentation product such obtained to defined dry matter and protein contents.

A device and a method are for sterilization of milk from livestock such as cows, sheep or goats. The milk, prior to an irradiation with UV-C light through a light translucent barrier, is homogenized since the milk is exposed to ultrasound. The milk simultaneously to or after the homogenization is exposed to an electrical field, such as a field with changing polarity, where polarity change and field strength are chosen such that the milk in the electrical field is heated due to the milk's resistance.
