Abstract:
The disclosure relates to a method for the production of fresh cheese of different types such as curd, Cream Cheese or Queso Fresco. The invention comprises the steps of pretreating milk and concentrating it by membrane filtration, such ultrafiltration, as well as heat treatment of the milk concentrate. The membrane filtration gives, as by-product, a sweet whey regardless of which fresh cheese type is produced. The present invention further includes the steps of adding coagulation agent and flavour additives to the concentrated milk. The coagulation agent is rennet and/or acid culture, depending on the fresh cheese type. The mixture is packed directly in consumer packages at a certain predetermined temperature, depending upon cheese type and the packages are subsequently held at this temperature for a certain time.
Abstract:
A process is provided for preparing fresh cheese having a Stevens value at 10 DEG C of at least 150g, a pH of 4.5-5.0, a fat content of 0-15 % and a dry matter content of at least 22 % comprising the steps of: a) causing milk to acidify to a pH of 4.5-5.0 to cause coagulation of protein; b) removing whey to obtain a curd; c) applying a heat treatment at a pH of 4.5-5.0, at a temperature of at least 65 DEG C for a period of time sufficient to increase the firmness of the resulting product, wherein the composition that is subjected to the heat treatment comprises substantially undenatured whey protein. The curd of step c) is preferably subjected to a homogenisation treatment. The product obtainable by the process has an improved texture. If it is applied to prepare low fat fresh cheese, the otherwise occurring sandiness problem, is solved.
Abstract:
Method of cheese production on the basis of ultrafiltration-concentrated milk, wherein acidified and pasteurized retentate is optionally added to the retentate from the ultrafiltrated milk, which is acidified with at least one starter culture to obtain a pH-value of from 4.5 to 5.6, whereupon salt and optionally other additives are added and the retentate is, while supplying cheese rennet, pumped into cheese moulds or ready-made packages wherein the cheese receives final treatment under heat treatment at from 18 to 65 DEG C for a period of from 4 to 36 hours.
Abstract:
In a process for producing cheese from milk, an inactive milk-clotting enzyme and optionally chymosin or another suitable proteolytic enzyme is added to the milk, optionally simultaneously with or after adding a starter culture, to form a curd, at least part of the inactive enzyme is activated, and the resulting curd is converted to the ripened cheese. The milk employed is preferably concentrated milk, and the inactive milk-clotting enzyme is preferably prochymosin.
Abstract:
A process for the production of cheese curd suitable for conversion into natural hard cheese. The process comprises (i) concentrating milk by UF to produce a retentate having a CF of 2-8 and reducing the lactose level to 1-6.2% w/w by diafiltration; (ii) ripening the retentate to produce a pH drop of 0.05-1.5 pH units; (iii) coagulating the retentate; (iv) cutting the coagulum at a time between 120% and 220% of the coagulation time without disruption of the coagulum structure; (v) cooking the coagulum to 30-50oC and holding the cooked coagulum until a suitable curd is produced, said cooking and holding being such that there is no damage to the coagulum, fusion is avoided, and syneresis is promoted, the total duration of these operations being 20-120 minutes; (vi) and separating the curd, from whey expelled during syneresis in stage (v).
Abstract:
Cheese or a cheese base is produced by concentrating milk, increasing the ionic strength of the resultant concentrate sufficient to maintain it in the liquid state during and after subsequent fermentation, fermenting the concentrate and removing water from the fermented concentrate such as by evaporation to produce cheese or cheese base containing substantially all the casein and whey proteins originally present in the milk. The fermented concentrate is preferably preheated before water removal to prevent phase separation and burn-on during water removal, and to reduce viscosity of the resultant product. A non-toxic salt such as sodium chloride may be added to increase the ionic strength. This process permits efficient removal of water from the fermented concentrate since the concentrate does not coagulate during fermentation, and the process avoids the possibility of losing whey proteins by totally eleminating syneresis.
Abstract:
The present invention relates to a method of preparing sour dairy products wherein the amount of acid whey as a by-product is considerably reduced. In particular, the sour dairy products are concentrated fermented milk products including all kinds of strained yoghurt such as Greek yoghurt, labneh and skyr, as well as fresh cheeses such as cream cheeses and quark, and other products which are concentrated after fermentation.
Abstract:
The present invention relates to a method of preparing cottage cheese wherein the amount of acid whey as a by-product is reduced and the production time in the cheese vat is reduced.
Abstract:
The present invention relates to a method for producing cheese in a container as well as a container for use in such a method. The method relates to producing 5 acidified cheeses from milk by use of ultra filtration. In the method of the invention, retentate containing rennet and culture are filled into the container and is left to coagulate in the container. After coagulation, a membrane is placed on the coagulated cheese, and salt is dosed on top of the membrane, whereupon the container is sealed. According to the invention, the membrane is impermeable to 10 liquid to ensure that no liquid will pass through the membrane. This is advantageous, in that liquid passing through the membrane will create brine when dissolving the salt on top of the membrane; this brine may pass back into the cheese curd due to osmosis, which will stop the acidification process. This problem is overcome by the method of the invention.
Abstract:
The present invention is directed to a process for making fat-containing dairy based food products such as cheese, without the use of emulsification salts and products made by the process.
