Process for producing cheese

a technology for producing applied in the field of cheese processing, can solve the problems of not revealing the treatment of milk with phospholipase, manufacturing cheese from enzyme treated milk, and high fat content of free oil/fat in a product, so as to improve the fat stability of cheese and cheese milk, enhance the stability, and improve the effect of cheese production

AI Technical Summary

Benefits of technology

There is provided a process for improving the properties of cheeses; in particular the fat stability of cheese and cheese milk is improved by the present invention. The inventor has found that enzyme treatment of cheese milk significantly enhances the stability during a heat treatment of cheese produced from said phospholipase-treated cheese milk. By the process of the invention is also provided a method for increasing the yield in cheese production.

Problems solved by technology

Free oil / fat in a product is perceived as a high fat content, and is generally undesirable.
This technology is generally not applicable in cheese production as homogenisation of the cheese milk has a negative influence on the coagulation properties of the cheese milk and on the yield as well as the taste of the cheese produced therefrom.
U.S. Pat. No. 4,861,610 does not disclose treatment of milk with phospholipase and manufacturing of cheese from the enzyme treated milk.

Phospholipase Treatment of Cream for Cheese Production

In this example cream was treated with phospholipase before combined with skim milk to prepare the cheese milk.

Raw Materials

Composition of the cheese milk:

Skim milk 0.1% fat1820mlcream38.0% fat180mlButter milk (comprising the starter culture)50mlCaCl20.4g

Enzymes: 1) Rennet (Acid aspartic Rhizomucormiehei protease—EC 3.4.23.6) dosage: 0.107 g 2) Lecitase® (pancreas-derived phospholipase A2 obtainable Novo Nordisk A / S), dosage(based on fat):0,2% (w / w)

Cheese Production

Method: The cream was treated separately with phospholipase (Lecitase®, manufactured by Novo Nordisk A / S, Denmark; dosage 0.2% (based on w / w fat content)) by incubating the mixture in a 50° C. water bath for 30 minutes. The treated cream was mixed with the skim milk to a total fat content of 3.5%(w / w) of the mix, and placed in a 33-35° C. water bath. CaCl2 was added to the 2 liter cheese milk, and starter culture (i.e. butter milk) was added, and the mix...

Phospholipase Treatment of Cream to Test the Stabilising Effect on the Cream

Method: Cream (200 g) was incubated 15 minutes at 50° C. with 3 different dosages of Lecitase® 10L, (Novo Nordisk A / S, Denmark) (dosage based on estimated fat=36%):

1. Dosage  0%2. Dosage0.2% (=0.0725% of the cream)3. Dosage1.0% (=0.36% of the cream)

After the incubation the cream was cooled to 5° C. The cream was whipped in a standardised way (Philips mixer 5 speed, the first 2 minutes run at speed 4, and speed 5 the rest of the time). 100 g whipped cream was filled into a funnel and allow to stand dripping for 1 hour at room temperature.

Samples and Results:

Sample 1 was whipped for 7 minutes and 25 seconds. About 300 ml cream. Amount of dripping after 1 hour in funnel=2,5 ml.

Sample 2 was whipped 20 minutes and no foam formation was observed. The sample became a little bit thicker, and obtained a light yellow colour.

Sample 3 was whipped for 15 minutes and no foam formation was observed. The sample...

Abstract

The present invention relates to a process for producing cheese from enzyme-treated cheese milk, and the use of the resulting produced cheese as ingredient in food products. More particularly, the present invention relates to a process for producing cheese from cheese milk treated with a enzyme selected from the group of phospholipases, in particular phospholipase A1, A2 and B. Also, the present invention relates to a process for stabilizing the fat emulsion of a milk composition, e.g. cream, and the use of such stabilized milk composition, e.g. for the manufacturing of UHT-cream or cream liquor.

Description

TECHNICAL FIELD The present invention relates to a process for producing cheese from enzyme-treated cheese milk, and the use of the resulting produced cheese as ingredient in food products. The present invention also relates to a process for stabilizing the fat in a milk composition. BACKGROUND OF THE INVENTION In cheese products, the state of the fat phase is important to the properties of the cheese. The fat phase is particularly important for the stabilisation of the cheese during production and ripening, but also for the final cheese to be used, eaten as such, or used in prepared ready-to-eat dishes e.g. pizza, toast or burgers. Also, the oiling-off properties of cheese products is an important quality parameter. Oiling-off is the tendency to form free oil upon storage and melting. Excessive oiling-off is a defect most often related to heated products wherein cheese is used, e.g. pizza and related foods (cf. e.g. Kindstedt J. S; Rippe J. K. 1990, J Dairy Sci. 73: 867-873. It ...
