A two stage, on-demand, commercially-viable method for producing process cheese or process cheese-type products by the direct conversion of milk is provided. This method does not require fermentation, enzymatic treatment, and/or intermediate steps of forming and separating curds and whey. In the first stage, a powdered milk protein concentrate is form by ultrafiltering liquid milk, preferably skim milk, and then spray drying the concentrated ultrafiltered milk. The powdered milk protein concentrate, which is storage-stable, may be converted to process cheese or process cheese-type product immediately or may be stored for later conversion. The powdered milk protein concentrate can be used to produce fat-free, reduced-or low-fat, and/or full-fat cheeses having similar organoleptic properties to cheeses prepared from conventional curds and whey processes. The present two stage process is especially adapted for semi-continuous or continuous manufacture of process cheese-type products. The present two stage process is especially adapted for on-demand manufacture of process cheese or process cheese-type product since the milk protein concentrate can be stored for later conversion to cheese product. By converting the milk to a storage-stable milk protein concentrate, the manufacturing of cheese products is uncoupled from, and is independent of, the milk supply.

Continuous on-demand manufacture of process cheese

A low fat, high moisture peanut butter composition containing from 0 to 50% peanut flour having less than about 1% peanut oil and from 0 to about 50% of a fat containing peanut source selected from the group consisting of peanut paste from non-defatted peanuts having about 50% peanut oil and partially defatted peanut paste having from about 12% to about 30% peanut oil. The peanut flour and peanut paste are present in the composition at a level sufficient to provide from about 10% to about 24% of peanut protein. The composition also optionally includes from 0 to about 10% of a protein source selected from the group consisting of whey protein isolate, peanut protein isolate and whey protein concentrate. The peanut butter composition has from about 23% to about 40% moisture. The peanut butter composition also includes a humectant and emulsifier system comprising sorbitol, lecithin, glycerine, sodium stearoyl lactylate, xanthan gum and may optionally include polyphosphate. The humectant and emulsifier system is present at a level sufficient to provide a water activity (Aw) of less than about 0.91. The peanut butter composition has from about 1% to about 25% of vegetable oil, preferably peanut oil.

Reduced fat peanut butter product and method of making

The present invention is directed to a method for making Pasta Filata cheese which has an extended shelf life. Pasta Filata curd is divided into pieces and the pieces are delivered to an auger conveyor. The curd is heated and worked in the auger conveyor while immersed in hot water to a plastic consistency as it passes through the conveyor. The plastic curd is transported through a steam injection heating zone and a static mixing zone to provide a homogeneous molten curd. The molten curd is transferred from the mixer through a holding conduit into a vacuum chamber so as to flash-cool the molten curd. The holding conduit has a diameter and length sufficient to hold the molten curd for a time and at a temperature which is sufficient to pasteurize and partially sterilize the molten curd. The holding conduit has a particular inner wall surface which is formed of a material with enhanced lubricity and reduced coefficient of friction as compared to stainless steel.
