摘要:
The invention relates to a method of preparing a double emulsion comprising a) preparing an emulsion comprising at least two liquid phases by bringing a first polymer (A) and a second polymer (B) into contact with each other in a solvent, wherein the concentrations of the polymers are chosen such that, upon bringing them into contact, a phase separation occurs, thereby forming drops of a first liquid phase in a second liquid phase, wherein, in the first phase, the weight concentration of the polymer A (CA) is higher and the weight concentration of the polymer B (CB) is lower than the respective concentrations in the second phase; b) dispersing the emulsion in a third liquid phase, which third phase comprises the polymer A in a CA which is higher than in the second phase and the polymer B in a CB which is lower than in the second phase, thereby forming the double emulsion, comprising at least one discontinuous phase (1)—with a relatively high CA and a relatively low CB—enclosed by a surrounding phase (2)—with a relatively low CA and a relatively high CB—which discontinuous and surrounding phase are dispersed in a continuous phase (3)—with a relatively high CA and a relatively low CB; and wherein the solvent in said liquid phases is the same or the solvents are at least, in the absence of the polymers, soluble in one another or completely miscible at 25° C.

Shelf-stable products, particularly beverages, containing polyphenols and optionally sterol and/or stanol esters are disclosed. Loss of polyphenols during the heat processing of the products is prevented by reducing the pH of the product by at least 0.2 after mixing and prior to heat processing. The pH of the final beverage should be about pH 4.6 to about pH 6.8. The preferred products are low fat cocoa beverages containing at least 0.2-5 micrograms of cocoa polyphenols per gram of the beverage.

The present invention relates to the improvement of food items through the increased utilization of plant-derived stearidonic acid. Many long chain fatty acids have been classified as being Omega 3 and have been shown to provide several health benefits, including heart health. According to the current invention plant-derived stearidonic acid (18:4ω3) has been incorporated into a wide range of food products by using either oil or flour processed from soybeans with enhanced levels of stearidonic acid. These foods range from oil-based products (salad dressing, mayonnaise) to dairy products (milk, cheese) to prepared foods (entrees, side dishes). In addition to improved health benefits the current invention provides food rich in Omega-3 fatty acids that have enhanced storage and/or shelf life characteristics.
摘要:
A composition comprising about 10-65 weight % of a protein particulate material, about 35-90 weight % of a lipid-containing material, and no more than small amounts of an emulsifier, can be used as a coating composition for a food product, or as an ingredient in a coating composition for a food product. When used as a coating for a snack food item such as a protein-containing energy bar, the coating can add to the nutritive value of the bar, and maintain the moisture content of the bar. A method for making the composition includes the steps of adding finely ground particulate protein matter to a fat composition with heat and high shear, then cooling the composition.

The present invention is directed to a method for producing a thermal stable whey protein beverage comprising: (a) providing an aqueous solution of at least 2% (w/w) whey proteins and having a neutral pH; then (b) heating the aqueous solution of whey proteins; then (c) cooling the aqueous solution of whey proteins; then (d) adding at least one mineral salt at a neutral pH; and then (e) heating the aqueous solution of whey protein to produce a thermal stable whey protein beverage The present invention is further directed to a method for producing a thermal stable whey protein beverage under aseptic processing conditions or pasteurization or ultrapasteurization conditions comprising: (a) providing an aqueous solution of at least 2% whey proteins and having a neutral pH; then (b) heating the aqueous solution of whey proteins; then (c) cooling the aqueous solution of whey proteins; then (d) adding at least one mineral salt to produce a thermal stable whey protein beverage. The present invention is also directed to a method for producing a thermal stable whey protein beverage comprising adding at least one anionic polysaccharide. Additionally, the present invention provides thermal stable whey protein beverages made by the methods provided herein.
摘要:
The invention relates to an apparatus for drying a liquid predominately containing solid matter of carbohydrates to a non-sticky powder. The apparatus comprises a spray drying chamber (5) in the upper part of which a spraying element (4) capable of atomizing liquid predominately containing solid matter of carbohydrates to droplets is positioned, means (6) for supplying a drying gas to the atomized droplets for partially drying thereof to moist particles, and a residence device (9) for post-crystallisation of the moist particles received from the drying chamber to a non-sticky powder. The apparatus further comprises a filter element (7) arranged internally in the spraying chamber, and means (16) for withdrawing the spent drying gas through the filter element. The apparatus is suitable for treating liquids with a high content of carbohydrates such as whey and whey permeate. Also disclosed is a process for producing non-sticky powders.

The invention is directed to a fermented and clarified nisin-containing whey and a method of making that can be used to produce a stabilized food product by adding, for example, to the pack water of fresh mozzarella cheese. The resulting stabilized food product retards or limits below detection levels the growth of toxins from pathogenic bacterial contaminants when the nisin-containing whey is added in amounts between about 10 to about 30% to the food product. The stabilized food product improves the safety of the food by retarding the growth of Listeria monocytogenes and improves the shelf life of the product by retarding the growth of gas forming bacteria such as bacteria from the Leuconostoc species.
摘要:
An improved protein beverage which may provide a relatively high protein content, ranging from about 0.01% by weight to about 15% by weight, while optionally employing a carbonation concentration between about 0.1 volumes of carbonation (per volume of liquid drink) to about 6 volumes of carbonation. Preferably the protein is a protein, such preferably as whey protein, or others. The protein beverage may contain juice and/or an additive which provides energy generation enhancement. The protein beverage may be heat treated to inactivate pathogenic microbes in the presence of the carbonation which may be used to provide taste and mouth feel for the drink. Typically, the treatment for pathogenic microbe inactivation is carried out in the individual package used for storage and handling of the protein drink. The protein beverage may be prepared from a protein beverage concentrate, which may be in the form of a syrup concentrate or a powder concentrate.
摘要:
The invention relates to a method for producing whey powder. In this method, whey concentrate with a dry matter content of at least 45% is heated to a temperature of at least 75, and preferably at least 85° C. before, after preliminary crystallization, being dried to a moisture content of at least 9%, in a spray-drying process. The result is a powder with reduced stickiness during drying on account of further crystallization being carried out much more quickly and more completely. The end product obtained is non-caking. The invention also relates to a device for carrying out the method, which also comprises means for treating the discharged drying gases in order to make particles entrained therein less sticky, so that a filter can be used instead of a cyclone.
