摘要:
A stable foam of a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicular cage structure without generating a gel imparting a rubbery texture to the foam. The lamellar cage structure entraps at least a substantial portion of the gas bubbles and liquid matrix therein to retain and stabilize the gas bubbles and liquid in a sufficiently compact structure that substantially prevents drainage of the liquid matrix as well as coalescence and creaming of the gas bubbles to maintain stability of the foam even when the foam is subjected to multiple heat shocks.
摘要:
A foamed delivery system having at least two components: a foam and an additive that is associated with, carried by or delivered by the foam. The foam is a stable foam that has a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicular cage structure without generating a gel imparting a rubbery texture. The lamellar cage structure entraps at least a substantial portion of the gas bubbles and liquid matrix therein to retain the gas bubbles and liquid in a sufficiently compact structure that substantially prevents drainage of the liquid matrix and coalescence and creaming of the gas bubbles to maintain stability of the foam even when the foam is subjected to heat shock. Combined with the stable foam structure the distribution and release of the additive during application is significantly improved.
摘要:
An apparatus and process for making a foam having a controlled size distribution of gas bubbles in a liquid matrix. The invention utilizes a porous material having a controlled pore size and pore distance to produce a substantially uniform size distribution of gas bubbles; a gas pumping device for directing a flow of gas to and through the porous material to form the gas bubbles; a fluid pumping device for directing a flow of liquid matrix past the porous material and a rotating element moving in the vicinity of the membrane surface causing an additional flow to detach, collect accumulate and entrain the gas bubbles in the liquid matrix to form a foam having gas bubbles of generally uniform size and a substantially uniform gas bubble size distribution. Advantageously, the pore size and pore distance of the porous material, the gas flow from the gas pumping device, the flow field generated by the rotating element and the liquid flow from the fluid pumping device cooperate to provide gas bubbles having a mean diameter X50,0 that is less than 2-2.5 times, preferably less than 1.25-1.5 times the mean pore diameter of the membrane and to provide the foam with a gas bubble diameter distribution ratio X90,0/X10,0 that is less than 5, preferably less than 3.

摘要:
A low calorie, low fat food product of a foodstuff and a stable foam. The foam has a liquid matrix, gas bubbles and a structuring agent that forms a lamellar or vesicle cage structure without generating a gel imparting a rubbery texture. The lamellar/vesicular cage structure entraps a substantial portion of the bubbles and liquid matrix therein in a sufficiently compact structure that substantially prevents drainage of the liquid matrix and coalescence and creaming of the bubbles to maintain stability of the foam even when the foam is subjected to heat shock. The food product contains less than 0.5 grams of fat, and provides a caloric density of less than 200 kcal per each 100 ml serving of gas bubble-free liquid matrix.
摘要:
The invention describes a low temperature extrusion process and a respective device for an energy-optimized and viscosity-adapted microstructuring of frozen aerated systems like ice cream. Therewith a very finely dispersed microstructure is reached under optimized balance of viscous friction based mechanical energy dissipation (1) and transfer of dissipation heat and additional phase transition (freezing) heat (2) to a refrigerant up to very high frozen water fraction at very low temperatures. With this new process and device aerated masses are continuously frozen and optimally micro-structured under minimized/optimized mechanical energy input. The microstructure of this-like treated masses supports on the one hand preferred rheological properties which lead to improved shaping, portioning and scooping properties, even at very low temperatures, and on the other hand leads to an improved shelf life (heat shock stability) and mouth feel (e.g. creaminess, melting behavior).

A process for manufacturing milk chocolate products containing a higher than normal water content by preparing a dark chocolate containing up to 30% by weight of water, adding a milk powder suspension optionally together with seed crystals of cocoa butter or cocoa butter equivalent, and mixing under low shear. The invention also relates to high water content milk chocolate products, methods of preparing a chocolate coated ice cream article with such products and to the resulting chocolate coated ice cream articles.

摘要:
A process for preparing ice containing particles by preparing a liquid formulation that includes water, a glass transition temperature (Tg) elevating agent, a sweetener and a surfactant so that the formulation has a Tg of −5° C. to −15° C.; and spraying the liquid formulation into a cryogenicatmosphere that is at least 10° C. below the Tg of the formulation to form a frozen mass to form ice containing particles. These particles can be used for a variety of purposes but preferably are used for forming frozen ice drinks in a simple, rapid and convenient manner. This is particularly useful when a single serving of such drinks is desired as no special equipment to make the drink is required. The invention also relates to packaging for the ice containing particles and methods of making frozen ice drinks from the ice particles.
