Detailed Description of the Invention
The invention relates to edible oil-in-water cooking creams comprising about 55 to 25 93% by weight water, about 5 to 45% by weight fat, about 1 to 10% by weight protein, about 0.5 to 10% by weight starch, and an effective amount of emulsifier.
Preferably, the cream also contains an effective amount of stabilizer and an effective amount of buffer.
A "cooking cream" composition, as the term is used herein, describes a cream that 30 can be used for cooking at elevated temperatures; however, the term is not limited to creams of the invention that are used for other purposes, such as a cream used as a whip topping.
An "effective amount" of emulsifier is one that is capable of inducing the formation
of a stable emulsion. Preferably, it also improves the rate and total aeration
obtained. Preferably, the amount of emulsifier is about 0.1 to 2% by weight of the
cream. 5 An "effective amount" of stabilizer is one that is capable improving the body and
texture of toppings. Preferably, it can also reduce separation and aid in providing
freeze-thaw stability. Preferably, the amount of stabilizer is about 0.01 to 2% by
weight of the cream.
An "effective amount" of buffer is one that is capable of controlling the pH. 10 Preferably, it also increases the stability of the cream. Preferably, the amount of
buffer is about 0.05 to 2% by weight of the cream.
Preferably, a cream according to the invention comprises the following components:

(Table Removed)
The cream preferably contains about 10% to about 60% total solids, more preferably about 20% to about 45% total solids, more preferably about 30% total solids. The protein component may also be selected from numerous sources. Sources include egg proteins, non-fat dry milk (low heat), non-fat dry milk (high heat), casemates, whey protein isolates, butter milk powder, soy proteins, and milk protein concentrate. Preferred protein sources include non-fat dry milk, casemates and butter milk powder. More than one protein component may be selected as desired. The fat component may be selected from numerous sources. The term "fat" is not intended to exclude oils or to impart any meaning as to the physical state {i.e., liquid
or solid) of the component used as the fat. The fat component may be selected from plant oils, such as soybean oil, sunflower oil, canola oil, palm oil, palm kernel oil, coconut oil, safflower oil, corn oil, olive oil, peanut oil and cottonseed oil; it may also be selected from animal fats, such as, lard, tallow, and dairy fat. Combinations of more than one fat is also possible in the present invention. The fat may also be modified for use in the present invention. The possible modification includes fractionation, complete hydrogenation, partial hydrogenation and interesterification. Such modifications are well known in the art. The stabilizer may also be selected from numerous sources. Sources include carageenan, locust bean gum, guar gum, xanthan gum, sodium alginate, carboxy methylcellulose, hydroxy propyl methyl cellulose, hydroxy propyl cellulose and modified cellulose. Preferred stabilizer sources include guar gum, locust bean gum and xanthan gum.
Numerous emulsifiers may be used in the present invention. Preferred emulsifiers include sucrose esters, propylene glycol alginate (PGA), polysorbate 60, polysorbate 65, polysorbate 80, lecithin, steryl lactalates, monoglycerides, diglycerides, polyglycerides, sorbitan monosterate and diacetyl ester of tartaric acid. As is demonstrated in the examples given below, it is often preferable to use more than one emulsifier.
The starch component may also be selected from numerous sources. Sources of starch include corn, potato, maize, wheat, rice, tapioca and sorghum. One of ordinary skill in the art will appreciate that it is common practice to modify starches to enhance characteristics such as storability or purity. More than one starch may be used in the present invention.
Numerous buffers may also be used in the present invention. Preferred buffering salts include disodium phosphate, dipotassium phosphate, disodium hexaphosphate, and sodium citrate. More than one buffer may be used in the present invention. In one embodiment of the invention, the cream is used as a cooking cream. In this embodiment, the invention is stable at about 90°C for at least 5 minutes, preferably at least 10 minutes. The cooking cream is not only stable at high temperatures as an end-product, but also as it is being processed. The cooking cream is able to withstand an ultra high temperature (UHT) treatment of about 280-290°F. Production using UHT increases many favorable attributes, such as a longer shelf
life. It should be apparent that the present invention may be made using means other than UHT, such as pasteurization, but may not have a marked increase in attributes.
In another embodiment of the invention, the cream is used as a whip topping. This aspect of the invention may consist of abase composition that is substantially free of sugar. Alternatively, the whip topping could contain sugar or other sweeteners. For the base composition, it is envisioned that consumers would add sugar to achieve desired sweetness and the whipped product would preferably have an overrun of at least about 180%, preferably at least about 210%. More preferably, the topping is capable of an overrun of about 210-290%.
There are numerous components whose levels and types may be changed or added to the present invention to tailor it to the desires of the end user. Such components include emulsifiers to control overrun and whipping time, stabilizers to stabilize the emulsion and to achieve the desired texture, starch to give consistency to the cream, proteins for the dairy flavor and emulsification and buffer to control pH. pH is preferably maintained in the range of about 5-8, preferably 6.5-7. hi a preferred embodiment, the present invention is also either free of, or substantially free of, dairy fat.
