DETAILED DESCRIPTION OF THE INVENTION

The sugar alcohol composition of the present invention comprises one or more sugar alcohols. The composition comprises the defined amount of GPS-6 and may further comprise other sugar alcohols such as GPM, GPS-1, sorbitol and maltitol. According to the present invention, the sugar alcohol composition may be in any form including aqueous solution, powder, granule and syrup obtained by boil down the aqueous solution, and the granular or powdery composition are especially preferable since they are easy to handle.


According to the present invention, the cream product may be any of those obtained on the market as cream for whipping. That is, the cream product may be not only those defined as “cream” under Ministerial Ordinance on Ingredient Specifications for Milk and Dairy Products, Ministry of Health, Labor and Welfare of Japan but also cream products containing conventional emulsifier, stabilizer or the like. In addition, the cream product may be those obtained by substituting whole or a part of milk fat in cream with vegetable oil; or those obtained by mixing whole milk, reconstituted milk, modified milk or skimmed milk with milk fat and/or vegetable oil. Accordingly, the fat-and-oil fraction in the cream product may be milk fat, vegetable oil or a mixture thereof. Examples of vegetable oils used for preparing the cream product used in the present invention may include, but not limited to, cocoanut oil, palm oil, palm kernel oil, soybean oil, canola oil and corn oil.


The amount of fat-and-oil fraction in the cream product used in the present invention may be in the range preferable for whipping cream, i.e. 25-55 wt %, especially 35-50 wt %.


The cream products used in the present invention may further comprise additives known to be incorporated in conventional cream products such as flavoring agents and preservatives.


According to the present invention, a conventional whipping cream can be improved by adding the above-described sugar alcohol composition to the whipping cream or by substituting at least a part of sweeteners in the whipping cream with the sugar alcohol composition.


GPS-6 used in the present invention can be prepared by hydrogenating isomaltulose, which is obtained from sucrose by means of glucosyl transferase. It may be also prepared by hydrogenation of isomaltose, which is also obtained from sucrose. GPS-6 obtained from isomaltulose is preferable for economical reasons.


In addition to GPS-6, GPM is also produced by the hydrogenation of isomaltulose. Further, hydrogenation of trehalulose, a byproduct of isomaltose from sugar, gives GPS-1. Therefore, GPS-6, GPM and GPS-1 can be prepared by hydrogenating a mixture of isomaltulose and trehalulose, which is obtained from sucrose by means of glucosyl transferase.


The sugar alcohol composition of the instant invention comprising GPS-6 and optionally GPS-1 and GPM in the specified proportions may be prepared from thus obtained mixture of GPS-6, GPM and GPS-1 by separating the respective compound by means of a known procedure such as crystallization or chromatography, and then adjusting the proportions. The sugar alcohol composition may also be prepared from commercially available reduced isomaltulose product, such as Palatinit® (Shin Mitsui Sugar Co. Ltd., Tokyo, Japan) a product consisting essentially of approximately equimolar GPS-6 and GPM, or IsoMaltidex® (Cerestar Japan Ltd., Tokyo, Japan), in the same manner as above. The sugar alcohol composition of the invention may be prepared by simply mixing commercially available GPS-6, GPM and GPS-1 to give the above-defined proportions.


The sugar alcohol composition of the present invention comprises equal to or more than 55Wt % of GPS-6 on the dry weight basis.


According to the present invention, the sugar alcohol composition comprising GPS-6 as a main ingredient will significantly suppress liquid drainage from the whipped cream. The cream product used for manufacturing the whipping cream or whipped cream of the present invention may comprise additives which are known to be used for conventional whipping creams. For example, emulsifiers such as sucrose fatty acid ester and stabilizers such as Arabic gum. The additives may be added to the whipping cream of the present invention or a commercially available cream product containing said additives may be employed. The combined use of the sugar alcohol composition of the present invention and the additives such as emulsifiers or stabilizer may provide more stable and rich whipped cream.


The whipping cream and the whipped cream of the present invention is sweetened to a certain extent by means of the sugar alcohol composition described as above. In addition to the sugar alcohol composition, the whipping cream or whipped cream of the present invention may further comprise sweeteners other than the sugar alcohol composition to provide desired sweetness. The amount of other sweeteners may be determined based on the desired sweetness.


The present invention will be understood more readily with reference to the following examples. However, these examples are intended only to illustrate the invention and are not to be construed to limit the scope of the invention. In the following examples, “%” represent “wt %” except for otherwise specified.


EXAMPLES 1,2 AND COMPARATIVE EXAMPLES 1-5
Effect of Sugar Alcohol Composition on Stabilizing Whipped Cream

Effects of various sugar alcohol compositions and other sweeteners on stabilizing whipped cream were compared. The stability was evaluated by the liquid drainage from the whipped creams. The less the liquid drainage rate represents the more stable foam structure of the whipped cream. The sweeteners used are shown below.

(Dry weight basis. “Others” includes other sugar alcohols such as mannitol)


Example 2

GPS-6 100% (Wako Pure Chemical Industries, Ltd. Osaka, Japan)


Comparative Example 1

granulated sugar


Comparative Example 2

equimolar mixture of GPS-6 and GPM (Palatinit®, Shin Mitsui Sugar Co., Ltd., Tokyo Japan)


Comparative Example 3

GPM preparation consisting of GPS-6 9% and GPM 91% (Dry weight basis)


Comparative Example 4

crystalline maltitol (Lesys® Towa Kaseikogyo, Tokyo, Japan)


Comparative Example 5

Powdered sorbitol (Powdered Sorbitol-UENO®, Ueno fine chemicals Industry, Ltd., Osaka, Japan)


Method


Fresh cream (milk fat content: 47.0%, containing emulsifier: Meiji Tokachi Fresh 100, Meiji Dairies Corporation, Tokyo Japan) about 190 g was put in a stainless bowl (opening diameter: 21 cm) and cooled to 4° C. over iced-water bath. 21 g of the sweetener shown above was added to the cream and the mixture was beaten for 2 minutes with the electric mixer (#MK-H3, Matsushita Electric Industries Co., Ltd. Osaka, Japan) until a firm peak was acquired.


The obtained whipped cream 10 g was put in a glass funnel (diameter: 50 mm), the funnel was placed in temperature controlled chamber and kept at 25° C. A glass beaker (50 ml) was placed under the funnel and the liquid drainage was collected. The amount of liquid drainage was measured at 1, 2 and 3 hours and liquid drainage rate was calculated by the formula below:

Liquid Drainage Rate (%)=(Liquid drainage (g))/whipped cream (g))×100.

The less the liquid drainage rate represents the more stable foam structure of the whipped cream.


Result


Results are shown in Table 1. Those results are average value of two trials.


No or very little liquid drainage was observed even after 3 hours in Example 1 and 2. In comparative example 1, i.e. whipped cream admixed with granulated sugar as a sole sweetener, liquid drainage rate of more than 1% was observed after one hour. This means the whipped cream of Comparative Example 1 was unstable. In comparative examples 2-5, i.e. whipped creams with sugar alcohols other than those defined in the present invention, certain extent of liquid drainage was observed after 1 or 2 hours.
