This invention relates to a process of preparing a fat composition, a fat composition produced thereby, uses of the fat composition and a confectionery product comprising the fat composition.
Fats and oils are important ingredients of food products. Fats and oils are sometimes subjected to an interesterification process which randomly redistributes the fatty acid acyl residues amongst the glyceride molecules. This process can alter the physical properties of the fat or oil, such as its melting point.
Shea butter is a fat obtained from the nuts of the shea tree (Vitellaria paradoxa). Shea butter is relatively rich in stearic acid (C18:0) and oleic acid (C18:1). Shea butter is often fractionated to form shea stearin and shea olein. Shea stearin is rich in StOSt (1,3-distearoyl-2-oleoyl glyceride) and is often used as a component together with other fat components in order to produce cocoa butter equivalents. Similar to shea butter, other fats such as sal butter, mango kernel fat or kokum fat are also often fractionated to produce a stearin fraction which can be used as a component to produce a cocoa butter equivalent.
Cocoa butter equivalents (CBEs) are fat compositions that can be used in combination with cocoa butter in confectionery applications. Suitable fats which can be used to produce CBEs are palm oil, illipe butter, sal butter, shea butter, kokum fat and mango kernel fat. CBEs are in general blends of fractionated forms of these fats that have a triglyceride composition that is closer to that of cocoa butter. Thus, different fat sources are required in order to make a desirable CBE. CBEs could also be produced via enzymatic transesterification or interesterification. However, such processes are particularly complex and inefficient. Also, the products of enzymatic reactions are often not recognized as CBEs by regulatory bodies. Therefore, they are also not in general accepted by consumers.

There remains a need for a simplified process, without any modification by enzymatic reaction, to produce confectionery fat compositions, such as coating fats, in particular cocoa butter equivalents (CBEs), by using a fat preferably from a single natural source, instead of multiple fats in order to reduce the complexity and the cost of the process and to increase the efficiency of the use of the relevant fat source, such as, in particular, shea butter. There is also a need for comparable or even improved quality confectionery products, such as chocolates, using fat compositions that can be produced via a simplified and efficient process compared to conventional products. Meanwhile, there also remains a need to easily control and maintain the quality and the composition of such confectionery fat compositions by avoiding uncontrollable fluctuations in the quality of the raw fat sources.
It has been observed that for most of the attributes the results are overall comparable. However, Dark chocolate A, Dark chocolate B and Dark chocolate C by using the fat compositions produced by the simplified and efficient process according to the invention surprisingly have a desirable quick meltdown compared to Reference dark chocolate and Comparative dark chocolate (the evaluation results illustrated in a spider plot diagram -
According to the present invention, there is provided a process of preparing a fat composition comprising the steps of: a) providing a fat comprising at least 25% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; b) fractionating the fat source obtained in step a) to form a stearin fraction comprising at least 60% by weight of StOSt triglycerides based on the total glycerides present in the fat, wherein St is stearic acid and O is oleic acid; and c) blending the fat source obtained in step a) and the stearin fraction obtained in step b) in a weight ratio of from 90:10 to 10:90 to form a fat composition.
For instance, the process of the present invention may comprise the steps of a) providing a fat consisting of shea butter, b) fractionating the shea butter to form a stearin fraction comprising at least 60% by weight of StOSt triglycerides based on the total glycerides present in the fat and c) blending the shea butter with the stearin fraction obtained in step b) in a weight ratio of from 90:10 to 10:90 to form a fat composition.
The process of the invention has been found to be particularly useful for producing a fat composition suitable for confectionery applications from a single natural fat source without any complex process route involving multiple fat sources or any complex modification steps such as an enzymatic reaction. Accordingly, the process of the invention has been particularly simplified and the efficiency of the process can be significantly improved. Also, the process of the invention is suitable for maintaining the constant and reliable quality of the prepared fat composition with minimized influence of the quality of the raw fat material in comparison to merely using the unmodified natural fat source alone. Furthermore, the process also improves the use of the single natural fat source. In addition, it has been surprisingly found that the fat composition obtained by the improved process according to the invention can still enable producing an acceptable or even improved confectionery product, particularly in terms of texture and organoleptic properties.
The term “fat” refers to glyceride fats and oils containing fatty acid acyl groups and does not imply any particular melting point. The term “oil” or “butter” is used synonymously with “fat”.
The term “fatty acid” refers to straight chain saturated or unsaturated (including mono- and poly unsaturated) carboxylic acids having from 8 to 24 carbon atoms. A fatty acid having x carbon atoms and y double bonds may be denoted Cx:y. For example, palmitic acid may be denoted C16:0 and oleic acid may be denoted C18:1. The fatty acid profile may be determined by fatty acid methyl ester analysis (FAME) using gas chromatography according to ISO 12966-2 and ISO 12966-4. Thus, percentages of fatty acids in compositions (e.g. palmitic acid (C16:0), stearic acid (C18:0), oleic acid (C18:1) etc.) referred to herein include both acyl groups such as tri-, di- and mono- glycerides and free fatty acids (but exclude any unsaponifiable matter) and are based on the total weight of C8 to C24 fatty acid residues.
The term “triglyceride” refers to glycerides consisting of three fatty acid chains covalently bonded to a glycerol molecule. Amounts of triglycerides specified herein are percentages by weight based on total triglycerides present in the fat composition. The notation triglyceride XYZ denotes triglycerides having fatty acid acyl groups X, Y and Z at any of the 1-, 2- and 3-positions of the glyceride. The notation A2B includes both AAB and ABA, and AB2 includes both ABB and BAB. Triglyceride content may be determined for example by GC (ISO 23275).
The fat provided in part a) of the process of the invention is preferably from a natural fat source, more preferably a single natural fat source. The term “natural fat source” refers to a source of fat that is naturally occurring (e.g., from a single vegetable source such as shea) in contrast to synthetic fats. A fat from a natural fat source will not have undergone fractionation or reaction of the fat, such as interesterification, and is not blended with greater than 10 % by weight, of fats from other sources, preferably not blended with any other fats i.e., it preferably consists of the fat from the natural fat source. The fat obtained from a natural fat source may have been subjected to one or more refining steps well-known in the art, such as neutralization, bleaching and deodorization.
The term “fractionating” or “fractionation” refers to a process well known in the art for separating the liquid part (olein fraction) and the solid part (stearin fraction) based on different melting points or hardness. Typical fractionation processes include dry fractionation, solvent fractionation (also known as wet fractionation) and detergent fractionation.
In a preferred embodiment, the fat composition prepared according to the process of the invention is a confectionery fat composition, more preferably a coating fat composition and even more preferably a cocoa butter equivalent (CBE) fat composition.
The term “cocoa butter equivalent” refers to the vegetable fats other than cocoa butter that have physical properties and a molecular structure that are virtually identical to those of cocoa butter.

Tempering may, for example, be carried out by cooling the confectionery composition to 26-28° C. from a higher temperature, and then heating to 31-32° C. It has surprisingly been found that tempering a confectionery composition comprising a fat composition of the invention can be carried out more easily, with the formation of a greater number of seed crystals.

The listing or discussion of an apparently prior-published document in this specification should not necessarily be taken as an acknowledgement that the document is part of the state of the art or is common general knowledge.
Preferences and options for a given aspect, embodiment, feature or parameter of the invention should, unless the context indicates otherwise, be regarded as having been disclosed in combination with any and all preferences and options for all other aspects, embodiments, features and parameters of the invention.
The following non-limiting examples illustrate the invention and do not limit its scope in any way. In the examples and throughout this specification, all percentages, parts and ratios are by weight unless indicated otherwise.
Shea butter containing 41% by weight of StOSt is one-stage fractionated using acetone to obtain shea stearin fraction (hard fraction) and shea olein fraction (soft fraction). The content of StOSt in the shea stearin fraction is concentrated up to 71% by weight of StOSt.
In addition, hard palm mid fraction is obtained from palm oil by multiple-stage wet fractionation using acetone.
Fat composition A is prepared by blending 80% by weight of shea butter and 20% by weight of shea stearin. Fat composition B is prepared by blending 65% by weight of shea butter and 35% by weight of shea stearin. Fat composition C is prepared by blending 40% by weight of shea butter and 60% by weight of shea stearin.
Reference fat composition is prepared by blending 45% shea stearin and 55% hard palm mid fraction. In order to produce Reference fat composition, different fat sources (palm oil and shea butter) are required and multiple-stage complex processes need to be applied.
Comparative fat composition is prepared by blending 70% shea butter and 30% shea olein.
All the fat compositions are bleached and deodorized before used in the following applications.
The analytical results of Fat composition A, Fat composition B, Fat composition C, Reference fat composition and Comparative fat composition are shown in Table 1.
In the above table:
O, P, St, L and A refer to oleic, palmitic, stearic, linoleic and arachidic acids, respectively; Triglyceride compositions: e.g., POSt, and other triglycerides were determined by GC (ISO 23275), wherein each GC peak includes triglycerides having the same fatty acids in different positions e.g., POSt is in the same signal peak as PStO and StOP; and S26Nx refers to solid fat content determined by NMR on stabilized fat (stabilized at 26° C. for 40 hours) measured at x°C according to ISO 8292-1.
The chocolates were produced using the fat compositions prepared above. The chocolate recipes used are set out in the following tables: Table 2 and Table 3.
The chocolates were produced as well known in the art by using a roller refiner and a conche. The chocolates were tempered in the Leatherhead tempering kettle and moulded into bars. This means that the chocolates are cooled down until 26-28° C. and then heated until 31-32° C. The temper index was determined with a temper meter. The moulds were cooled in a static cooling cabinet with high wind speed. The contraction in the moulds was observed during the cooling cycle. The chocolates bars were made and used for different evaluations including hardness, sensory evaluation and storage test. The overview of the chocolate bars in relation to the fat composition used is listed in Table 4.
Regarding the dark chocolates, the tempering behaviors of Comparative dark chocolate are very similar to those of Reference dark chocolate. Dark chocolate A, Dark chocolate B and Dark chocolate C could be deposited at a higher temperature which indicates that more seeds have been formed during the tempering process. This indicates that the fats produced by the process according to the invention (Fat composition A, Fat composition B and Fat composition C) can be tempered more easily than Reference fat composition and Comparative fat composition.
Regarding the milk chocolates, Milk chocolate A shows similar tempering behaviors to Reference milk chocolate. For Milk chocolate B and Milk chocolate C, the depositing temperature was higher than that of Reference milk chocolate. This indicates that Milk chocolate B and Milk Chocolate C are particularly easy to temper. Milk chocolate C has a depositing temperature similar to that of Comparative milk chocolate.
It can be concluded that Fat composition B and Fat composition C produced by the process according to the invention are particularly preferred.
Hardness of the chocolate bars was measured using the Brookfield texture analyzer (needle TA9 and penetration depth of 2 mm at 0.5 mm/sec) after storing the samples at 20° C. for 2 days, 1 month and 3 months. Each sample was measured 5 times and the average results are shown in Table 5 and Table 6.
Based on the results, it can be concluded that the chocolates (either dark chocolate or milk chocolate) made from the fat compositions produced by the process according to the invention have the comparable hardness as the reference. This suggests that the desired texture of the chocolates is still surprisingly obtained by using the fat compositions produced by the simplified and efficient process according to the invention. In particular, the increase of the hardness in the chocolates made from the fat compositions produced by the process according to the invention is relatively limited, which indicates less pronounced post hardening and the desired prolonged shelf life in terms of texture.
An expert sensory panel (n=6) evaluated the chocolate samples after 1 month of storage at 18° C. The chocolate samples were evaluated against the chocolate containing only cocoa butter (which has score of 0 for all attributes) and scored them on the standard attributes in Table 6.
