Abstract

A beverage composition comprises fat, protein, thickener and water, wherein the fat comprises at least 40% by weight of conjugated linoleic acid or a derivative thereof (CLA).

Description

BEVERAGE COMPOSITION COMPRISING CLA
This invention relates to a beverage composition and to a method for its production.
The nutritional value of the diet has come under increasing scrutiny. Food supplements are often taken by individuals in order to obtain nutritional benefits. However, food supplements are typically in the form of capsules or the like and have the disadvantage that they are inconvenient in that individual has to remember to take them. Food supplements of this type are typically not flavoured and are not attractive to many consumers.
Nutritional supplements have been incorporated into food products but the resulting food products can have an undesirable taste and the incorporation of the supplement can have a deleterious effect on the stability of the products.
Conjugated linoleic acid (CLA) is a conjugated dienoic fatty acid having 18 carbon atoms. As a result of the presence of the two double bonds in CLA, geometrical isomerism is possible and the CLA molecule or moiety may exist in a number of isomeric forms. The cis9, transl l ("c9tl l") and translO, cisl2 ("tlθcl2") isomers of CLA are generally the most abundant and beneficial pharmacological effects have been identified for each of these isomers.
US 6,468,556 discloses the administration of CLA for inhibiting liver fat accumulation. However, this document is not concerned with the stability of its formulations or whether they have an acceptable taste and texture.
US 2007/0031536 relates to fermented foods that comprise CLA in the form of a glyceride.
US 2005/0013907 describes food compositions derived from milk comprising CLA glycerides. The compositions contain significant amounts of added sugar. US 2006/0057817 discloses emulsions containing unsaturated fatty acids and their esters. The emulsions may be used in foods, including beverages.
JP-A-2000 050841 relates to a powder containing CLA. The powder can be used in foods and drinks and is prepared by mixing the CLA with gum arabic to form an oil-in-water emulsion, followed by drying and pulverising.
There remains a need for beverage compositions containing CLA that can have a low energy content (i.e., are low calorie) but still have good organoleptic properties such as taste and mouthfeel. We have now found beverage compositions that solve these problems.
Accordingly, the present invention provides, in a first aspect, a beverage composition comprising fat, protein, thickener and water, wherein the fat comprises at least 40% by weight of conjugated linoleic acid or a derivative thereof (CLA).
hi a second aspect, the invention provides a beverage composition comprising fat, protein and water, wherein the fat comprises at least 40% by weight of conjugated linoleic acid or a derivative thereof (CLA), wherein the composition has an energy content of less than 100 kcal /10Og, preferably less than 80 kcal/100g, most preferably 55 to 75kcal/100g.
A third aspect of the invention is a beverage composition comprising fat, protein and water, wherein the fat comprises at least 40% by weight of conjugated linoleic acid or a derivative thereof (CLA), wherein the composition comprises less than 8% by weight of added sugar.

The fat in the beverage composition of the invention comprises at least 40% by weight of the fat phase of conjugated linoleic acid (CLA) or a derivative thereof. Preferably, at least 50% by weight, for example at least 60%, at least 70%, at least 80% or at least 90% by weight of the fat phase is conjugated linoleic acid (CLA) or a derivative thereof. The upper limit of CLA in the fat phase may be 95% or 100% by weight. The amount of CLA in the fat is based on the total weight of fatty acids in the fat (calculated as free fatty acid). The term "CLA", as used herein refers to conjugated linoleic acid and its derivatives. The CLA may be used in the form of the free acid. Derivatives of conjugated fatty acids include salts and esters thereof, or a mixture of two or more of these materials. Salts are non-toxic, pharmaceutically acceptable and/or acceptable for use in food products and/or pharmaceuticals and include, for example, salts with alkali metals and alkaline earth metals such as sodium, calcium and magnesium, preferably sodium. Esters include, for example, mono-, di- and tri- glycerides and mixtures thereof, and Ci to C6 alkyl esters (where the alkyl group can be straight chain or branched), as well as esters formed with alcohols that are acceptable in food products or pharmaceutical products, such as are disclosed in EP-A-1167340, the contents of which are incorporated by reference herein. Suitable alcohols include terpene alcohols or sesquiterpene alcohols, for example menthol, isopulegol, menthenol, carveol, carvomenthenol, carvomenthol, isobornylalcohol, caryophyllenealcohol, geraniol, farnesol and citronellol.
The preferred form of CLA for use in the invention is as a glyceride. Particularly preferred are diglycerides and triglycerides, with triglycerides being even more preferred.
The CLA may comprise one isomer or a mixture of two or more different isomers including: cis, cis; cis, trans; trans, cis; and trans, trans isomers. Preferred isomers are the translO, cisl2 and cis9, trans 11 isomers (also referred to herein as tlθcl2 and c9tl l, respectively), including these isomers in relatively pure form, as well as mixtures with each other and/or mixtures with other isomers. More preferably, the conjugated linoleic acid or derivative thereof comprises trans 10, cisl2 and cis9, trans 11 isomers and the weight ratio of trans 10, cisl2 isomer to cis9, trans 1 1 isomer or vice versa is at least 1.2:1, such as 1.3: 1, even more preferably at least 1.5:1, e.g., in the range 1.5:1 to 100:1 or 1.5:1 to 10:1, such as a 60:40 or 80:20 mixture of the translO, cisl2: cis9, transl l isomers. Particularly preferred are compositions comprising the trans 10, cis 12 isomer or the cis9, trans 1 1 isomer as the major isomer component i.e., present in an amount of at least 55 %, preferably at least 60 %, more preferably at least 70 %, even more preferably at least 75 %, most preferably at least 80 %, such as at least 90 % or even 100 % by weight based on the total amount of conjugated linoleic acid. For example, the CLA may comprise c9tl 1 and tlθcl2 isomers and the weight ratio of the c9tl l to tlθcl2 isomers may be from 99:1 to 1 to 99, preferably from 90:10 to 10:90 most preferably from 80:20 to 20:80.
CLA can be produced in conventional ways. For example, CLA can be produced by known methods, such as that described in EP-A-902082, the contents of which are incorporated herein by reference. CLA products that are enriched in one or more isomers are disclosed in WO 97/18320, the contents of which are also incorporated herein by reference.
Examples of other fatty acids that may be present in the fat include linoleic acid, oleic acid, taxoleic, juniperonic, sciadonic, saturated fatty acids, pinolenic acid and EPA (eicosapentaenoic) and DHA (docosahexaenoic). These other fatty acids may be present as free acids or derivatives in the same way as CLA and are preferably present as glycerides, more preferably triglycerides.
The CLA is optionally blended with additional fatty acids or glycerides before being used in the fat of the present invention. When the compositions contain one or more fatty acids and/or glycerides in addition to the CLA, the additional fatty acid(s) and/or glycerides are preferably selected from liquid oils, such as soybean oil, sunflower oil, rape seed oil and cotton seed oil; cocoa butter and cocoa butter equivalents; palm oil and fractions thereof; enzymically made fats; pine nut oil; fish oils and fractions thereof; conjugated linoleic acid and enriched isomer mixtures; gamma linolenic acid and enriched mixtures thereof; hardened liquid oils; and mixtures thereof.
The beverage compositions of the invention may have one or more of: improved taste; more refreshing taste; stability in that there is little phase separation; no problems with aggregation and /or flocculation of particulate matter; no creaming; optimal cloudiness (some drinks should be cloudy, whilst others should not); good homogeneity; enhanced viscosity; good colour; a good level of sweetness; balanced flavour; a light feeling in the mouth; little or no aftertaste; and an optimal droplet size distribution. Many or all of these positive effects preferably persist over time e.g., all of the effects remain positive over a period of at least 3 months, preferably about 6 to 12 months. Surprisingly, these positive attributes can be achieved in beverages having relatively low energy contents. This means that it is possible to produce a low calorie product, particularly in a fruit-based beverage, comprising CLA.
The CLA can be included in the beverage of the invention as an oil or in the form of a powder, such as a free flowing powder. CLA and its derivatives in powder form can be produced, for example, by spray drying CLA, or a fat comprising CLA, with protein and/or carbohydrate, with the powder typically comprising from 50 to 90% by weight of fat. A preferred powder comprises 70 to 90% by weight triglyceride of which at least 70% by weight is CLA. It has been found that use of the powder can give extra stability to the beverage.

A solution of a 4% pectin in hot water of >90°C was prepared. Whey protein powder was dispersed in the rest of water, heated to 400C and hydrated for at least 15 minutes.
A 25% pre-emulsion of the oil in yogurt was made. The yoghurt was heated to 60 0C and slowly the oil was mixed-in. The mixture was homogenized dual-stage 200/50 bar and cooled to 4°C till further use. Sugar, sweetener (10Ox solution in water), pectin solution, whey protein solution and pre-emulsion were added to this mixture. Sodium citrate / citric acid till pH=4 +/- 0.1 was added. The mixture was pre-heated to 40°C, homogenized dual-stage 200/50 bar, and filled in bottles.
For each of the oils the following experimental set up was prepared:
9 samples containing 400 ml yoghurt drink were prepared. 4 samples were stored at 70C and 4 bottles at 25°C. One sample of 400 ml yoghurt was directly processed by extracting the oil with the methanol/ chloroform extraction method (starting sample). After 2, 4, 7 and 10 days of storage, the oil was extracted from each sample with the methanol/ chloroform extraction method.
The extracted oils were tested for rancimat analysis.
As comparison all oils were stored and extracted the same way as described above:
Separate samples of clarinol and safflower oil were prepared and stored at 7°C and at 25°C, respectively. After 2, 4, 7 and 10 days from each storage, the oil was extracted with the methanol/ chloroform extraction procedure.
Fat extraction procedure for yoghurt drinks:
All yoghurt drink mixtures were extracted in 4 portions; this is due to the workability of the samples together with the solvents which are needed to conduct the extractions. To about 100 g of yoghurt mixture about 10 g of KCl, 100 ml chloroform and 50 ml methanol were added. The samples were put on a turax for 3 minutes with a speed of about 12000 rpm. The mixture was divided in 2x100 g bottles. This procedure was repeated 4 times until 8x100 g bottles were received. The bottles were centrifuged for 5 minutes at 4500 rpm. The upper layer of each bottle was removed with a pipette. The lower layer together with the white pellet which was received after centrifugation was put over a filter. The filtrate was put in an empty flask on the rotor vapour equipment. The temperature of the water bath was set at 35 0C and the pressure slowly brought down to about 20 mbar. Nitrogen was bubbled through the sample overnight.
Results
Temperature 4-7 0C Rancimat (AOCS Cd 12b-92)

YD = yoghurt drink
A higher rancimat value indicates a greater stability of the oil. Therefore, the results show that the CLA is surprisingly more stable in the drink than safflower oil, even though both oils have comparable stability when not formulated.
