Definitions

• the invention relates to an all natural ice-cream comprising non-fat milk solids and/or whey components, water, carbohydrates and fat.
• an all natural ice-cream is to be understood as an ice-cream which does not contain additives or components having an E-number and which does not contain egg yolk.
• the additives which are referred to by E- numbers can be found in European Parliament and Council Directive no. 94/36/EC, Official Journal of European Community no. L 237/13, 10 September 1994 (for colors), European Parliament and Council Directive no. 94/35/EC, Official Journal of European Community no. L 237/3, 10 September 1994 (for sweeteners), and European Parliament and Council Directive no. 95/2/EC, Official Journal of European Community no. L 61/1, 18 March 1995 (for other additives) .
• Food products may contain chemically modified natural products or synthetic products, i.e.
• the European patent application 574.907 discloses an ice-cream which does not contain such chemically modified natural products or synthetic products.
• the ice-cream is prepared from a cream obtained from milk products, water, other fat containing products and stabilizing agents wherein said stabilizing agents are a mixture of egg yolk, protein enriched milk products and vegetable fibers. These stabilizing agents are in particular free from synthetic components .
• the ice-cream according to the European patent application 574.907 does not satisfy all requirements with respect to mouth feel, texture, taste and storage stability. Parameters which influence these partly mutual dependent properties to a large extent are for example melt characteristics, overrun, extrusion characteristics and shape retention.
• the only property disclosed by the European patent application 574.907 is the overrun, i.e. the amount of air incorporated in the ice-cream as a percentage of the volume of the unfrozen ice-cream, which would be about 50 %.
• the melt characteristics of an ice-cream are in particular relevant to the mouthfeel upon consumption and to the storage stability and shape retention, respectively. Icecream may not melt away to quickly as this adversely effects storage stability and shape retention. On the other hand, the ice-cream should melt at a sufficient rate when it is exposed to elevated temperatures as otherwise it would not be ice- cream but a mousse-like product. Additionally, the overrun of an ice-cream may not be too high as otherwise the microstructure of the ice-cream is to weak leading to a too rapid disintegration of the microstructure and, consequently, to a too high melting rate of the ice-cream. Preferred quantitative indications for these properties will be presented below.
• Food products such as ice-cream and yoghurt desserts which are free from chemically modified products or synthetic products are also known from WO 92/11769.
• This reference relates to frozen dairy dessert compositions containing milk protein derived from e.g. skimmed milk and non-fat dry milk powder, a sweetening agent such as sucrose, fructose and aspartame, partially hydrolysed starch such as enzymatically hydrolysed starch and water.
• milk protein derived from e.g. skimmed milk and non-fat dry milk powder
• a sweetening agent such as sucrose, fructose and aspartame
• partially hydrolysed starch such as enzymatically hydrolysed starch and water.
• dessert products having an overrun of about 10 to 120 % it is preferred that if provided as a bulk-packaged dessert that the overrun does not exceed a value of about 60 % in order to be able to provide dessert products having the qualities of a high quality aerated frozen ice-cream. If provided in the form of e.g. a bar the overrun is preferably not higher than 35 % and more preferably not higher than 15 %.
• the European patent application 187.438 discloses a fruit juice mix for whipped and/or frozen applications which essentially contains all natural ingredients.
• the fruit juice mix comprises at least one type of fruit juice, a stabilizer derived from a natural source, soy bean protein and an amount of remaining ingredients such as water.
• the object of the present invention is to overcome the disadvantages mentioned above.
• the primary object of the invention is to provide an all natural ice cream free of chemically modified natural products or synthetic products, i.e. products having an E-number, which has an excellent taste and texture.
• Another object of the invention is to provide an all natural ice cream having excellent melt characteristics, good shape retention and a high overrun.
• the invention relates therefore to an all natural ice cream comprising not-fat milk solids and/or whey components, water, carbohydrates and fat, said ice-cream further comprising at least a stabilizing composition comprising (a) a taste improving substance, (b) a natural polysaccharide- based water phase thickening agent and/or (c) a natural polysaccharide-based air phase stabilizing agent.
• the natural polysaccharide-based agents (b) and (c) are based on modified natural polysaccharides, wherein the modification is by acid-, alkaline-, enzymatic-, and/or fermentative treatment.
• the all natural ice-cream comprises at least the combinations (a) and
• the taste improving substance (a) may be derived from chemically modified, fermented, non-chemically and/or an enzymatically treated natural fat source.
• Substance (a) improves the taste of the all natural ice-cream and in particular the creaminess and structure stability.
• substance (a) is preferably an enzymatically treated natural fat source such as butter or cream or a derivative thereof, enzymatically treated citric oil, cacao butter, oils derived from nuts like almons and pistachio, etcetera.
• the water phase thickening agent (b) is preferably selected from extracts from fruit and/or vegetables and other extracts.
• Suitable extracts are those which contain one or more natural charged polysaccharides, natural linear polysaccharides and natural linear charged polysaccharides. Suitable examples of such polysaccharides include extracts from citrus, apple, sugar beet, sea weed, cereals and mixtures thereof.
• the air phase stabilizing agent (c) is preferably selected from cellulose-like components. Suitable celluloselike components are natural linear neutral polysaccharides. According to the invention component (c) is preferably selected from sources as chicory and artichokes and vegetable sources such as grinded wood pulp, cotton fiber and cereal fiber extracts or mixtures thereof.
• the all natural ice-cream may contain 0.05 to 5 % wt. of the stabilizing composition, but it is preferred that the ice-cream contains 0.2 to 2.0 % wt. of said composition and in particular 0.5 to 1.7 % wt.
• the stabilizing composition comprises preferably at least 0.05 to 1.0 % wt. of (a), 0.1 to 1.0 % wt . of (b) and 0.5 to 2.0 % wt. of (c) .
• the stabilizing composition comprises more preferably at least 0.1 to 0.5 % wt. of (a), 0.2 to 0.8 % wt. of (b) and 0.7 to 1.5 % wt. of (c) .
• the all natural ice-cream according to the invention is characterised as having an overrun of at least 60 % and a mix viscosity of at least 20 Pas.
• the all natural ice-cream according to the invention is further characterised by a melting rate profile such that after 100 min. no more than 40 vol.%, preferably no more than 30 vol.% and in particular no more than 25 vol.%, and after 200 min. no more than 80 vol.%, preferably no more than 70 vol.% and in particular no more than 60 vol.% of the all natural ice-cream has melted.
