A snack filled with fruit pieces

Abstract: A snack filled with fruit pieces is described in which the fresh fruit equivalent of the fruit weighs around twice as much as the pastry. A method for producing this snack is also described which relies essentially on a filling technique: the fruit pieces are introduced before baking, a fruit jam is introduced after baking.

Description: The present invention relates, in its more general aspect, to a filled baked product which, in the description which follows and in the subsequent Claims, will be referred to as a filled snack, a term widely used for this type of baked product in the industry. The invention relates more specifically to a snack which comprises a pastry exterior and a fruit inside (or filling), in which the fruit is in pieces, as well as to a method for the mass production of such a snack. It is known that of all the filled snacks that make up this busy sector of the food industry, there is not one available today which can really claim that its filling is constituted by fruit pieces since the only "fruit" fillings used and usable until now are essentially constituted by jam with some (few) small pieces of fruit dispersed in it. It is also known that this limitation, with which manufacturers are very unhappy, is almost totally due to technical and technological reasons involving equipment and the problems of filling and baking the snacks. In addition, quite apart from the lack of fruit pieces in currently available jam-based fillings, such jam products necessarily have a high sugar content which is unwelcome from a dietary and nutritional point of view. GB-A- 691435 relates to cereal products containing fruit and to a method for preparing the same. EP-A- 0384238 decribes a method of preparing a long-life fruit based stuffing for pastry products. There is therefore a need for a snack of the type described in which, from an organoleptic point of view, fruit pieces constitute the characterising component of the product, this being a snack which can be mass produced. In order to satisfy this need, the present invention provides a snack comprising a pastry casing and a fruit filling, characterised in that the filling comprises, in percentages by weight of the weight of the snack: from 11 to 35% of fruit pieces, dehydrated to a moisture content of between 25 and 30% and having a water activity (Aw) value of between 0.75 and 0.85, and from 6 to 20% of fruit jam as the fluid component of the filling. As to the type of fruit and jam which may be used for the filling of the snack of the invention, there is no limit in practice. From an organoleptic point of view, particular advantages are provided by the use of fruit cocktails. To advantage, the pastry casing of the snack of the invention has a consistency which is just sufficient to provide containment and support for its filling of fruit pieces, and an Aw value and moisture content isotonic with those of the filling, so as to prevent any pastry/fruit exchange of moisture either during the preparation of the snack or during the shelf-life of the product, which could damage the quality of the product. According to a further characteristic of this invention, the pastry casing is constituted by a sheet of leavened dough commonly known as Danish pastry. In addition the ratio of the weight of the Danish pastry casing to that of the filling of the snack of the invention is, to advantage, between 60/40 and 40/60. The present invention provides a method for the production of a snack with a filling of pieces of fruit, characterised in that it includes the successive steps of: preparing a casing of uncooked dough; filling the casing with a first filling of fruit pieces having a moisture content of from 27 to 38% and an Aw of between 0.76 and 0.88; the fruit constituting from 11 to 35% by weight of the weight of the snack; proving and baking; cooling; adding a second filling comprising a quantity of fruit jam constituting from 6 to 20% by weight of the weight of the snack. The fundamental teaching of the method of the present invention for producing snacks with a filling which includes fruit pieces is that filling is carried out in two separate steps: a first step (or pre-baking step) in which only the fruit pieces are put inside the dough before baking, a second step (or post-baking step) in which the fluid portion (fruit jam) of the filling is put into the baked, cooled product. A second teaching is to use fruit pieces dehydrated to a predetermined moisture content and Aw value such as to enable them to undergo the various processes required by mass production without losing their organoleptic characteristics or nutritional value. An additional teaching is to carry out the second, or post-baking, filling step with a jam (the fluid component of the filling) which has the dual task of: reviving the fruit which will have shrunk slightly during baking, that is, restoring it to its original appearance, consistency and chewability; filling the space left inside the snack by the "shrinking" of the fruit during its passage through the oven. In accordance with one characteristic of the invention, the aforesaid first, pre-baking filling step is carried out by arranging a predetermined quantity of fruit pieces on a portion of a sheet of uncooked Danish pastry dough having dimensions corresponding to the snack which is to be produced and subsequently folding over the opposite sides of the portion so as to wrap the fruit arranged thereon. During this step, the use of a "binding" fluid is very useful to hold the fruit pieces on the respective portion of the sheet of pastry dough, this binder being glucose syrup for example and for preference. Before baking, the following steps are carried out: forming; that is folding the pastry strip over so as to enclose the fruit pieces and sealing the turnover obtained transversely, and proving under entirely conventional conditions of temperature and humidity for a conventional period of time. The baking conditions are also entirely conventional. Characteristics and advantages provided by the invention will become clearer from the description which follows of one example of the production of filled snacks according to the invention. A plurality of continuous strips of uncooked Danish pastry dough are fed on an appropriate conveyor belt, advanced stepwise, to a first filling station. Each strip (average thickness around 4-5mm, width 13-14 cm) is already marked with two longitudinal fold lines which extend parallel to the edges of the strip and define borders having a width of about 2 cm. A cocktail of pieces of fruit, already treated with a small, predetermined quantity of sugar syrup as a binding agent, arrives at the same station on a separate conveyor in an intermittent flow. The fruit pieces have been dehydrated earlier so as to have an average moisture content of 35% with an Aw value of 0.85. At each advance of the strips of Danish pastry dough through the filling station, a predetermined measure of the cocktail of fruit pieces is deposited on the central part of each portion thereof. The measures (the same for all the strips of dough) may vary between 8 and 12g and are preferably 9-10 g when the overall weight of the finished snack is to be 36-38 g. The measures of fruit may naturally vary within much broader limits than those given above by way of example, provided that the dimensions, consistency and weight of the strips of dough which will form the casing for the fruit are adjusted at the same time. Downstream of the filling station, each strip of dough, with the respective measures of fruit arranged on it, passes through a forming station where the side borders are folded over the fruit pieces so as to cover them completely, thereby obtaining a tubular body of dough filled with successive, spaced measures of fruit pieces. In this same forming station, each of these continuous tubular bodies is cut between each measure of fruit and the next to form portions of predetermined length. As this operation is carried out on uncooked dough, it also simultaneously seals each portion transversely, providing a semifinished product which is closed around its periphery and is filled with fruit ready for proving and baking. In such a semifinished product, the dough/fruit ratio is 70/30, though this value may of course vary widely (50/50-80/20) according to the desired organoleptic characteristics of the finished snack. Proving takes place in an environment where the temperature is around 30°C with a relative humidity of around 85% and the semifinished products remain there for around 8 hours. The risen semifinished products are baked at a temperature of around 180-210°C for 13-15 minutes. On leaving the oven, the baked products are cooled to around 50°C and sent to a second filling station (post-baking filling) where they are injected with a predetermined measure, of around 6g, of fruit jam. This is preferably an orange jam with pieces of apple. Here again, the quantity of jam may vary within broad limits depending on the product to be made, bearing in mind that the jam has the dual task of reviving the fruit which has shrunk during baking and of completely filling the cavity inside the snack. It is important to underline the great advantage provided by the present invention. The total weight of the finished snack is 36-38g; the weight of the fruit pieces (with a moisture content of 30-35%) is 9-10g; that of the jam is around 6g. Therefore the weight of the pastry in the finished snack is 22-25g. Bearing in mind that 9-10g of fruit with a moisture content of 30-35% is equivalent to 45-50g of fresh fruit, it is clear that the present invention provides a fruit snack in which the fruit is equivalent to fresh fruit WEIGHING OVER TWICE AS MUCH AS THE PASTRY.
