example 1

[0060] The corn-based cereal is cooked at a temperature of 150°C and a creamy filling comprising vegetable oil (which is completely liquid at 20°C), cocoa powder, sugar, starch and vanilla flavoring is fed into the cooking extruder. Round super puffed sticks were coextruded and traveled on a conveyor belt at a speed of 80 m / min. The strips were cut and passed through a tube of length 10 cm.

[0061] image 3 and Figure 4 The obtained segments are shown. In this particular example, the segment (12) has a diameter of 18 mm and a length of 35 mm. The filler accounts for 60% of the whole product, and the diameter of the filler is 6.5mm. This product has a density of 75 g / l.

[0062] The product was then dried to a moisture content of 2.5% and coated. This product is stored and sent to the packaging process step.

example 2

[0064] The yield point of the filler samples of Example 1 was measured using the equipment TextureAnalyser HDplus from Stable Micro Systems (Godalming, Surrey, UK) equipped with a 250 kg load cell and extrusion assembly. The extrusion assembly consisted of a cylindrical plastic barrel with an inner diameter of 48 mm and an inner depth of 103 mm, with a circular countersunk orifice, ie, a mold, at the bottom of the barrel with an inner diameter of 14 mm and an outer diameter of 10 mm. The orifice has a depth of 4 mm. The filling is sent to this barrel and the filled barrel is placed in the oven at 80°C for 20 minutes. At the end of this time, the bucket is quickly placed in the testing machine and the filler is forced through the die by the movement of the punch down into the bucket. The punch featured at its point of contact with the filler a transverse disc with a thickness of 5 mm and a diameter of 40 mm. The motion rate employed was 10 mm / s.

Abstract

The present invention concerns a co-extruded product (12) comprising a filling (21) and an outside open or closed cereal and / or starch based shell (20), wherein the amount of filling is comprised between 10 and 80 % in weight, the density of the product in the case of an open shell is comprised between 40 and 400 g / 1 and the density of the product in the case of a closed shell is comprised between 40 and 190 g / 1. The density of the product in the case of the open shell is preferably comprised between 40 and 190 g / 1.

Description

technical field [0001] The invention relates to a coextruded product comprising a filler and a shell. More particularly, the present invention relates to a coextruded product comprising a filler and an outer grain and / or starch based shell. Background technique [0002] Such products are known. In Extrusion Cooking, Technologies and Applications (ed. Robin Guy, Woodhead Press, 2001, pp. 178-179) a co-extrusion of a tubular puffed cereal biscuit with soft filling is described. Coextruded products with liquid or pasty fillers are also known. However, in order to avoid the filler flowing out of the shell during the cutting phase or during subsequent handling, the corresponding strip needs to be cooled at the outlet of the die according to the state of the art, or needs to be rolled up to incorporate more liquid filler to be filled The short length of the extrudates restricts the filler so that it does not leak out. In "Extrusion Cooking, Technologies and Applications" it is...
