[0105] Preferably, the barrier layer contains, calculated by weight of dry matter, at least 2 wt. % of protein selected from soy protein, egg protein, whey protein, legume protein, gluten and combinations thereof.

[0106] In one advantageous embodiment of the invention the barrier layer contains, calculated by weight of dry matter, 10-45 wt. %, more preferably 12-40 wt. % of heat setting protein selected from soy protein, egg protein, legume protein and combinations thereof. Even more the barrier layer contains, calculated by weight of dry matter, 10-45 wt. %, more preferably 12-40 wt. % of heat setting protein selected from soy protein, pea protein, lupin protein and combinations thereof. Most preferably, the barrier layer contains, calculated by weight of dry matter, 10-45 wt. %, more preferably 12-40 wt. % of soy protein.

[0107] The combination of the heat setting protein and the oligosaccharides preferably constitutes at least 35 wt. % of the dry matter of the barrier layer, more preferably at least 45 wt. % of the dry matter of the barrier layer and most preferably at least 50 wt. % of the dry matter of the barrier layer.

[0117] Preferably, the starch in the crumb particles is essentially completely gelatinized as demonstrated by the absence of birefringence that is associated with the presence of starch granules. Starch granules show birefringence or a typical “maltese cross” when viewed in polarised light. The property of birefringence is brought about because the starch molecules are radially oriented within the granule. When starch is heated in water, birefringence is lost.

[0118] The crumb particles employed in accordance with the present invention preferably have been obtained by a process that comprises extruding a mixture comprising flour and water, wherein the mixture of flour and water is heated to a temperature in excess of 90° C., more preferably in excess of 105° C. during extrusion.

[0121] The inventors have found that it may be advantageous to prepare an ovenable snack according to the present invention by alternatingly applying two or more barrier and crumb layers. Accordingly, in a preferred embodiment, the layer of crumb particles that is deposited on the barrier layer that surrounds the filling is coated with a second barrier layer and a second layer of crumb particles is deposited onto the second barrier layer.

[0122] Preferably, both the first and the second barrier layer are barrier layers as described herein before. Preferably, the dry composition of the second barrier layer is identical to the dry composition of the first barrier layer that surrounds the filling.

[0123] Likewise, the crumb that is employed in the second layer of crumb particles preferably is a crumb as described herein before.

[0124] According to another preferred embodiment, the layer of crumb particles on the outside of the ovenable snack is coated with oil. The application of an oil coating offers the advantage that after oven heating the ready-to-eat snack closely resembles a deep fried snack. Preferably, the oil contains at least 80 wt. % triglycerides.

[0125] In accordance with a particularly preferred embodiment, the ovenable snack of the present invention is packaged in a packaging material that carries instructions to heat the food product in an oven, preferably at a temperature in the range of 160-220° C.

[0126] Another aspect of the present invention relates to a process of manufacturing an ovenable pre-baked crumb-coated snack, said process comprising: [0127] (a) providing a portion of a filling composition having a water content of at least 30 wt. %; [0128] (b) coating the portion of filling composition with a layer of coating composition to produce a coated portion, said coating composition having a water content of at least 45 wt. % and containing: [0129] 15-75 wt. %, calculated by weight of dry matter, of oligosaccharides having a degree of polymerisation (DP) in the range of 4-20; [0130] 2-45 wt. %, calculated by weight of dry matter, of protein; [0131] 0-50 wt. %, calculated by weight of dry matter, of starch; [0132] wherein the combination of the oligosaccharides, protein and starch constitutes at least 50 wt. % of the dry matter of the coating composition; [0133] (c) applying crumb particles onto the coated portion to produce a crumb-coated portion; [0134] (d) pre-baking the crumb-coated portion to produce a pre-baked portion; and [0135] (e) packaging the pre-baked portion.

[0136] Preferably, step (d) of the aforementioned manufacturing process yields an ovenable pre-baked crumb-coated snack as described herein before.

[0138] The dry composition of the coating composition employed in the process preferably is identical to that of the barrier coating layer as described herein before. The ingredients of the coating composition that is applied in the present process are also preferably as described herein before.

[0139] The coating composition preferably has a water content of 48-88 wt. %, more preferably a water content of 50-87 wt. % and most preferably a water content of 52-86 wt. %.

[0140] Before coating the portion of filling composition with uncooked coating composition, the portion may suitably be coated with predust. The application of predust facilitates the adhesion of the coating composition onto the surface of meat, fish, poultry and vegetables.

[0141] According to a particularly preferred embodiment, the crumb particles employed in the present process have a water content of less than 8 wt. %, more preferably of less than 7 wt. % and most preferably of less than 6 wt. %. Typically, the crumb particles have a water content of at least 1 wt. %.

[0142] The crumb particles employed in the present process preferably have a glass transition temperature of more than 60° C., more preferably of more than 80° C., even more preferably of more than 100° C. and most preferably of more than 110° C.

[0143] The glass transition temperature of the crumb particles can be determined by modulated DSC using the following procedure: [0144] A ground sample of 20-30 mg is added to a stainless steel DSC pan. The DSC pan is inserted in the DSC equipment. [0145] The sample is equilibrated at 20° C., and then heated at a rate of 2° C./min to a maximum temperature of 160° C. [0146] The sample is cooled back to 20° C., and then heated again at a rate of 2° C./min to a maximum temperature of 160° C. [0147] The heat flow is measured during the heating cycle, glass transition is determined in the second heating cycle.

[0148] In the present manufacturing process preferably 100 parts by weight of filling composition are combined with 3 to 60 parts by weight of coating composition, and 3 to 60 parts by weight of crumb particles. More preferably, about 100 parts by weight of filling composition are combined with 5 to 45 parts by weight of coating composition, and 5 to 50 parts by weight of crumb particles.

[0149] According to a particularly preferred embodiment, the crumb-coated portion is pre-baked prior to packaging. Typically, the crumb-coated portion is pre-baked in an oven at an oven temperature in the range of 130-280-° C. for 1-30 minutes, more preferably at an oven temperature in the range of 140-260-° C. for 2-20 minutes.

[0150] The core temperature of the crumb-coated portion preferably reaches a temperature of at least 50° C., more preferably of at least 55° C. and most preferably of at least 58° C. during pre-baking.

[0151] According to another preferred embodiment, the crumb-coated portion is coated with oil prior to pre-baking and/or the pre-baked portion is coated with oil prior to packaging. Preferably, the oil used for coating the portions contains at least 80 wt. % triglycerides. The oil preferably has a melting point of less than 30° C. The amount of oil that is applied preferably is in the range of 10 to 50% by weight of the crumb particles, more preferably in the range of 15 to 35% by weight of the crumb particles.

[0152] According to a particularly preferred embodiment, the process comprises freezing the pre-baked portion to a core temperature of less than −12° C. before it is packaged.

[0153] In order to minimize unwanted water migration, the pre-baked portion is introduced into a freezer within 5 minutes, preferably within 2 minutes after the pre-baking step has ended.

[0154] The pre-baked portion is preferably packaged after freezing.

[0155] Yet another aspect of the invention relates to a method of preparing a ready-to-eat snack, said method comprising heating the ovenable snack of the present invention in an oven to a core temperature of at least 60° C.

[0156] The invention is further illustrated by the following non-limiting examples.

EXAMPLES

Example 1

[0157] Ovenable pre-baked crumb-coated snacks, known in the Netherlands as “bitterballen”, were prepared as described below.

[0158] A ragout filling was prepared on the basis of the recipe that is shown in Table 1. The composition was cooked for 30 minutes at 95° C. and cooled over night at 4° C.

[0159] Coating compositions were prepared by combining glucose syrup, soy flour and water. The weight ratios in which glucose syrup and soy flour were applied in the different coating compositions are shown in Table 2. Also shown is the amount of water that was used to prepare the initial mix from 100 grams of dry ingredient(s).

[0160] The coating compositions were prepared by mixing 100 grams of dry ingredients with 100 to 514 ml water for 5 minutes at full speed using a K-beater. Next viscosity was measured using a Brookfield viscometer (spindle 62, 10 rpm) and water was added to reduce viscosity to less than 1000 mPa.Math.s.

[0161] The ragout filling was extruded and shaped by a Rheon into balls of 17 grams. These were kept frozen until usage. At usage the ragout balls were fully thawed by keeping them over night at 4° C.

[0162] A predust (appr. 2.4% pick-up by filling portions) was applied. The composition of the predust is shown in Table 3.

TABLE-US-00003 TABLE 3 Ingredients Wt. % Crumbs (predust fraction of 59.0 extrusion-baked crumb) Oxidized wheat starch 40.0 Rapeseed oil 1.0

[0163] The predusted filling portions were coated with the coating composition (appr. 10% pick-up).

[0164] The coated portions were breaded with fine crumb (0.8-1.5 mm, appr. 7% pick-up). Thereafter these breaded portions were coated again with the coating composition (1.5-2.5 mm, appr. 16% pick-up). These coated portions were breaded with coarse crumb (appr. 8.% pick-up).

[0165] The crumb-coated portions were sprayed with oil (appr. 4% pick-up).

[0166] The crumb-coated portions so obtained were baked for 6 minutes in a preheated oven at 200° C. and 30% RH.

[0167] After the oven, the pre-baked snacks were placed into a shock freezer and kept at −34° C. for 30 minutes. Next, the frozen snacks were packaged in bags and stored in a freezer at −25° C.

[0168] After 2 days of frozen storage, the frozen snacks were prepared for consumption by baking them for approximately 14 minutes in an oven that had been preheated to 180° C. The snacks were taken from the oven as soon as a core temperature of 72° C. had been reached.

[0169] Pictures were taken of the snacks immediately after they had been removed from the oven. These pictures were used to score the amount of cracks that had been formed during bake-off.

[0170] Two minutes after removal from the oven, the snacks were evaluated by an expert panel. The panel scored the quality of the snacks, paying special attention to the appearance and the quality of the outer coating (crispiness etc.).

[0171] Both the amount of cracks and the organoleptic quality of the snacks were rated on a scale of 0 to 5: [0172] 0=unacceptable [0173] 1=bad [0174] 2=poor [0175] 3=good [0176] 4=very good [0177] 5=perfect

[0178] The results of the evaluations are summarised in Table 4.

[0184] Example 1 was repeated, except that this time an aqueous coating composition as disclosed in Example 8 of US 2016/0164930 was used as a coating composition (Coating Composition A) and compared to a coating composition according to the present invention (Coating Composition 1).

[0185] The recipes of these coating compositions are shown in Tables 9a and 9b.

[0186] Frozen pre-baked snacks were prepared as in Example 1 (Snack A using Coating Composition A, Snack 1 using Coating Composition 1).

[0187] After 3 days of frozen storage, the frozen pre-baked snacks were prepared for consumption by baking them for approximately 17 minutes in an oven that had been preheated to 220° C. The snacks were taken from the oven as soon as a core temperature of 72° C. had been reached.

[0188] Pictures were taken of the snacks immediately after they had been removed from the oven. These pictures were used to score the amount of cracks that had been formed during bake-off.

[0189] Two minutes after removal from the oven, the snacks were evaluated by an expert panel. The panel scored the quality of the snacks, paying special attention to the appearance and the quality of the outer coating (crispiness etc.). The percentage cracks was determined for a set of 10 baked snacks. Appearance, hardness and crispiness were scored on a scale of 0-5 (0=unacceptable and 5=perfect).

[0190] The results of the evaluations are summarised in Table 10.

TABLE-US-00011 TABLE 10 % Appearance Hardness Crispiness cracks (0-5) (0-5) (0-5) Snack A 100 1.0 1.0 2.0 Snack 1 0 5.0 4.5 4.5
