Liquid-filled confectionery compositions
A liquid-filled confectionery composition ( 10 ), comprising a liquid-containing core ( 11, 12 ), an outer layer of confectionery coating ( 14, 15 ), and an intermediate protective layer ( 13 ) between the core ( 11, 12 ) and outer layer ( 14, 15 ). The liquid-containing core consists of a liquid ( 11 ) contained within a water soluble or biodegradable matrix ( 12 ). The edible water impermeable intermediate layer ( 13 ) is applied in alcohol and prevents the movement of water between the core ( 11, 12 ) and the outer layer ( 14, 15 ), thereby preventing the core ( 11, 12 ) from drying out.
1 . A liquid-filled confectionery composition comprising:
(a) a core, wherein the core contains a liquid;
(b) an outer coating or shell which encapsulates said core; and
(c) an intermediate layer disposed between said core and said outer coating; wherein said core comprises a liquid encapsulated within a water soluble or biodegradable matrix layer and said intermediate layer minimises liquid migrating out of said core.
2 . A composition according to claim 1 , wherein said intermediate layer prevents liquid migrating out of said core.
3 . A composition according to claim 1 or claim 2 , wherein said intermediate layer also minimises liquid migrating into said core.
4 . A composition according to claim 3 , wherein said intermediate layer prevents liquid migrating into said core.
5 . A composition according to any of the preceding claims, wherein the liquid present in the core comprises one or more natural or synthetic flavouring agents.
6 . A composition according to any of the preceding claims, wherein the matrix layer of the core comprises one or more water soluble hydrocolloids.
7 . A composition according to any of the preceding claims, wherein the core has a diameter of between 3 and 10 mm.
8 . A composition according to any of the preceding claims, wherein the intermediate layer comprises arabic gum.
9 . A composition according to claim 8 , wherein the intermediate layer is entirely composed of arabic gum.
10 . A composition according to any of the preceding claims, wherein the composition has a weight of 1.5 grams or less.
11 . A composition according to any of the preceding claims, wherein said outer layer comprises chewing gum.
12 . A composition according to claim 11 , wherein the chewing gum comprises granules of chewing gum base.
13 . A composition according to any of the preceding claims, wherein said outer layer is further coated with an additional layer in order to provide an outer shell of greater hardness than the said outer layer.
14 . A composition according to claim 13 , wherein the outer shell comprises at least one of sugar or sugar alcohol.
15 . A composition according to claim 14 , wherein the sugar alcohol is maltitol.
16 . A composition according to any of the preceding claims, wherein said composition is manufactured by a method comprising the steps of:
(a) providing the core;
(b) coating said core with one or more intermediate layers; and
(c) coating the resulting product with one or more outer layers.
17 . A method of manufacture of a liquid-filled confectionery composition as described in any of the preceding claims, said method comprising the steps of:
(a) providing a core, wherein said core contains a liquid;
(b) coating said core with one or more intermediate layers; and
(c) coating the resulting product with one or more outer layers.
18 . A method according to claim 17 , wherein the intermediate layer is formed by coating the core with a solution which does not disturb the integrity of the matrix of the core.
19 . A method according to claim 18 , wherein the matrix of the core is water soluble and the intermediate layer is applied in a non-aqueous solution.
20 . A method according to any of claims 17 to 19 , wherein the outer layer comprises granules of chewing gum base prepared by a granulation process, said granulation process comprising the steps of:
(a) mixing gum base ingredients to form the required gum base composition; and
(b) cooling the gum base composition and grinding the gum base into granules.
21 . A method according to claim 20 , wherein the chewing gum granules are selected to be less than 1000 μm in diameter.
22 . A method according to claim 21 , wherein the chewing gum granules are selected to be less than 500 μm in diameter.
23 . A method according to any of claims 17 to 22 , wherein the outer layer comprises a chewable confectionery composition which is coated with a further layer to provide an outer shell, said shell being of greater hardness than said outer layer, said further layer being formed by coating the external surface of the chewable confectionery composition with at least one of a sugar or sugar alcohol syrup, followed by drying.
