Encapsulated flavor and/or fragrance preparations
View Patent ↗This invention relates to encapsulated flavor and/or fragrance preparations and a method for producing same from a spray solution consisting of an aqueous solution of polymeric carriers and emulsified flavors and/or fragrances. The granules have an adjustable particle size of between 0.2 and 2 mm, present even size distribution and a globular shape and are further characterized by a high concentration and high retention of volatile flavors.
1. Process for producing encapsulated flavoring and/or perfume preparation granules comprising:
fluidized-bed spray agglomeration, in which a flavoring preparation and/or perfume preparation is sprayed into a fluidized bed, wherein
the mean residence time after the flavoring preparation and/or perfumed preparation is sprayed in is less than 20 minutes in the fluidized bed;
the flavorings and perfumes are selected from the group consisting of berries, citrus, pome fruit, cheese, meat, fish, seafood, spices, herbs, vegetables, coffee, chocolate, mint, tobacco, wood and flowers;
the flavoring loadings are in the range from 1 to 25% by weight, and
the retentions of the flavorings during the agglomeration process are in the range of the 60 to 90% by weight; and
forming internal granulation nuclei in the fluidized bed during said fluidized-bed spray agglomeration step, wherein resulting encapsulated flavoring and/or perfume preparation granules comprise coated internal granulation nuclei, wherein said encapsulated flavoring and/or perfume preparation granules exiting said fluidized bed are dust-fee, wherein said fluidized-bed spray agglomeration is carried out continuously.
2. The process according to claim 1 , wherein the fluidized bed has a bed-height of less than 10 cm.
3. The process according to claim 1 , wherein the granules of the desired particle size are separated from the fluidized bed by sifter.
4. The process according to claim 1 , wherein encapsulated flavoring and/or perfume preparation granules, after their production, are provided with an external coat by spraying a liquid coating material on the granules.
5. The process according to claim 1 , wherein the flavorings and/or perfumes are used in the form of an emulsion produced by mixing the flavorings and/or perfumes with water and a polymeric carrier.
6. Process according to claim 5 , wherein the polymeric carriers used is a hydrolyzed or modified starch.
7. Process according to claim 5 , wherein the flavoring emulsion and/or perfume emulsion comprises as additives food dyes or cosmetic dyes, sweeteners, anti-oxidants, edible acids, flavor-enhancing substances, vitamins, minerals and/or juice concentrates.
8. The process according to claim 1 , further comprising:
retaining spray-agglomeration granules in the fluidized bed until the spray-agglomeration granules reach a desired size.
9. The process according to claim 8 , wherein a zig-zag sifter is used for said retaining step.
10. The process according to claim 1 , wherein said fluidized-bed process is of the internal nucleation variant, where external nuclei are not added to the fluidized-bed.
