Abstract

A process for the production of granules of dates, comprising the steps of decortifying the dates, blanching the cored dates to produce a date mash and drying the date mashes using fluidized bed technology such that dried date mash is in the form of granules. The invention further relates to a corresponding granules of dates and to processes for the production of beverages and foods using such granules.

Description

The The invention relates to a process for producing a granulate from dates, a granulate produced by the method as well as a process for making beverages as well as dry ones Foods using such granules after the Claims 1, 10, 11 and 12.

Datteln have been known for millennia and are due to your healthy Ingredients, namely vitamins, minerals, trace elements and fiber especially in Arab countries appreciated and there referred to as "bread of the desert" the export intended as dried dates fruit or fruit pieces are usually gutted, up on dried and packaged at a moisture content of about 20%. The dates then continue to dry and it follows Hardy for some time, hard-to-chew fruit or pieces of fruit.

In Arab countries, it is also known, a kind of date paste from crushed dates to produce, however, due to their remaining water content and its pasty character, as well as fresh fruits, is perishable and not arbitrary stored for a long time and can not be easily processed.

From a completely different technical field, namely that of the brewing industry, it is also known to granulate liquid or pasty substances by applying the well-known from the pharmacological field known as fluidized bed technology. That's how it describes EP 1 385 931 B1 a process for the production of dried original wort from liquid, on concentrated wort, wherein the liquid wort is granulated by applying the fluidized bed technique.

Of the present invention is based on the object of dates durable, cost-effective over long distances too transporting, easy to process, pourable Concentrate produce. Here are the ingredients of the date over preserved long periods and the fruit in a microbiological stable, value-added product to be transformed easily transported and easily processed.

Solved This object is achieved by the method according to claim 1. The resulting granules is the subject of claim 10. Procedure for the recycling of such granules for the production a drink or a dry foodstuff Objects of claims 11 and 12, respectively.

In their simplest embodiment will be according to the invention Date fruits first gutted and then fine using known industrial processes and devices pureed, wherein in this process step or at this connected also can connect a screening. thereupon the resulting date mash is dried, but not in one known drying method, which is only a fine powder would produce which is hardly pourable, is very hygroscopic and easily glued, but by way of so-called fluidized bed technology. This drying process leads to the emergence of a granulate whose individual components such as an onion composed of several layers. The granules is relatively coarse-grained and easy to pour. It does not stick and is not or only slightly hygroscopic.

The Ingredients contained in the date mash, in particular the nutritionally important fiber, amino acids, Minerals and trace elements remain in the granulation by the Fluidized technology obtained and are encapsulated in the granules, survive So also a long storage and transport of the granules. The Dattelgranulat can be stored as bulk material in silos and transported in transport silos, what an industrial Processing brings great benefits. The date granules is free flowing and thus at the vending machine for the beverage production advantageous. Also an application and marketing in the instant dry area is possible.

Under The term "date mash" is used in the sense of the present Invention understood a mash in the brewing technical sense, ie a product which is in liquid to pasty Form is present. In addition, in the present invention also of Date mash spoken when in addition to the starting product, so the date fruit, even more plant and / or animal Products are added as it is the subject of some subclaims is.

Of the Use of fluidized bed technology, as in the present invention fluid bed drying, fluidized bed granulation, fluidized bed granulation, spin coating and fluidized bed agglomeration. The expert, this Procedures are known, it is known that by suitable Setting the process parameters also the grain size, the Bulk density and the dissolving behavior of the granules can be varied and this with one or more further layers of the same or other substances coated and thus can be refined if necessary.

In particular embodiments of the invention, as subject of the dependent Ansprü In the process of blending, the temperature can be increased by supplying heat and / or water or other liquids can be added. These measures will be taken especially if you want to influence the viscosity of the product.

When Raw material can be either mature, dried or also fresh or only dried dates can be used.

Further can the date mash, as mentioned above, a number of additions are added, such as B. original wort from beer production in liquid or in solid form, e.g. B in the form of granules, or flours, in particular wheat flour or vegetable or animal products, z. Figs, milk, especially camel's milk or fatty products herbal or animal provenance.

By Application of the present invention may be a Dateanbau and the Processing of dates done centrally, with the final product a valued, dried, free-flowing Dattelgranulat is what all valuable ingredients of the date has encapsulated beneficial, which is microbiologically stable therefore without change / aging of these ingredients over easily stored for a long time, transported and as a bulk material can be processed.

object The invention is also a date granules, which accordingly the method claims was produced and also a Process for making a drink and a dry one Food using such date granules.

to Production of a beverage is the date granules - in the simplest variant - just a liquid added and stirred in, being as a liquid preferably water is used. By adding suitable microorganisms can this liquid also be further transformed, for. B. by means of a non-alcoholic fermentation to date vinegar.

Further can the granules of date be used to produce a dry (solid) Foodstuff in dry or dissolved form Food recipe be added, for. B. a bar, a Snack, a Semmelteig or an ice cream, or exclusively the granules themselves are pressed into a specific shape, z. B. in bar or cube shape.
