Abstract:
Method for manufacturing a packed product, comprising the steps of: a) bringing a product into a superheated steam atmosphere with an O 2 content of maximum 10 vol.-%, a pressure of between 950 mbar and 1100 mbar and a temperature of minimmn 100°C, b) making available a packing container in the steam atmosphere and filling the packing container with a predetermined quantity of the product, wherein a residual volume of the packing container not filled with product is filled with the steam atmosphere, c) replacing at least 50% of the residual volume of steam atmosphere in the packing container by a sterile inert gas, d) sealing the packing container, and e) cooling the packing container and the product contained therein to a temperature of between 10°C and 25°C.
Abstract:
Process for the treatment of an aqueous composition of algae, comprising the addition to said composition of at least one bicarbonate, in a total amount, relative to the amount of dry matter of the composition before addition of the bicarbonate, of at least 0.5% by weight and of at most 8% by weight.
Abstract:
The invention relates to a process for dehydrating a water- containing medium, said medium being a pressurized gas having a pressure of at least 0.5 MPa, said process comprising: - contacting the water-containing medium with a dry ionic liquid choline salt to dehydrate the water-containing medium; and - separating a dehydrated medium from the hydrated ionic liquid choline salt. Ionic liquid choline salts offer the advantage that they can be regenerated very easily as they are surprisingly heat-stable. Furthermore, these liquid choline salts offer the advantage that they are non-toxic and largely inert. Thus, these ionic liquid choline salts can suitably be used to dehydrate water-containing media that are subsequently employed in the production of foodstuffs, beverages, nutritional formulations, pharmaceutical preparations etc.
Abstract:
A dehydrating agent comprising a cyclic tetra-saccharide, which is defined in the specification, as an effective component; a method for dehydrating a moist article, characterized in that the moist article is incorporated into, is contacted with, or is caused to be present with a cyclic tetra-saccharide; and a dehydrated article obtained by the method. The cyclic tetra-saccharide is a non-reducing saccharide and therefore can be used for dehydrating an article with no deterioration of the quality of the article.
Abstract:
L'invention concerne un procédé de traitement de végétaux fraîchement récoltés, notamment d'herbes ou plantes aromatiques, caractérisé en ce qu'il comprend les étapes consistant à ajouter et mélanger à des morceaux consommables de végétaux des dépresseurs d'activité d'eau ; congeler le mélange ainsi obtenu ; extraire du mélange une quantité d'eau déterminée par sublimation et interrompre le processus au tout début ou en cours de dessiccation primaire pour que le mélange présente des morceaux de végétaux secs et des morceaux de végétaux encore gelés ou plus ou moins humides ; mélanger, de façon homogène, le mélange de morceaux de végétaux ainsi obtenu pour permettre une migration d'eau des morceaux gelés ou plus ou moins humides vers les morceaux secs.
Abstract:
The present invention includes compositions and drying methods for preserving sensitive bioactive materials, such as peptides, proteins, hormones, nucleic acids, antibodies, drugs vaccines, yeast, bacteria (probiotic or otherwise), viruses and/or cell suspensions, in storage. The compositions include a carbohydrates component and a glass enhancer component, wherein the carbohydrate component includes a mixture of di-, oligo- and polysaccharides and the glass enhancer includes ions of organic acid and protein hydrolysates. The composition is prepared by dispersing all the solid components in a solution and then snap-frozen to form small beads, strings or droplets. The preferred drying method of the frozen beads, strings or droplets is initiated by a short purging and structure stabilizing step of the frozen particles under a vacuum pressure of less than 2000 mTORR and at a desired temperature. During the secondary and final drying step of the material a full vacuum pressure and elevated temperature are applied, to achieve a final desirable water activity of the dry material.
