Abstract: Process for producing dry, free-flowing, choline chloride-containing powders by atomising an aqueous choline chloride solution, a colloid-free aqueous choline chloride solution being atomised in a counter-current airstream which contains, finely dispersed, a hydrophobic spraying aid added in amounts such that the sprayed choline chloride droplets are coated with 2 to 15% by weight, based on choline chloride calculated as 100%, and the coated particles, if required, are collected in a fluid bed and dried in the gas stream.

Abstract: Procedimiento para la obtención de polvos secos estables, e insolubles en agua caliente, que contienen una o varias vitaminas liposolubles y/o uno o varios carotenoides, que comprende los siguientes pasos de procedimiento: A. Obtención de una dispersión acuosa que contiene: a1) un 2 a un 50 % en peso de al menos una proteína, a2) un 1 a un 30 % en peso de al menos un azúcar, a3) un 0, 2 a un 20 % en peso de al menos una sal inorgánica, a4) un 0, 1 a un 20 % en peso de al menos una vitamina liposoluble y/o al menos un carotenoide, a5) un 5 a un 95 % en peso de agua, referiéndose todos los datos de % en peso al peso total de la dispersión acuosa, y dando por resultado la suma de datos porcentuales de componentes aislados a1) a a5) un 100 %, B. Transformación de esta dispersión en un polvo seco, y C. calentamiento del polvo seco a una temperatura en el intervalo de 55ºC a 180ºC, caracterizado porque se emplea como sal inorgánica a3) fosfatos alcalinos, de modo que la proteína se retícula en este caso en tal medida que el polvo seco, tras introducción en agua de 100ºC, es insoluble en agua al menos durante 3 minutos.

Abstract: In the production of stable, hot water-insoluble dry powder by preparing a dispersion of 2-50 wt.% protein(s), 1-30 wt.% sugar(s), 0.2-20 wt.% inorganic salt(s) (I), 0.1-20 wt.% fat-soluble vitamin(s) and/or carotinoid(s) and 5-95 wt.% water, converting the dispersion to a dry powder and heating at 55-180 degrees C, alkali phosphate is used as (I) to harden the protein to such a degree that the dry powder is insoluble for NOTLESS 3 minutes after addition to water at 100 degrees C. An Independent claim is also included for the dry powder obtained.

Abstract: K-Mg L-ascorbate-2-phosphate (I) is a new cpd. Pref., it has K:Mg atom ratio 1 +/- 0.3 : 1 +/- 0.15. The salt is prepd. by treating aq. soln. of K L-ascorbate-2-phosphate (III) with a medium-acidity cation exchanger which loses its exchange capacity at pH 2-0.5 to produce a soln. of mono-K salt. This is treated with MgO, Mg(OH)2 or MgCO3 to about pH7 and the soln. opt. treated with MeOH or acetone to ppte. (I). USE/ADVANTAGE - Conversion to (I) is used to recover L-ascorbic acid-2-phosphate (II) from phosphorylation mixt. It is produced free of inorganic salts; in well-crystallisation form which is easy to filter, non-hygroscopic and has little tendency to cake or form dust. The use of a medium-acidity resin produces an eluate which is not strongly acid (so does not decompose the product); MgO consumption and salt discharge are reduced, and regeneration times for the resin are Compared with ascorbic acid itself, (II) is more stable to oxygen, heat and hydrolysis, and has universal bioavailability.
