20130259987 | REFINED PLANT ISOLATES AND PROCESS FOR THE MANUFACTURE OF A FUNCTIONAL FOOD INGREDIENT FROM SUCH PLANT ISOLATE - The present invention is concerned with providing refined plant isolates that can be used as starting materials for the production of functional food ingredients, such as taste enhancers, through an isolation process that employs ion exclusion chromatography. More particularly, the present invention provides a refined plant isolate comprising at least 30% by weight of dry matter of water soluble plant components selected from fructose, glucose, proteinaceous matter of plant origin, acids and potassium, said isolate further being characterized in that at a concentration of 40° Brix the isolate: •contains at least 0.3 wt % of glutamate; •contains at least 500 ppm of K | 10-03-2013 |
20150125581 | UMAMI-ACTIVE TOMATO FRACTION - The invention provides an efficient method for producing a high quality umami-active tomato fraction, said process comprising the steps of: a. providing a tomato serum; b. separating the tomato serum into two or more portions, including a lycopene-depleted portion and a lycopene-enriched portion; c. concentrating the lycopene-depleted portion to at least 10° Brix; d. chromatographically fractionating the concentrated lycopene-depleted portion into two or more fractions, including a crude umami fraction with a weight ratio glutamate:monosaccharide of X and a monosaccharide fraction with a weight ratio glutamate:monosaccharide of Y, wherein the ratio X:Y exceeds 20; e. optionally, concentrating the crude umami fraction; f. chromatographically fractionating the crude umami fraction into two or more fractions, including a clean umami fraction with a weight ratio glutamate:citrate of K and a citrate fraction with a weight ratio glutamate:citrate of L, wherein the ratio K:L exceeds 10. The invention further relates to a tomato isolate comprising glutamate, aspartate and sucrose; wherein the weight ratio glutamate:citrate exceeds 2 and wherein glutamate, 5′-AMP, aspartate and pyroglutamate together represent at least 15 wt. % of the dry matter contained in the tomato isolate. | 05-07-2015 |
20150231528 | METHOD AND APPARATUS FOR MULTI COLUMN CHROMATOGRAPHIC PURIFICATION - A method for separating a feed mixture comprising at least two solutes by an intermittent multi column chromatography process with a basic step N performed in a predetermined switching time period. Basic step N comprises two sub steps which are carried out sequentially according to a predetermined step ratio. In sub step one inlet ports and outlet ports are open, a desorbent and a feed mixture enters upstream of a first and a third section. A first outlet stream comprising the desorbent and at least one solute is withdrawn downstream of the first section a second outlet stream comprising the desorbent and at least a further solute is withdrawn downstream of a the third section. In sub step two inlet ports and outlet ports are closed, a fluid stream comprising the desorbent part of the feed mixture circulates through three sections in a closed loop. | 08-20-2015 |
