摘要：
The invention provides an efficient method for producing ahigh 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 Xand 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.
