    • 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.
    • 本发明提供了一种生产高品质的鲜活性番茄部分的有效方法,所述方法包括以下步骤:a。提供番茄血清; b将番茄血清分成两部分或更多部分,包括番茄红素贫乏部分和番茄红素富集部分; c。将番茄红素贫化部分浓缩至至少10°白利糖度; d。将浓缩的番茄红素部分色谱分离成两个或更多个级分,包括重量比为谷氨酸:X的单糖和重量比为谷氨酸的单糖级分:Y的单糖,其中X:Y的比例超过 20; 特别地,浓缩粗油部分; f。将粗油馏分色谱分离成两个或多个馏分,包括重量比为谷氨酸盐:K柠檬酸盐和柠檬酸盐级分的重量比为谷氨酸盐:柠檬酸盐的L的清洁的鲜味组分,其中K:L的比例超过10 本发明还涉及包含谷氨酸,天冬氨酸和蔗糖的番茄分离物; 其中谷氨酸盐:柠檬酸盐的重量比超过2,并且其中谷氨酸盐,5'- AMP,天冬氨酸和焦谷氨酸一起占番茄分离物中所含干物质的至少15重量%。
