    • A process for stabilizing an aroma-providing component such as coffee aroma against loss or degradation of desirable flavor or sensory characteristics of its aroma during storage. The aroma-providing component is associated with a stabilizing agent in an amount effective to chemically interact with undesirable compounds to form a stabilized aroma-providing component which (a) retains a significant portion of one or more of the desirable flavor or sensory characteristics of the aroma in the aroma-containing component during storage, or (b) reduces off flavor generation during storage of the aroma-providing component. The stabilizing agent preferably is a nucleophile that contains sulfur or nitrogen, such as sulfur dioxide, sulfites, compounds that contain or generate thiols, amines or amino acids, cysteine, gluathione or an enzyme. The stabilized aroma-providing component retains the desirable flavor and sensory characteristics of the aroma for a time period of at least six months to one year or longer.
    • 一种芳香提供成分如咖啡香气的稳定化方法,以防止在保存期间香味所需风味或感官特征的损失或降解。 提供芳香的组分与稳定剂相关联,其量有效地与不希望的化合物进行化学相互作用以形成稳定的提供香味的组分,其中(a)保留一个或多个所需风味或感官特征中的一种或多种 在保存期间含芳香组分的香气,或(b)减少在提供芳香组分的储存过程中产生的风味。 稳定剂优选是含有硫或氮的亲核试剂,例如二氧化硫,亚硫酸盐,含有或产生硫醇,胺或氨基酸的化合物,半胱氨酸,gluathione或酶。 稳定的提供香味的组分在至少六个月至一年或更长的时间内保持香味的期望风味和感官特征。
