摘要:
There are provided a flavor enhancing agent which is capable of selectively enhancing the flavor of a flavoring of interest, as well as a flavoring composition and a drink that contain the agent and which are enhanced in flavor. Specifically, a polymerized catechin is used with a flavoring.
摘要:
The present invention relates to aspartame-containing acidic beverages, and also relates to acidic beverages designed to prevent a storage-induced reduction in the sweetness of aspartame, which comprise a polymerized polyphenol (particularly a polymerized catechin). The present invention further relates to a method for preventing a storage-induced reduction in the sweetness of aspartame in aspartame-containing acidic beverages by using a polymerized polyphenol (particularly a polymerized catechin).

摘要:
A method for purifying an .alpha.-L-aspartyl-L- phenylalanine lower alkyl ester containing impurities. The .alpha.-L-aspartyl-L-phenylalanine lower alkyl ester is brought into contact with a Cl-type anion exchange resin in an aqueous medium to have the impurities adsorbed by the anion exchange resin. The impurities contained in the .alpha.-L-aspartyl-L-phenylalanine lower ester, particularly diketopiperazine and .alpha.-L-aspartyl-L-phenylalanine are selectively and easily removed. The desired matter thus can be easily recovered and disposal of waste liquid, etc. can also be carried out without difficulty.

摘要:
The present invention aims to provide a food or drink having an improved sharpness in an aftertaste without reduction in its peak sweetness. According to the present invention, a food or drink containing a sweetener in which sweetness persisting as an unpalatable aftertaste is suppressed, and which retains a nearly intact degree of sweetness of the sweetener at its peak can be obtained by adding a polymerized polyphenol, particularly, a polymerized catechin, which is a polymerized polyphenol derived from tea, to the food or drink.
摘要:
Novel compositions are provided that exhibit immunomodulatory actions such as an immunostimulating action and an anti-allergic action. Compositions are provided in which Kombu fermented with lactic acid bacteria is contained either alone or in combination with sesame and soybean(s) that have been fermented with lactic acid bacteria. The compositions enable nutrients to be absorbed in a balanced way, feature high safety, and have superior immunomodulatory actions.
摘要:
The invention provides a composition comprising novel lactic acid bacteria having immunoregulating activities. Specifically, the invention provides food, drinks or medicaments containing novel lactic acid bacteria separated from “Shibazuke,” one kind of traditional Kyoto pickles, and having immunoregulating activities. The lactic acid bacteria belong to Lactobacillus pentosus and have a weak assimilating activity or no assimilating activity for glycerol.
