Abstract

PURPOSE:To enable the utilization of tea extract as a food raw material by compounding a tea extract with a cyclodextrin and/or a peptide. CONSTITUTION:The objective composition containing tea extract is composed of a tea extract and a cyclodextrin and/or a peptide. The composition can be added to e.g. a liquid medicine, juice, biscuit, cookie or jelly. There is no particular restriction on the kind of tea, and raw tea leaves or a processed tea such as green tea, black tea and oolong tea may be used as the tea. The extraction if preferably carried out with water. The water used in the extraction may be hot or cold, however, hot-water extraction is preferable to improve the extraction efficiency. The extraction product may be the extracted liquid or its dried product. The amount of each component in a food containing the above composition is preferably 0.5-4% for the tea extract (in terms of dried material), 1-16% for cyclodextrin and, in the case of combined use with a peptide, about 0.5-6% of peptide.
