柿（Persimmon或kaki）是柿树属的果实，最常见的品种是柿子，又名亚洲柿或日本柿。与番茄相似，柿不会被视为浆果，但在形态学的角度上，它是浆果的一种，加工品常用来制成柿饼。

相传300多年前,李自成称王西安后，临潼老百姓用火晶柿子拌上面粉，烙成柿子面饼慰劳义军,很受义军将士称道。后来，为了纪念李自成及其起义军，每年柿子熟了，临潼百姓家家户户都要烙些柿面饼吃。天长日久，就演变成了今天的黄桂柿子饼。在中华历史人们种柿子（学名：Diospyros）已有一千年历史，柿子，又名朱果种。柿树，举世公认为起源于中国的古老树种，18世纪之后再传到传到南欧、美国、日本。柿子的品种有1000多种，以味道划分为甜柿和涩柿两大类为主，前者成熟时已经脱涩，后者需要人工脱涩，如今日中国、日本、韩国和巴西是世界的主要产地。**北埔是新竹地区柿树栽种面积最大的乡镇，其实北埔的柿子产量并不多，制作柿饼的原料主要来自嘉义县番路乡所种植的柿子，而番路乡除了将柿子外销之外，本身亦产柿饼；而**柿子最多应该是而**柿子大部份集中在嘉义、台中、**等地。**及新竹以石柿为代表，适合制成柿饼，台中的四周柿普遍处理成「软柿」食用，嘉义番路乡的牛心柿又名「水柿、脆柿」则作硬柿食用糖度约11～13度果实大产量也最大。

The persimmon /pərˈsɪmən/ (sometimes spelled persimon) is the edible fruit of a number of species of trees in the genus Diospyros. Diospyros is in the family Ebenaceae. The most widely cultivated species is the Oriental or Japanese persimmon, Diospyros kaki. In color, the ripe fruit of the cultivated strains range from light yellow-orange to dark red-orange depending on the species and variety. They similarly vary in size from 1.5 to 9 cm (0.5 to 4 in) in diameter, and in shape the varieties may be spherical, acorn-, or pumpkin-shaped. The calyx generally remains attached to the fruit after harvesting, but becomes easy to remove once the fruit is ripe. The ripe fruit has a high glucose content. The protein content is low, but it has a balanced protein profile. Persimmon fruits have been put to various medicinal and chemical uses.
