Description
It is a small decious tree or shrub reaching a height of 5–10 metres (16–33 ft), usually with thorny branches. The leaves are shiny-green, ovate-acute, 2–7 centimetres (0.79–2.8 in) wide and 1–3 centimetres (0.39–1.2 in) broad, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, 5 millimetres (0.20 in) wide, with five inconspicuous yellowish-green petals. The fruit is an edible ovaldrupe 1.5–3 centimetres (0.59–1.2 in) deep; when immature it is smooth-green, with the consistency and taste of an apple, maturing brown to purplish-black and eventually wrinkled, looking like a small date. There is a single hard stone similar to an olive stone.
Distribution
Its precise natural distribution is uncertain e to extensive cultivation, but is thought to be in southernAsia, between Lebanon, Iran, Pakistan, India, Bangladesh, Nepal (called as Bayar), the Korean peninsula, and southern and central China, and also southeastern Europe though more likely introced there.This plant has been introced in Madagascar and grows as an invasive species in the western part of this island.
Nomenclature
The species has a curious nomenclatural history, e to a combination of botanical naming regulations, and variations in spelling. It was first described scientifically by Carolus Linnaeus as Rhamnus zizyphus, in Species Plantarum in 1753. Later, in 1768, Philip Miller concluded it was sufficiently distinct from Rhamnus to merit separation into a new genus, in which he named it Ziziphus jujube, using Linnaeus' species name for the genus but with a probably accidental single letter spelling difference, 'i' for 'y'; for the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination correctly using the earliest species name (from Linnaeus) with the new genus, Ziziphus zizyphus, is not a tautonym, and was therefore permitted as a botanical name; this combination was made by Hermann Karsten in 1882.] In 2006, a proposal was made to suppress the name Ziziphus zizyphusin favor of Zizyphus jujuba, and this proposal was accepted in 2011. Ziziphus jujuba is thus the correct scientific name for this species.
Cultivation and uses
Jujube was domesticated in South Asia by 9000 BCE. Over 400 cultivars have been selected.
The tree tolerates a wide range of temperatures and rainfall, though it requires hot summers and sufficient water for acceptable fruiting. Unlike most of the other species in the genus, it tolerates fairly cold winters, surviving temperatures down to about −15 °C (5 °F). This enables the jujube to grow in mountain or desert habitats, provided there is access to underground water through the summer. The species Ziziphus jujuba grows in cooler regions of Asia. Five or more other species of Ziziphus are widely distributed in milder climates to hot deserts of Asia and Africa.
In Madagascar, jujube trees grow everywhere in the western part of the island, from the north all the way to the south. It is widely eaten by free ranging zebus, and its seeds grow easily in zebu's feces. It is an invasive species, threatening mostly protected areas.

棗(Ziziphus jujuba Mill.)是原產於我國特有的經濟林樹種,到目前已有三千多年的栽培歷史,食用歷史可追溯到7800年以前。目前,我國棗的年產量佔世界總產量98%以上。
山西省棗樹資源極其豐富,具有得天獨厚的自然條件。其中尤以在歷史上被人們稱之為「山西四大名棗」之一的「壺瓶棗」 為地方古老的優質品種。「壺瓶棗」以其營養豐富,果形與風味獨特,備受消費者青睞。其為鮮食與加工兼備的優良品種,是當前制干加工紅棗中的上乘之品,一直被視為本地區「名優稀特」果品。
【俗諺】中醫理論認為棗具有補脾和胃、益氣生津、調營養、解葯毒、保護肝臟和增強肌力等功效,因而諺語有「日食三粒棗,七十不顯老」之說。
【營養】
1.棗能提高人體免疫力,並可抑制癌細胞:葯理研究發現,紅棗能促進白細胞的生成,降低血清膽固醇,提高血清白蛋白,保護肝臟,紅棗中還含有抑制癌細胞,甚至可使癌細胞向正常細胞轉化的物質。
2.經常食用鮮棗的人很少患膽結石,這是因為鮮棗中豐富的維生素C,使體內多餘的膽固醇轉變為膽汁酸,膽固醇少了,結石形成的概率也就隨之減少。
3.棗中富含鈣和鐵,它們對防治骨質疏鬆產貧血有重要作用,中老年人更年期經常會骨質疏鬆,正在生長發育高峰期的青少年和女性容易發生貧血,大棗對他們會有十分理想的食療作用,其效果通常是葯物不能比擬的。
4.對病後體虛的人也有良好的滋補作用。
5.棗所含的蘆丁,是一種使血管軟化,從而使血壓降低的物質,對高血壓病有防治功效。
6.棗還可以抗過敏、除腥臭怪味、寧心安神、益智健腦、增強食慾。
【宜忌】一般人群均可食用,中老年人、青少年、女性尤宜食用;有宿疾者應慎食,脾胃虛寒者不宜多吃,牙病患者不宜食用棗,便秘患者應慎食,棗忌與海鮮同食。
【食療】棗味甘、性平,入脾、胃經;有補益脾胃,滋養陰血,養心安神,緩和葯性的功效;用於治療脾氣虛所致的食少、泄瀉,陰血虛所致的婦女臟躁證,病後體虛的人食用大棗也有良好的滋補作用。

E. 紅棗的葯理作用
紅棗的功效與作用
1.抗癌抗癌
棗能提高人體免疫力,並可抑制癌細胞。能促進白細胞的生成,降低血清膽固醇,提高血清白蛋白,保護肝臟,紅棗中還含有抑制癌細胞,甚至可使癌細胞向正常細胞轉化的物質。
2.降血壓、降膽固醇
大棗中的維生素P含量為所有果蔬之冠,其具有維持毛細血管通透性,改善微循環從而預防動脈硬化的作用。還可以調節人體代謝、增強免疫力、抗炎、抗變態反應、降低血糖和膽固醇含量等作用;所含蘆丁有保護毛細血管通暢、防止血管壁脆性增加
3.保肝護肝
大棗能提高體內單核細胞的吞噬功能,有保護肝臟、增強體力的作用;大棗中的維生素C,能減輕化學葯物對肝臟的損害,並有促進蛋白質合成,增加血清總蛋白含量的作用。
4.預防骨質疏鬆
對防治骨質疏鬆產貧血有重要作用,中老年人更年期經常會骨質疏鬆,正在生長發育高峰的青少年和女性容易發生貧血,大棗對他們會有十分理想的食療作用,其效果通常是葯物不能比擬的。
5.防治腦供血不足
大棗中的黃酮類物質可以防治腦缺血症並對腦缺血所致的腦組織超微結構損傷有保護作用。
6.防治心血管病
大棗中含有豐富的維生素C、維生素P,對健全毛細血管、維持血管壁彈性,抗動脈粥樣硬化很有益;大棗中含有cAMP,其葯理作用表現為改善人體微循環,擴張冠狀動脈,增加腦和心臟的供血量,減慢心律,降低心肌耗氧量而改善缺血心肌的代謝,故可防治心腦血管病。
7.恢復體力
對病後體虛的人也有良好的滋補作用。
8.預防膽結石
鮮棗中豐富的維生素C,使體內多餘的膽固醇轉變為膽汁酸,膽固醇少了,結石形成的概率也就隨之減少。
紅棗的營養價值
1.鮮棗有較高的熱量,主要源於所含的碳水化合物約23%~28%。
2.鮮棗含有豐富的膳食纖維,維生素和微量元素,大棗中的維生素P含量為所有果蔬之冠。脂肪,澱粉,蘆丁,尼克酸以及礦物質。干棗所含的礦物質和熱量為鮮棗的2~3倍。
紅棗的選購
好的大棗皮色紫紅,顆粒大而均勻、果形短壯圓整,皺紋少,痕跡淺;皮薄核小,肉質厚而細實;如果皺紋多,痕跡深,果形凹癟,則肉質差,為未成熟的鮮棗製成的干品。
如果紅棗的蒂端有穿孔或粘有咖啡色或深褐色的粉末,這說明紅棗已被蟲蛀了,掰開紅棗可看到肉核之間有蟲屎。吃時要將蟲屎、爛棗等剔除干凈。
口嘗味甜,用手將紅棗成把緊捏一下,如感到滑糯又不松泡,說明質細緊實,棗身干,核小;如果甜味差、有酸澀味,用手捏,松軟粗糙,質量就差;要是濕軟而粘手,說明棗身較潮,不耐久貯,易於霉爛變質。
紅棗的存儲
1.開水處理法:把紅棗中混雜的干癟棗和雜質挑出後,放入滾開的水中焯一遍,然後迅速撈出紅棗,淋干水後放在日光下曬干,可以殺滅紅棗表面的細菌,存放在乾燥隔潮的密封容器內,便能避免紅棗生蟲或變質。
2.精鹽法:取有蓋可以密封的陶瓷容器一隻,洗凈晾乾後備用。如果有1000克紅棗,去食用精鹽25克,把鹽放入炒鍋加熱消毒,晾涼後備用。在容器內放入一層紅棗後便放入薄薄一層精鹽,直到把全部紅棗放入後,再在最上面撒一層精鹽,然後蓋蓋封存。由於食用精鹽有殺菌保鮮的功效,保證了紅棗的質量。又因為甜的食物稍加食鹽可以甜中加甜,所以不會使紅棗變咸。
紅棗受風吹後容易干縮、起皺、變色,因此,在地上攤晾時,最好在紅棗上加蓋一層廢舊報紙,防止直接光照和風吹。
紅棗的食用方法
生吃時,棗皮容易滯留在腸道中而不易排出,因此吃棗時應吐棗皮。棗皮中含有豐富的營養成分,燉湯時應連皮一起烹調。過多食用人棗會引起胃酸過多和腹脹。腐爛的大棗在微生物的作用下會產生果酸和甲醇,人吃了爛棗會出現頭暈、視力障礙等中毒反應,重者可危及牛命,所以要引起注意。
F. 描寫紅棗的文章
我的家鄉靈寶,盛產各種各樣的果子:清涼可口的西瓜,白里透紅的蜜桃,玻璃球似的葡萄,肉厚甜脆的蘋果……最吸引我的要數那紅棗了。
; ; ; 春末夏初,那狀似乾枯的棗樹開始露出黃嫩的新芽,初夏,這些新芽便長成橢圓形的葉片。六月多,一棵棵棗樹開滿了黃綠色的棗花,招來了成群的蜜蜂。聽說,棗花蜜是上等的蜜糖,要十來塊錢一斤呢。微風吹過,棗樹下落了一層黃黃的棗花,撿起來一看,棗花有五個瓣,花朵裡面是黃色的花蕊,用鼻子一聞,香氣甜絲絲的,沁人心脾。
; ; ; 花兒落了不久,枝上便結了一顆顆青綠色的小棗,一個個小棗像一串串小銅鈴。七八月,「小銅鈴」由綠變黃,由黃變紅,由淺紅變成紫紅。八月十五,像珍珠、像瑪瑙、像紅寶石一樣的紅棗,在陽光下閃閃發光,那麼招人喜愛。如果你摘下一顆又紅又大的棗,輕輕咬一口,能甜到心裡,吃了一顆還想吃第二顆。最好玩的要數那「下棗」了,大人們在樹上搖,或用棍子打,我們孩子則在樹下拾,棗兒落下來,像冰雹一樣打在頭上,但沒一個人喊疼哭叫,反而嬉笑著抱著頭從樹下跑出來。
; ; ; 棗不僅可以生吃,還可以蒸、曬、煮呢 !尤其蒸熟的棗,吃起來別有一番風味。先把棗洗干凈盛在碗里,倒點水,撒上糖,再給鍋里添上水,把碗放到鍋中, 把鍋坐在火上,過半小時,棗就蒸熟了。揭開鍋,端出碗,那股甜蜜的清香立刻會讓你猛吞口水。棗曬好後能保存一年,曬好的棗全身通紅,摸起來軟綿綿的。人們常把曬好的棗和江米在一起蒸,蒸出來後紅白相間,讓人垂涎三尺。棗還能做棗飲料、棗泥月餅,中葯上還用棗做葯引子呢……
; ; 啊,紅棗,我愛家鄉的紅棗,愛那朴實無華、植根於黃土之中,無私為人類貢獻出果實的棗樹

I. 關於紅棗果醬的論文!只要格式正確加分!!!
紅棗(Jujube, Chinese date)為鼠李目(Rhamnales)鼠李科(Rhamnaceae)植物棗的的成熟果實富含蛋白質、糖類、膳食纖維、多種氨基酸、胡蘿卜素、VB、Vc和鈣、磷、鐵等礦物質,具有補中益氣養血安神之功效[1,5]。桑椹(Mulberry Fruit)又稱桑果是桑樹(Mores alba. L.)的果實含有豐富的維生素、花青素、有機酸、氨基酸等成分自古以來就作為水果和中葯材被應用[2~3]。這兩種植物果實均已被國家衛生部列人「既是食品又是葯品」的名單集葯、食、補三大功能為一體而且都是中醫所推崇的補血益氣之上品適宜於加工各種功能性食品。目前我國市場上流通的果醬製品主要是採用傳統工藝生產的高糖型果醬含糖量高達60%以上口感甜膩已日益不適應消費者追求健康食品(低糖、 收稿日期2008-06-03 項目資助廣東省科技攻關項目編號: 2006B20401013 作者簡介鄒宇曉1973-女副研究員研究方向為農產品加工與蠶桑資源綜合利用 低鹽、低脂肪)的消費趨勢。低糖型、口感清爽、功能果醬的開發是果醬產業發展的新方向市場潛力巨大[6,7]。因此本實驗選用桑椹和紅棗為原料重點研究了果醬的糖酸配比、增稠劑選擇與使用等工藝開發出一種具有補血益氣功能的風味果醬產品。 1 材料與方法 1.1 原輔材料 原料桑椹品種為「大10」采自寶桑園花都基地紅棗市售一級紅棗白砂糖(符合 GB1445-2000優級品標准) 輔料低甲氧基果膠(LMP)、CaCl2、檸檬酸等均為食品級。 1.2 主要機械設備 洗果機、夾層鍋、打漿機、膠體磨、調配罐、夾層鍋、打漿機、膠體磨、滅菌設備、阿貝折光儀、旋轉粘度計等。
現代食品科技 Modern Food Science and Technology 2008, Vol.24, No.11 1132 因子依次為ABC即混合果漿添加量蔗糖的使用量檸檬酸的使用量。各因素最佳組合水平為混合果漿添加量50%蔗糖30%檸檬酸0.1%。 2.2 增稠劑對果醬凝膠效果的影響 低糖果醬形成凝膠的機制與高糖果醬不同高糖果醬是在高糖60%~65%、高酸pH值為2~3和高甲氧基果膠存在時可形成穩定的凝膠。而低甲氧基果膠LMP必須在二價陽離子(如Ca2+)存在的情況下形成凝膠凝膠的機理是由不同分子鏈的均勻(均一的半乳糖醛酸)區間形成分子間結合區凝膠能力隨DE值果膠分子中的羧基甲酯化程度的減少而增加[3]。影響凝膠最重要的因素為Ca2+濃度。由低甲氧基果膠LMP與Ca2+形成的凝膠在加熱或攪拌後會可逆性地變為液體停止攪拌或冷卻後又能恢復原凝膠狀因此非常適合於加工低糖果醬。對果膠添加量選取 0.6%、0.8%、1.0%三個水平CaCl2添加量選取 0.16%、0.18%、0.20%三個水平進行正交試驗。 表3 增稠劑對低糖果醬凝膠效果的影響 Table 3 Effect of thickening agents on the gel-forming properties of the jam 試驗號 LMP/% CaCl2/% 凝膠效果評分1 0.6 0.16 3 2 0.6 0.18 3 3 0.6 0.2 4 4 0.8 0.16 3 5 0.8 0.18 4 6 0.8 0.2 4 7 1.0 0.16 5 8 1.0 0.18 5 9 1.0 0.2 5 注凝膠效果評分標准為1分-不能凝膠2分-凝膠差果醬中度流散3分-基本形成凝膠果醬緩慢流散4分-形成凝膠果醬輕微流散5分-凝膠良好不流散。 由表3試驗可知當低甲氧基果膠添加量達1.0%時CaCl2的添加量在0.16%~0.20%時均可形成凝膠狀態穩定的果醬產品。 2.3 質量指標 2.3.1 感官指標 色澤紫紅色 滋味酸甜適中口感柔和有桑椹和紅棗的香氣 組織形態呈膠粘狀無果塊無糖結晶無雜物具一定的膠凝性不流散不分泌液汁。 2.3.2 理化指標 可溶性固形物≤40總糖量≤45%膳食纖維1.3~1.5 mg/kg 重金屬含量砷(以As計)≤0.5 mg/kg鉛(以Pb計)≤1.0 mg/kg銅(以Cu計)≤5.0 mg/kg。 2.3.3 微生物指標 細菌總數<100個/mL大腸桿菌數<3個/mL致病菌不得檢出。 3 結論與討論 1低糖桑椹紅棗營養果醬的最佳配方為混合果漿50%蔗糖30%檸檬酸0.1%。影響果醬感官品質的主次因子依次為混合果漿添加量蔗糖的使用量檸檬酸的使用量。 2綜合考慮生產成本及生產工藝選用1.0%低甲氧基果膠和0.16%的CaCl2添加量可獲得色澤鮮艷、酸甜適中、口感柔和、香氣濃郁而且組織狀態細膩凝膠性好的果醬產品。 3實驗中發現輔料添加的先後順序對醬體的持水性有重要影響。輔料的添加順序應嚴格按照濃糖液→氯化鈣→檸檬酸調pH值(3.5)→增稠劑溶液的順序進行。 4傳統果醬製品加工採用常壓、長時間、高溫處理美拉德反應嚴重果醬極易發生褐變。而採用低溫真空濃縮可有效防止由美拉德反應引起的非酶褐變同時有利於產品的營養成分及風味的保持。 參考文獻 [1] 國家葯典委員會.中華人民共和國葯典一部 [S].北京:化學工業出版社,2005:16-17 [2] 劉學銘,肖更生,陳衛東.桑椹的研究與開發進展[J].中草葯, 2001,32(6):569-571 [3] 徐玉娟.低糖桑椹果醬的研製及其營養成分分析[J].食品工業,2001,(4):43-45 [4] 張琪.草莓、胡蘿復合低糖果醬的研製[J].食品科學,2002, 8:110-112 [5] 王桐,王海鷗.低糖紅棗果醬的研製[J].食品科技,2004, 6:39-4l [6] 徐丹,車振明,胡瑞君,等.低糖菠蘿檸檬保健復合果醬的研製[J]..現代食品科技,2006,22(4):183-184 [7] 王婷,郭峰,毛亮,等.紅棗乳酸飲料的研究[J].現代食品科技, 2007, 23(6):42-44,
