哈密瓜的營養(yǎng)價值，哈密瓜為什么會苦

　　果果小編給大家列舉哈密瓜的幾種營養(yǎng)價值

　　第一，哈密瓜營養(yǎng)成分高。哈密瓜不但風(fēng)味佳，而且富有營養(yǎng)。據(jù)分析，哈密瓜的干物質(zhì)中，含有4.6%-15.8%的糖分，纖維素2.6%-6.7%， 還有蘋果酸、果膠物質(zhì)、維生素A、B、C，尼克酸以及鈣、磷、鐵等元素。其中鐵的含量比雞肉多兩三倍，比牛奶高17倍。

　　第二，哈密瓜有助于治療貧血。食用哈密瓜對人體造血機(jī)能有顯著的促進(jìn)作用，可以用來作為貧血的食療之品。如果常感到身心疲倦、心神焦躁不安或是口臭，食用哈密瓜都能有所改善。

　　第三，哈密瓜周身是寶。除供鮮食，還可制作瓜干、瓜脯、瓜汁。哈密瓜削皮可以用果蔬削皮機(jī)中的大果削皮機(jī)適用于食品規(guī)模加工。瓜蒂瓜籽可入藥治病，瓜皮喂羊能促肥增膘。

　　第四，哈密瓜有利心臟活動。哈密瓜肉中維生素的含量比其它水果也毫不遜色。在哈密瓜鮮瓜肉中，維生素的含量比西瓜多4至7倍，比蘋果高6倍，比杏子也高1.3倍。這些成分，有利于人的心臟和肝臟工作以及腸道系統(tǒng)的活動，促進(jìn)內(nèi)分泌和造血機(jī) 能，加強(qiáng)消化過程。

　　第五，哈密瓜可以用于美容。 哈密瓜籽可用于做精油，富含藥用、美容、保健、生理活性的哈密瓜種子，采取純物理、冷榨方式精制而成。其色澤金黃，滋味清香，還有令人愉快的水果滋味;充分保留了哈密瓜籽中獨(dú)有的藥用、美容、保健營養(yǎng)成分不受破壞。具有超強(qiáng)的抗氧能力，實(shí)屬上等純天然藥用、美容、保健、營養(yǎng)精油，可廣泛應(yīng)用在醫(yī)藥、美容、保健、營養(yǎng)食品等方面。

　　第六，哈密瓜能治理小病。哈密瓜果肉有利小便、止渴、除煩熱、防暑氣等作用，可治發(fā)燒、中暑、口渴、尿路感染、口鼻生瘡等癥狀并且有清涼消暑，除煩熱，生津止渴的作用，是夏季解暑的佳品，查看更多的哈密瓜功效與作用，請移至《哈密瓜的功效與作用》一文。

　　哈密瓜為什么會苦

　　哈密瓜產(chǎn)自新疆，成熟的哈密瓜果肉綿軟，吃起來甜蜜多汁，很多人都喜歡吃，但有網(wǎng)友反映，有的時候挑選到一些哈密瓜吃起來是苦的，哈密瓜為什么會苦呢？哈密瓜發(fā)苦是不是正常呢？下面我們一起來了解！

　　一般來說，各類的甜瓜“坐果”的過程可分為自然授粉和人為干預(yù)兩類。但如果遇到環(huán)境異常時，則需對果蔬進(jìn)行人工干預(yù)，比如會使用一些植物激素使其快速成熟。人工干預(yù)時若未科學(xué)用藥就會產(chǎn)生外表看似成熟內(nèi)部未成熟的狀況，即通常所說的“催熟”。

　　被“催熟”的瓜類糖度積累不足，果肉有些許苦味。因此在遇到發(fā)苦的哈密瓜時，可能是因?yàn)榇呤靹┰谧魉睿虼藶榻】悼紤]，如果買到苦味的哈密瓜就不要吃了，以免造成身體不適。

　　哈密瓜要怎么挑才不苦？如何挑選出新鮮的哈密瓜呢？

　　首先，在挑選哈密瓜時，要先看哈密瓜的顏色，哈密瓜的顏色通常為果綠色帶網(wǎng)紋的，也有金黃色的、花青色的等等。深黃色的比淺色的稍甜一些。

　　其次，在挑選哈密瓜時，用鼻子聞一聞，一般有香味的，成熟度適中。沒有香味或香味淡泊的，是成熟度較差的，這種瓜可以放些時候再吃。

　　再者，在挑選哈密瓜時，可以用手摸一摸，如果瓜身堅實(shí)微軟，這種瓜成熟度就比較適中。如果太硬則表示不太熟，太軟就是成熟過度。

　　除此之外，挑選哈密瓜還有最有效的一個方法：看瓜皮上面有沒有疤痕。疤痕越老的哈密瓜就越甜。最好的哈密瓜就是那個疤痕已經(jīng)裂開，雖然看上去難看，但是這種哈密瓜的甜度高，口感好。而相反，越是賣相好，漂亮的沒疤痕的哈密瓜往往是生的，不好吃。所以瓜的紋路越多，越丑，就越好吃。

　　哈密瓜雖然營養(yǎng)價值豐富，但是各位果友在挑選的時候，如果遇到苦的哈密瓜最好不要食用哦。學(xué)會生活，做生活的主人。
