花生和核桃是堅果品類中的元老;事實上,這兩位元老很受人歡迎;比如,人們會將花生稱作是長生果,核桃被稱為“萬歲子”。到底是為什么會這么受歡迎呢?凈信在這里告訴你們幾個關于花生核桃的小秘密。

據現代醫學考證,花生和核桃具有很高的營養價值,內含豐富的脂肪和蛋白質。礦物質含量也很豐富,特別是含有人體必須的氨基酸,有促進腦細胞發育,增強記憶的功能;花生與核桃的蛋白質含量多在12%~36%,脂肪含量可達40%以上,碳水化合物則在15%以下。而且富含鉀、鎂、鋅、銅、硒等各種礦物質、B族維生素、維生素E以及豐富的不飽和脂肪酸。相比之下核桃的營養價值要高一點。就營養成分比較來說,核桃營養價值是花生的6倍。

堅果中充滿了對心臟和心血管系統有益的物質。一些研究也表明,堅果具有對抗癌癥的作用;在最新的研究中,發現堅果之所以對健康有著積極的影響,因為它們參與激活了機體去除活性氧的自身防御(活性氧由紫外線照射、各種化學物質或不同食物代謝物產生,能夠造成DNA損傷,導致癌癥的發生)。

科研工作者們將花生與核桃在研磨儀中進行研磨使其核心物質(主要是蛋白質等)析出,再在試管中進行人工“消化”;最后分析“消化產物”對癌細胞系的影響。研究發現:被處理的細胞中,保護性的過氧化氫酶和超氧化物歧化酶的活性增加了;而且消化產物誘導了癌細胞的程序性細胞死亡。科研人員表示,機體有一系列使活性氧變得“無害”的保護機制,而堅果及其所含的物質刺激了這些機制。

凈信JXFSTPRP-II全自動液氮冷凍研磨儀
JXFSTPRP-II全自動液氮冷凍研磨儀應用原理:使用超低溫液氮作為降溫介質,使物料在脆化點溫度附近進行研磨,能夠粉碎熱敏感性物質、多種動植物組織、微生物、橡膠、塑料、食品、藥品、煤炭、油頁巖、蠟制品、PE、PS、紡織品、樹脂等及在常溫下呈韌性、難以粉碎的物質;在低溫環境下可以保持物料的各種特性不變,如:可以粉碎各種高分子材料、可以保持各種食品的原始特性、營養成分、氣味等,設備經過設計優化,操作簡單,能耗低、效率高,先進的氮氣回路系統可以最大化利用低溫液氮。
研磨實例:
1、將花生、核桃樣本放入研磨罐內,加入研磨珠蓋好;
2、放入液氮里浸泡數分鐘;
3、把浸泡好的研磨罐放置在JXFSTPRP-II全自動液氮研磨儀上;
4、按照要求設定好相關參數
5、開始進行樣品的研磨
6、取出研磨后樣品(PS:如果室溫較高,取出樣品需快速冷藏)
