探索 E1520:食品及其他領域中的丙二醇

In the world of food additives, E1520 (also known as propylene glycol) is a versatile compound with a wide range of applications. In addition to the culinary field, propylene glycol is widely used in various industries due to its unique properties. In this article, we'll delve into the details of E1520, exploring its properties, applications and role as a multi-functional additive.

chemical composition:

Propylene glycol is a synthetic organic compound with the chemical formula C3H8O2. It is a clear, colorless, odorless alcohol.

Production Process:

Propylene glycol is produced by the hydration of propylene oxide, a reaction that produces compounds suitable for a wide range of applications.

Properties of propylene glycol:

Hygroscopicity:

Propylene glycol is hygroscopic, meaning it attracts and retains water molecules. This property makes it effective in preventing the formation of ice crystals in frozen foods.

Low freezing point:

Its low freezing point makes it useful in the production of ice cream and other frozen desserts, helping to maintain a smooth and creamy texture.

Solvent properties:

Propylene glycol is used as a solvent and can dissolve a variety of substances. This property makes it valuable in the formulation of flavorings, colors and food additives.

Applications of E1520:

Food and Beverage Industry:

Propylene glycol is commonly used as a humectant, stabilizer and thickener in the food and beverage industry. It is found in products such as salad dressings, baked goods and beverages.

drug:

In the pharmaceutical industry, propylene glycol is used as a solvent for oral and injectable drugs. Its ability to dissolve a variety of substances makes it a versatile choice.

Cosmetics and personal care products:

Due to its moisturizing properties, propylene glycol is a common ingredient in cosmetics and personal care products such as lotions, shampoos and deodorants.

Industrial applications:

In addition to the food and personal care sectors, propylene glycol is used in antifreeze formulations, aircraft de-icers and plastic production.

Security considerations:

Generally Recognized as Safe (GRAS):

According to regulatory guidance, propylene glycol is generally considered safe when used in food and pharmaceutical applications.

Allergies and Sensitivities:

Although rare, some people may be allergic or sensitive to propylene glycol. For those with known sensitivities, it is important to be aware of its presence in products.

in conclusion:

E1520, or propylene glycol, is a remarkable compound that transcends industries from food and pharmaceuticals to cosmetics. Its unique combination of properties, including low freezing point and hygroscopicity, make it a popular additive with a variety of applications. As consumers, understanding the effects and safety considerations of propylene glycol allows us to make informed choices and appreciate its contribution to the variety of products we encounter every day.

癌症如何擴散:從一個器官走到另一個器官的旅程

癌症如何擴散:從一個器官走到另一個器官的旅程

癌症最令人畏懼的地方,不單在於原發腫瘤本身,而是它能夠 轉移(Metastasis) —— 由原本的器官擴散至身體其他部位。事實上,大多數癌症致命的原因,並非來自腫瘤的「原居地」,而是因為它在其他重要器官(如腦、肝、骨、肺)形成了新的腫瘤。

腦癌種類全面介紹|常見類型與特徵

腦癌(Brain Cancer)泛指源自腦部或蔓延至腦部的惡性腫瘤。臨床上可分為兩大類: 原發性腦腫瘤(Primary Brain Tumors):由腦部細胞本身變異而成。 繼發性腦腫瘤(Secondary / Metastatic Brain Tumors):由其他器官的癌細胞(如肺...
死亡氣味 :科學如何理解生命最後的氣息

死亡氣味 :科學如何理解生命最後的氣息

人類死亡後,身體嘅代謝同細胞運作會急劇改變,隨住時間推進,組織開始分解,產生一系列特有嘅氣味化合物。呢種 死亡氣味 (Odor of Death) 唔單止係動物可以嗅到,亦成為法醫學 (Forensic Science) 研究嘅重要領域。甚至有人提出,狗可能能夠嗅到人「臨終前」嘅早期氣味改變。

狗隻能否嗅出疾病甚至死亡?——從嗅覺科學到臨床研究

人類同狗相處幾千年,唔少人都曾經觀察到:狗似乎「知道」主人唔舒服,甚至有人報告狗會喺主人臨終前出現異常行為。呢啲現象令科學家開始研究:狗隻係咪真係可以嗅出疾病,甚至察覺死亡徵兆?

答案係:狗確實能透過超強嗅覺 (Olfaction) 偵測身體嘅代謝變化,從癌症、糖尿病,到感染性疾病。但關於「臨終氣味」嘅研究仍然有限,更多係臨床觀察。

幻覺:大腦點樣自己製造「假影像」

幻覺 (Hallucinations) 並唔係靈異現象,而係一種 大腦自我製造影像或感覺 嘅過程。當冇外界刺激存在,但大腦卻產生「真實感受」時,就叫幻覺。研究指出,幻覺源於 大腦訊號錯亂神經傳導物質失衡,甚至同 睡眠失調 有密切關係。

心理學上的「預知錯覺」:點解我哋以為自己可以預測未來?

好多時候,我哋都會有種感覺:「咦!我早就預測到會發生!」,甚至覺得自己擁有「第六感」。但從心理學角度睇,呢種「預知」其實並唔係超能力,而係 大腦嘅認知偏差 (Cognitive Biases)記憶錯亂 (Memory Errors) 造成。以下三個心理現象,最常被誤以為係「預知未來」

大腦嘅「預測功能」:點解我哋係一部預測機器

科學研究一直證實,所謂「超自然預知 (Precognition)」並冇可靠證據。但人類大腦本身卻具備一種極強嘅 預測功能 (Predictive Function)。從神經科學角度嚟睇,大腦其實係一部 Prediction Machine(預測機器),不停利用以往經驗去推測未來,再根據新收到嘅感官訊號作出修正。呢種能力解釋咗點解人類可以快速反應、避開危險,甚至提升學習同決策效率。

遲起身唔等於懶!夜貓同雲雀原來係基因決定

有啲人天生 早睡早起,朝早 6 點自然醒身,精神奕奕;但亦有人喺夜晚最有活力,凌晨兩三點先想瞓。呢種差異唔係單純習慣問題,而係與 Chronotype(睡眠型態) 有關。Chronotype 由基因 (Genetics)、年齡 (Age)、生活環境 (Environment) 一齊決定,直接影響你嘅睡眠時間、精神狀態同工作效率。

腦淋巴系統:大腦喺瞓覺時點樣「清垃圾」

我哋成日聽人講「瞓覺可以休息大腦」,但其實睡眠唔單止係休息,仲係大腦清理廢物嘅關鍵時刻。近年神經科學發現咗一個重要嘅系統:Glymphatic System(腦淋巴系統),負責喺瞓覺時清除代謝廢物,包括同 阿茲海默症 (Alzheimer’s disease) 有關嘅 β-amyloid(β-類澱粉蛋白)。
