山梨酸 (E200): 食品防腐劑

Sorbic acid is a naturally occurring organic compound that has been shown to be a potent inhibitor of mold, yeast and fungi and is commonly used as a food preservative.

  • The chemical formula is C6H8O2
  • International Union of Pure and Applied Chemistry Name: (2E,4E)-Hexa-2,4-dienoic acid
  • CAS 110-44-1
  • E 200

describe

Sorbic acid is white powder or crystal. The taste is slightly sour, slightly astringent, and has a faint odor.

food preservatives

Sorbic acid and its salts, such as potassium sorbate and calcium sorbate, are widely used as preservatives in food and beverage products to extend shelf life by inhibiting the growth of mold, yeast and fungi. It can effectively prevent the decay of various acidic and low pH foods .

Sorbic acid is commonly found in food, animal feed, pharmaceuticals and cosmetics. It is frequently used for the preservation of wine, cheese, baked goods, fresh produce, and refrigerated meats and shellfish.

Its natural antibiotic properties make it effective against Clostridium botulinum and prevents botulism poisoning.

It also has antifungal properties and is suitable for use in canned foods such as pickles, plums, black cherries, figs and salads.

antibacterial properties

The function of sorbic acid is to destroy the cell membrane of microorganisms and prevent their growth and proliferation. It is particularly effective against mold and yeast, making it a popular choice for preserving acidic foods where other preservatives may not be as effective.

natural source

Sorbic acid occurs naturally in some fruits, such as rowan berries.

Sorbic acid and potassium sorbate are used in many foods that claim to be "natural." Although sorbates occur naturally in some fruits, they are manufactured synthetically for commercial use, so describing them as "natural" is misleading. They are one of five groups of preservatives to avoid listed on the RPA elimination diet, along with benzoates, sulfites, nitrates/nitrites and propionates.

Sorbic acid is the preferred preservative compared to nitrates, which can form carcinogenic by-products.

Safety Precautions

When used in accordance with good manufacturing practices, sorbic acid is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). Sorbic acid is used as a chemical preservative in foods for human consumption and is generally considered safe if used in accordance with good manufacturing practices.

Sorbic acid is used as a chemical preservative in animal medicines, feeds and related products and is generally considered safe when used in accordance with good manufacturing or husbandry practices.

Some people may have a mild allergic reaction or sensitivity to sorbic acid.

Applying 150 mg of sorbic acid to human skin for 1 hour can cause severe irritation.

Sorbates have been linked to asthma, eczema, contact dermatitis, eye irritation, nasal irritation, and burning mouth syndrome, as well as various food intolerance reactions, including irritable bowel symptoms and behavioral problems in children.

Allergic contact dermatitis caused by sorbic acid is most commonly reported after use of topical medications containing sorbic acid preservatives (e.g., corticosteroid creams). People with eczema should avoid using sorbic acid in cosmetics because of the potential for irritation.

Sorbic acid can also cause stinging and a non-immune contact urticarial reaction.

regulatory approval

Sorbic acid and its salts are approved for use as food additives by regulatory agencies around the world, including the US FDA and the EU European Food Safety Authority (EFSA). Because it has nothing to do with cancer or other major health problems.

Maximum use levels and labeling requirements may vary depending on the specific food application and regulatory jurisdiction.

Storage and handling

Sorbic acid is usually available as white crystalline powder or granules. Should be stored in a cool, dry place away from direct sunlight and moisture to prevent degradation. Proper safety measures should be taken when handling sorbic acid, including wearing protective gear such as gloves and goggles.

generalize

Sorbic acid is a widely used and effective food preservative that helps maintain the quality and safety of a variety of foods. When used responsibly and in compliance with regulatory guidelines, it plays an important role in extending the shelf life of perishable foods and reducing food waste.

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

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。

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)。

睡眠不足與情緒健康:焦慮與抑鬱的隱藏推手

好多香港人、台灣人甚至全球都市人,都認為「捱夜」只係令身體攰啲,但其實 睡眠不足對情緒健康影響極深。研究顯示,缺乏睡眠唔單止會令人心情差,仲係 焦慮 (Anxiety)抑鬱 (Depression) 嘅高危因素。對於 嗜睡症 (Narcolepsy) 患者,呢種風險更高,因為佢哋天生嘅睡眠結構失調,令情緒波動更加嚴重。

為何過度疲勞會令你進入「恐懼模式 」?

好多時候,大家經歷過捱夜、返工返學壓力大,會覺得整個人進入咗一種「生存模式 (Survival Mode)」:神經繃緊、疑神疑鬼、甚至有啲恐懼感。呢種情況唔只係心理作用,其實背後有大腦與荷爾蒙嘅科學解釋。
