如何看待阿斯巴甜或可致癌的影響?
本文來自格隆匯專欄:中信證券研究,作者:盛夏 王聰
中信證券認為,出於安全性和成本的考慮,預計下游廠商會加速三氯蔗糖等更安全的甜味劑對阿斯巴甜的替代。此外,隨着人們對於甜味劑的來源及安全問題關注度的不斷加強,對天然甜味劑需求預計還將高速增長。從投資維度,建議關注兩條主線,一是三氯蔗糖加速對阿斯巴甜的替代;二是關注天然甜味劑。
事件:
根據路透社報道,世衞組織下屬國際癌症機構(IARC)或在7月將阿斯巴甜甜味劑首次列為“可能對人類致癌的物質”,目前阿斯巴甜主要應用於健怡可口可樂、零度可口可樂、Snapple飲料及瑪氏Extra口香糖等飲料及零食中。
IARC並非食品監管機構,其研究只表明一種可能性。
該機構的主要任務是進行和促進對癌症病因的研究,其將致癌物劃分為以下幾個等級:1類和2A類致癌物(要儘量避免接觸),2B類致癌物(無需過度緊張,只有大量接觸和長時間接觸可能會增加致癌風險),3級和4級致癌物(一般不用擔心)。根據路透社的報道,目前根據已有消息阿斯巴甜或將被劃分為2A類或2B類致癌物。目前,紅肉、熱飲均屬於2A類致癌物;“手機輻射”屬於2B類致癌物。
若引發消費者廣泛擔憂,或加速對阿斯巴甜的替代。
飲料廠商應用人工合成甜味劑的本質是在健康的前提下,低成本的代替糖的“甜度”。阿斯巴甜屬於最常見的人工合成高倍甜味劑之一,甜度約為蔗糖的200倍,目前全球市場約3萬噸左右,市場規模約30億元。三氯蔗糖作為新一代高倍甜味劑,安全性更好、甜度更高(600倍甜),且甜度曲線與安塞蜜較為接近。我們認為,出於安全性和成本的考慮,預計下游廠商會加速三氯蔗糖等更安全的甜味劑對阿斯巴甜的替代。
消費者或加大對人工合成甜味劑的擔憂。
僅從甜度替代的角度,天然甜味劑不具備成本優勢,但是由於其“天然”的屬性以及具備一定的“功能性”,因此更受消費者的認可。根據英敏特數據,2010-2020年間,天然甜味劑在代糖產品的應用的佔比由8%迅速增長至29%,隨着人們對於甜味劑的來源及安全問題關注度的不斷加強,對天然甜味劑需求預計還將高速增長。
風險因素:
食品安全風險;行業監管風險;產品替代的風險。
投資策略。
從投資維度建議關注兩條主線,一是三氯蔗糖加速對阿斯巴甜的替代;二是關注天然甜味劑。
