French fries 是纯素的吗？

取决于品牌

视情况而定——土豆是纯素的，但油炸脂肪、裹粉和炸锅则不总是。

也列为：薯片, 薯条, 炸薯条

关键事实

裁定: 取决于品牌
类别: 餐馆食物
也列为: 薯片, 薯条, 炸薯条
最佳替代品: 在家用烤箱炸薯条

为什么

用植物油炸的普通土豆是纯素的。问题在于使用牛油（一些连锁店和传统炸鱼薯条店仍在使用）油炸，预炸裹粉中的“天然牛肉风味”，调味料中的牛奶或乳清，以及与炸鱼或炸鸡共享的炸锅。

标签上要检查什么

用它来替代

在家用烤箱炸薯条使用菜籽油或葵花籽油油炸的连锁店空气炸锅炸的撒有辣椒粉和盐的土豆

What is actually in it

Fries pass through two fat baths. At the factory the cut potato is blanched and par-fried, which sets the crust and lets it freeze without going grey; at the restaurant it is finished in the fryer. Either stage can introduce animal products. Historically most large chains par-fried and finished in beef tallow because saturated animal fat gives a firmer crust and a distinctive flavour; the switch to vegetable oil in 1990 left some brands adding a flavouring back in to compensate, which is where the notorious 'natural beef flavour' with hydrolysed milk and wheat comes from. Coatings are the second trap: many frozen fries are dusted with a dextrin or rice-flour batter for crispness, and a minority include whey or lactose for browning. Third is cross-contact — one fryer shared with breaded fish, chicken or mozzarella sticks. None of those are visible on a menu, so the reliable move is to check the chain's published allergen and ingredient sheet for the specific country you are in, since recipes are formulated per market.

常见问题

麦当劳薯条是纯素的吗？

这取决于国家。在美国，预炸使用了含有牛奶衍生物的天然牛肉风味；在英国、爱尔兰和欧洲大部分地区，薯条被认证为纯素，并在专用炸锅中烹制。

那炸鱼薯条店的薯条呢？

询问炸锅使用什么油。在英格兰北部和比利时部分地区，牛脂仍很常见。

Are frozen supermarket fries vegan?

Usually yes if the ingredients read potato, vegetable oil, dextrose and a raising agent. Check for whey, lactose or 'flavouring' with no origin given.

Is a shared fryer a dealbreaker?

That is a personal line. It is not an ingredient, but trace transfer from battered fish is real; many vegans accept it, many do not.

What about sweet potato fries?

Same rules plus one more: the crisp coating on frozen sweet potato fries more often contains milk-derived browning agents.
