初榨橄榄油与特级初榨橄榄油：有什么区别？
摘要
并非所有橄榄油都是一样的——“初榨”和”特级初榨”这两个术语指的是油的加工方式，而非其风味特征。Dr. Berg 详细解析了橄榄油和椰子油中精炼与未精炼油品的主要区别，并说明了哪种版本更值得购买。
核心要点
- 油品中的**“初榨”意味着未精炼**——通过冷压方式生产，不使用任何化学物质或高温处理
- 特级初榨橄榄油是过滤过程中最先提取的油，因此是最纯净、营养最丰富的选择
- 精炼橄榄油使用化学物质和高温生产，导致essential fatty acids、phytonutrients含量更少，且几乎没有气味
- 特级初榨橄榄油气味较浓郁，最适合用于沙拉，而非烹饪
- 初榨椰子油同样意味着未精炼——生产过程中不使用漂白剂、高温或化学物质
- “特级初榨”椰子油纯粹是一个营销噱头——初榨与特级初榨椰子油之间没有实质性区别
- 在选择这两种油时，初榨/特级初榨的区别对橄榄油而言很重要，但对椰子油而言并不重要
详细说明
橄榄油：精炼与未精炼
市场上的橄榄油主要分为两大类：
未精炼（初榨 / 特级初榨）
- 通过冷压生产——一种不使用热处理或化学物质的机械提取工艺
- 保留phytonutrients和essential fatty acids
- 具有明显、浓郁的香气和风味
- 特级初榨特指过滤过程中最先流出的油，是品质最高的提取物
精炼
- 使用化学物质和高温加工处理
- 产出质地轻盈、无气味的产品，营养价值大幅降低
- 植物营养素含量极少甚至为零，必需脂肪酸含量也更低
- 由于其中性风味和轻盈质地，部分人偏好用其烹饪
建议： 选择特级初榨橄榄油，尤其适合用于沙拉酱等冷食应用，可充分发挥其风味和营养价值。
椰子油：初榨与特级初榨
- 初榨椰子油 = 未精炼，不经高温、漂白剂或化学加工处理
- 特级初榨椰子油没有额外的标准或品质区分——仅仅是一个营销标签
- 与橄榄油不同，椰子油的初榨与特级初榨之间没有受监管的或有实质意义的区别
- 购买椰子油时，关键决策就是选择**初榨（未精炼）**版本，而非精炼版本

Virgin vs. Extra Virgin Olive Oil: What’s the Difference?
Summary
Not all olive oils are created equal — the terms “virgin” and “extra virgin” refer to how the oil is processed, not its flavor profile. Dr. Berg breaks down the key differences between refined and unrefined oils for both olive oil and coconut oil, and explains which versions are worth buying.
Key Takeaways
- “Virgin” in the context of oils means unrefined — produced through cold pressing with no chemicals or high heat
- Extra virgin olive oil is the first oil extracted during the filtration process, making it the purest and most nutrient-dense option
- Refined olive oil is produced using chemicals and high heat, resulting in fewer essential fatty acids, fewer phytonutrients, and virtually no odor
- Extra virgin olive oil has a stronger odor and is best used on salads rather than for cooking
- Virgin coconut oil also means unrefined — no bleach, high heat, or chemicals are used in its production
- “Extra virgin” coconut oil is purely a marketing term — there is no meaningful difference between virgin and extra virgin coconut oil
- When choosing between the two oil types, the virgin/extra virgin distinction matters for olive oil but not for coconut oil
Details
Olive Oil: Refined vs. Unrefined
There are two main categories of olive oil on the market:
Unrefined (Virgin / Extra Virgin)
- Produced through cold pressing — a mechanical process that extracts oil without heat or chemicals
- Retains phytonutrients and essential fatty acids
- Has a noticeable, stronger aroma and flavor
- Extra virgin is specifically the initial oil that comes out during filtration, making it the highest-quality extraction
Refined
- Processed using chemicals and high heat
- Results in a lighter, odorless product with significantly reduced nutritional value
- Contains fewer or no phytonutrients and fewer essential fatty acids
- Some people prefer it for cooking due to its neutral flavor and lighter texture
Recommendation: Choose extra virgin olive oil, particularly for cold applications like salad dressings where its flavor and nutrient profile can be fully appreciated.
Coconut Oil: Virgin vs. Extra Virgin
- Virgin coconut oil = unrefined, produced without high heat, bleach, or chemical processing
- Extra virgin coconut oil carries no additional standard or quality distinction — it is simply a marketing label
- Unlike olive oil, there is no regulated or meaningful difference between virgin and extra virgin coconut oil
- The key purchasing decision for coconut oil is simply choosing virgin (unrefined) over refined versions
