There are two different ways to leach acorns, and these include either a long soaking period or boiling them for an extended time, which has a quicker effect. Since these compounds are water-soluble, it means that we can easily remove them by soaking the acorns in water, which is known as ‘leaching’ ( 6). Remember how tannins are water-soluble polyphenols? Other varieties of acorns, such as red oak acorns, are still edible, but they require longer leaching times to remove the more considerable amount of tannins. Research in this area has demonstrated that white oak acorns contain much lower concentrations of tannins than other acorn varieties ( 5).įor reference, the following image shows what a white oak acorn looks like: Therefore, they require the least leaching time and have a less bitter taste. White oak acorns take the least time to mature and have the lowest tannin content among different acorns. While all acorns contain large amounts of tannins, the bitter types of the nut contain substantially higher concentrations, and they require longer leaching processes. On this note, there are several different varieties of acorns. However, before leaching the acorns, it is important to choose the right ones. PreparationĪcorns are not suitable to eat in their raw and unprepared state, so the first stage involves leaching. Key Point: Acorns are a type of edible nut, but they contain large amounts of tannins that need leaching prior to consumption. While acorns were part of traditional human diets, they are not a significant part of modern diets. Providing they have been adequately prepared to remove excess tannins, acorns have a mild nutty flavor. A large intake of tannins will also have an unpleasant taste, and excessive doses may potentially be harmful to the liver ( 1, 3, 4).įor this reason, acorns require appropriate preparation (such as leaching) before being consumed. One negative point is that tannins can act as an antinutrient, and studies suggest that they may inhibit the absorption of dietary iron.

These compounds may have both positive and negative impacts on human health ( 1, 2).

Tannins are a type of water-soluble polyphenol that is also found in tea and wine, and they have a bitter taste. However, unlike other nuts, acorns contain substantial concentrations of tannic acid (tannins). In a similar way to other popular nuts, acorns provide carbohydrate, fat, protein, and a wide range of essential nutrients. Acorns are the nuts of the oak tree, and they contain two seeds inside their hard outer shell. What are acorns?įirstly, acorns are a species of nut. This article provides a guide to edible acorns, their nutritional values, and their potential benefits and drawbacks. Interestingly, acorns are edible, providing that they are correctly prepared. Acorns grow in most parts of the world, but most of us don’t think of them as food.
