Why does raspberry have hair?


Raspberries are delicious fruits loved by many. They are small, red, and covered in tiny hairs that give them a distinctive texture. Have you ever wondered why raspberries have hair? In this article, we will explore the reasons behind this unique characteristic of raspberries.

The Anatomy of a Raspberry

Before diving into the reasons for raspberry hair, let’s first understand the anatomy of a raspberry. Raspberries belong to the Rosaceae family, and they are aggregate fruits composed of many small individual fruits called drupelets. These drupelets are arranged around a central hollow cavity known as the receptacle. The outer skin of a raspberry is covered in numerous fine hairs, which are known as trichomes.

Function of Raspberry Hair

The presence of hair on raspberries serves several purposes. Let’s explore some of the main functions:

1. Protection

The hair on raspberries acts as a protective barrier against external threats. It helps to reduce water loss from the fruit, preventing excessive dehydration. Additionally, the hair can deter pests and insects from feeding on the raspberry, protecting it from damage.

2. Moisture Retention

The hairs on raspberries help to trap moisture around the fruit, reducing evaporation and maintaining a higher humidity level. This moisture retention enhances the freshness and juiciness of the berries, making them more appealing to eat.

3. Temperature Regulation

The hair on raspberries also aids in temperature regulation. It acts as insulation, protecting the fruit from extreme temperatures. The hairs help to maintain a stable microclimate around the surface of the raspberry, safeguarding it from the adverse effects of heat or cold.

Types of Raspberry Hair

Raspberry hairs can vary in length, density, and texture. Let’s take a closer look at the different types of hair found on raspberries:

1. Glandular Trichomes

Glandular trichomes are short, sticky hairs found on the surface of raspberries. They secrete resinous substances that can provide additional protection against pests and pathogens. These hairs are often responsible for the characteristic aroma of raspberries.

2. Non-Glandular Trichomes

Non-glandular trichomes are longer, non-sticky hairs that cover the surface of raspberries. They play a significant role in reducing water loss and regulating temperature. These hairs give raspberries their distinctive fuzzy texture.

Raspberry hair itself does not provide any specific health benefits. However, raspberries are packed with essential nutrients, including vitamins, minerals, and antioxidants. Consuming raspberries, with or without hair, can contribute to a healthy diet.

4. Can I grow raspberries without hair?

No, you cannot grow raspberries without hair. Hair is an inherent characteristic of raspberries and is determined by their genetic makeup. If you come across raspberries without hair, they may be a different variety or have undergone genetic modifications.

5. Are there any other fruits with hair?

Yes, there are other fruits that have hair-like structures on their surface. Examples include kiwi fruit, peach, and tomato, among others. These hairs serve similar functions to those found on raspberries.

6. Do raspberries lose their hair when cooked?

Yes, raspberries tend to lose their hair when cooked or heated. The heat breaks down the structure of the hair, resulting in a smoother texture. This is why raspberry-based sauces and jams often do not have visible hairs.

7. Can I use raspberry hair for any other purposes?

Raspberry hair has been used in traditional medicine and herbal remedies. It is believed to have anti-inflammatory and soothing properties. However, more research is needed to validate these claims.


Raspberry hair serves as a protective mechanism for the fruit, providing benefits such as protection against external threats, moisture retention, and temperature regulation. The different types of hair found on raspberries contribute to their unique characteristics and texture. Whether you choose to eat raspberries with or without hair, they remain a delicious and nutritious fruit that can be enjoyed in various ways.
