Walnuts are taking a leading role in the food industry – especially in the field of new product developments. The versatility of this nut makes it ideal to be part of a myriad of novel foods. In this article you will find information about the benefits of this ingredient and we will delve deeper into the uses of walnut in different food industry sectors.
In the food industry, walnuts are used in dairy alternatives, snack bars, appetizers, cereals, energy bars, baked goods and even as walnut butters.
Walnuts are a healthy and nutritious food, with a great capacity to attract a type of consumer that is increasingly less willing to consume products that contain artificial products that are harmful to the body.
Nowadays, the main trend in the food industry is looking for natural, healthier alternatives with a preference for functional, transparent foods with high nutritional value, such as those that contain vegetable proteins. These new needs can be fully satisfied by walnuts thanks to their characteristics and natural properties.
The nutritional value of walnuts makes them very appealing to manufacturers. More specifically, they offer a high content of omega-3 ALA, which is very beneficial to reduce the risk of heart disease.
The most appealing features of walnuts as ingredients in new product developments could be summed up as: their vegetable and completely natural origin, their high nutritional value and their versatility. And to this list we must also add their magnificent flavour.
What are the nutritional benefits of walnuts as an industrial ingredient?
According to the U.S. Department of Agriculture, Agricultural Research Service, walnuts have a high content of polyunsaturated fats, fibre, thiamine, vitamin B6 and minerals such as phosphorous, magnesium, zinc, copper and manganese. Moreover, walnuts are a source of iron and potassium.
In addition, walnuts have other huge benefits for the food industry:
- They are used to make walnut milk, a perfect substitute for animal-based milk. Here, manufacturers can promote the omega-3 fatty acid content of their products.

Uses of walnut: Analysis in new product developments per industry
Walnuts have gained a position of importance in the field of new product launches given that the properties of this nut make it ideal to be included in the formulation of a myriad of new products. In addition, walnuts are a natural, versatile, healthy products with a pleasant flavour – properties that are completely in line with the needs and expectations of new consumers.
Below we will take a look at the innovations in the application and uses of walnut across different segments of the food industry.
Baked goods industry
For a number of years now, walnuts have been added as ingredients in sweets, cookies and brownies.
However, in recent times, the application of walnuts in bakery has transcended the boundaries of sweets, becoming increasingly common in breads, pan loaves and bars, with consumers demanding the inclusion of ingredients that feel more familiar or transparent to them in these products. Their subtle nut flavour, in combination with their texture – not too hard, not too soft –, make walnuts an ideal ingredient when looking for formulations that are more transparent and do not compromise the flavour or pleasure during consumption.
Walnuts support the clean label trend in the baked goods industry – products that have a limited list of natural ingredients, forgoing the use of artificial and superfluous additives. Walnuts are a perfect fit for this category, and they can be found as a main ingredient in new cake or cookie concepts manufactured with natural, sugar-free ingredients, for example.

Bars are currently trending among consumers, a fact that is driving innovation among the manufacturers of this product. Here we are seeing the emergence of an increasing number of types and formats, characterised by a great variety of ingredients, flavours and textures.
In order to be accepted by most consumers, the bars need to be healthy, nutritious and be made out of few ingredients – preferably of vegetable origin. In this regard, walnut bars are gaining an increasing competitive advantage due to their ability to offer a pleasant flavour and texture and an excellent nutritional value packed in a single ingredient.
Among the main claims made by these products related to walnuts, we can find functional components such as omega-3 fatty acids or the concept of nut-based nutrition bars filled with good fats. Bars packed with nuts can quell hunger and offer nutrition with clean labels and whole ingredients.
Walnuts and chocolate go well with each other when it comes to flavour, texture and consistency. One of the concepts that are most valued by consumers is the fact that chewing walnuts does not require much pressure, which offers a pleasant and fluid experience when enjoying a piece of chocolate with walnuts.
Many new types of chocolates include walnuts in their formulation due to their wonderful properties, which include an excellent flavour, ease of preservation, great consistency, nutritional value and the ability to use them in different aroma and texture profiles.

Breakfast cereals are among the food categories that are seeing the most significant evolution in the latest times, experiencing diverse and important innovations in relation to the formulation of ingredients, the combination of flavours and even in relation to packaging.
Traditionally, the cereals category has been divided into products filled with sugar for children and healthier options for adults. These boundaries are getting blurred in favour of simpler labels and eliminating artificial ingredients.
For example, nowadays it is not unusual to see whole-grain cereals for children and functional cereals for adults.
Walnuts are perfectly suited for all of these changes, trends and new ways to consume cereals. For example, their omega-3-ALA and fibre content makes them an ideal ingredient to obtain a number of health benefits, including keeping cholesterol and the blood pressure in check, thereby reducing the chances of suffering from heart disease.
On the other hand, cereals ready-to-eat that contain walnuts provide an energy boost thanks to their high protein content. This allows them to fulfil one of today’s main trends for this type of food: eating them at any time of day and complement, or even replace, a meal.
One of the main novelties of the new cereal formats is the mixture of flavours: salty, sweet, spicy – a goal that walnuts can help with, since they go perfectly with a wide range of foods and ingredients.
Though these have traditionally been associated with high-calorie unhealthy products designed to have a bite to eat between meals, nowadays there are certain kinds of snacks that have completely overturned this concept.
New snack trends are based on the introduction and combination of new flavours that are sometimes original and exotic, such as wasabi and other ethnic flavours, bitter (chocolate or pure) or sour.
The purpose of today’s snacks is not only to have a bite between meals, but also to replace some meals, meaning that their energy content and nutritional value must be high.
Walnuts are a prime ingredient for this new generation of snacks, since they are a complete, high-calorie food with a great nutritional value and highly flexible when it comes to combining them with any kind of ingredient and flavour. In this regard, salted walnuts have become highly popular among consumers due to their texture and ability to complement sweet, salty and spicy profiles.
In summary, walnuts make an excellent ingredient for the preparation of foods, being increasingly demanded due to their multiple uses and nutritional benefits, being a source of Omega-3 alpha-linoleic (fatty) acid (ALA) and other nutrients that are beneficial to consumers.
