Both if you work in the purchasing or procurement department of an industrial food company and if you work in the quality department, the content of this article will be of great interest to you. In this text you will find everything you need to know about the different peanut types and the main aspects you need to keep in mind during its purchasing process.
Peanut stands out due to its nutritional value. Specifically, peanut kernels contain approximately 50% of fatty acids – mainly monounsaturated and polyunsaturated such as oleic and linoleic acid – and proteins (25%). On the other hand, they also stand out due to their high fibre content, vitamin B6, vitamin E (α-tocopherol); as well as minerals: magnesium, potassium, phosphorous, copper and manganese. Lastly, they are a source of group B proteins and vitamins, such as pantothenic acid1.
Thanks to their high content of vegetable protein and fat (especially monounsaturated), peanuts are a versatile ingredient that can take different forms. It is the main ingredient of peanut butter and it can be transformed into oils, extracts, they can be chopped, halved, diced and turned into peanut flour or pastes1.

In addition, the nutritional and sensory properties of peanuts make them a unique, differentiating ingredient in a myriad of food products. For this reason, at Itac Professional, the B2B brand of Importaco Group for the food industry, we offer them in a wide range of forms that boost flavours and create a unique texture in products of industries such as chocolate, confectionery and dressings, among others.
There are different varieties and types of peanuts, each with different characteristics, uses and growing regions.
Runner High – Oleic Peanuts
The development of high oleic peanut has been an important innovation in the peanut industry. The fat content of this peanut includes 75% of oleic acid and 5% of linoleic acid, which implies an oleic/linoleic essential fatty acid ratio that is significantly higher than that of conventional peanut, exceeding 15:12. At Itac Professional we sell High Oleic Runner peanut from Argentina. It is suitable for use in food and the snack industry.

After reviewing the different peanut types, now it is time to delve into the purchasing process. As with all foods sold in the European Union, peanuts must comply with a series of highly stringent regulations and requirements that guarantee their safety. There are, for example, a series of limits for pesticide residues, mycotoxins and contaminants that are considered to be harmful. This legislation also includes imported products.
These are the most important factors that must be considered when importing and buying peanuts for consumption within the European Union:
In order to guarantee the maximum possible safety for the peanuts, producers and processors apply all kinds of good practices strategies all the way from the field, through manufacturing to the storage of these products. Below we highlight a few details regarding these practices.
Peanuts are manufactured by taking into account the following quality criteria.
At a general level:
It must be certified that they are safe and suitable for processing for human consumption.
They must be free from undesired flavours and odours, as well as insects and live mites.
At a specific level, it is important to take into account the following quality criteria, among others:
When talking about peanuts and peanut types, we must keep in mind the possible chemical or microbiological contaminants that they might contain, including: total plate count, the presence of yeast and mould, Enterobacteriaceae, Coliforms, E. coli and the negative Salmonella value.
It is essential to make sure that the peanut manufacturers are making the necessary controls to detect salmonella and E. Coli, two of the most frequently found bacteria in processed foods that often cause public health problems.
At Itac Professional we perform microbiological tests that include:

The presence of mycotoxins and, in particular, aflatoxins – chemical substances produced by toxicogenic strains of mould such as Aspergillus flavus and Aspergillus – is one of the main reasons why a specific peanut batch might be declared to be unfit for consumption in the European Union.
The maximum allowed levels of aflatoxins in peanuts varies depending on each region of origin, and these levels often change in the legislation, which is why it is significantly important for your supplier to be familiar with these regulations and offer you as much support as possible in this regard.

Most European buyers require a certification recognised by the Global Food Safety Initiative (GFSI). For peanuts, the most popular certificates are:
The European Union establishes maximum residue limits (MRL) for pesticides present in food products. Products that have a higher concentration of pesticide residue than allowed are withdrawn from the European market. It is uncommon to find high levels of pesticides in peanuts, since the shell – where residues can accumulate – is removed before consumption.
The European Union periodically publishes a list of pesticides that are authorised for use in the European Union. This list is updated regularly. At Importaco Group we train and audit our farmers and producers to guarantee that these products are correctly applied and ensure the lowest environmental impact.
Sensory attributes are broken down into:
– Visual characteristics: Related to the aspect of the product. Colour, size, colour & size uniformity, etc.
– Organoleptic characteristics: Related to the odour and flavour of the product. Saltiness, presence of atypical flavours or odours, etc.
– Textural characteristics: Related to the texture of the product. Firmness, crunchiness, etc.
At Itac Professional we perform the appropriate sensory analyses to guarantee that our peanuts have the best quality before they are sold to industrial producers.
Regarding the physical parameters, it is important to take into account the following aspects:
1 Typical pod defects that must be examined
2 Typical kernel defects that must be examined
3 Peanuts different from the intended type
This refers to the mixture or presence of other varieties.
At Itac Professional we are nut suppliers for various segments of the food industry. Our specialisation as peanut suppliers has allowed us to implement a total control system over this product’s traceability – from the field, all the way to the final delivery.
At Importaco we are thoroughly convinced that it is only through specialisation that an outstanding quality, food safety and sustainability can be achieved. For this reason, we have a factory specialised in peanut processing – a production plant where we work with the best staff and the safest, most innovative and advanced technology and working processes.
