Improving the organoleptic qualities of fruits and vegetables is the main objective of agricultural producers and marketers, in order to give added value to the final product that results in a better price.

The agricultural auxiliary industry sector works to provide the necessary advances in plant breeding, with research and development of new varieties resistant to pests and diseases, which adapt better to the new climatic conditions we are suffering, higher temperatures and lack of irrigation water to cover the needs of crops. In this sense, from the plant nutrition and agricultural biostimulants sector we work on the formulation of products that are capable of increasing ºBrix in fruits, improving color, firmness and long shelf life.

Which JISA products improve the color and flavor of fruits?

In this context, JISA is advancing in the development of special agronutrients and agricultural biostimulants, which help farmers improve the organoleptic qualities of their cultivated fruits and vegetables.

At the level of plant nutrition and after numerous scientific investigations we know that, if we want to improve color, we can generalize and say that, nitrogen (N), in addition to favoring the synthesis of chlorophyll, its excess can cause a dark green color and bitter taste; phosphorus (P) promotes the formation of anthocyanins, pigments responsible for red, blue and purple colors in fruits; potassium (K) influences the intensity of color and its deficiency can cause a decrease in tones.

Regarding flavor, for example, nitrogen also balances flavor and an excess can cause a dominant acid taste; phosphorus increases the sugar content and boron (B) helps mobilize them, which intensifies the sweet taste; potassium regulates the balance between sweet and bitter and its deficiency can cause an excessive bitter taste; Calcium (Ca) promotes the development of characteristic flavours in some species; and magnesium (Mg) is involved in the perception of sweet taste.

And to continue with a final example, in the case of aromas, phosphorus stimulates the synthesis of volatile compounds responsible for the characteristic aroma; potassium influences the intensity and persistence of the aroma; and sulphur (S) is essential for the formation of aromatic compounds in some species.

Among the JISA catalogue of special agronutrients and as examples, Jisafol® fattening as a potassium solution with neutral pH, Top-K® is a formulation based on Potassium with rapid assimilation and osmoprotective effect, Jisaquel® potasio as a corrector with a high potassium content with EDTA and Jisafol® kalium as a foliar fertiliser with a high potassium content also with EDTA. Not forgetting Nutrijisa® boro, as a corrector based on boron ethanolamine.

Fruit and vegetable fairs

The interest in organoleptic qualities worldwide.

Since the beginning of this century, we have been living in a totally globalized world, in which, for example, the fruit and vegetable marketing sector allows the availability of these products 365 days a year on supermarket shelves.

To this end, one of the premises on which it has evolved, in addition to logistics, is the development of coordinated agricultural production in all those countries that, as a whole, take into account the factor of off-season production.

In this sense, a final product with a good appearance and that is capable of withstanding long transport journeys, even overseas, has been sought, and in some cases “some levels of organoleptic qualities have been left aside or sacrificed.”

But in recent years we have found ourselves facing a new scenario. Part of society is changing its eating habits and is willing to pay a little more for fruits and vegetables that guarantee, firstly, adequate nutrition and secondly, enjoy the pleasure of eating a fruit or vegetable with flavour and that forms part of dishes that are as exquisite as they are healthy.

Given this interest in organoleptic qualities worldwide in fruits and vegetables, the entire value chain, from research to the point of sale, including plant material companies, agronutrients, growers, etc. are “focusing” on meeting this extra demand of the consumer.

Transfer of innovation for advances in the agricultural sector.

In this context, international fairs related to agriculture are an important showcase for the transfer of advances in the agricultural sector. These fairs are a key meeting point for those companies that belong to different areas of the auxiliary industry, fertilizers, seeds, agricultural technology, etc., and of course, companies that produce and/or market fruits and vegetables.

These events take place in the main agricultural markets and on all continents, being a strategic space for the transfer of innovation for advances in the agricultural sector… and among them those that affect and intervene in organoleptic qualities.

That is why the JISA teams and network are present at the most important international fairs in the sector, working on the transfer of their products as a result of their R&D&I, in which, in addition to contributing to greater crop productivity, they influence the improvement of their organoleptic qualities.

An example of these international agricultural fairs are Fruit Logistica (Berlin, Germany); Fruit attraction (Madrid, Spain); Macfrut (Rimini, Italy); Growtech (Antalya, Turkey), Hortitec (Holambra, Brazil), Asia Fruit Logistica (Hong Kong), Expo Agro Alimentaria (Guanajato, Mexico), Sahara Expo (Cairo, Egypt) or Siam Meknes (Meknes, Morocco).
