  • The Interprofessional of Lemon and Grapefruit of Spain has also requested “the application of ethylene in citrus” in organic production “because unlike what happens in other fruits or vegetables, does not induce ripening but only to change the color of the skin”.
  • Both comments have been submitted as part of the consultation period that the European Commission has opened on the draft regulation authorizing products and substances to be used in organic production.

The Interprofessional Association of Lemon and Grapefruit of Spain (AILIMPO) has submitted a proposal to the European Union for the food industry BIO products to replace the use of citric acid (E-330) by organic lemon juice “for being a totally effective and natural alternative“. The proposal has been presented by AILIMPO in the framework of the consultation period that the European Commission has opened on the Draft Implementing Regulation authorizing certain products and substances for use in organic production and establishing their lists.

“We have requested the elimination of the authorization of this substance (citric acid E-330) as a preservative in food additives because it is perfectly substitutable in the processes by organic lemon juice whose main component is natural citric acid, whose production in Europe fully guarantees its availability “, said from AILIMPO, while recalling that Spain is a community leader in production and processing of lemon.

AILIMPO, in favor of using ethylene in organic citrus

In addition, AILIMPO has also submitted an observation to be able to use ethylene. The draft regulation establishes an important limitation for its use in organic citrus. This substance is used so that, once the internal maturity of the fruit is reached, the skin changes its green color to the characteristic color of the species and variety. This process is called degreening.

Since its use is restricted to organic citrus as part of a fruit fly prevention strategy, it could not be used for degreening. However, “the application of ethylene in citrus, unlike what happens in other fruits or vegetables, does not induce ripening but only to change the color of the skin,” clarified from AILIMPO whose position is not to limit the use of ethylene in organic citrus.

“AILIMPO has an important commitment to sustainability as is being made visible through the Welcome to the Lemon Age campaign,” they remind. The organic production of lemon and grapefruit has great relevance in its activity, hence the involvement of interprofessional in defending the interests of this sector. Therefore, AILIMPO has already moved this position also to the European organization FRESHFEL EUROPE, the Spanish Ministry of Agriculture, Fisheries and Food, the citrus Autonomous Communities, and the Councils of Organic Agriculture involved in order that their contributions to this draft implementing regulation take into account the considerations of the sector.

Below are the links to AILIMPO’s contributions to the public consultation of the Regulation.



AILIMPO is a national interprofessional, based in Murcia, officially recognized by the Ministry of Agriculture, Fisheries and Food of Spain and the European Commission, which represents the economic interests of producers, cooperatives, exporters and processors of lemon and grapefruit in Spain, a sector in which Spain is a world leader in fresh exports and ranks second in the ranking of processing countries, with an annual turnover of 700 million euros, generating 20,000 direct jobs and a turnover in ancillary industries of more than 250 million euros.

Determination of Acetic Acid (enzymatic method)

This method has been revised and has been loaded onto the IFU website. It now includes precision data.

General information

This method serves to determine the acetic acid content of a fruit and vegetable juices & purees. Provided that it meets characteristic performance, this enzymatic method can also be carried out using an automatic analyser.


Acetic acid (acetate) is converted in the presence of the enzyme acetyl-CoA synthetase (ACS) with adenosine-5′-triphosphate (ATP) and coenzyme A (CoA) to acetyl-CoA.

Acetyl-CoA reacts with oxaloacetate to citrate in the presence of citrate synthase (CS).

The oxaloacetate required for reaction (2) is formed from malate and nicotinamideadenine dinucleotide (NAD) in the presence of malate dehydrogenase (MDH) (3). In this reaction NAD is reduced to NADH.

The determination is based on the formation of NADH which is measured by the increase in absorbance at 340, 334 or 365 nm. Since a preceding indicator reaction is used, the amount of NADH formed is not linearly proportional to the acetic acid concentration.

Cargill has the intention to invest $150 million to construct an HM pectin production facility in South America. HM pectin is a versatile, citrus fruit-based texturizer used for jams, beverages/juices, acid dairy drinks and confectionery.

Bruce McGoogan, strategy and innovation leader for Cargill starches, sweeteners and texturizers business said, “The pectin market has seen a strong growth for several years, primarily driven by the acid dairy drink market, as well as the growing global consumer demand for label-friendly ingredients. HM pectin plays a significant role in delivering on both trends—as it is a plant-based texturizer designed for acid dairy drinks as well as for jams, beverages and confectionery products. The intention to invest in a plant in Brazil, which has an abundant citrus fruit supply, allows Cargill to deliver the pectin our customers need and consumers demand.”

The intended project is part of a comprehensive plan to strengthen Cargill’s full pectin footprint, including improvements to its existing three plants in Europe (Germany, France and Italy) and adding a new plant in Brazil to take advantage of local resources.

“Adding an industry-leading pectin asset in Brazil will complement Cargill’s existing European network and create the capacity to serve our customers around the globe with premium pectin ingredients,” said Laerte Moraes, managing director of Cargill’s starches, sweeteners and texturizers business in South America. “The intended investments also illustrate Cargill’s commitment to its employees and the economies in both Europe and Brazil through job growth and financial contributions. The intention is to start construction early 2019.”
