One of the most common tests conducted in the juice manufacturing industry is the measurement of soluble solids by refractometry. It is not only used for the assessment of a quality parameter but it is also commercially important where used in yield assessment. The IFU method number 8 describes this method. The principle is that the dry soluble solids content of a sample is estimated from its refractive index, with reference to the refractive index of a pure sugar solution. The refractive index is proportional to the solution concentration (following the theory of Lorentz and Lorenz). In fruit juices the refractive index is therefore dependent upon sugar concentration and also upon the concentration of other soluble materials (organic acids, minerals, amino acids etc.).

The method has been recently revised to include a weight per litre table. The correction of soluble solids for malic/tartaric acid and salt is still under discussion but will be available in the near future. The method can be obtained via the IFU website


Anuga FoodTec and the IFU have agreed on an extensive partnership. The agreement includes a package of measures encompassing both communicative aspects as well as an increased presence at Anuga FoodTec 2018. The aim of the cooperation is to offer representatives from the fruit juice industry a platform and to create added value at the leading supplier trade fair for the food and beverage industry in Cologne.

One of the aims of the partnership is the inclusion of a technical workshop by the IFU at Anuga FoodTec 2018 branded “For the Juice Industry. From the Industry Experts.” The technical workshop will offer a forum for up to 20 presentations by leading companies, laboratories and research institutes. Senior technical, quality and R&D managers and employees will get the chance to work with each other and exchange ideas at the workshop . Workshop themes will include production, microbiology, quality and CSR.

As part of the deal the IFU will be represented with an exhibition stand at Anuga FoodTec in Cologne and Anuga FoodTec will also be present at selected events of the IFU. In terms of communications, the partners will support each other via the respective channels in the form of a mutual content exchange as well as carrying out sponsoring campaigns of individual formats.

Anuga FoodTec (20th to 23rd March 2018) is one the world’s leading trade fairs for the food and beverage industry. The cooperation with the IFU particularly builds a further bridge to the beverage industry.




The IFU and the SGF have been invited to participate in the Japan Fruit Juice Associations (JFJA) festivities to celebrate 60 years of the fruit juice industry in Japan. The SGF IFU Roadshow will be included in their seminar as follows:

Date: September 15th, 2017 from 10:00 to 17:00. Registration begins at 09:30. Lunch Break 11:45 – 12:40. The venue for the conference is the Yakult Hall (Yakult Head Office building). Address: 1-1-19 Higashi-Shinbashi, Nimato-Ku, 105-8660 Tokyo. The venue for the social gathering will be the Beer Hall in Ginza, Tokyo. Participation is possible by invitation and details are available from who is liaising with the JFJA.


The SGF IFU Asia Roadshow is included in the Arab Beverages Conference & Exhibition ABCE 2017 on October 29th and 30th in Dubai, UAE. Registration is free of charge and more information can be found at
