Results of the first orange and grapefruit maturity tests for the 2022-2023 season, using only regular bloom fruit, are listed below. Sample groves and trees remain relatively constant from season to season. Fruit was picked from trees throughout the citrus growing region on August 29-30, 2022. Each sample was weighed, juiced, and tested by the Florida Agricultural Statistics Service (FASS) on August 31, 2022, and September 1, 2022.

Starting in mid-July 2022, GEA and Israeli start-up Better Juice will conduct product tests on behalf of beverage manufacturers looking to lower the sugar content in drinks. To provide the service, the new GEA Better Juice Sugar Converter Skid, which the industrial systems supplier developed based on the Better Juice process, has been installed at the GEA Test Center in Ahaus, Germany. With this innovative solution for the juice industry, GEA is raising the profile of the Ahaus facility as a key hub for piloting aseptic processing and filling of sensitive foods and beverages.

Test Center provides solutions for unique product requirements

“We can now collaborate with our customers at the Test Center to strike the ideal balance between a sweet note and reduced sugar content,” says Gali Yarom, co-founder and joint CEO of Better Juice. To that end, the microbiologists from Better Juice will join forces with GEA’s specialist engineers to support and guide companies in running trials. The GEA Test Center at Ahaus will provide laboratory services dedicated to testing all important analytical parameters.

“It’s often necessary to initially demystify innovative solutions like the Better Juice process. That’s why it’s all the more important to make the case for the technology with manufacturers in person,” says Sascha Wesely who leads the Non-Alcoholic Beverages business at GEA. “The Ahaus trials help us optimize process efficiency right from the outset. By running scalable tests under real-life conditions, we significantly cut the time to market.”

A scalable, enzymatic solution to removing up to 80 percent of sugar from fresh juices

Thanks to a patented enzymatic process, this is the world’s first solution that naturally reduces the sugar content of fruit drinks by up to 80 percent, without affecting its nutritional value or authentic taste. The juice flows continuously through a bioreactor containing GMO-free, immobilized microorganisms which convert simple sugars into prebiotic, non-digestible molecules that benefit the intestinal flora. As a result, the GEA Better Juice Sugar Converter Skid succeeds in removing up to 80 percent of the sugar in natural fruit juices, concentrates as well as fruit-based mixtures, such as purees. At the end of 2021, the partners won their first commercial order from a company in the U.S. where, once integrated into production, the system will create juices with much less sugar.

Now revised and updated

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. 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.
