The Costa Rica guava, an atypical fruit and now an ice cream

08.01.2008
As its name suggests, the Costa Rica guava (Psidium friedrichsthalium Ndz.) originated in Costa Rica. It is a round or oval yellow fruit with a sweet/acid taste, somewhere between its "cousin" the guava and a passionfruit.

CIRAD imported this fruit tree into Réunion in 1993, as part of a plan to diversify agriculture in the humid highlands. To develop well in Réunion, the species has to be grown at heights of between 200 and 600 m above sea level, in which case it can produce up to 140 kg of fruit and may even double its yields after a devastating cyclone. The current production potential is estimated at around 15 tonnes a year.

Only two producers are currently growing Costa Rica guavas in Réunion, under the watchful eye of CIRAD, and until now, most of what they produce has been used by small-scale ice cream makers. However, the agrifood industry has also shown an interest in the past year or so. For instance, Glaces de Bourbon, a subsidiary of the CILAM (Compagnie laitière des Mascareignes) group, recently launched a new Costa Rica guava ice cream in supermarkets. The fruit has several good points: its distinctive flavour on the one hand, but above all its high vitamin C content (twelve times higher than oranges and three times higher than guavas).

The crop management sequence developed by CIRAD under a project aimed at diversifying agriculture in the highlands of Réunion limits the use of inputs and guarantees a "clean" crop. There had not previously been any technical references on this fruit, which was not grown commercially anywhere in the world: in its zone of origin, it was primarily grown in gardens and only occasionally in orchards.

If the product proves popular with consumers, it is likely to provide new outlets and enable the development of Costa Rica guava growing in the humid highlands. To satisfy future demand for the fruits, CIRAD is already storing plants, so as to plant new plots rapidly. These plots would serve both to provide new technical references and to supply the agrifood industry.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
