Truffle hunting in Istria began in the mid 20th century when the first written records were recorded about it. Initially, the local population started collecting truffles as it was actually a great addition to their home budget. At this time, the final destination of the truffles were mainly the foreign markets. More recently, the truffle hunters realized that the value can be increased if the product was placed on the domestic market. Thus, in the 1990s, truffle promotion was promoted as a valued product and they quickly realized that diversification of the offer was needed and that additional product value was needed.
The purpose of the traceability system is to link the final product made from aromatic or medicinal plants to the place of origin, specie of origin, method of harvesting, harvester, processor and producer. By having a QR code placed on a particular end product, the consumer can easily obtain more information than those described on the label of the product, and can choose which product is most relevant to their needs.

The success of a truffle plantation relies on the presence and abundance of T. melanosporum in the roots of the seedlings the farmers plant to obtain the crop of truffles. Yet, most farmers lack the skills to distinguish a plant with the fungus from one without it. Therefore, independent testing of the plants to be planted is critical to protect the farmers from errors or fraud in the nurseries leading to the sale of plants that will never produce truffles. Our aim was to develop a test that a trained technician could perform in a short period of time to keep the cost low.

Showing the potential of remote sensing to model mushroom yields is a first step for the future development of small-scale predictive models.
Nature has been the source of aromatic plants and herbs for thousands of years, and their use as medicines, enhancers of food aroma, preservatives, or cosmetics is well known from antiquity. However, the great development of animal product industry, in combination with the growing consumers’ demand for higher quality and more environmentally friendly products during the later years, led the food industry to begin to search for alternative solutions in animal nutrition. The introduction of aromatic plants as natural feed additives can be considered as one of them.
Forest management adaptation to the production of equally worth non-wood forest products – a practical opinion
In the new context of multifuncionality, the development of management plans integrating both the wood and non-wood forest products (i.e. mushrooms and truffles) for a particular area, aiming to increase the total market value becomes a challenge. In the process of management plan formulation, additionally to the scientific knowledge, also the practical experience of collectors should be taken into consideration.

Methodology to assess the situation of a medicinal and aromatic plant species to apply a sustainable management in a specific context
A large number of the medicinal and aromatic plants (MAPs) on the market come from wild collection and some of them are being overexploited or exploited without following proper practices. Establishing an adequate management could maintain the use of some species without compromising their conservation and obtain a benefit for the rural community.
In order to collect, it is necessary to evaluate the situation of that species in the place where it is going to be collected to estimate if it can be considered a “resource” or not, and to do it following an adequate methodology.

Oils provenances, distributed under different ecological conditions in Tunisia.
At a first glance, imported Asiatic and genuine Mediterranean pine nuts seem to be similar in size, colour and aspect. Cheaper Chinese chestnuts can also be confused with European chestnuts, when botanic species and origin are not declared on the label, despite this information being mandatory by UNECE marketing standards (2013).
However, aspects such as nutritional values and processing quality, sustainability of collection from wild and of course the taste are highly important. Consumer awareness is vital in this regard. Hence , supply chain actors in the Mediterranean should work together to improve the product profiles of their gourmet nuts, quite distinct from the cheaper imports.
The attractiveness of the resin tapper's profession is a key point for the revival of natural resin extraction to be a success. The aim is to adapt the resin extraction method to reduce the difficulty of the resin tapper's work. In creating the Biogemme© method, Holiste has taken this aspect into account. This involves, in particular, the creation of an appropriate tool to mechanize the harvest.

The wide potential of resin acids as bioactive agents could be considered as very promoting products for new applications of the natural forms and their derivatives.
The objective of the present investigation was mainly focused on the assessment of the biological performance of the resin. Therefore, the evaluation of the antibacterial activity of the three Tunisian pine species Pinus pinaster, Pinus pinea, and Pinus halepensis were conducted in order to control four pathogenic bacteria species.
The exploitation of pine forests in Tunisia which covered up to 50% of the total forest area could contribute and generate additional income sources for forest populations. Until now, the resin extraction knowledge was very limited and outdated. In the present study, the assessment of the biological performance of the resin was the main objective in order to detect the antioxidant activity of three pine species in the Tunisian forest.
After harvesting, the resin takes the form of a homogeneous mixture. Its distillation makes it possible to obtain two products: rosin and turpentine oil. The objective of extraction is to isolate and sample these compounds accurately. In other words, it is a question of having the finest possible selectivity. The second objective is not to alter the molecules and thus take full advantage of its qualities.
The standardisation study facilitates the inclusion of wood from resin tapped pines in the Spanish standard UNE 56544 (Visual classification of sawn wood for structural use. Coniferous wood), in order to favour its use and marketing as structural wood.
Simultaneously, the study compares the physical-mechanical properties of resinated Pinus pinaster wood against non-resin wood under the same normative parameters (UNE 56544), so that the technical buyer can evaluate which product is the most suitable for the intended application.
Tuber melanosporum, the fungus that produces the priced Black Truffle, is adapted to Mediterranean droughts. Usually the production of truffles increases in years with higher precipitation. This hinted early farmers into watering the orchards to obtain better crops, but, what happens if we water too much? One of the reasons we do not find truffles in forests with abundant rains could be that in wetter conditions other fungi can outcompete T. melanosporum and displace it from the roots of the trees causing the disappearance of the fungus and the end to truffle production.
The cork used in the manufacture of natural cork stoppers or technical stoppers must meet a number of conditions, including being free of certain anomalies. The use of NIRS (near infrared spectroscopy) technology has proven to be a valid technique for detecting yellow stain and corkbark, which are defects that must be avoided due to their harmful effects on the properties of the cork.
Ziziphus jujuba, known as Chinese jujube, is a highly valued plant native to China. Three species are known in Tunisia: Ziziphus lotus, Ziziphus spina-christi and Ziziphus jujuba.
