Definitions

  • the present application relates to the field of the conservation of perishable foodstuffs, in particular foodstuffs, such as plant products.
  • Essential oils can exercise their activity by evaporation of their components, in particular terpenoids, such as terpenes.
  • Another possibility is to absorb essential oils on a solid but oil-soluble product, such as polyterpenes or pine resin.
  • C0 2 is therefore an indicator for monitoring the metabolism and maturation of plant products.
  • C0 2 is used to control the conservation needs of said products.
  • the present invention therefore relates to a sustained-release formulation of a terpenoid with a phenolic group, said formulation comprising at least one salt of a terpenoid with a phenolic group, with a base.
  • terpeneoid means terpenes and their modified derivatives resulting from the addition or deletion of an alkyl group and / or the addition of oxygen atom.
  • terpenoids we mean in particular hemiterpenoids (1 isoprene units, in C5), monoterpenoids (2 isoprenic units, in C10), sesquiterpenoids (3 isoprenic units, in C15), diterpenoids (4 isoprenic units, in C20), sesterterpenoids (5 isoprenic units, in C25), triterpenoids (6 isoprenic units, in C30), tetraterpenoids (8 isoprenic units, in C40), polyterpenoids with a larger number of isoprenic units.
  • Tepene is understood to mean hydrocarbons resulting from the combination of several isoprenic units.
  • phenolic group means a phenyl group substituted by at least one hydroxyl function (OH).
  • said terpenoid with a phenolic group can be chosen from eugenol, thymol and carvacrol.
  • the salts thus formed with the terpenoid with a phenolic group with said bases are therefore chosen from eugenates, thymates and carvacrates.
  • said terpenoid may be present as a mixture in said formulation, for example in the form of essential oil which contains it.
  • said formulation can include the corresponding essential oil, salified.
  • Essential oils include clove oil as a source of eugenol, thyme oil as a source of thymol, and oregano oil as a source of carvacrol.
  • the formulation of the invention therefore comprises an essential oil comprising at least one terpenoid with a phenolic group, said oil being salified with a base.
  • bases Mention may in particular be made, as base, of bases, and in particular sodium hydroxide, potassium hydroxide, lime, or even quaternary ammonium, amines, such as triethylamine or trialkanolamines, in particular bases having a low voltage of steam to avoid evaporation.
  • the base is chosen from soda, caustic potash, lime or soda or potassium carbonate.
  • the formulation of the invention can also comprise one or more non-salified phenolic terpenoids, in order to obtain an initial rapid evaporation of the non-salified phenolic terpenoids for protection. immediate, combined with prolonged release of salified phenolic group terpenoids.
  • the formulation of the invention can also comprise one or more non-phenolic terpenoids, in order to obtain an initial rapid evaporation of the non-phenolic terpenoids for immediate protection, combined with the prolonged release of terpenes containing a phenolic group.
  • the formulation can also comprise one or more formulation agents, such as preservatives, perfumes, binders, fillers, colorants, etc.
  • formulation agents such as preservatives, perfumes, binders, fillers, colorants, etc.
  • said terpenoid salts containing a phenolic group are bagged in a porous film.
  • a film mention may be made of polyethylene, paper, or any other material, such as woven or non-woven textiles, the thickness and / or nature of which allows the diffusion of vapor.
  • said film consists of polyethylene film.
  • the present invention therefore also relates to a controlled release packaging of a terpenoid with a phenolic group, comprising a sachet made of a porous film, said sachet containing a formulation according to the invention.
  • the present invention also relates to a method for preserving plant products comprising:
  • said sachet which contains the phenolic group terpenoid salts is in contact with the atmosphere of the stored plant products.
  • the stored plant products and said sachet containing the formulation are stored in a closed enclosure making it possible to limit gas exchanges with the outside.
  • the C0 2 released by the respiration of the plant products reacts with the phenolate salt of said terpenoid to gradually release the non-salified terpenoid which can therefore diffuse into the storage atmosphere, through the porous film.
  • the formulation therefore contains terpenoid salts with phenolic group, in solid form which, when brought into contact with C0 2 , release the terpenoid with phenolic group, which will thus be able to diffuse gradually.
  • the amount of terpenoids released is a function of the amount of C0 2 released by the plant products into the storage atmosphere. The amount of terpenoids released will therefore depend on the level of C0 2, which depends on the metabolism of plant products.
  • the quantity of terpenoid salts containing a phenolic group is adjusted according to the quantity of plant products stored, their metabolism, storage conditions and the envisaged storage period, in order to balance the quantity of terpenoids released with the volume of C0 2 released.
  • an excess of base in the formulation in particular an excess of strong base in order to have a slowing down of evaporation, the base being first consumed by the C0 2 before the reaction of C0 2 with terpenoid salts containing a phenolic group.
  • Peaches are stored in 2 closed 10-liter polypropylene containers. Each container contains 6 peaches.
  • the first container is the control container, containing only peaches.
  • the containers are stored at 4 ° C.
  • control peaches lost 2.2% of their weight while the peaches stored in the container containing the eugenate lost only 1.6% of their weight. Peaches preserved in the presence of eugenate therefore lost 27% less weight than control peaches.
  • Sulfur dioxide is generally used as a preservative for fresh grapes and vine derivatives. Tests have been carried out to identify whether sulfur dioxide could be replaced by clove oil vapor. Grapes of the Parlet variety, freshly harvested, one day before the test were packaged in packages of 1.5 - 1.6 kg in closed plastic containers of approximately 5 liters. The treatments consisted of applying potassium eugenate + lime (CaO) 5/5. The tests were repeated 4 times. The charging time was 15 days at a constant temperature of 25 degrees C. The observations were made eight or fifteen days after incubation, for the following parameters:
