Definitions
- the subject of the present invention is granules containing an active substance, their method of preparation and their use in human or animal nutrition.
- the invention relates to granules containing sodium butyrate.
- Compounds derived from butyric acid have many beneficial biological effects, particularly on the digestive system, by stimulating the growth of the intestinal walls and the development of the microorganisms of the intestinal flora. In particular, they selectively exhibit an antimicrobial effect on certain strains of microorganisms of the digestive system. For example, they limit the development of bacteria: Clostridium acetobutylicum, Escherichia Coli, Streptococcus cremoris, Lactococcus lactis and cremoris, and Salmonella strains, while Lactobacillus and Streptococcus bovis strains are less affected by these.
- sodium butyrate has the advantage of being in the solid state and stable up to a temperature above 250°C.
- sodium butyrate is sensitive to acidic environments such as those found in the stomach, in which it hydrolyzes to form butyric acid which is then volatile or in liquid form facilitating its absorption in the stomach.
- acidic environments such as those found in the stomach, in which it hydrolyzes to form butyric acid which is then volatile or in liquid form facilitating its absorption in the stomach.
- direct oral absorption of sodium butyrate particles primarily results in dissolution and absorption in the stomach, which limits the uptake of sodium butyrate into the intestinal tract.
- the intestinal tract is made up of the small intestine, also called the small intestine, and the large intestine ending in the colon.
- the environment evolves and differs in particular by the pH and the presence of enzymes.
- the protection of the sodium butyrate particles must allow dissolution along the intestinal tract and not only bioavailability at the level of the small intestine.
- there is a need for protection allowing enteric release of sodium butyrate particles in the large intestine, in particular in the colon.
- Patent EP 2 352 386 describes a process for the preparation of granules containing particles of sodium butyrate in a fatty matter matrix in which calcium sulphate is incorporated into the matrix in order to promote the gastric resistance of the granule.
- Patent EP 2727472 teaches a process for preparing granules of butyrate particles in fat by extrusion, which then involves the coating of a gastric protective layer.
- PCT application WO 2018/033935 describes a process by successive sprays in order to obtain a multilayer granule of sodium butyrate, fatty acid and minerals crossing the gastric barrier of ruminants.
- one of the aims of the present invention is to provide granules comprising particles of sodium butyrate protected in a fatty matter matrix, having gastric resistance giving them protection in the stomach and allowing them prolonged release in the intestinal tract.
- Another object of the invention is to provide a population of granules comprising particles of sodium butyrate, in the form of stable powders, easily handled and adapted to the application for which said granules are intended.
- Another object of the invention is to provide a process for the preparation of granules comprising particles of sodium butyrate, having properties of gastric resistance and appropriate intestinal release.
- Another object of the invention consists in providing an animal or human food composition comprising such granules.
- the present invention relates to a granule comprising:
- a fat matrix comprising fatty acids encapsulating said sodium butyrate particles, said granule maintaining its morphology following in vitro tests simulating gastric and enteric digestion, said granule exhibiting gastric resistance conferring protection on the particles of sodium butyrate in the stomach and exhibiting a prolonged release of the particles of sodium butyrate in the intestinal tract.
- a granule comprising particles of sodium butyrate encapsulated in a fatty matter matrix containing fatty acids and obtained under specific preparation conditions retains its morphology in digestion media gastric and enteric. This results in a structural resistance of the matrix, after in vitro tests of digestions simulating the environment of the stomach, the small intestine and the large intestine, this structural resistance allowing gastric resistance of the particles of sodium butyrate in the stomach and prolonged release of sodium butyrate particles along the intestinal tract.
- gastric digestion we mean the degradation of ingested products in the stomach by gastric acidity and gastric juices.
- Gastric digestion can be simulated in vitro by a solution having a composition close to gastric fluid.
- Gastric fluid (or gastric juice) secreted by the stomach contains agents such as hydrochloric acid and certain enzymes, such as pepsin, which lyse proteins.
- gastric conditions can be simulated by a solution comprising water maintained at an acid pH of between 1 and 4 and a proteolytic enzyme, for example of the pepsin type, said enzyme being present in a content ranging from 0.025 to 2 .5% by weight, relative to the total weight of the solution.
- a proteolytic enzyme for example of the pepsin type
- Pepsin breaks down food bolus proteins by hydrolyzing amino acid peptide bonds.
- enteric digestions we mean enteric digestion in the small intestine and that in the large intestine.
- enteric digestion in the small intestine we mean the degradation of ingested products in the environment of the small intestine.
- enteric digestion in the small intestine is simulated in vitro by a solution having a composition close to the fluid present in the small intestine, in particular comprising pancreatin.
- Pancreatin is an enzyme derived from pancreatic juice.
- Enteric digestion in the large intestine means the breakdown of ingested products in the enteric environment of the large intestine.
- Enteric digestion in the large intestine is simulated in vitro by a solution having a composition close to the fluid present in the large intestine, in particular comprising lipase.
- Lipase is a digestive enzyme secreted by the pancreas.
- the in vitro test simulating enteric digestion in the large intestine used is adapted from the Boisen method.
- morphology of the granule is meant the external shape of the granule.
- the inventors have surprisingly observed that after the digestion tests adapted according to the Boisen method, the granules of the invention maintain their morphology.
- the maintenance of the granule morphology indicates that the structure of the fat matrix of the granules is preserved for the three tests simulating the digestions, gastric and enteric.
- gastric resistance is meant a resistance to the degradation of granules in the gastric environment. This “gastric resistance is generally determined by the residual quantity of sodium butyrate in the granule after simulation of gastric passage, for example for two hours in gastric fluid medium.
- sustained release is meant a gradual release of sodium butyrate from its encapsulating fat matrix along the digestive tract, generally by digestion or solubilization of the encapsulating fat matrix by digestive enzymes, bile salts or microorganisms.
- This "sustained release” is generally determined by the quantity released from the sodium butyrate by the granules after simulation of enteric passage, for example for four hours in a fluid simulating the small intestine and for 18 hours in a fluid simulating the large intestine.
- the morphological analysis of the granules can be carried out by observation using an optical or electron microscope, preferably using a scanning electron microscope.
- the present invention relates to a granule comprising:
- a fat matrix comprising fatty acids encapsulating said particles of sodium butyrate, said granule maintaining its morphology following in vitro tests simulating gastric and enteric digestion, said granule having gastric resistance conferring protection on the butyrate particles of sodium in the stomach and exhibiting a prolonged release of sodium butyrate particles in the intestinal tract and in which the level of butyric acid is less than 5%, in particular less than 2%, in particular less than 1%, in particular less than 0.5%, preferably less than 0.1% of the total amount of sodium butyrate

- the granules were crushed and were extracted in an organic phase of hexane.
- Sodium butyrate is not soluble in hexane, it should remain in its solid form while butyric acid is miscible with hexane.
- the extracted solutions were then analyzed by CPG, phase chromatography, in order to determine the quantity of butyric acid in the organic phase. It should be noted that there was no visual observation of fatty acid dissolution in the organic phase.
- Example 14 Rate of esterification by extraction in aqueous phase
- the granules of the products of the invention PR1G1F and PCaRIGIF are compared with the marketed product Adimix®disccision.
- the granules were crushed and were extracted in water.
- the solutions were then analyzed by ion chromatography. The method does not identify whether the butyrate is in the acid (butyric) or basic (butyrate) form in the granule.
- Table 9 reports the content of butyric acid or butyrate present in the extracted aqueous solution.
- PR1G1F and PCaRIGIF have a sodium butyrate titer close to the initial nominal value of 30% unlike the Adimix@geniecision product.
- Adimix®precision product has a titer of 22.4% indicating that part of the butyrate initially introduced is not available in the form of butyric acid or butyrate.
- the hypothesis is the presence of butyrate bound to other molecules which may result from the esterification reaction with fatty acids or triglycerides. This hypothesis seems to be confirmed by the analysis reported in Example 15 below.
- Example 15 Identification of the presence of ester by phase change analysis in basic medium.
- Table 10 below reports the results of extraction of Adimix®Estimation during a phase change in a basic medium compared with the results obtained by extraction in water.
- Table 10 content of sodium butyrate or butyric acid after phase change in basic medium.
