Manufacturing
NATURAE has developed a production process that allows us to obtain unique aloe vera dietary supplements worldwide. In our production process, we work exclusively from fresh organic aloe vera leaves, taking care of every detail and every stage to maximize the quality of the final product and avoid any type of degradation that reduces the quality of the final product.
Among the processes developed by NATURAE we have implemented an ozone generation system, which, together with the cold purification system and the final stabilisation of the product by HPP (high pressure process), allows us to obtain aloe vera dietary supplements stable at room temperature with a shelf life of 24 months, but without chemical preservatives or heat treatments that could degrade the active compounds of the product, such as vitamins and aminoacids, or modify the natural taste and smell of the raw material.
NATURAE has a newly built factory since 2019 where the latest technology focused on the quality of the final product has been implemented. It has IFS and IASC (International Aloe Science Council) certifications that certify the quality of our production process and the products we produce in our facilities.
HIGH PRESSURE PROCESSING (HPP) FOR MICROBIOLOGICAL STABILIZATION OF ORGANIC ALOE VERA DIETARY SUPPLEMENTS
The High-Pressure Processing (HPP) is a non-thermal method where food products, in a flexible packaging, are introduced into a steel vessel and are treated with very high isostatic pressure (300-600 MPa/43,500-87,000 psi) transmitted by the water.
Pressures over 400 MPa / 58,000 psi with a refrigeration temperature (+ 4ºC to 10ºC) or ambient temperature, inactive the microorganisms like bacteria, viruses, molds and yeasts, that could be in the product, increasing its shelf life and securing their safety.
The great advantage of HPP is that it respects the sensory and nutritional quality of the aloe vera due to the absence of heat treatment, thereby maintaining the original freshness throughout its shelf life.
There are two fundamental principles on which the application of high pressures is based (Cheftel, 1991):
The first indicates that the pressure is transmitted uniformly and instantly throughout the biological material treated by high pressure, considering it as an isostatic process.
This process avoids deformation of the product, despite being subjected to such high pressures, and makes it very homogeneous and not present overtreated areas.
The second refers to the principle of Le Chatelier indicating that the phenomena accompanied by a volume decrease (chemical reactions, modification of molecular conformations) are favored by an increase in pressure and vice versa. According to this principle, the application of high pressure shifts the equilibrium of a process towards the state that occupies less volume. In principle a protein macromolecule, the formation of hydrogen bonds, hydrophobic interactions rupture and ion pairs are accompanied by a volume restriction favored by the pressure (Cheftel, 1991).
The main attraction of this technology is that can be performed the treatment at cold or room temperature and the quality parameters of the original product are preserved (Cheftel, 1992). Initially its main advantage was that it could be used as a partial or complete substitute for heat treatment when the aim was to microbial destruction.
