The present invention relates to a production process, composition and use of an artificial honey based on the use of inverted sugar, preferably using the enzyme invertase from yeast, with the addition of nutritive components such that the final syrup has a formulation similar to that of natural honey and can have improved pharmaceutical functions and biological functions, being healthier. The artificial honey of the present invention relates to a product of strictly plant origin, which is produced without the use of animal work or biological materials, and can be commercialized in various sectors, including the vegan sector. More specifically, the artificial honey of the present invention is produced from inverted sucrose, preferably by means of the enzymatic catalysis of VHP/VVHP/demerara brown sugars rich in minerals, vitamins and natural antioxidants of great pharmacological interest and various types of substances of interest. The artificial honey of the present invention has no chemical substances that are harmful to human health (e.g. pigments, preservatives or other chemical additives) added to it or produced in it, but can be flavored and/or aromatized with artificial honey flavoring, flavoring identical to natural honey and, optionally, natural honey flavoring, and may also contain fiber, vitamin supplements, minerals, vitamins, amino acids, natural extracts, being optionally directly consumed or used for manufacturing other food products.
