Abstract

TORRES-GALLO, Ramiro; CHAVEZ-SALAZAR, Andrés  and  CASTELLANOS-GALEANO, Francisco Javier. Patents Related to the Use of Starches from Unconventional Sources for Microencapsulation and Product Development in the Food and Pharmaceutical Industries: A Review. TecnoL. [online]. 2023, vol.26, n.57, e301.  Epub Oct 26, 2023. ISSN 0123-7799.  https://doi.org/10.22430/22565337.2569.

The high demand for commercial starches obtained from cereals, tubers and some legumes in the food and non-food industry, raises the need to search for new sources of starches. The present work focused on analyzing published patents related to the use of starches extracted from non-conventional sources in microencapsulation processes and development of new products in agroindustry. Patents were searched through Google Patents®, World Intellectual Property Organization (WIPO®, Lens® and PatentInspiration® free version. A maximum of 119 published documents were found, particularly Google Patents®. The analysis evidenced a significant increase (50%) in the period 2015 to 2022, showing the importance and interest in the exploration, invention and intellectual property protection, of methods and technologies that use unconventional starches to improve functional properties in the development of new products such as functional foods and pharmaceuticals, as well as microencapsulated wall material of bioactive compounds, essential oils, probiotics and in food matrices, highlighting the interest in patenting methods and modification processes, with more practical and efficient processes in terms of functionality, preparation times, costs, versatility and reduction of effluents. However, the most used starch sources continue to be the conventional one, which, due to its high demand, raises the need to promote the exploration of inventions that allow the technological, operational and economic development of non-conventional starches needed in the pharmaceutical and food industry.

Keywords : Functional foods; cross-linked starches; bioactive compounds; functional properties; spray drying.
