Technology of regeneration and recycling of frying fats by using a new microgranulated nanosorbent in the catering

Abstract

Abstract The article considers the technological capabilities and prospects for regeneration of frying fats in the catering enterprises using active filtration by a micro-granulated nanosorbent with subsequent recycling. The offered recycling technology involves the restoration of the quality of degraded frying fat with the purpose of its reuse and/or subsequent utilization. It is known that degraded frying fats contain products of oxidative and hydrolytic decomposition which vary according to their composition and structure. Actually, there is no universal technology that would provide the quality and safety indicators of frying fat for its further usage both in catering or for recycling in the market of secondary raw materials. Development of new microgranulated nanosorbent is based on fundamentally new technologies for modifying the surface of highly dispersed clay minerals of the Russian raw materials market using carbon nanomaterials. The granular sorbent is more preferable for use in catering, it allows easy separation of oil from the adsorbent without significant effort spent on filtration. The granular sorbent is lighter, more voluminous, and it significantly increases the adsorption efficiency even by contact method. The authors propose the technology of regeneration and recycling of frying fats with using new microgranulated nanosorbent in the catering enterprises.
