ENERGY EFFICIENCY INDICATORS IN THE FOOD INDUSTRY: A SYSTEMATIC REVIEW

Energy and its ramifications make up a large part of the discussions in the agendas of various countries. Along with the energy resource, energy efficiency is also being reported in studies on ways to improve its use in industries. In the food industry, in particular, its use is intensive in its manufacturing processes, and thus the indicators that measure the use of this feature have become important. The paper uses the method of a systematic literature review to search for data related to the food industry and what are the energy efficiency indicators adopted in the processes. The objective of the research is to report which are the indicators of energy efficiency adopted in the food industry and the advances achieved with its adoption. The results indicate a broad field of research in this industry sector because the indicators used in measuring process efficiency are still poorly understood and adopted.
