The short time that people have to cook their own food has led industries to satisfy the need for ready-to-eat products. This has motivated a progressive increase in studies that can determine the time at which the product can be safely consumed (shelf life). There are several methods for determining the shelf life of products; but regardless of the method used, the key is to know the minimum and/or maximum values of the indicators that define their deterioration. These values of spoilage indicators can change according to the compositional conditions of the food or the conditions under which it is stored during its shelf life. This review provides values for indicators used in tests for the determination of food shelf life, according to their nature, and environmental conditions, as way to be used by researchers as a reference in their predictions. The results of this research show scie...

In recent decades there has been a considerable global increase in urban population, industrial productivity, energy demand, waste generation, and the emission of greenhouse gases from energy conversion. The agricultural, forestry, textile and food sectors generate large amounts of waste and their environmental impact has become a major cause for concern in societies around the world. Current efforts are concerned with maximization of combustion efficiency and energy-related processes in general by making use of industrial residues and reducing particulate matter. The present review addresses the availability of different types of biomass that can be used to produce renewable energy and focuses on agricultural, forestry, urban and industrial residues. It also provides a description of the physical and calorific characteristics of the various raw materials available for the manufacture of...

Currently there is a great demand for food products containing functional properties and/or bioactive compounds. One of the fruits that has been widely studied is the murta (Ugni molinae), which appears to contain various beneficial health properties. This review compiles scientific information on the functional and beneficial properties of murta for human health, such as the main components associated with anti-inflammatory activity, antimicrobial activity, antioxidant activity, nutritional composition, other uses of murta, economic aspects, and current and future challenges of murta, all based on updated scientific work.
