Multipurpose Antioxidants based on Food Industry Waste: Production and Properties Evaluation

Published on: 20th June, 2025

Some preliminary results of studies on the assessment of the possibilities and prospects for obtaining products with a high Antioxidant Activity Index (AOA) from the waste of the coffee beverage production industry - "silver skin" (SC, silverskin, CS) are presented.The obtained data on the extraction of SC with aqueous-alcoholic extractants, the effect of extraction conditions on the yield of extracts, and extractive substances are discussed. It is reported on the production of dry powders of extracts that retain their properties during long-term storage.Data on the antioxidant properties of both liquid and dry forms of extracts are presented and good AOA of the studied objects is noted in comparison with the "standard" antioxidant - rosemary extract, and it is also shown that the AOA of dry forms of extracts can be increased by doping with synergists - polyphenols of natural genesis. The antioxidant activity of the obtained compositions was studied on real objects - animal fats and natural dyes, the results of which confirmed the prospects of the studied antioxidants (AO) for practical purposes.

Walnut Pruning Residues as a Renewable Energy Resource for Greenhouse Heating in the South-Central Region of Chihuahua, Mexico

Published on: 29th July, 2025

The objective of this research was to estimate the energy potential of walnut pruning residues (biomass) as a renewable resource for use in greenhouse heating systems in the south-central region of the state of Chihuahua. To achieve this, data were collected on the weight of fresh firewood generated per tree based on trunk diameter, considering three common pruning methods practiced in the area. Additionally, the percentage of weight loss during the biomass drying process was determined, and the regional area cultivated with walnut trees was documented. Based on this information, the potential energy availability and the feasibility of its use as a sustainable energy source for the agricultural sector under controlled climate conditions were calculated.
