Raising entire male pigs: comparison of growth performance and meat quality of ...

Rearing entire male pigs presents several benefits, including enhanced feed efficiency, reduced environmental impact, and improved animal welfare. However, the risk of boar taint poses a significant challenge to pork quality. The objective of this pilot study is to evaluate growth performance, meat quality and the incidence of boar taint in intact male pigs of the Bısara breed (BI) and a terminal cross (TC). Fi...

Microwave-assisted extraction for the sustainable recovery and valorization of ...

This study investigates the potential of Pinus pinaster subsp. atlantica bark, a forestry byproduct fromnorthernPortugal, as a source of phenolic compoundswithstrongantioxidant properties. Microwave-assisted extraction (MAE) was used to optimize recovery, assessing the effects of solvent composition (water, ethanol, and 50:50 water–ethanol), extraction time (15 or 30 min), and temperature (90, 110, or 130 ◦C) u...

Industrial use of bioenergy and high-value molecules extracted from winemaking ...

From the concept of circularity, a new industrial revolution is arising where waste as unwanted or unusable material is virtually unknown. In present times, indicators describe the main constraints posed on our world`s future development: population growth, carbon dioxide in the atmosphere, energy consumption, overuse of minerals and natural resources, and shortage of water, which leads to a future zero-waste s...

Enhanced HPLC method for boar taint quantification

Boar taint is an unpleasant odour found in the carcasses of entire male pigs, resulting from androstenone and skatole accumulation during pubertal development, and impacting pork quality. This study proposes the validation of an adapted chromatographic method for quantifying skatole and androstenone in the pigs’ liquid fat using fluorescence detection. A good chromatographic separation was achieved, with skatol...

Comparative study of pretreatments on coconut fiber for efficient isolation of ...

Pretreatment is an essential step for breaking the recalcitrant structure of lignocellulosic biomass and allowing conversion to high-value-added chemicals. In this study, coconut fiber was subjected to three pretreatment methods to compare their impacts on the biomass’s structural characteristics and their efficiency in fractionating the biomass. This comparative approach was conducted to identify mild biomass ...

EU citizens’ perception of risks posed to the sustainability of EU food security

Food security is a core global sustainability challenge and priority of the UN Sustainable Development Goals. Events like COVID-19, extreme weather, and global conflicts have significantly impacted food prices, as evidenced by the FAO food price index rising from 95.1 in 2019 to 143.7 in 2022, heightening EU food security concerns. The European Commission responded with a food supply contingency plan. According...

Validation of a small-scale method for determination of phosphorus in meat and ...

The purpose of this study was to evaluate the applicability of an alternative analytical technique to the reference method for phosphorus detection in meat and meat products established by ISO 2294:1974, revised by ISO 23776:2021. When an analytical method is modified or a new one is developed and implemented, it should be validated before being accepted for routine determinations. Furthermore, it is necessary ...

Corncob as carbon source in the production of xanthan gum in different strains ...

Xanthan gum (XG) is a biopolymer obtained in fermentation and used as a rheology control agent in aqueous systems and in stabilizing emulsions and suspensions. XG, together with other polysaccharides, can form soft, cohesive composite gels. The carbon source in the fermentative process is responsible for one-third of the production costs, and the search for less expensive and sustainable alternatives is ongoing...

The chemical characterisation of the maritime pine bark cultivated in northern ...

Maritime pine, scientifically known as Pinus pinaster, holds a vital role in Iberian Peninsula forests, primarily as a source of wood for panels, paper, and cellulose production. Recently, there has been a growing interest in utilising agroforestry by-products to yield valuable chemicals for applications in various sectors, including the food, pharmaceutical, and bioenergy industries. This study aimed to assess...
