Additives have been used in the food sector for centuries, aiming to maintain or improve food quality in terms of freshness, appearance, texture and taste. Most food additives are synthetic chemical compounds classified as antioxidants, antimicrobials, colorants and sweeteners. In the last decades, several synthetic food additives have been correlated with adverse reactions in humans, which has caused the safety of synthetic food additives to be reviewed and discussed by international organizations. At the same time, there is increasing consumer demand for more natural and environmentally friendly food products and additives. Therefore, synthetic food additives have been replaced with natura...
La gulupa (Passiflora edulis Sims var. edulis), es considerada como un fruto exótico con características sensoriales notables como su coloración morada, fragante olor y sabor agridulce. La región de Anaime ubicada en el Municipio de Cajamarca – Tolima, se caracteriza por su altitud y clima húmedo, propicio para el cultivo de este fruto. El objetivo del trabajo fue analizar las características fisicoquímicas y actividad antioxidante de una fracción de la parte comestible del fruto de la gulupa, cultivada en la zona estudio. Los parámetros humedad, actividad de agua (aw), potencial de hidrógeno (pH), acidez total titulable (ATT), conductividad eléctrica, solidos solubles totales (...
Lives from an invisible community—the migrant farmworkers of the United States The Grapes of Wrath brought national attention to the condition of California’s migrant farmworkers in the 1930s. Cesar Chavez and the United Farm Workers’ grape and lettuce boycotts captured the imagination of the United States in the 1960s and ’70s. Yet today, the stories of the more than 800,000 men, women, and children working in California’s fields—one third of the nation’s agricultural work force—are rarely heard, despite the persistence of wage theft, dangerous working conditions, and uncertain futures. This book of oral histories makes the reality of farm work visible in accounts of hardshi...
The exciting and heartbreaking biography of a woman willing to fight for liberation during a tumultuous time in Mexican history--Provided by publisher.
This book reports on fundamental research, cutting-edge technologies and industrially-relevant applications in biomedical engineering. It covers methods for analysis, modeling and simulation of biological systems, reporting on the development and design of advanced biosensors, nanoparticles and wearable devices. It covers applications in disease monitoring and therapy, tissue engineering, sport and rehabilitation, and telehealth. It also reports on engineering methods for improving and monitoring medical service, and on advanced robotic applications. Gathering the proceedings of the XLV Congreso Nacional de Ingeniería Biomédica (CNIB2022), organised by the Mexican Society of Biomedical Engineering, this book offers a timely snapshot on technologies and methods in bioengineering, and on challenges related to their practical implementation in the health sector.
'NDiaye is a hypnotic storyteller with an unflinching understanding of the rock-bottom reality of most people's life.' New York Times ' One of France's most exciting prose stylists.' The Guardian. Obsessed by her encounters with the mysterious green women, and haunted by the Garonne River, a nameless narrator seeks them out in La Roele, Paris, Marseille, and Ouagadougou. Each encounter reveals different aspects of the women; real or imagined, dead or alive, seductive or suicidal, driving the narrator deeper into her obsession, in this unsettling exploration of identity, memory and paranoia. Self Portrait in Green is the multi-prize winning, Marie NDiaye's brilliant subversion of the memoir. Written in diary entries, with lyrical prose and dreamlike imagery, we start with and return to the river, which mirrors the narrative by posing more questions than it answers.
