Labeling of meat products is key to guarantee quality and origin. Rising production costs and an increase in world trade are leading to an on-going growth of meat fraud. Hence, the objective of this study was to evaluate the potential of visible and near-infrared (Vis-NIR) spectroscopy to discriminate meat from different Canadian cattle feeding sys...
The application of hyperspectral imaging (HSI) has gained significant importance in the past decade, particulary in the context of food analysis, including potatoes. However, the current literature lacks a comprehensive systematic review of the application of this technique in potato cultivation. Therefore, the aim of this work was to conduct a sys...
The Esca complex is a grapevine trunk disease that significantly threatens modern viticulture. The lack of effective control strategies and the intricacy of Esca disease manifestation render essential the identification of affected plants before symptoms become evident to the naked eye. This study applies Convolutional Neural Networks (CNNs) to dis...
The potato ( Solanum tuberosum L.) is the world’s fifth most important staple food with high socioeconomic relevance. Several potato cultivars obtained by selection and crossbreeding are currently on the market. This diversity causes tubers to exhibit different behaviors depending on the processing to which they are subjected. Therefore, it is inte...
Nowadays, the meat industry requires non-destructive, sustainable, and rapid methods that can provide objective and accurate quality assessment with little human intervention. Therefore, the present research aimed to create a model that can classify beef samples from longissimus thoracis muscle according to their tenderness degree based on hyperspe...
Currently, there is a discrepancy between the number of occupational accidents in the agricultural sector reported by Spanish governmental sources and those actually occurring in general. This is mainly due to the official definition of ‘occupational accident’ in the current regulations. In order to be able to analyse all fatal accidents involving...
Precise and reliable identification of specific plant diseases is a challenge within precision agriculture nowadays. This is the case of esca, a complex grapevine trunk disease, that represents a major threat to modern viticulture as it is responsible for large economic losses annually. The lack of effective control strategies and the complexity of...
Industrial hemp (Cannabis sativa L.) is a plant native to Asia, and is considered to be a primary source of food, textile fiber, and medicines. It is characterized by containing minimal concentrations of delta-9 tetrahydrocannabidol (THC), which is the main psychoactive chemical component, and cannabidiol (CBD), a non-psychoactive substance. In mos...
Many endeavours in precision agriculture use some kind of sensor to gain relatively inexpensive information on the spatial and temporal variation in crops, soil, weeds, diseases, and so on. However, information about sensors is scattered throughout the literature. This text fills an important niche by bringing together information on a wide range o...
The potential loss of world crop production from the effect of pests, including weeds, animal pests, pathogens and viruses has been quantified as around 40%. In addition to the economic threat, plant diseases could have disastrous consequences for the environment. Accurate and timely disease detection requires the use of rapid and reliable techniqu...
Powdery mildew is a worldwide major fungal disease for grapevine, which adversely affects both crop yield and produce quality. Disease identification is based on visible signs of a pathogen once the plant has already been infected; therefore, techniques that allow objective diagnosis of the disease are currently needed. In this study, the potential...
Fuzzy set theory has developed a prolific armamentarium of mathematical tools for each of the topics that has fallen within its scope. One of such topics is data comparison, for which a range of operators has been presented in the past. These operators can be used within the fuzzy set theory, but can also be ported to other scenarios in which data...
The aim of this work was to investigate the feasibility of near-infrared spectroscopy (NIRS), combined with chemometric techniques, to detect fraud in minced lamb and beef mixed with other types of meats. For this, 40 samples of pure lamb and 30 samples of pure beef along with 160 samples of mixed lamb and 156 samples of
mixed beef at diferent lev...
A study carried out in Spain on the location of fire stations and their territorial coverage points out deficiencies in relation to care within a reasonable time frame. This article analyzes the use of Geographic Information Systems (GIS) to determine the territorial coverage and population served by fire services in a specific response time. This...
There exists a continuous research effort aiming to port methods for grayscale image processing to more complex imagery data. Color images were an initial target for such effort, but new technologies have lead to many other types of images. In this work we focus on hyperspectral images. Specifically, we analyze how to adapt the Upper-Lower Edge Det...
Recent years have brought a quick decay in prize of hyperspectral imagery equipment. As a consequence, new applications have appeared, a relevant example being the analysis of agro-food materials. Such applications need to be grounded on dedicated image processing operators, which fully accomplish with (and exploit) the characteristics of hyperspec...
In this study, the optical properties of potato flesh tissue were estimated using double-integrating sphere (DIS) measurements combined with an inverse adding-doubling (IAD) light propagation model. Total reflectance, total transmittance, and unscattered transmittance were measured for the wavelength range 500–1900 nm with 5-nm resolution. From the...
Potato is one of the most consumed products worldwide. According to this fact, quality control of potato and its products becomes essential to ensure the continuity of the supply. This chapter reviews various techniques currently used for this quality control. First, a description of the analytical techniques to measure various compounds present in...
BACKGROUND
Over the last two decades, the attractive colours and shapes of pigmented tubers and the increasing concern about the relationship between nutrition and health are contributing to the expansion of their consumption and specialty market. Thus, we have quantified the concentration of health promoting compounds such as soluble phenolics, mo...
The detain nation of the composition of potatoes is essential in order to meet the current demand for quality products. The traditional methods to measure potato components are both expensive and laborious; therefore, some authors have studied the application of faster and cheaper techniques such as near infrared spectroscopy (NIRS) to determine th...
Water-sensitive papers are a simple technique to check the coverage of a certain treatment applied in any crop. Although it is possible to visually determine if a treatment has been either insufficient or correct, it is advisable to analyse those papers by an image analyser to get reliable results. The objective of this study is to demonstrate the...
Potato (Solanum tuberosum L.) is one of the most important crops in the world being considered as a staple food in many developing countries. Potato industry likewise other vegetable and fruit industry is subject to the current demand of quality products. In order to meet this challenge, food industry is relying on the adoption of non-destructive a...
New agriculture implies a higher intensification of mechanization in order to increase the production. This fact has lead to an increase in the use of electric or pneumatic shears at pruning jobs, which brings associated a serious risk of cutting or amputation of fingers. To avoid these damages, the worker must use PPE (Personal-Protective-Equipmen...
