Introduction
Rafael Díaz-Sobac, currently develops research projects that have as their axis the study of the functional biological activity of metabolites present in food: neurotoxic effects, of alteration to behavior and learning, as well as of biodegradant activity of contaminants. Also, research continues on coatings and their application in post-harvest storage of fruits using biopolymers, now incorporating elements of nanostructuring and traceability through sensorization. Due to his academic experience, he also participates in work groups that promote educational innovation in Industry 4.0.

Cassava (Manihot esculenta Crantz) is a plant that contains neurotoxins such as linamarin and lotaustraline. Its long-term consumption is associated with neuronal damage and contributes to the development of motor impairment in humans and rats. We investigated the effects of the consumption of cassava juice on renal and hepatic function and motor i...
Our scientific articles have been cited for the period March-August 2019 in the 41 papers published in the international scientific journals by authors from 18 countries – India (26 times), Iran (12), China (9), Mexico (3), Portugal (3), Japan (3), Egypt (2), Germany (2), United Kingdom (2), USA (2), Canada (1), Spain (1), Switzerland (1), Vietnam...
Cyanogenesis is an enzyme-promoted cleavage of β-cyanoglucosides; the release of hydrogen cyanide is believed to produce food poisoning by consumption of certain crops as Cassava (Manihot esculenta Crantz). The production of hydrogen cyanide by some disruption of the plant wall is related to the content of two β-cyanoglucosides (linamarin and lotau...
Chenopodium quinoa is an herbaceous plant that possesses green polymorphic leaves. They are traditionally consumed in America and are considered nutritive vegetables. Most vegetables are considered valuable sources of micronutrients, such as mineral, vitamins, carbohydrates and dietetic fiber; however, because they are poor in proteins, they are co...
Knowledge related to the genetic improvement of quinoa has been increasing in recent years, demonstrating an effective advance in obtaining morphological characteristics meant to achieve uniformity in the quantity and quality of the production obtained in the field. For this research, quinoa flour harvested in Mexico and Chile, the latter of which...
Introduction: Acetone cyanohydrin (ACH) is a toxic substance present in cassava roots (Manihot esculenta Crantz) which results from enzymatic hydrolysis of linamarin. Long-term consumption is associated with 2 neurological disorders: konzo and tropical ataxic neuropathy. Previous studies have evaluated behavioural alterations linked to ACH consumpt...
Data and information quality have been recognized as essential components for improving business efficiency. One approach for the assessment of information quality (IQ) is the manufacturing of information (MI). So far, research using this approach has considered a whole document as one indivisible block, which allows document evaluation only at a g...
Recent reports have shown that commercial orange juice is rich in biogenic amines. Consumption of foods containing large amounts of biogenic amines increase hypertensive crisis and high levels of histamine and tyramine, which have been implicated as causative agents in a number of food poisoning episodes. In addition, accumulation of tryptamine in...
Los materiales de empaque proporcionan protección física y crean las condiciones fisicoquímicas apropiadas para proporcionar una vida útil adecuada.

Acrylamide is a vinyl monomer that is widely used for the synthesis of polyacrylamides, the treatment of drinking water, and as an additive in cosmetics. Acrylamide is also produced during the thermal processing of carbohydrate-rich foods. Although the potential toxic effects of acrylamide have been reported, few studies have evaluated biochemical...
Introduction
This study evaluated the protective effects of 2 commercial formats of Ginkgo biloba on motor alterations induced by cassava (Manihot esculenta Crantz) juice consumption in male Wistar rats.
Methods
The effects were evaluated with the open field and swim tests at 0, 7, 14, 21, and 28 days of treatment, one hour after administering the...

Some vegetable foodstuffs contain toxic compounds that, when consumed, favour the development of certain diseases. Cassava (Manihot esculenta Crantz) is an important food source, but it contains cyanogenic glucosides (linamarin and lotaustralin) that have been associated with the development of tropical ataxic neuropathy and konzo. In rats, intrape...
Modifications of the phytosanitary control in fruit in the pre- and post-harvest processes by exogenous application of biomolecules with insecticide activity have motivated the theoretical-experimental investigation of biomolecular systems. Essential oils such as limonene, monoterpenes like 3-carene, and halogenated monoterpenes like mertensene hav...

Microencapsulation by molecular inclusion technique was applied by using β-cyclodextrin to reduce the degradation of carotenoids and capsaicin present in the habanero chili oleoresin. The molecular inclusion complex was prepared in the proportions 20:80 and 30:70 oleoresin:β-cyclodextrin, respectively, and stored for 5 weeks in a range of aw = 0.10...
The long-term consumption of cassava (Manihot esculenta Crantz) juice produce neurotoxic effects in the rat, characterized by an increased motor activity in the open field test and presence of uncoordinated swim (i.e., lateral swimming), in the swim test; which has been associated with damage in the hippocampus (CA1). On the other hand, flavonoids...
Chemical assisted floralinduction is a common practice in manila mangoe fruit, however, the effects on post-harvest fruit quality is still notclear, hence the present study aimed to evaluate, the ripening process in mangoe fruit harvested from orchards treated with paclobutrazol (PBZ). The results showed that the use of PBZ reduced the production o...
Cellular oxidative stress produced by an increase in free radicals is one of the factors that promote the development of chronic degenerative diseases; therefore, consuming natural antioxidants helps minimize their negative effects. This study evaluated the cytotoxicity of the soursop extract (Annona muricata), its cytoprotective capacity against o...
El consumo de frutas frescas y plantas comestibles ha sido ampliamente recomendado principalmente debido al aporte nutricional y de biomoléculas con actividad antioxidante como los compuestos fenólicos y flavonoides. Sin embargo, las lectinas, también son un importante grupo de proteínas de origen no inmune, presentes en este grupo de alimentos y q...
