Chapter
Enzymes are biocatalysts that are used in countless catalytic reactions. These biocatalytic systems are capable of specifically manipulating biomolecules found in living organisms. However, there are enzymes whose biocatalytic activity results in a rapid deterioration of the quality of food and some can even deteriorate the health of people. Theref...
Chapter
Acetylcholinesterase (AChE) inhibitors are an important therapeutic strategy in Alzheimer’s disease (AD). AChE hydrolyzes a neurotransmitter acetylcholine in choline and acetate, which reduces the amount of acetylcholine. The inhibition of AChE has been studied for a long time not only for AD but also in anxiety treatment. There are some plants wit...
Chapter
Digestive enzymes with hydrolytic activity, such as α-amylase, ensure hydrolysis of starch as a high-molecular-weight food component. The regulation of the enzymatic activity of amylase makes it possible to control the level of hydrolysis and absorption of simple sugars from starch. This control is essential for the treatment of metabolic diseases...
Chapter
The present chapter is focused on the aspects of heat transfer applied in food science and technology. Heat transfer is vital on cooking processes. During food preparation, the energy can be transferred by convection, conduction, and radiation. This chapter describes some forms of heat transfer considering the radiation (microwave and ultrasound) a...

One of the relevant problems in today's agriculture is related to phytopathogenic microorganisms that cause between 30–40% of crop losses. Synthetic chemical pesticides and antibiotics have brought human and environmental health problems and microbial resistance to these treatments. So, the search for natural alternatives is necessary. The genus St...

The Tetranychidae family includes mites causing severe damage to agricultural fields. The red spider mite, Tetranychus merganser Boudreaux (Acari: Tetranychidae), causes severe damage to several plant species grown as cash crops. Current red spider mite control depends mainly on chemical insecticides. There is a need for alternate control measures...

Tetranychidae family is a major group of mites causing serious damage in agricultural, vegetable and ornamental crops. Avocado bronze mite (ABM), Oligonychus punicae Hirst (Acari: Tetranychidae) causes major crop damage, defoliation and fruit abortion. At present, the control of this mite depends mainly on agrochemicals. Therefore it is necessary t...

Plant extracts (PEs) and essential oils (EOs) contain phytochemical compounds (PCs). Nev-ertheless, PCs can be degraded when applied on field. The use of nano-encapsulates (NEs) and micro-encapsulates (MEs) arise as an alternative to the application of botanical products. However, NEs and MEs with PCs in plant disease control have not been explored...
Chapter
Currently, lectins have acquired a great interest on the part of investigators due to the properties that they possess. Lectins are proteins present in plants, animals, and microorganisms. The main characteristic of this kind of protein is its ability to join sugar in a specific way. This ability made it a great tool in the treatment and diagnostic...

Introduction: In several regions of the world, Fusarium oxysporum causes losses on tomato crops; for control it, chemical fungicides are used. Nevertheless, these fungicides causing environmental and resistance problems; therefore, ecological alternatives as plant extracts have been developed. Due to the aim of this work, identify phytochemicals pr...
