Almost every agricultural crop, including wheat, can be infected by fungi during plant growth and/or after harvest. Fusarium graminearum is one example of a fungus that is prevalent pathogen in wheat. Mycotoxins, such as Fusarium graminearum, pose a serious health risk to humans and animals. Deoxynivalenol (DON) is a trichothecene mycotoxin produce...

Byproducts generated by the food industry represent an alternative to obtain functional ingredients. Byproducts of tropical fruits, such as papaya skin and seeds, represent a source of bioactive compounds (BC), which could change during fruit ripening. Effect of ripening stage (RS) on BC content and antioxidant properties of edible pulp, skin and s...

Knotweeds (Reynoutria Houtt.) are plants native to the Far East. Japanese knotweed was introduced from Japan to the unsuspecting West by the horticultural activities of Philippe von Siebold via his nursery at Leiden in the 1840s. By 1854, the plant had arrived at the Royal Botanic Gardens in Edinburgh. The plants were then sold by a large number of...

Licorice (Glycyrrhiza glabra L.) oil is obtained from a perennial plant and is widely used as a natural sweetener and flavoring agent. Its main bioactive component that imparts a sweet flavor is glycyrrhizin; in addition, contains some volatile compounds, flavonoids, and saponins. Therefore, due to its sweetness and flavoring characteristics, licor...

Changing the physicochemical properties of starch by chemical modification is a common process. Starches can be modified to alter their hydrophobicity by treatment with octenyl succinic anhydride (OSA). The physicochemical properties of OSA starches from corn, tapioca, rice, potato and wheat were studied. The increase of swelling volume and pasting...

Characterization of the fine structure of octenylsuccinic anhydride (OSA) starch would lead to a better understanding of functional properties. OSA rice and tapioca starches were analyzed using microscopy, liquid chromatography and nuclear magnetic resonance. Chain length distribution of amylopectin changed significantly (P<0.05) after OSA esterifi...

Hydrogen sulfide (H2S) has been considered as a phytotoxin for almost 300 years, having deleterious effects on plant growth and survival. However, in recent years, H2S has been added to nitric oxide (NO) and carbon monoxide (CO) as a newly categorized group of biologically active gases termed as gasotransmitters, due to its capacity to control a ra...

Oxygen, carbon dioxide, and nitrogen are gases produced under modified atmosphere packaging (MAP). Nitrogen helps to prevent oxidation by displacing oxygen, whilst CO2 acts as a bacteriostatic. Each of them plays different roles in the biochemical and physiological responses of fruits and vegetables. Respiration rate and ethylene synthesis are amon...

Deoxynivalenol (DON) is a mycotoxin affecting wheat quality. The formation of the "masked" mycotoxin deoxinyvalenol-3-glucoside (D3G) results from a defense mechanism the plant uses for detoxification. Both mycotoxins are important from a food safety point of view. The aim of this work was to analyze DON and D3G content in inoculated near-isogenic...

Deoxynivalenol (DON) is a mycotoxin found in wheat that is infected with Fusarium fungus. DON may also be converted to a type of "masked mycotoxin", named deoxynivalenol-3-glucoside (D3G), as a result of detoxification of the plant. In this study, DON and D3G were measured using gas chromatographic (GC) and liquid chromatography-mass spectrometry (...
