Produce plant natural aroma-forming substances

The fragrance or smell are substances produced by components in the food that are responsible for its organoleptic qualities. They mainly involve the sense of smell and taste. These substances determine, among other things, the sense of pleasure while eating. Although this may seem a trivial matter, the fragrance may be partially responsible for the evolutionary conditioning of the human being to distinguish between safe and dangerous foods.

Springham , Vivian Moses , Ronald E. It was the first book to treat the science and business of technology as an integrated subject and was well received by both students and business professionals.

All chapters in this second edition have been updated and revised and some new chapters have been introduced, including one on the use of molecular genetic techniques in forensic science. Experts in the field discuss a range of biotechnologies, including pesticides, the flavor and fragrance industry, oil production, fermentation and protein engineering. On the business side, subjects include managing, financing, and regulation of biotechnology. Some knowledge of the science behind the technologies is assumed, as well as a layperson's view of buying and selling.

As with the first edition, it is expected that this book will be of interest to biotechnology undergraduates, postgraduates and those working in the industry, along with students of business, economics, intellectual property law and communications.

Agarwood Aquilaria spp. Production being confined only to certain small pockets of South and Southeast Asia, agarwood is arguably the costliest wood in the world. Formation of fragrant agarwood resin is the outcome of complex biotic, abiotic, and physical stress on the Aquilaria trees.

Essential oils are fragrant, volatile substances, which different plants parts, essentially flowers, leaves, fruits, roots, may contain. They are lightly distillated with a vapor from raw plant material. The essential oils have a wide range of cosmetic and medical actions due to the presence of up to complex organic compounds with different chemical structure in their composition. The properties of essential oils are apparent by their complex pharmacological, biochemical and clinical effects due to their action on three levels: molecular, psychoemotional, and on the level of nervous system - because every smell has several chemical substances. The mechanisms of essential oils are made up of local, reflex and total resoptive actions. Molecules of aromatic compounds, when interacting with olfactory receptors, evoke emotional response.

Over the last two decades, rapid progress in the field of synthetic biology has opened several avenues for the heterologous de novo production of complex biological compounds, such as biofuels, pharmaceuticals, and food additives in microbial hosts. This minireview addresses the usage of the yeast Saccharomyces cerevisiae as a microbial cell factory for the production of flavour and aroma compounds, thereby providing a path towards a sustainable and efficient means of producing what are normally rare, and often expensive plant-derived chemicals. Synthetic biology is one of the most rapidly evolving branches of the biological sciences. Numerous examples have been recently reported of the successful implementation of synthetic biology in microorganisms such as Saccharomyces cerevisiae , such as for the production of valuable biomedical compounds [ 1 ] or biofuels [ 2 , 3 ].

An essential oil is a concentrated hydrophobic liquid containing volatile easily evaporated at normal temperatures chemical compounds from plants. Essential oils are also known as volatile oils , ethereal oils , aetherolea , or simply as the oil of the plant from which they were extracted, such as oil of clove.

Microbiology & Experimentation

Plants represent a rich source of nutrients for many organisms including bacteria, fungi, protists, insects, and vertebrates. Although lacking an immune system comparable to animals, plants have developed a stunning array of structural, chemical, and protein-based defenses designed to detect invading organisms and stop them before they are able to cause extensive damage. Humans depend almost exclusively on plants for food, and plants provide many important non-food products including wood, dyes, textiles, medicines, cosmetics, soaps, rubber, plastics, inks, and industrial chemicals. Understanding how plants defend themselves from pathogens and herbivores is essential in order to protect our food supply and develop highly disease-resistant plant species.

Yeast cells are often employed in industrial fermentation processes for their ability to efficiently convert relatively high concentrations of sugars into ethanol and carbon dioxide. Additionally, fermenting yeast cells produce a wide range of other compounds, including various higher alcohols, carbonyl compounds, phenolic compounds, fatty acid derivatives and sulfur compounds. Interestingly, many of these secondary metabolites are volatile and have pungent aromas that are often vital for product quality.

Plant breeders have made considerable advances producing cultivars with higher yields, resistant to pests and diseases, or with high nutritional quality, without paying enough attention to flavour quality. Indeed, consumers have the perception that fruit aromas and flavours have declined in the last years. Attention is given nowadays not only to flavoured compounds but also to compounds with antioxidant activity such as phenolic compounds. Fruit flavour is a combination of aroma and taste sensations. Conjugation of sugars, acids, phenolics, and hundreds of volatile compounds contribute to the fruit flavour. However, flavour and aroma depend on the variety, edaphoclimatic conditions, agronomical practices and postharvest handling. This chapter reviews the aromas and flavours of the most important fruits and discusses the most recent advances in the genomics, biochemistry and biotechnology of aromas and flavours. Generation of Aromas and Flavours. Quality in horticulture can be defined as the traits of a given commodity, regardless of its yield [ 1 ]. Here, we not only include visual appearance, ability to endure postharvest processing but also chemical and nutritional composition and flavour. Great advances have been made in horticultural breeding, obtaining fruits with characteristics that are those that growers e.

Essential oil

Plants provide us with an enormous array of chemicals essential to industry and to our daily lives. But why are the chemicals there and why does the plant produce them? Please be aware that the information provided on this page may be out of date, or otherwise inaccurate due to the passage of time. For more detail, see our Archive and Deletion Policy. In their poisons, antibiotic agents, prickles and foul tastes, they developed defences against attack long before human stockades and pesticides. Many of the chemicals produced by plants are linked to the ingenious strategies that plants have developed to help them flourish and survive. Some of their defences include the thick, insulating bark of many trees, and the vicious thorns on roses. But what is it that makes the stem hairs on stinging nettles produce a rash. Why do some plants produce saps that have an extremely bitter taste; and why do others produce antibacterial substances?

This review covers literature data summarizing, on one hand, the chemistry of essential oils and, on the other hand, their most important activities. Essential oils, which are complex mixtures of volatile compounds particularly abundant in aromatic plants, are mainly composed of terpenes biogenerated by the mevalonate pathway. These volatile molecules include monoterpenes hydrocarbon and oxygenated monoterpens , and also sesquiterpenes hydrocarbon and oxygenated sesquiterpens.
