Download or read book Food Hydrocolloids written by K. Nishinari and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well recognised that the texture of foods is an important factor when consumers select particular foods. Food hydrocolloids have been widely used for controlling in various food products their viscoelasticity, emulsification, gelation, dispersion, thickening and many other functions. An international journal, FOOD HYDROCOLLOIDS, launched in 1986 has published a number of stimulating papers, and established an active forum for promoting the interaction between academics and industrialists and for combining basic scientific research with industrial development. Although there have been various research groups in many food processing areas in Japan, such as fish paste (kamaboko, surimi), soybean curd (tofu), agar jelly dessert, kuzu starch jelly, kimizu (Japanese style mayonnaise), their activities have been conducted in isolation of one another. The interaction between the various research groups operating in the various sectors has been weak. Symposia on food hydrocolloids have been organised on several occasions in Japan since 1985. Professor Glyn O. Phillips, the Chief Executive Editor of FOOD HYDROCOLLOIDS, suggested to us that we should organise an international conference on food hydrocolloids. We discussed it on many occasions, and eventually decided to organise such a meeting, and extended the scope to include recent development in proteinaceous hydrocolloids, and their nutritional aspects, in addition to polysaccharides and emulsions.
Download or read book Advances in Chitin Chitosan Characterization and Applications written by Marguerite Rinaudo and published by MDPI. This book was released on 2019-04-23 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Functional advanced biopolymers have received far less attention than renewable biomass (cellulose, rubber, etc.) used for energy production. Among the most advanced biopolymers known is chitosan. The term chitosan refers to a family of polysaccharides obtained by partial de-N-acetylation from chitin, one of the most abundant renewable resources in the biosphere. Chitosan has been firmly established as having unique material properties as well as biological activities. Either in its native form or as a chemical derivative, chitosan is amenable to being processed—typically under mild conditions—into soft materials such as hydrogels, colloidal nanoparticles, or nanofibers. Given its multiple biological properties, including biodegradability, antimicrobial effects, gene transfectability, and metal adsorption—to name but a few—chitosan is regarded as a widely versatile building block in various sectors (e.g., agriculture, food, cosmetics, pharmacy) and for various applications (medical devices, metal adsorption, catalysis, etc.). This Special Issue presents an updated account addressing some of the major applications, including also chemical and enzymatic modifications of oligos and polymers. A better understanding of the properties that underpin the use of chitin and chitosan in different fields is key for boosting their more extensive industrial utilization, as well as to aid regulatory agencies in establishing specifications, guidelines, and standards for the different types of products and applications.
Download or read book Lipo chitooligosaccharides written by Tomas Allen Rush and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial signaling is the driver to initiate microbe-host and microbe-microbe interactions. When the host perceives a signal, it will somehow decide whether to activate innate immunity or mutualistic cooperation between the organism(s). However, decoding and understanding any coded signal is an enigma, especially if we do not know what organisms produce the signal and why they use it. Lipo-chitooligosaccharides are an example of a coded signal which are recognized as "symbiotic" communication signals produced by rhizobia and by two genetically different mycorrhizal fungi, Rhizophagus irregularis and Laccaria bicolor. Given the discovery of lipo-chitooligosaccharides being produced by such diverse fungi, here we tested the hypothesis that lipo-chitooligosaccharides are ubiquitous signal molecules among fungi. Using both biological assays (legume root hair branching and ENOD11 expression), and high-performance liquid chromatography coupled to mass spectrometry, we analyzed fungal exudates of 61 fungi across five phyla in the fungal kingdom and three species of oomycetes. We were able to detect lipo-chitooligosaccharides in fungal exudates in 55 fungi across the Fungal Kingdom with various lifestyles and growth habits but not in non-dimorphic yeasts (Saccharomyces cerevisiae and Candida glabrata) and oomycetes. Moreover, chitooligosaccharides were detected in all fungi and oomycetes tested. To further understand why non-symbiotic fungi would produce lipo-chitooligosaccharides, we tested the hypothesis that lipo-chitooligosaccharides is a quorum sensing molecule. We used specific chemically synthesized lipo-chitooligosaccharides (sulfated C16:0; non-sulfated C16:0; sulfated C18:1; and non-sulfated C18:1) and naturally produced chitooligosaccharides (CO4, CO5, and CO8). We were interested in answering the following questions: 1) Can exogenous lipo-chitooligosaccharides influence growth and development of a fungus that produces lipo-chitooligosaccharides? 2) Can exogenous lipo-chitooligosaccharides influence growth and development of a fungus that does not produce lipo-chitooligosaccharides? 3) What is the extent of growth and development affected by exogenous lipo-chitooligosaccharides in the Fungal Kingdom? To answer these questions, we tested these synthesized lipo-chitooligosaccharides against two ascomycetes; Aspergillus fumigatus, which produces lipo-chitooligosaccharides, and Candida glabrata, which did not have lipo-chitooligosaccharides detection. Moreover, we tested Rhodotorula mucilaginosa, which is a basidiomycete yeast, to determine if the lipo-chitooligosaccharides effect on fungi can be across phyla. Our results determined that exogenous lipo-chitooligosaccharides influence the behavior, growth, and development, and gene expression in fungi, regardless of their ability to produce lipo-chitooligosaccharides or not, and their phylogenic placement in the Fungal Kingdom. Finally, we wanted to test the hypothesis that the genes responsible for lipo-chitooligosaccharides production in fungi are homologous to the genes found in rhizobia. In the latter, the genes encoding for chitin synthase, chitin deacetylase, and acetyltransferase are well characterized and have been demonstrated to be responsible for lipo-chitooligosaccharides production based on gene knockout studies. We found two homologous chitin deacetylase genes in Aspergillus fumigatus Af293 strain that matched with rhizobia chitin deacetylase genes. We constructed a single and double chitin deacetylase knockout mutant to determine if chitin deacetylase encoding genes are indispensable for lipo-chitooligosaccharides production in fungi. Our results determined that the homologous chitin deacetylase genes are essential for lipo-chitooligosaccharides in fungi. In conclusion, results from this dissertation have determined that: 1) lipo-chitooligosaccharides are ubiquitous signal molecules found throughout the Fungal Kingdom, 2) lipo-chitooligosaccharides influence behavior, growth and development, and gene expression in fungi, and 3) rhizobia and fungi share homologous genes that are responsible for the production of lipo-chitooligosaccharides.
