Download or read book Sorghum Tannins written by Frederico Ribeiro de Barros and published by . This book was released on 2013 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the calories in cereal foods come from starch. Decreasing starch digestibility is fundamental to prevent obesity and diabetes. This study investigated interactions of condensed tannins (proanthocyanidins-PA) and other sorghum phenolic compounds with starch molecules and their effect on in vitro starch digestibility. High tannin (predominant in large molecular weight PA, 80%), black (monomeric polyphenols) and white (low in polyphenols) sorghum phenolic extracts were cooked with starches varying in amylose content. Starch pasting properties, polyphenol profile and in vitro starch digestibility were evaluated. Unlike other treatments, samples with tannin phenolic extracts had significantly (P 9́Þ 0.05) lower setback in the test using a Rapid Visco Analyser (RVA) compared to control. The same treatments had the least extractable phenol and PA contents after cooking with all starches. These evidences suggest interactions between starch molecules and PA. Furthermore, after mixing tannin phenolic extracts with pure amylose/amylopectin, extractable polymeric PA was in much lower concentration (62% less) in presence of amylose compared to amylopectin. This drop in concentration increased to 85% when purified tannin extract (90% polymeric PA) was used. This indicates a stronger interaction between amylose and large molecular weight PA. When high amylose starch was used in an autoclave cooking/cooling technique, the RS content of control (26.4%) was similar (P > 0.05) to samples with black phenolic extracts (27%); samples with tannin phenolic extracts increased RS to about 40%. The RS increased to 46% when purified tannin extract was used. All these evidences suggest that sorghum condensed tannins, specifically the polymeric PA, directly interacted with amylose, increasing RS content, whereas the monomeric polyphenols did not. This study opens opportunities to use tannin sorghum to develop products for diabetics and weight control, high in dietary fiber and natural dark color. In the other part of this project, polyphenols from black and tannin sorghum bran were extracted using an Accelerated Solvent Extractor (ASE) and eco-friendly solvents such as water, and mixtures ethanol/water. ASE at 120 and 150 degrees C using 50 and 70% ethanol/water was efficient in extracting as much phenols (45 mg GAE/g) and 12% more antioxidants (628 [mu]mol TE/g) from black sorghum compared to conventional methods using aqueous acetone and acidified methanol. Therefore, ASE extracts from black sorghum could be used in beverages and in colorants containing high antioxidant content.

Book excerpt: In vitro starch digestibility of raw and processed wholegrain sorghum flours did not correlate with condensed tannin content in each of the 15 flours tested. However, tannin extracts both reduced and enhanced amylase activity depending on conditions. This trend was clear in extracts but more complex in wholegrain flours.
Download or read book Nutritional and Toxicological Significance of Enzyme Inhibitors in Foods written by Mendel Friedman and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean protei ns are wi de 1 y used inhuman foods ina vari ety of forms, including baby formulas, flour, soy protein concentrates, soy protein isolates, soy sauces, textured soy fibers, and tofu. The presence of inhibitors of digestive enzymes in soy proteins impairs nutritional quality and possible safety of this impportant legume. Normal processing conditions based on the use of heat do not completely inactivate these inhibitors, so that residual amounts of plant protease inhibitors are consumed by animals and man. Inhibitors of digestive enzymes are present not only in legumes, such as soybeans, lima beans, and kidney beans, but also in nearly all plant foods, including cereals and potatoes, albeit in much smaller amounts. The antinutritional effects of inhibitors of proteolytic enzymes have been widely studied and can be ameliorated by processing and/or sulfur amino acid fortification. A more urgent concern is reports that rats fed diets containing even low levels of soybean-derived inhibitors, which are found in foods such as soy-based baby formulas, may develop over their lifespan pancreatic lesions leading eventually to neoplasia or tumor formation. On the other hand, recent stUdies suggest that certain enzyme inhibitors from plant foods may prevent cancer formation in other tissues. A key question, therefore, is whether inhibitors from plant foods constitute a human health hazard.

This book was released on 2024-01-15 with total page 1630 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crop plants cater not only to our basic F5 (food, feed, fiber, fuel, and furniture) needs but also provide a number of nutraceuticals with potential nutritional, safety and therapeutic properties. Many crop plants provide an array of minerals, vitamins, and antioxidant-rich bioactive phytochemicals. Increasing incidences of chronic diseases such as cancer, diabetes and HIV, and malnutrition necessitate global attention to health and nutrition security with equal emphasis to food security. This compendium compiles results of researches on biochemical, physiological and genetic mechanisms underlying biosynthesis of the health and nutrition related nutraceuticals. It also explores the precise breeding strategies for augmentation of their content and amelioration of their quality in crop plants under all commodity categories including cereals and millets, oilseeds, pulses, fruits and nuts, and vegetables. The compendium comprise 5 sections dedicated to these 5 commodity groups and presents enumeration on the concepts, strategies, tools and techniques of nutraceutomics. These sections include 50 chapters devoted to even number of major crop plants. These chapters present deliberations on the biochemistry and medicinal properties of the nutracuticals contained; genetic variation in their contents; classical genetics and breeding for their quantitative and qualitative improvement; tissue culture and genetic engineering for augmentation of productivity and quality; and sources of genes underlying their biosynthesis. They also include comprehensive enumeration on genetic mapping of the genes and QTLs controlling the contents and profile of the nutraceuticals and molecular breeding for their further improvement through marker assisted selection and backcross breeding tools. Prospects of post-genomic precise breeding strategies including genome-wide association mapping, genomic selection, allele mining, and genome editing are also discussed. This compendium fills the gap in academia, and research and development wings of the private sector industries interested in an array of subjects including genetics, genomics, tissue culture, genetic engineering, molecular breeding, genomics-assisted breeding, bioinformatics, biochemistry, physiology, pathology, entomology, pharmacognosy, IPR, etc., and will also facilitate understanding of the policy making agencies and people in the socio-economic domain and research sponsoring agencies.

Available in PDF, EPUB and Kindle. Book excerpt: The prevalence of naturally occurring toxins in plant and animal foods represents one of the most significant food safety issues, drawing the attention of both scientists and regulators alike. This unexplored area related to food quality is indeed a big concern for consumers, various regulatory authorities, and food industries. Apart from essential nutrients, several food crops are capable of producing a vast array of nonnutritious secondary metabolic products. These toxins produced as secondary metabolites have the potential to exhibit both beneficial and deleterious effects in both human beings and animals. Nevertheless, there has been huge progress in agricultural practices and food processing technologies, but still the number of nonnutritive substances and naturally derived toxins persist in our diet. Handbook of Plant and Animal Toxins in Food: Occurrence, Toxicity, and Prevention, focuses on various selected toxins in foods derived from plants as well as animals. The prominent plant toxins include solanine and chaconine, mushroom toxins, phytates, tannins, oxalates, goitrogens, gossypol, phytohemagglutinins, erucic acid, saponins, cyanogenic glycosides, enzyme inhibitors, BOAA (lathyrogens), toxic amino acids and toxic fatty acids. The prominent animal toxins covered in the book include various seafood toxins, shellfish toxins and biogenic amines. Key Features: Presents complete information about a plethora of toxins Provides quick and easy access to data on major plant and animal toxins Covers distribution of toxins in the plant and animal kingdom Provides comprehensive information on chemistry, safety and precautions of each toxin Commencing with a brief introduction of food toxins, this book is designed in such a way that the readers will be introduced to toxicity, safety and occurrence of each toxin selected. It also discusses the in-depth detailed information on food poisoning and its prevention. The book will also shed light on foodborne illness associated with toxins. The primary audience for this work will be food scientists, food toxicologists, university scholars and college students. Furthermore, the book will be of immense help for public health officials, pharmacologists, and food safety officers who are involved with enforcing regulations meant to ensure the safety of a particular food
