CitationDevelopment of organic breads and confectionery. The National Food Centre Research Report No. 75. Eimear Gallagher et al. Dublin; Teagasc, 2005. ISBN 1841704326
AbstractRecently, there has been a significant increase in the number of launches of organic bakery products in Ireland. As a result, there is an increased need to identify suitable organic bakery ingredients for use in bread and confectionery formulations. However, only a limited number of scientific studies on the physical, chemical and functional properties of organic flours and ingredients exist. The effects of commonly-used ingredients in baking, i.e. organic improvers and fats, on the baking characteristics of organic products have not yet been reported and little is known about the influence of approved additives that may be beneficial to organic baking. Arising from these gaps in the knowledge base on the use of organic flours and ingredients, the objective of this study was to evaluate the chemical, rheological and baking characteristics of white, wholemeal and confectionery organic flours and to assess the baking potential of organic bakery ingredients, in particular improvers, fats and additives. Ingredients and baked goods were compared to non-organic controls.

Land Spreading of Animal Manures, Farm Wastes & Non-Agricultural Organic Wastes. Part 1 manure (and other organic wastes) management guidelines for intensive agricultural enterprises.Carton, Owen T.; Magette, William L. (Teagasc, 1999-05-01)The objective of the Teagasc Manure (and Other Organic Wastes) Management Guidelines for IAE are to provide an operational framework for the agronomically efficient and environmentally safe recycling of these organic by-products, maximising the benefits of nutrients they contain at minimum cost. The principles of the approach are equally applicable to the management of all manures and organic wastes applied to land. The approach includes programmes for controlling manure quantity and quality; operational procedures covering storage, transport and nutrient management; and a quality assurance programme. These Guidelines assign the importance of manure management on an equal footing with other production practices. Implementation of these Guidelines may entail higher costs c o m p a red with traditional practices. However, some of the benefits accruing from the improved management practices can partly or wholly offset the costs of implementation.
Snpdat: Easy and rapid annotation of results from de novo snp discovery projects for model and non-model organismsDoran, Anthony G; Creevey, Christopher J. (Biomed Central, 2013-02-08)Background: Single nucleotide polymorphisms (SNPs) are the most abundant genetic variant found in vertebrates and invertebrates. SNP discovery has become a highly automated, robust and relatively inexpensive process allowing the identification of many thousands of mutations for model and non-model organisms. Annotating large numbers of SNPs can be a difficult and complex process. Many tools available are optimised for use with organisms densely sampled for SNPs, such as humans. There are currently few tools available that are species non-specific or support non-model organism data. Results: Here we present SNPdat, a high throughput analysis tool that can provide a comprehensive annotation of both novel and known SNPs for any organism with a draft sequence and annotation. Using a dataset of 4,566 SNPs identified in cattle using high-throughput DNA sequencing we demonstrate the annotations performed and the statistics that can be generated by SNPdat. Conclusions: SNPdat provides users with a simple tool for annotation of genomes that are either not supported by other tools or have a small number of annotated SNPs available. SNPdat can also be used to analyse datasets from organisms which are densely sampled for SNPs. As a command line tool it can easily be incorporated into existing SNP discovery pipelines and fills a niche for analyses involving non-model organisms that are not supported by many available SNP annotation tools. SNPdat will be of great interest to scientists involved in SNP discovery and analysis projects, particularly those with limited bioinformatics experience.
The variation in morphology of perennial ryegrass cultivars throughout the grazing season and effects on organic matter digestibilityBeecher, Marion; Hennessy, Deirdre; Boland, T. M.; McEvoy, Mary; O'Donovan, Michael; Lewis, Eva (Wiley, 2013-09-19)The grass plant comprises leaf, pseudostem, true stem (including inflorescence) and dead material. These components differ in digestibility, and variations in their relative proportions can affect sward quality. The objective of this study was to determine the change in the proportion and organic matter digestibility (OMD) of leaf, pseudostem, true stem and dead components of four perennial ryegrass cultivars (two tetraploids: Astonenergy and Bealey and two diploids: Abermagic and Spelga) throughout a grazing season. The DM proportions and in vitro OMD of leaf, pseudostem, true stem and dead in all cultivars were determined during ten grazing rotations between May 2011 and March 2012. There was an interaction between rotation and cultivar for leaf, pseudostem, true stem and dead proportions. In May and June, Astonenergy had the highest leaf and lowest true stem proportion (P < 0·05). From July onwards, there was no difference in leaf or true stem proportion between cultivars. Bealey had the highest annual mean OMD (752 g kg−1) and Spelga the lowest (696 g kg−1; P < 0·05). The OMD followed the order leaf > pseudostem > true stem > dead. Bealey had the highest combined leaf and pseudostem proportion 0·92, which explains why it had the highest OMD. In this study, the tetraploid cultivars had the highest leaf and pseudostem proportion and OMD. For accurate descriptions of a sward in grazing studies and to accurately determine sward morphological composition, pseudostem should be separated from true stem, particularly during the reproductive stage when true stem is present.
