  • Effect of N-Hexane Oil Extract of Two Spices on Serum Lipid Profile and Blood Glucose Concentration of Albino Rats by Ogunka-Nnoka C
    Global Journal of Science Frontier Research Biological Science Volume 13 Issue 6 Version 1.0 Year 2013 Type : Double Blind Peer Reviewed International Research Journal Publisher: Global Journals Inc. (USA) Online ISSN: 2249-4626 & Print ISSN: 0975-5896 Effect of N-Hexane Oil Extract of Two Spices on Serum Lipid Profile and Blood Glucose Concentration of Albino Rats By Ogunka-Nnoka C. U. & Igwe F. U. Rivers State University of Science and Technology, Nigeria Abstract - Consumers are concerned with their health and physical fitness and are seeking for alternative plant products with potential for providing nutrients with enhanced health benefits. Hence, this study investigates the effect of mixture of Ehuru (Monodora myristica) and Njasang (Ricinodendron heudelotii) oil extract on serum lipid profile and blood glucose concentration of albino rats. The spices were processed into fine flour and the oil was extracted with n-hexane as the solvent. A total of twenty five rats weighing 125-160g were separated into five groups of five each to represent control, olive oil and varying concentrations of the spices. After acclimiatization for one week, experimental administration of the extract was carried out daily for 28 days. Blood samples were collected by cardiac puncture into tubes. A portion of the blood was used for fasting blood glucose determination. Serum was separated from the other portion and used for assay of lipid profile using standard kit methods. The results obtained showed percentage fatty acid yield for Ehuru and Njasang as 79.54 and 81.0 (polyunsaturated) and 13.40 and 15.0 (monounsaturated) respectively. Fasting blood glucose assay showed that only rats in group 1 (6.46mmol/L) became significantly (p<0.05) hyperglycaemic while groups 2-4(6.03, 5.98 and 5.53mmol/L) showed a hypoglycaemic effect with respect to control (6.13mmol/L).

  • Diversifying Food and Diets, Using Agricultural Biodiversity to Improve
    Diversifying Food and Diets Currently 868 million people are undernourished and 195 million children under five years of age are stunted. At the same time, over 1 billion people are overweight and obese in both the developed and developing world. Diseases previously associated with affluence, such as cancer, diabetes and cardio-vascular disease, are on the rise. Food system-based approaches to addressing these problems that could enhance food availability and diet quality through local production and agricultural biodiversity often fall outside the traditional scope of nutrition, and have been under-researched. As a consequence, there remains insufficient evidence to support well-defined, scalable agricultural biodiversity interventions that can be linked to improvements in nutrition outcomes. Agricultural biodiversity is important for food and nutritional security, as a safeguard against hunger, a source of nutrients for improved dietary diversity and quality, and strengthening local food systems and environmental sustainability. This book explores the current state of knowledge on the role of agricultural biodiversity in improving nutrition and food security. Using examples and case studies from around the globe, the book explores current strategies for improving nutrition and diets and identifies key research and implementation gaps that need to be addressed to successfully promote the better use of agricultural biodiversity for rural and urban populations, and societies in transition. Jessica Fanzo was formerly a Senior Scientist with Bioversity International and is now an Associate Professor of Nutrition at Columbia University in New York. Danny Hunter is the Global Project Coordinator at Bioversity International for the UNEP/FAO/GEF project ‘Mainstreaming biodiversity conservation and sustainable use for improved human nutrition and wellbeing’ and Adjunct Associate Professor, School of Agriculture and Wine Sciences, Charles Sturt University, Australia.

China, 9 - 14 April 2018 REVISION OF THE CLASSIFICATION OF FOOD AND FEED: IMPACT OF REVISED COMMODITY GROUPS AND SUBGROUPS IN TYPE 03 GRASSES, TYPE 04 NUTS, SEEDS AND SAPS AND TYPE 05 HERBS AND SPICES ON CODEX MRLS (Prepared by the Electronic Working Group chaired by the United States of America and co-chaired by the Netherlands) BACKGROUND 1. Background on the discussion of the revision of the Classification of Food and Feed (CXM 4-1989) can be found in the reports of the 36th – 49th sessions of the Committee on Pesticide Residues (CCPR) including relevant sessions of the Codex Alimentarius (CAC) held from 2004 to 2017.1 2. One of the terms of reference2 from CCPR49 (2017) was to consider how the Codex MRLs (CXLs) adopted by CAC and available in the existing Codex database for maximum residue limits (MRLs) for pesticides would be impacted by the revised commodity groups and subgroups in Types 03, 04 and 05. 3. The Committee has previously agreed that “no changes would be made to existing CXLs until such time as JMPR reviews were completed as per current procedures for the establishment of Codex schedules and priority list of pesticides. The Committee agreed that the same approach would be taken when reviewing other commodity groups in the database following the adoption of revised commodity groups in the Classification”.3 4. To achieve the above, a specific CXL at the level of the old group-CLX for the relocated commodity will keep its existing CXL, and at the same time the commodity will be excluded from the new group-CXL.

Background and Objectives: NTFPs, such as wild foods, medicinal plants, and raw materials for handicrafts, make significant contributions to rural livelihoods. NTFPs can help fulfil households’ subsistence and consumption needs, serve as a safety-net in times of crises, and provide cash income. In particular, the processing of NTFPs has often been suggested to positively influence sustainable economic development in rural areas. However, despite rising interest and recognition of the potential contributions of such industries as key sources of employment and their strategic role in overall growth strategies of developing countries, many NTFP processing enterprises remain in the informal sector and an in-depth understanding of the underlying factors is lacking. This review aims to identify enabling and constraining factors affecting NTFP processing enterprises. Materials and Methods: Using systematic review methodology, studies investigating commercialized, processed NTFPs and their economic impacts have been identified and the current evidence base with regard to NTFP processing and small and medium sized enterprise (SME) development synthesized.
