Market Opportunities and Challenges for Indian Organic Products
Organic agriculture offers trade opportunities for farmers in the developing and developed countries. This market of organic products is expected to grow globally in the coming years and high growth rates over the medium term (from 10-15 to 25-30 %) are expected (Yussefi and Willer, 2002). This organic market expansion makes it possible for farmers to reap the benefits of a trade with relatively high price premiums (Yussefi and Willer, 2002). However, this market is not very well known to most farmers, especially those living in the developing countries. Furthermore, information about it is not readily available to farmers in the developing countries. The absence of sufficient technical and market information and financial support also means that few farmers will risk changing their method of production.
In developing countries it is therefore essential for major key players (e.g. NGOs, farmer organizations, traders, exporters etc.) that promote organic farming to have up-to-date information on the available opportunities (market requirements) and trends of the organic market. One example is India, a country with a huge number of small farmers who still use traditional methods and do farming with few agricultural inputs. NGOs that promote organic farming and other organizations support farmers in these aspects. An organic movement is now emerging in India on different levels (producer groups, trainers and advisors, certification bodies and processors and traders). So dissemination of information about the opportunities and challenges for Indian organic products on the domestic and international market is of fundamental concern in order to allow continued development of the organic agriculture movement in this country
Text Localization in Video Using Multiscale Weber's Local Descriptor
In this paper, we propose a novel approach for detecting the text present in
videos and scene images based on the Multiscale Weber's Local Descriptor
(MWLD). Given an input video, the shots are identified and the key frames are
extracted based on their spatio-temporal relationship. From each key frame, we
detect the local region information using WLD with different radius and
neighborhood relationship of pixel values and hence obtained intensity enhanced
key frames at multiple scales. These multiscale WLD key frames are merged
together and then the horizontal gradients are computed using morphological
operations. The obtained results are then binarized and the false positives are
eliminated based on geometrical properties. Finally, we employ connected
component analysis and morphological dilation operation to determine the text
regions that aids in text localization. The experimental results obtained on
publicly available standard Hua, Horizontal-1 and Horizontal-2 video dataset
illustrate that the proposed method can accurately detect and localize texts of
various sizes, fonts and colors in videos.Comment: IEEE SPICES, 201
Effect of locally available spices on the organoleptic and storage periods of Heterotis niloticus
Investigation were carried out on the effect of some locally available species in the enhancement of the organoleptic quality and the storage periods of smoked Heterotis niloticus using Pprosopis africana as common smoke sources. Samples of fresh H. niloticus were bought, cut into chunks while extract juice from pepper, ginger rhizomes, garlic, onion bulb were used as sources of spices. Samples of fish were divided randomly into five (5) batches dipped into spice extract juices for 10 minutes drained and smoked with common firewood. Treatment without spice extract juice served as control. Each batch of fish was smoked for 7 hours on a drum-made smoking kiln products were individually packaged in polythene bag stored at room temperature and used for sensory evaluation and microbial analysis. Results of the sensory evaluation indicated that there was significant difference (P0.05) in the microbial analysis. The garlic juice extract had the longest storage period with minimum total plate and mould count after 8 week
Phytochemical Content and Antioxidant Activity in Tradisional Balinese Babi-guling Spices
The traditional Balinese richly spiced swine-grill (Babi-guling) has been increasingly popular even among both the domestic and foreign tourists. The traditional grill is very unique in taste as it contains two main components, i.e. the pork and the unique Balinese spices, which probably could work antagonistically one against the other in affecting people health. The pork because of its rich content of saturated fatty acid is a risk of atherosclerosis, while the spices appear to be rich in antioxidatns. This is a preliminary atherosclerosis experimental study designed to screen qualitatively the phytochemical contents of the spices and to test their antioxidant activity and strength in different concentrations in vitro. The methods used included Willstater test, NaOH 10% test, Meyer test, Leiberman-Burchard test, test for saponin, and test for phenol. The antioxidant activity was estimated by using DPPH (2,2-diphenyl-1-pricrylhydrazyl) test. The treatment applied to the spice before testing was raw and cooked by heating it inside the pig's body cavity. The concentrations of spices tested were 100, 1000 and 8000 ppm. The results of our study revealed that the phytochemical content of the spices were flavonoids, terpenoids and phenolic compounds, but saponin and alkaloids were not detected. The antioxidant activity was ineffective in concentration of 100 ppm (percentage of reduction < 50%), effective in concentration of 1000 ppm (percentage of reduction 50-60%), and too thick in concentration of 8000 ppm (percentage of reduction >100%. We inferred that the traditional Balinese richly spiced swine-grill contains flavanoids, terpenoids and phenol which can act as antioxidants in vitro, and the most effective concentrations to decrease the free radicals were between 1000-8000 ppm
Mixed Spices at Culinary Doses Have Prebiotic Effects in Healthy Adults: A Pilot Study.
Spices were used as food preservatives prior to the advent of refrigeration, suggesting the possibility of effects on microbiota. Previous studies have shown prebiotic activities in animals and in vitro, but there has not been a demonstration of prebiotic or postbiotic effects at culinary doses in humans. In this randomized placebo-controlled study, we determined in twenty-nine healthy adults the effects on the gut microbiota of the consumption daily of capsules containing 5 g of mixed spices at culinary doses by comparison to a matched control group consuming a maltodextrin placebo capsule. The 16S ribosomal RNA sequencing data were used for microbial characterization. Spice consumption resulted in a significant reduction in Firmicutes abundance (p < 0.033) and a trend of enrichment in Bacteroidetes (p < 0.097) compared to placebo group. Twenty-six operational taxonomic units (OTUs) were different between the spice and placebo groups after intervention. Furthermore, there was a significant negative correlation between fecal short-chain fatty acid propionate concentration and Firmicutes abundance in spice intervention group (p < 0.04). The production of individual fecal short-chain fatty acid was not significantly changed by spice consumption in this study. Mixed spices consumption significantly modified gut microbiota, suggesting a prebiotic effect of spice consumption at culinary doses
Botanical insecticides prescription for fish pest control and infestation free protein yield
The dry powders of four local species namely Piper guineense Schum and Thonn, Aframomum melegueta Schum, Zingiber officinale Rose; Capsicum annum Miller at three concentrations of 15g, 20g and 25g.kg were evaluated for their insecticidal effects against the larval of the dried fish weevil Demestes maculates Degeer. All the four species showed some effectiveness with P. guineense given a 100% mortality at the end of 72 hours at the three concentrations. The other species though gave less mortality were able to slow down the rate of development of the larvae to the adult siz
