Recent research has shown that it is more effective to use substances contained in natural food products, including pectin. Pectin has a favorable effect not only under acute exposure to metals, but also with their prolonged entry into the body, which is typical for an environmental load of residents of industrial regions and modern megalopolis.\u0000The use of pectin substances as natural detoxicants requires research to preserve these substances in products and further use. Therefore, an important condition for using pectin concentrates is to determine the shelf life for safe consumption. Based on this, studies were conducted to determine optimal storage parameters and terms for pumpkin concentrate.\u0000The sequence and parameters of pectin concentrate production from Karina pumpkin pomace are justified.\u0000As a result of the study, it was found that during storage of pectin concentrate from Karina pumpkin pomace at a temperature of 8 °C for 10 months, the pectin content in the concentrate decreased by 0–12. 45 %, at 25 °C – by 0–63 %, compared to the control sample. Based on the results, it can be concluded that the safe storage period of pectin-containing concentrates from Karina pumpkin extracts at a temperature of 25 °C is 7 months, at 8 °C – 10 months.\u0000As a result of mathematical processing of experimental data, equations for the relationship of pectin amount with storage temperature, pH and time are obtained.","PeriodicalId":286770,"journal":{"name":"Food Chemistry eJournal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130819929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Feverfew is a prospective member of the Tanacetum genus. Recently an interest to this plant has grown. Sesquiterpene lactones and phenolic compounds are known to be cause its anti-inflammatory and antimigraine activity. The study of volatile compounds and chemosystematics of the feverfew in this group of BAS has not been conducted before. \u0000The aim of the research was to obtain the volatile oil from the feverfew herb, studying of the component composition, an identification of compounds, that can be used for chemosystematics of the genus and establishing of the pharmacological activity according to the chemical content of volatile oil. \u0000Materials and methods. The object of research was the samples of the feverfew herb grown and collected in the period of its mass flowering. The volatile oil obtained by steam distillation from the feverfew herb was studied using gas chromatography–mass spectrometry. \u0000Results. The comparative characteristic of the representatives of the genus Tanacetum according to chemosystematic features was carried out. As a result of the research of the volatile oil 44 compounds were found, from which 40 were identified. According to the research, the raw material contained 34.71 % of camphor, this is a typical feature of all species of the genus Tanacetum. Fenchyl acetate was identified in a high enough content – 7,44 % in the domestic raw material, but this compound was not identified in the foreign samples. Chrysanthenyl acetate is accumulated in representatives of the genus Tanacetum in the form of a cis or trans isomer. In our study, the content of trans-chrysanthene acetate was 23.30 %. In the domestic raw materials, monoterpenes – α- and β- thujone – were not identified, which are associated with the toxicity of the raw material. \u0000Conclusions. In the volatile oil 44 compounds were found, from which 40 were identified. Monoterpenes prevailed among terpenes, namely camphor, trans-chrysanthenyl acetate and fenchyl acetate, which are typical and can be used for chemosystematic issues of the genus Tanacetum. \u0000The identified compounds require anti-inflammatory, antiseptic, antispasmodic, analgesic activities of the volatile oil, therefore creation of the medicinal herbal remedy based on the volatile oil of the feverfew herb is prospective.","PeriodicalId":286770,"journal":{"name":"Food Chemistry eJournal","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121986663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major objective of the study was to critically review the dairy cow industry in the world. Total 18 articles were downloaded from the net and many times were read and analyzed the situation about dairy cow industry and draw the results. The result indicates that cow dairy industry is very important industry in the world which provides milk, meat and manure to the countries of the world. Mostly majority byproducts are exported to other countries of the world. Fodders play great role in milk production. The developed countries provide balance food to their cow while developing countries foods are imbalances which give less milk in the developing countries of the world. The main thing is the fund. The developing countries budget is very weak and they always demand from IMF and World Bank for their deficit budget fulfillment. So it is observed, that their everything is very weak and they always depend on the developed countries. The developed countries interfere in their country matter and policy, so because they always poor and their country institution are very weak and their research are very weak and they cannot produced quality students for their countries to do good research in dairy industry. So the study shows that fund is necessary for the development of a country and without good fund the development of the country is impossible. Through research new breeds are produced which play great role for milk production. It was also observed that in the world that Friesian cow give 60 litters milk in the lactation period while this characteristic is not in Achay breed in Pakistan to give more milk. Most milk is produced during the period between early-to-mid spring and midwinter, which largely connected with the grass growing season in the world. The review further explains that over excess of more feed by dairy cow not increase the protein and fat percentage in the cow milk while the over excess food discharged in the urine and dung which latter on increase the methane gas in the environment which play great role in climate change and depleting the ozone layer. It was also diagnosed that grazing cow health is better than the non grazing cow in the world. So more space is required for rearing of cow herds in the world. Similarly it was also reviewed that A1 β casine in cow milk cause the coronary heart disease and Type-I diabetes in the world. New Zealand have set up, testing laboratories in his country for checking of A1 β casine because it is dangerous for the health while few scientist go against this statement. They told that CHD and Type-I diabetes have no relationship with A1 β casine. Similarly day by day the production of crop land is decreasing in the world due to house construction and road development and population in the world.

Smallholder farmers face a number of barriers to improving the quality and safety of their produce, including a lack of awareness about safety and quality standards, the cost of equipment required to improve these, and the failure of premium prices to pass through to farmers. In this paper, we examine how lifting each of these barriers affects Ghanaian groundnut farmers’ adoption of post-harvest practices that reduce aflatoxin contamination. Aflatoxins are carcinogenic secondary metabolites of certain molds, which cause serious health problems including liver cancer. Common in groundnuts and maize, staple foods in much of Africa, aflatoxins pose a major threat to food safety and hinder the development of local agricultural value chains and export markets. Aflatoxin contamination can be substantially reduced through low-tech, low-cost post-harvest practices. We conducted a randomized control trial in northern Ghana with 1,005 farmers over the course of two seasons to test the imapct of three interventions to improve post harvest practices and reduce aflatoxin levels: (1) farmer training on aflatoxin and its prevention, (2) distribution of free drying tarps, and (3) a price premium for groundnuts found to comply with the local aflatoxin regulation. Training farmers substantially improves post-harvest practices. Tarp receipt further improves some practices, particularly with regards to drying surface. Surprisingly, we find that the price premium had little effect on reported or observed practices, and few farmers even sold nuts at this premium despite achieving compliance. Relative to training alone, tarp distribution reduced afaltoxin contamination by approximately 50 percent in the region and year when background levels were highest. The market premium also reduced aflatoxin levels, although to a lesser extent.","PeriodicalId":286770,"journal":{"name":"Food Chemistry eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129333494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This policy brief addresses critical issues binding groundnut oil sector inefficiency and international competitiveness. With the widening gap between demand and supply of edible oils in India, policy action is imperative not only to arrest surging imports of edible oils but also to benefit both producers and consumers in terms of broader employment generation and decentralized rural industrialization. Specific policy implications are highlighted in this policy brief, which encompass: a) the harnessing of improved varieties with attributes like drought tolerance, high oil content, high productivity for large scale seed multiplication/distribution by both public and private agencies; b) viable village seed banks and seed networks through cycles of rabi (postrainy) season seed multiplication to meet the seed requirements of kharif (rainy season) and vice versa; c) low-cost technologies to increase profitability and reduce risk; d) oilseed clusters to facilitate scale economies and capacity utilization in processing units; and e) capital subsidies to accelerate technological upgrading to shed inefficiency in the processing sector. The expected gains in efficiency in both production and processing of oilseeds are expected to produce measurable producer and consumer benefits, which will justify proposed non-market distorted subsidy for both seeds and technological upgrading in the processing sector.","PeriodicalId":286770,"journal":{"name":"Food Chemistry eJournal","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127481141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different PGPR concentrations (0%, 3%, 4%, and 5%), sonication times (4 min and 6 min), and power (160 W and 200 W, corresponding to 40% and 50% of power amplitude in relation to the nominal power of the ultrasonic probe) were used. PGPR proved to be effective in the kinetic stability of the emulsions, for an optimal concentration of 4%. The findings showed that the ultrasound treatments improved the emulsifying properties at different levels. The treatment W/O-200W-4min showed lower particle size (3.15 ± 1.86 µm) and polydispersity index. The US treatments increased the viscosity of the emulsions. The ultrasound treatment affected the anthocyanins and phenolic compounds levels, with values of 119-113 mg malvidin-3,5-diglycoside /100 g, and 287-205 mg GAE / 100g on a dry weight basis, respectively. The antioxidant activity of the emulsions was also affected by the US, with values of 75-68%. FTIR analysis indicated no changes in the molecular structure of the palm oil and palm fat after ultrasonication. The US-treated emulsions had a longer half-life (49-56 days) when compared to the control treatment (41 days). The accelerated stability test of the emulsions at 65°C for 120 hours showed that the US increased the stability, provided a controlled release of anthocyanins in the grape peel extract, and reduced the lipid oxidation and the color changes during storage, which is desirable for its application in food systems.","PeriodicalId":286770,"journal":{"name":"Food Chemistry eJournal","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115592481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
