A total of 164 samples comprising of different leafy green vegetables (8 basils, 15 dills, 20 garden cresses, 16 kales, 12 lettuces, 19 mints, 19 parsleys, 18 purslanes, 1 radish, 20 rockets, 14 scallions and 2 spinaches) were randomly collected from nearby agricultural fields in the close vicinity of Ankara Stream over an 8-month period between April 2007 and November 2007. Samples were examined for Salmonella and L. monocytogenes using ISO methods with immunomagnetic separation (IMS) and then polymerase chain reaction (PCR). No Salmonella and L. monocytogenes was detected from the 25-g radish, spinach and scallion samples tested. However, 23 samples (1 basil, 2 dills, 1 garden cress, 1 kale, 2 lettuces, 4 mints, 3 parsleys, 5 purslanes and 4 rockets) were positive for Salmonella and 14 samples (3 basils, 1 dill, 1 garden cress, 2 kales, 1 lettuce, 1 mint, 2 parsleys, 1 purslane and 2 rockets) were positive for L. monocytogenes. Overall, important contamination of leafy green vegetables by Salmonella and L. monocytogenes was observed. Therefore, this study will draw attention to the production of freshly consumed leafy green vegetables and so will aid in the development of control measures for these pathogens before harvesting and will highlight the importance of their intake which may cause a communicable disease and so pose a serious threat to both environment and human health.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"55 1","pages":"275-279"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80203101","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 study also explored the factors influencing the degree of consumer preferences. The data were obtained from a survey of 803 randomly selected consumers from the five most developed regions of Turkey (Marmara, Central Anatolia, Aegean, Mediterranean and Black Sea), as well as the five most developed cities (Istanbul, Ankara, Izmir, Adana and Bolu) within the defined geographic regions. This study took place in two stages. In the first stage, fuzzy pair-wise comparison (FPC) was applied to calculate a measure of preferences. Five types of venues for the purchase of organic fruits and vegetables, local market, greengrocers, supermarkets/hypermarkets, web-based retailers (the internet) and specialized stores were suggested to consumers. The purchase places were ranked from most to least preferable depending on preference measures obtained from FPC. The results show that the most important venues for the purchase of these items are local markets and supermarkets/hypermarkets. The existing marketing channel via specialized stores is not a convenient marketing approach for Turkish consumers. The consumer preferences from the first stage were regressed upon the consumer-specific variables by using a Tobit model in the second stage. Preferences regarding places to purchase organic fruits and vegetables are mainly influenced by gender, age, education, income, family size, frequency of purchasing organic fruits and vegetables and regional differences. Policy makers dealing with agricultural marketing should consider differences in consumer preferences among regions and economical and demographic attributes of consumers for determining an efficient marketing channel.","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"69 1","pages":"144-149"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86400276","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}

Xylan was hydrolyzed using Trichoderma longibrachiatum xylanase preparation, and the effects of pH, temperature, hydrolysis period, substrate and enzyme concentrations on the xylooligosaccharide yield and degree of polymerization were investigated. It was found that these three agricultural wastes contained different amounts of xylan, cellulose and lignin and the xylan obtained from these sources contained different amounts of sugar and uronic acid. The xylan from WS had the highest amount of arabinose while the other xylans mainly had xylose and small amount of glucose. Trichoderma longibrachiatum xylanase hydrolyzed highly branched wheat straw xylan (WSX) better than cotton stalk xylan (CSX) and tobacco stalk xylan (TSX) under favorable conditions ( reaction time of 8 h at pH 4.6 and 50oC). The TLC analysis of the hydrolysis products indicated that the hydrolysis product of T. longibrachiatum xylanase contained different amounts of oligosaccharides (X2, X3, X4, X5, X6, X7) with some monosaccharides. Regardless of the structural differences of the xylan types presented in this paper, all xylans generated XO with different degree of polymerization (DP).","PeriodicalId":15809,"journal":{"name":"Journal of Food Agriculture & Environment","volume":"50 1","pages":"70-74"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85751643","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}

Three mulch types – plastic mulch, grass mulch (Panicum maximum) and wood (Tectonia grandis) shavings were compared with hand weeding and no weeding control in a randomized complete block experiment with three replications. Okra growth and yield were significantly influenced by the treatments (P<0.05). Plants under plastic and grass mulches had bigger leaves and stems, as well as higher number of branches compared to those of wood shavings mulch and weedy control plots. The plants were also significantly taller and were similar to plants under the hand weeding control in these parameters (P<0.05). Plants under the weedy control were the poorest in their growth attributes. The highest yield of 12,135 kg/ha was obtained under plastic mulch, which was significantly higher than all those other treatments (P<0.05). Yields from grass mulch (6,703 kg/ha) were similar to that of the hand weeding control (6,976 kg/ha). However, these were significantly higher than those of wood shavings mulch (5,301 kg/ha).

A basis for processing decision making has been provided using exploratory research techniques to review tomato consumption, market segmentation and structure, production surpluses, prices and buying process of fresh and paste tomato. Fresh tomato surplus projects at 23,000 to 118,000 t p a (2000-2007) though actual glut period is short, occurring from February to March when 92 percent of farmers harvest, and traders use hedging tactics to avoid tomato spoiling on their hand. With the short glut period, large-scale processing requires planning and investment in semi- processed or cold storage facility, integrated project with cultivation of tomato variety suitable for harsh lean season climatic conditions and production staggering to prolong harvesting. Projected paste from surplus produce exceeds catchments area market, yet access is in competition with established brands such as Salsa, La bianca, Bonito, Tomaroma and Obaapa. Processing could target a paste market of 2,000-3,000 t, requiring l6,470 t fresh tomato, at a processing capacity of 2.3 t per hour, 24 hour-day and for 300 days p a, with plans for future expansion.
