Moisture contents of olive fruits decreased from 36.64% to 23.86%, both salt concentration and firmness increased to 9.35 g NaCI/100 g and 51.6% respectively. Total phenols of olive fruits changed from 1714.5 mg GAE/kg to 451.4 mg GAE/kg and radical scavenging activity (DPPH %) decreased from 91.48% to 32.14% respectively. L*, a* and b* values of Gemlik olives were decreased during fermentation. There was a close relationship among physicochemical parameters of Gemlik olives in mathematically. In order to model this mathematical relation, Vandermonde matrix based 3th degree polynomial equations was used because it gave best model fits for the data of physical and chemical parameters of olive fruits. On the other hand, according to the results of sensory evaluation, the attributes of saltness and crispiness were highly scored (7.21-7.34) but the sensory scores of astringency and bitterness were evaluated from 4.56 to 5.61 by participants. The physico-chemical characteristic changes during the fermentation of Gemlik olives subjected to dry salting method for producing table olives were modeled and suggested with the determined physico-chemical evaluation scores to future studies.","PeriodicalId":68173,"journal":{"name":"食品科学与工程:英文版(美国)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47259879","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}

There is an over-whelming demand for high quality cassava flour (HQCF) by Bakeries, beverage industry, paper board and composite end markets. The end market for HQCF dictates on its quality attributes and rewards for its quality in terms of price offered within their minimum standards. However, obtaining sustainable amounts of HQCF for these markets calls for devoted efforts. Limited types of HQCF processing technologies exist and if they exist, their efficiency, costs and sustainability are not well understood. We evaluated high quality cassava drying technologies in Northern and Eastern Uganda in two years using naturally ventilated wooden screen solar drying structures and open air sun drying structures. Naturally ventilated wooden screen solar dryers produced clean dry high quality cassava chips free off insect and bird contamination and caused faster drying to less than 14.3% MC in 1.5 hours than open outside drying conditions. We recommend naturally ventilated wooden screen solar dryers for small and medium cassava processors during dry and rainy season. Half tone to one tone cassava chips dryers per day drying unit can cost one 2,258-4,338 USD to make it functional. Also open outside raised metallic racks with black surface can give good results on a good sunny day especially for starters on small scale basis. A small durable unit of 150 kilograms per day can be made with 500 USD.","PeriodicalId":68173,"journal":{"name":"食品科学与工程:英文版(美国)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47832386","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 aim of this prospective study was to estimate TFAs the placental transfer of TFAs to the foetus cord blood and cord tissues in France. Material: TFAs consumption was measured in 59 mother-foetus couples. TFAs transferring across the placenta were estimated by comparative measurement (Capillary Gaz Chromatography) of TFAs in mother’s blood lipids (n = 59), cord blood lipids and cord tissue plasma lipids (n = 25) cord red blood tissue (n = 25) and umbilical vessels (n = 15). Results-Discussion: TFA deposition in cord blood is 0.58% slightly lower than mother level. TFAs incorporation in total lips of cord show selectivity of transfer with lower 18:1 t in cord blood and preferential transfer of diene 18:2 tc in cord blood. There is competition between the 18:2 tc in cholesterol esters (CE) with the linolenic acid and a negative correlation in PLT of arterial tissues with the 18:2 tc and C20:4 n-6 or arachidonic acid (AA), then there is the same competition in PE of venous tissue. But there is no effect on growth in our population of term newborn. Conclusions: Our results confirm the placental TFAs transfer, a better incorporation in the fetus CE; we demonstrated a selective transfer for the 18:2 9 trans 12 cis (18:2 tc) and a negative correlation (r = -0.76) with the linoleic acid and AA (r = 0.98). This competition, and the presence of these TFAs in cord tissues, even at a low TFAs consumption, remind us to be a potential risk for the fetus concerning EFA metabolism and growth.","PeriodicalId":68173,"journal":{"name":"食品科学与工程:英文版(美国)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45408403","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}

Although mango is being grown in more than hundred countries none of them is comparable to Pakistani mango which is famous for its unique taste all over the world. Pakistan’s per hectare production is much lower than its potential. The purpose of this study was to assess those factors which are preventing mango growers from getting its potential yield. For this major mango producing area, Muzzaffargarh was selected. The 110 randomly selected farmers were interviewed with a well-designed questionnaire. The mango growers were divided into three categories on the basis of landholding. The Cobb-Douglas model was used to assess the effect of different factors on the productivity. The education level and age of large farmers was found highest among small and medium farmers. Large farmers were enjoying significant high profit per acre with US$519.58 as compared to medium farmers (US$454.15) and small farmers (US$395.10). The independent variables were explaining almost 89 percent variation in productivity of mango. The significant positive effect of orchard experience, access to extension services, the quantity of NPK, quantity of pesticides and labour cost was found. The age and intercropping practices in mango orchard had a significant negative effect on mango production. Credit facilities must be made available at lower interest rate and the range of extension services must be enhanced to increase the productivity of mango.","PeriodicalId":68173,"journal":{"name":"食品科学与工程:英文版(美国)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46250661","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}

In order to understand its value to the EU potato industry, a stakeholder survey was conducted to understand the implications for P. infestans control and the impact on EU potato production if mancozeb was not available. In total, 319 growers and advisers were surveyed in 8 countries: France, Germany, Ireland, Netherlands, Greece, Italy, Spain and the UK, to determine how they use mancozeb, potential alternative control strategies and the implications of withdrawal. This study demonstrates that mancozeb is a widely used and cost-effective multisite active ingredient, which is a highly valued means of control for P. infestans. Based on the survey results, a loss of mancozeb would lead to a reduction in gross margin for potato producers in these countries of €87 million to €507 million depending on the level of P. infestans pressure. The combined impact of high cost of production and increased risks is likely to lead to reductions in the availability of EU potatoes and increased costs to consumers. In addition, an assessment was completed to determine the impact of mancozeb withdrawal on fungicide resistance development to single-site acting fungicides, finding that the loss of a multi-site active ingredient like mancozeb would severely compromise fungicide resistance management.","PeriodicalId":68173,"journal":{"name":"食品科学与工程:英文版(美国)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43971676","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}
