Native starch in general and particularly sweet potato starch characteristics have several functional features and applications in biomedicine as well as in the food industry. Modified starch is expected to enhance such characteristics as discussed in this review. For instance, due to the polymeric and branching nature of starch; the starch is usually less soluble, absorbs less water and oil, and shows a strong ability to bind to iodine. Also, native starches have significantly lower digestibility values under enzymatic treatment. Starch modifications, therefore are designed to enhance one or more of the above-mentioned limitations; thereby, modification of starch can alter the physicochemical characteristics of the native starch to improve its functional characteristic. \u0000Starches can be modified using physical methods (annealing, heat moisture treatment, pre-gelatinization, and other non-thermal processes), chemical methods (etherification, acetylation, acid modification, cationic linking, esterification, cross-linking, and oxidation), enzymatic modification methods, genetic alteration process or combination of them.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79148486","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}

Understanding the profitability of these crops can enhance farmers’ decisions to grow them. Therefore, this study investigated cocoyam production profitability, factors responsible for its profitability, and the constraints faced in cocoyam production in Cross River State, Nigeria. Data collected primarily with the use of questionnaires were analysed with descriptive statistics, cost and return analysis, multiple regression and the Likert rating scale. The results revealed that the majority of cocoyam farmers were male, married, in their economically active age and operated on a small scale. Cocoyam production was a profitable venture as the farmers had a gross margin of N175, 822.45 (USD 428.04) per hectare of cultivated land with an operating ratio of 0.24 and a return on capital invested of 3.17. The factors that influenced the profitability of cocoyam production were education, household size, farm size, farm output, cooperative membership, access to credit and annual income. The major constraints faced in cocoyam production were inadequate access to credit, poor government support, high cost of inputs and poor storage facilities. To enhance cocoyam profitability, the study recommends the provision of farm inputs and financial support to inform of credit or grants to the farmers. This would not only increase their profit but also enhance the decision to increase production which will increase food availability and, in turn, reduce the problem of food insecurity.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"98 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72631454","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}

Olive fruits of cultivars \"Ayvalik\", \"Grossa de Spain\" and \"Nabali\" were harvested on October 20 and November 13, 2017, using hand and mechanical (by combs) harvesting methods. Olive fruits were pressed then, olive oil samples were analyzed for acidity, peroxide value, refractive index, olive oil percentage, and sensory properties. The results showed that the harvesting method did not significantly affect oil quantity and chemical analysis, but affected sensory properties of olive oil, where the harvesting method by hand gave the highest (fruity, bitter, and pungent) and the lowest negative attributes (fusty, musty and rancid). Furthermore, as ripening progressed, there was an increase in olive oil percentage, oil acidity and peroxide value. The positive attributes (fruity, bitter and pungent) were significantly decreased while negative attributes (fusty, musty and rancid) were increased as ripening progressed. On the contrary, the refractive index (at 25°C) remains almost constant. The response of olive cultivars to harvesting was inconstant and did not respond similarly, \"Ayvalik\" had the highest acidity and peroxide value, while \"Grossa de Spain\" had the highest oil percentage. In addition, \"Nabali\" had the highest positive attributes. The lowest acidity, peroxide value and negative attributes were obtained for \"Nabali\". The result proved that olive cultivars and harvesting date and method combine together to influence acidity, peroxide value and sensory properties (fusty, musty, rancid, fruity, and bitter) of olive oil.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81534403","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}

They are the second largest grown vegetable in both terms of production and consumption. Demand for tomatoes has been increasing recently due to their high content of nutritionally- acclaimed carotenoids, fibers, vitamins, and minerals, hence it has been the subject of numerous studies both in the laboratory and under field conditions. The quality of a tomato is determined by internal and external attributes, internal such as texture, sweetness, acidity, aroma, flavor, and nutritional value, and external which are appearance factors such as color, shape, size, and firmness. This review aims to investigate the chemical composition of tomato fruits and how they influence their quality. The findings of chemical composition (minor and major) components that were reported by many researchers are reviewed in this article.  Also, this review focuses on the effect of tomato variety on the chemical composition of this fruit, and how these components are varied during the ripening process.

It contains more than 1000 biologically active compounds such as caffeine, diterpene alcohols, and chlorogenic acid. The effect of coffee on health is controversial depending on the type and the amount consumed of coffee. This review was prepared to clarify the effect of different preparation methods on coffee lipids content, as well as to study the effect of consumption of coffee prepared by different methods on body lipids profile. Coffee can be prepared by several methods, but the most two popular methods are brew and espresso. Coffee lipids which are called diterpenoid alcohols (cafestol and kahweol) can influence the body’s cholesterol level. The content of coffee lipids can be altered due to the methods of coffee preparation. Cafestol remains in the beverage of coffee when hot water is directly poured onto powdered coffee, when well-milled coffee is boiled in water a few times or when the metal filter is used instead of a paper filter, like in French Press. However, to good fortune, most of them are retained by the paper filter, which substantially reduces the cholesterol-raising effects potentially associated with coffee through consuming filtered coffee. Diterpenoids in unfiltered coffee cause an elevation of total cholesterol TC and low-density lipoprotein LDL cholesterol levels, whereas lowering the high-density lipoprotein HDL cholesterol levels in the body. However, consumption of filtered coffee slightly affects serum cholesterol levels. Also, the results of other studies revealed that the roasting degree of coffee is not related to an increase in the total cholesterol and the LDL cholesterol concentrations, but can be related to an increase in HDL cholesterol level after consumption of medium roasting MR coffee.","PeriodicalId":14707,"journal":{"name":"Jordan Journal of Agricultural Sciences","volume":"693 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77393029","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 was based on the collection of preliminary data via interview, using the questionnaire tool, and took a random sample of fruit tree farms from a total area of 3,822 dunums constituting 5.5% of the total area planted with fruit trees. This area is exploited by 70 growers distributed in the whole province.  The results of the present study indicated that 88% of the respondents are educated and approximately 65.8% of growers have secondary and university graduates. Respondents used regularly the IPM was only 7.1%. The study showed that the most important diseases affecting fruit trees were fungal diseases, especially powdery mildew, leaves curl, and eyes of peacocks, which are considered the most dangerous diseases of trees limiting production quantities and more expensive as a result of repeated application of pesticides. The five-grade Lekert scale was used for evaluation; \"always\" was given five degrees and \"never\" represent one degree for the positive answers, while the scoring was reversible to the negative responses; \"never\" was given one score, and \"always \"was given five degrees. This scale covered twenty-four actions done by the growers to protect their trees. Alpha Kronbach Coefficient was 0.78, reflecting the internal consistency of the study scale. In the current study descriptive statistics methods such as repetitions, percentages and arithmetic averages, and standard deviation were used to analyze the data statistically. According to Leckert scale, items 5-21 gave a mathematical average of 1.96-3.5, and 35.7% of the respondents know what the concept of integrated control is? and this shows that the respondents did not use any of the methods of IPM. 35.7% of the information about IPM is obtained by the farmer from the Ministry of Agriculture, the Colleges of Agriculture, and the NNARC.
