Often, their results will not be used and may hardly contribute to science or technology. This is all the more surprising, since work done in the past hardly ever provides final answers, and therefore leaves questions unanswered, questions that could perhaps not be studied with the tools available at the time but that could be tackled nowadays. In the present series of articles I will discuss a number of subjects that in my opinion warrant research and I will suggest how this research can be approached.</p><p>The water degumming process has been in industrial use for almost a century. Some insight was gained during the last century, but research was abandoned when it reached the limits of the analytical capabilities of the time. Consequently, there are many open questions concerning the composition of compounds containing phosphorus, how much of the acid value should be attributed to FFA, how the triglyceride content of the gums can be controlled and how the industrial process can be optimised with respect to the predictability of process performance, product quality and cost.</p>","PeriodicalId":18083,"journal":{"name":"Lipid Technology","volume":"28 10-11","pages":"165-167"},"PeriodicalIF":0.0,"publicationDate":"2016-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/lite.201600043","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88511921","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}

It serves as the main component of the Mediterranean diet and one of the most valuable products of the agro-food industry, not only for its taste, but also for its high nutritional value. As it is considered the lipid constituent of the olive fruits, it is composed mainly of triglycerides and phenolics. Authentication and traceability of extra virgin olive oil is a challenging research task due to the complexity of fraudulent practices. Various chemical and biochemical techniques have been developed for determining the authenticity of olive oil. Olive oil DNA-based analyses have gained attention in recent years, due to high specificity, sensitivity and reliability. DNA analyses have very high discriminating power because ultimately the unique identity of a variety or species is to a great extent genetically dependent. Polymorphisms are genetic variations which refer to the variation in populations or species. Molecular markers provide information on genetic variations and are valuable tools to determine olive oil authenticity. Molecular markers such as SNPs, microsatellites, SCARs and AFLPs have been used for the identification of the varietal origin of olive oils. This feature provides an overview of the current trends and critical issues on DNA-targeted approaches used for traceability and authenticity of olive oil.</p>","PeriodicalId":18083,"journal":{"name":"Lipid Technology","volume":"28 10-11","pages":"173-176"},"PeriodicalIF":0.0,"publicationDate":"2016-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/lite.201600048","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89581854","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}
