RESULTS The results showed that meat species were accurately determined in all combinations by multiplex-PCR, and the sensitivity of this method was 0.001 ng, rendering this technique open to and suitable for use in industrial meat products. It is concluded that more fraud is seen in lower percentage industrial meat products than in higher percentage ones. There was also more fraud found in processed products than in raw ones.

The TL was increased (8.21% to 15.95%, g/100g) by increasing the NaCl % (from 10% to 30%) coupled with the depletion of KNO3 level (from 2.5% to 1%) in culture medium. High lipid content (15.95%) was obtained in S2+ 2N culture, this lipid showed physical (density, viscosity and average molecular weight) and chemical (iodine, acid, saponification and peroxide values) properties suitable for biodiesel production.</p><p><strong>Results: </strong>The fatty acid methyl esters (FAME, biodiesel) prepared by trans-esterifiction reaction under acidic condition were mainly composed of saturated (50.33%), monounsaturated (MUFA, 36.12%) and polyunsaturated (13.55%) esters. C-18:1 was found to be the main MUFA, representing 25.76% of total FAME. On the other hand, the values of some critical of physiochemical parameter (density, kinematic viscosity, iodine value, acid value and oxidation stability) of biodiesel were found to meet the standards for a high quality biodiesel.</p><p><strong>Conclusion: </strong>Hence, U. lactuta could be serving as a valuable renewable biomass of oil for biodiesel production. There are recent patents also suggesting use of oil of U. lactuta marine biomass for biodiesel production.</p>","PeriodicalId":21061,"journal":{"name":"Recent patents on food, nutrition & agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35051864","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}
