Extraction Methods of Essential Oils From Herbs and Spices

2017

International audience; This chapter describes both conventional and non‐conventional extraction methods of essential oils (EOs) from herbs and spices. Although hydrodistillation, steam distillation and solvent extraction are the most applied methods, several non‐conventional technologies have been evaluated, especially in respect to EO recovery, and a great potential has been attributed to these non‐conventional methods. For instance, ultrasound, microwave, supercritical fluid, pulsed electric fields, ohmic‐heating and microwave (MW) extraction techniques applied alone or combined with other techniques are potent tools to obtain EOs in a 'green' way from natural resources such as aromatic …

The state-of-the-art of collaborative technologies for initial vocational education : a systematic literature review

Effect of dietary omega-3 and omega-6 fatty acids on IOP elevation, electroretinographic changes and retinal ganglion cell loss in a laser-induced ra…

2008

International audience; Purpose:To test the efficacy of dietary omega-3 and omega-6 fatty acids in a rat model of glaucoma induced by laser photocoagulation.Methods:Male Sprague Dawley rats were fed for 3 months with a diet containing either: 1) 17% of omega-3 fatty acids (10% EPA + 7% DHA), 2) 10% of omega-6 fatty acids (as GLA), or 3) a combination of both omega-3 and omega-6 fatty acids (10% EPA + 7% DHA + 10% GLA), by comparison with a control group of animals fed with a standard diet deprived of EPA, DHA and GLA (n=10 in each group). After 3 months of diet, glaucoma was induced in one eye of each animal by laser photocoagulation (532nm) of the episcleral veins, the trabeculum and the l…

Towards sustainable farming practices and food security: study about vulnerability of Finnish farms

2017

The aim of this paper is to discuss food security in the context of sustainable farming practices in Finland. There are two research questions: 1) How are the Finnish farms vulnerable from the viewpoint of food security? 2) How could they increase their resilience for guaranteeing food security in the future? The paper is based on a qualitative study for which 15 Finnish food system specialists were interviewed in 2015. According to the results, three types of vulnerabilities are discovered: 1) market vulnerabilities, 2) continuity of farms, and 3) environment changes. For reducing vulnerabilities, the re-evaluation of policy instruments is needed. At the same time, new knowledge and skills…
