Land application of olive mill wastewater (OMW) is considered a promising low-cost practice for olive-oil producing countries. The objectives of this work were to investigate: (i) OMW treatment potential of a land treatment system (LTS), planted with a E. camaldulensis species, regarding N, P, C, and phenols; (ii) the effects of OMW on chemical properties of soil and soil solution...

According to the International Olive Oil Council, refined olive oil is the olive oil obtained from olive oils by refining methods that do not lead to alterations in the initial glyceridic structure.It has a free acidity, expressed as oleic acid, of no more than 0.3 grams per 100 grams (0.3%) and its other characteristics correspond to those fixed for this category in the IOOC standards.

Oil samples were subjected to chemical analyses: free acidity, peroxide value, ultraviolet light absorption K232 and K270, total polyphenols, antioxidant capacity, volatile compounds and olfactory characteristics by electronic nose.

Two monovarietal extra olive oils from Arbequina and Picual cultivars were subjected to heating at 180 degrees C for 36 h. Oxidation progress was monitored by measuring oil quality changes (peroxide value and conjugated dienes and trienes), fatty acid composition, and minor compound content. …

Triolein is found in cacao butter and accounts for 70-80% of olive oil. If released to air, an estimated vapor pressure range of 5X10-5 mm Hg to 1.1X10-9 mm Hg at 25 °C indicates triolein may exist in both the vapor and particulate phases in the atmosphere.

Purpose: Nutritional quality and oxidation stability are two main factors in the evaluation of edible oils. Oils in their pure form do not have an ideal fatty acid composition or suitable oxidative stability during processing or storage. Methods: This study was designed to evaluate the chemical, nutritional and rheological properties of oil mixtures in three ratios of olive: sesame: linseed ...

The foodstuffs that contain the highest concentrations are grains and rice, soya beans, eggs, nuts, olive oil, green beans and oysters. After absorption in the human body manganese will be transported through the blood to the liver, the kidneys, the pancreas and the endocrine glands.

Therefore, the aim of the present study was the chemical analysis of the oil derived from these seeds and its comparison with well-known vegetable oils, such as sesame, flaxseed and extra olive oils, as well as the analysis of the seedcake, which is the residue of cold-pressed seed-oil extraction, considered a by-product.

From a chemical point of view, we can identify in the olive oil two fractions, depending on the behavior in the presence of heating and strong alkaline solutions (concentrated solutions of KOH or NaOH):. the saponifiable fraction, which …

Olive oil is a vegetable oil.It is made by getting the juice of the fruits of the olive tree.These are called olives.The oil is used in cooking, as well as cosmetics, traditional medicine, and as a fuel for oil lamps.Refined olive oil uses heat and chemicals to get the fat out of the olives.

Erucic Acid is a monounsaturated very long-chain fatty acid with a 22- carbon backbone and a single double bond originating from the 9th position from the methyl end, with the double bond in the cis- configuration. NCI Thesaurus (NCIt) Erucic acid is a docosenoic acid having a cis- double bond at C-13.

Vegetable oils are for the most part refined before consumption, refining comprising a series of steps designed to produce a bland, stable oil. Refined oils may be modified in order to change their physical properties. , i.e., unrefined, olive oil plays an important part in the market for vegetable oils.

Olive oil is a liquid fat obtained from olives (the fruit of Olea europaea; family Oleaceae), a traditional tree crop of the Mediterranean Basin, produced by pressing whole olives and extracting the oil.It is commonly used in cooking, for frying foods or as a salad dressing.It is also used in cosmetics, pharmaceuticals, and soaps, and as a fuel for traditional oil …

An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and surface active.Most oils are unsaturated lipids that are liquid at room temperature.

Good plant sources of omega-3 fats include flax seeds, walnuts, and canola or soybean oil. Higher blood omega-3 fats are associated with lower risk of premature death among older adults, according to a study by HSPH faculty. Read more about omega-3 fats in our Ask the Expert with Dr. Frank Sacks.

2. Chemical Composition of Olive Oil. The chemical composition of olive oil varies depending on the extraction technology that is applied in order to obtain oil form the fruits (Figure 1).The process of extraction of olive oil depends on crushing olives and then separating the oil from the fruit pulp under elevated pressure.

the secoiridoid oleuropein must be highlighted [1,8]. Besides, olive oil is also a source of pigments like carotenoids [3]. Phenolic compounds are known for their biological properties. In particular, these olive oil compounds have shown potential as antioxidant, anti-inflammatory and antimicrobial agents [9].

The Olive tree (Olea europaea L.), a native of the Mediterranean basin and parts of Asia, is now widely cultivated in many other parts of the world for production of olive oil and table olives.Olive is a rich source of valuable nutrients and bioactives of medicinal and therapeutic interest. Olive fruit contains appreciable concentration, 1–3% of fresh pulp weight, of hydrophilic (phenolic ...

The oil chemical composition and sensory profile of four Palestinian olive varieties (Nabali Baladi, Nabali Mohassan, Souri and K18) were characterized in 2010 throughout an in situ evaluation.
