2.1.2 Limitations of lime essential oil
Lime essential oil (EO) is widely used in large industrial application for its energizing, fresh and cheerful aroma due to its functional compounds (Burt, 2004). Due to their aromatic properties and antimicrobial activities, they are of great interest as food additives for pharmaceutical, cosmetics and food industries (Simas et al., 2017). However, despite the potential applications of lime essential oil as functional components in foods and beverages, the utilization of lime essential oils is often limited because of their relatively low water solubility (Chang et al., 2012). This can be explained by the reason that essential oil are generally the mixtures of hundreds of lipophilic aroma compounds including lipophilic terpenoids, phenylpropanoids and short-chain aliphatic hydrocarbon derivatives, making it to be immiscible when added to water (Kubeczka, 1979).

Furthermore, terpenes which is the most characteristic constituents of lime essential oil tends to be both volatile and thermolabile and may be easily oxidized or hydrolysed under different conditions such as during production or unstable storage conditions (Scott, 2005). For example, the major flavor components of lime oil such as citral which is a naturally occurring aliphatic aldehyde of the terpene series and limonene which is classified as cyclic terpenes can easily undergo chemical degradation which will lead to the loss of flavor and the formation of undesirable off-flavours (Djordjevic et al.,
Esters are defined as molecules consisting of a carbonyl group which is adjacent to an ether linkage. They are polar molecules which are less polar than alcohols but more so than ethers, due to their degree of hydrogen bonding ability. Most often derived from reacting an alcohol with a carboxylic acid, esters are a unique, ubiquitous class of compounds with many useful applications in both natural and industrial processes 1. For example, within mammals, esters are used in triglycerides and other lipids as they are the main functional group attacking fatty acids to the glycerol chain 2. A unique property of esters is their tendency to give off distinct aromas such as the scent of apples (Ethyl caprylate) and bananas (Isoamyl acetate). This is of a unique importance especially in industries that utilize flavors and aromas such as the tobacco, candy and alcohol industry. Consistent research is conducted in order to enhance and increase the effectiveness of esters in these products 3.
With all the fuss beauty experts are making about Argan oil and Maracuja oil. You probably had heard both of these oils’ wonders.

A man has an incurable chronic illness and receives 8 blood transfusions, and is told that he will have to have huge sections of his intestines removed if he doesn 't not improve, and only after consuming some seed oils he actually feels healthier than he did before he got sick. Sounds like something out of a fiction novel, but it is an actual story of an Olympian! Is a certain combination of seed oils actually that beneficial for health? This PanaSeeda Five Seed Oil Blend review will take a look at a specific combination that helped a man go from death bed to pure health.
Before you go on to try any other type of oil (or really any other type of food), cleanse your palate with water and slices of green apple
Citrus fruit are not just used for fresh fruit and juice. It has many other uses. One is in jellies and in other preserves. Preserves include marmalades and crystallized fruits. A by-product of citrus production is ...
What is aromatherapy? In an article titled “Phytotherapy Research” by Amr Edris, he describes aromatherapy as, “The use of essential oils and their volatile constituents are widely to prevent and treat human disease.” Aromatherapy is said to be an alternate form of medicine that uses essential oils, which are made up of volatile plant materials. With these essential oils it is said that they help to alter a person’s mood, health, mind, and cognitive function. It is also said that aromatherapy could substitute as treatment or prevention for certain diseases. There are many different types of oils used for aromatherapy in different ways for different outcomes. Such methods include the topical application, aerial diffusion, and direct inhalation. Topical application is any direct contact with the oil, used such as placing the oil in a bath or directly on to the skin. Aerial diffusion is where the oil is placed on the carpet around you or even on to a pillow or bed. Direct inhalation is a method where the oil is placed on the hands and rubbed together then while cupping your hands under your face to inhale the oils, this has a very powerful effect when used. Some uses of aromatherapy are for used as anti-depressants, relive stress, help with relaxation, insomnia, acne, itching and many more. To cure anxiety lavender, chamomile, rose, vanilla, and cardamom oils are all used for this. Lemon, jasmine, rosemary, sandalwood, and peppermint oils are all used to help with depression. When dealing with fatigue it is said that basil, cedarwood, clove, and eucalyptus all help. Headaches can be cured with lemon grass, thyme, ginger, and cinnamon oils. Caraway, chamomile, lavender, and rosemary oils are all used to help with menstrual cramps. The...

Coconut oil can be used for a wide variety of health, wellness and beauty issues. However, there seems to be a lot of confusion about the different types of coconut oil on the market. What's good and what's not so good, etc. Before you can make an intelligent decision about which coconut oil is right for you and your situation, you need to know a few of the basics about coconut oil before you begin your search.
The first group of chemical compounds to be discussed are terpenes. Terpenes are a very comprehensive group of metabolites which are known to contain essential oils that produces well-known scents in herbs belonging to the Lamiaceae plant family (Scott 2008). These scented compounds are usually found in the trichomes of basil, rosemary, lavender, etc. (Scott 2008). Electron micrograph images of these trichomes can be seen below. According to Keeling & Boltmann (2006), there are about 30 000 known types of terpenes which originated from structures created from terpene synthases. These terpene synthases can be broken up into three groups, monoterpene synthases, sesquiterpene synthases, and diterpene synthases (Keeling &...
In order to identify the uncertainties in Shell’s far environment I decided to use a PESTLE analysis approach to the oil and gas industry.
Performing this experiment, we used the technique called Acid-Base extraction to isolate Eugenol, which is one of the main ingredients of clove oil. Acid-Base extraction is the most efficient method for isolating organic component; it is efficient because it purifies the acid and base mixture based on their chemical identities. We have seen throughout this experiment that acid and base play an important role, when it comes to solubility in water. Our basic knowledge of acid and base is acid is a proton donor and base is a proton acceptor. This ideology helps us to understand why organic compounds are not soluble in water. When compounds tend to be insoluble, we have to use acid and base reaction, to change its solubility. The changes that occurred
Piperine has been shown in studies to reduce the risk of cancer by neutralizing free radicals within the body as well as eliminate reactive oxygen species. Both free radicals and ROS can cause cellular oxidative stress and may lead to some cancers as well as early onset of aging, and certain genetic mutations. Piperine also has the ability to stimulate the pain-sensing nerves and this gives pepper its’ pungency. Piperine also aids in digestion by triggering pancreatic and gastro digestive enzymes that will chemically break down the food that we have consumed. Piperine is such an important part of the human diet (in the form of black pepper) and because it is a natural product, there are fewer side effects associated with piperine as a medicine. Natural products as medicine are so important because they allow pharmaceutical companies to research their effects without so many associated risks and can lead to the development of synthetic, modern pharmaceuticals based on the characterization of the natural products. The research of natural, medicinal products leads to many medical

The freshly squeezed citrus juices of Lemon,lime and orange were analysed through titration over the period of 2 weeks. Initially the lime juice was found to be slightly more acidic than the other juices followed by lemon juice and then orange juice since it is known that usually lime is more acidic than lemon and orange. It was hypothesised that the acidity of each juice will increase or decrease after the period of two weeks depending upon the sugar content of that citrus fruit that the juice is extracted from. The acidity of the juice with the highest sugar level will gradually increase over the period of time since sugar contribute to the the fermentation of the citrus juice to lactic acid. The hypothesis was shown to be correct;however
