how to extract groundnut oil

Extraction Process

The first step is to get the materials, which are;
1. Groundnut seed
2. Mill
3. Source of heat (for pre-blanching).
STEP #1:
Having succeeded in getting the materials, you then proceed to clean the seed. Note that cleaning here does not mean washing the seed. Cleaning here is picking the extragenous materials (dirts) in the seeds. This is very important because ignoring this step will affect the taste and colour of the oil. Dirt here also refer to the spoilt seeds (rotten seeds) or seeds with fungi like mucor growing on them. You must do this in order to get a quality end product that will be nutritive in value.
STEP #2:
You then proceed by carrying out a process called pre-blanching. This is heating the seed in a low heat. Why

PEAR

What's New and Beneficial About Pears For nutritional reasons, we're often advised to consume the skins of fruits. However, it's less often that research provides strong evidence in support of this advice. Recent studies have shown that the skin of pears contains at least three to four times as many phenolic phytonutrients as the flesh. These phytonutrients include antioxidant, anti-inflammatory flavonoids, and potentially anti-cancer phytonutrients like cinnamic acids. The skin of the pear has also been show to contain about half of the pear's total dietary fiber. In recent studies measuring risk of type 2 diabetes in U.S. women, pears have earned very special recognition. Researchers now know that certain flavonoids in food can improve insulin sensitivity, and of special interest in this area have been three groups of flavonoids (flavonols, flavan-3-ols, and anthocyanins). All pears contain flavonoids falling within the first two groups, and red-skinned pe

Aubauf Method - Building Up

Atoms Are Built Up by Adding Electrons Although the nucleus of an atom is very dense, the electrons around it can take on a variety of positions which can be summarized as an electron configuration. An element's electron configuration can be represented using energy level diagrams, or Aufbau diagrams. The Aufbau principle (from the German Aufbau meaning "building up, construction") describes a model-building method in which an atom is "built up" by progressively adding electrons. As electrons are added, they assume the most stable shells with respect to the nucleus and the electrons already present. Filling in an Aufbau Diagram The order in which orbitals are filled is given by the Madelung rule. The rule is based on the total number of nodes in the atomic orbital, n + ℓ, which is related to the energy. In this context, n represents the principal quantum number and ℓ represents the azimuthal quantum number. The values ℓ = 0, 1, 2, 3 correspo

Building Self-Confidence Preparing Yourself for Success! Learn how to become more self-confident with James Manktelow and Amy Carlson. From the quietly confident doctor whose advice we rely on, to the charismatic confidence of an inspiring speaker, self-confident people have qualities that everyone admires. Self-confidence is extremely important in almost every aspect of our lives, yet so many people struggle to find it. Sadly, this can be a vicious circle: people who lack self-confidence can find it difficult to become successful. After all, most people are reluctant to back a project that's being pitched by someone who was nervous, fumbling, and overly apologetic. On the other hand, you might be persuaded by someone who speaks clearly, who holds his or her head high, who answers questions assuredly, and who readily admits when he or she does not know something. Confident people inspire confidence in others: their audience, their peers, their bosses, their customers, and
