Glycerol: The main component of triglycerides

Glycerol is the main component of triglycerides, found in animal fat, vegetable oil, or crude oil. Glycerol is derived from soap or from biodiesel production. It occurs naturally in wines, beers, bread, and other fermentation products of grains and sugars.

Glycerol is the simplest of the alcohols and is known by propane-1,2,3-triol according to IUPAC. It is also commercially known as glycerin, 1,2,3-propanotriol, trihydroxypropane, glyceritol or glycidic alcohol.

Glycerol (propane-1,2,3-triol) is a multi-functional organic compound, showing hydrophilic and hydrophobic properties due to a stable chemical structure with three hydroxyl groups. Due to its thermal stability, a high energetic availability for bond breaking and formation of other compounds is required.

Physically, glycerol is a water-soluble, clear, almost colorless, odorless, viscous, has a syrupy-sweet taste, hygroscopic liquid with a high boiling point. Chemically, glycerol is a trihydric alcohol, capable of being reacted as an alcohol yet stable under most conditions.

Glycerol is a liquid containing three hydrophilic hydroxyl groups that are responsible for it being hygroscopic and its solubility in water.

Currently, glycerol is mainly used as an intermediate chemical for the production of a variety of products, such as cosmetics, food, pharmaceuticals, etc.

Glycerides are compounds formed by esterification of glycerol and one to three fatty acids. Glycerides can be found in oleaginous products, such as cooking oil, rapeseed oil, waste greases, pork lard, biomass from algae, i.e., in almost any vegetable oil or animal fat.

The uses of groundnut

Originally groundnuts were considered to be food for animals; then they were used as food for slaves. They have now become an important source of protein in many developing countries.

Groundnut is rich in protein, oil and some vitamins and minerals. They are used in various forms, which include groundnut oil, roasted, and salted groundnut, boiled or raw groundnut or as paste popularly known as groundnut (or peanut) butter.

When cooked and pureed, thick rich groundnut sauce is an important feature of daily cooking, especially in West Africa. The tender leaves are used in certain parts of West Africa as a vegetable in soups. Being a grain legume, peanut has an important nutritional value for human beings, and its nutritional value has been exploited for combating malnutrition in children.

Groundnut oil is the most important product of the crop, which is used for both domestic and industrial purposes. When cooked and pureed, thick rich groundnut sauce is an important feature of daily cooking, especially in West Africa.

About two thirds of the world production of groundnuts is utilized as an edible oil, making it one of the world’s leading oil seed crops. In most of the developing countries kernels are used for oil extraction, food and as an ingredient in confectionery products. Following extraction, the residual cake is processed largely for animal feed, but is also used for human consumption.

Groundnut oil is the cheapest and most extensively used vegetable oil in India. It is used mainly for cooking, for margarine and vegetable ghee, salads, for deep-frying, for shortening in pastries and bread, for pharmaceutical and cosmetic products, as a lubricant and emulsion for insecticides and as a fuel for diesel engines. The press cake containing 40-50% protein is used mainly as a high-protein livestock feed and as a fertilizer.

Peanut is also used for feed through the valorization of oil cakes that represent an interesting source of proteins for livestock. In most Sahelian countries, groundnut straw is also used as dried hay and represents a major source for cattle feed during the dry season.

Groundnuts are also consumed whole as snacks, and in confectioneries and peanut butter. In this form, they are usually roasted before use. This accentuates the flavor which contributes to consumer acceptance.

Crystallization in food

In terms of molecular structure, there are three forms of powders: crystalline, amorphous, and the mixture of the two. Solid foods can either be amorphous (such as hard candies or milk powders) or crystalline (such as chocolate or ice cream).

Low molecular weight carbohydrates, such as lactose, glucose, sucrose, and organic acids and polyols, can either be in crystalline or amorphous states, depending on the processing conditions and presence of other components in the system.

In many food products, the crystalline structure within is important to product quality, texture, and stability. Crystallization determine product appearance, mechanical properties during handling, mouthfeel during consumption, and shelf stability.

The formulation, processing conditions, transport and storage conditions govern the crystalline microstructure in foods and thus, the shelf stability of these food products.

Crystallization is also important during the processing of certain food components, as a purification or separation step.

Crystals may promote a certain texture, as in products such as frozen foods (ice cream), grained sugar confections and fat-based products (e.g. butter, margarine and chocolate). In confectionery products such as fondants and creams, controlled crystallization results in the formation of a large number of fine crystals that give the desired texture.

The principle of crystallization is based on the limited solubility of a compound in a solvent at a certain temperature, pressure, etc. Crystallization involves the following steps.
*First, the liquid must attain a level of supersaturation or supercooling. This is accomplished through cooling or evaporation.
*Once a critical supersaturation has been exceeded, nucleation occurs. Nucleation involves the formation of the crystalline phase from supersaturated solutions can occur by either a spontaneous or a forced nucleation mechanism.
*Once nuclei form, they grow into product-sized crystals through incorporation of additional molecules into the crystal lattice. Crystallization continues until equilibrium is achieved between the liquid and crystalline. The balance being determined by the solubility (concentration) and the temperature. The driving force making the crystals grow is the concentration excess (supersaturation) of the solution above the equilibrium (saturation) level.
