Gum arabic, also known as acacia gum, is a natural gum consisting of the hardened sap of various species of the acacia tree. Originally, gum arabic was collected from Acacia nilotica which was called the “gum arabic tree”, in the present day, gum arabic is predominantly collected from two related species, namely Acacia senegal and Vachellia (Acacia) seyal. Producers harvest the gum commercially from wild trees, mostly in Sudan (80%) and throughout the Sahel, from Senegal to Somalia—though it is historically cultivated in Arabia and West Asia. The tree does well in northern part of Nigeria and can be commercially farmed there.
Gum arabic is a complex mixture of glycoproteins and polysaccharides. It is the original source of the sugars arabinose and ribose, both of which were first discovered and isolated from it, and are named after it.Gum arabic is used primarily in the food industry as a stabilizer. It is edible and has E number E414. Gum arabic is a key ingredient in traditional lithography and is used in printing, paint production, glue, cosmetics and various industrial applications, including viscosity control in inks and in textile industries, though less expensive materials compete with it for many of these roles.
While gum arabic is now produced throughout the African Sahel, it is still harvested and used in the Middle East. For example, Arab populations use the natural gum to make a chilled, sweetened, and flavored gelato-like dessert.
Gum arabic’s mixture of polysaccharides and glycoproteins gives it the properties of a glue and binder that is edible to humans. Other substances have replaced it where toxicity is not an issue, and as the proportions of the various chemicals in gum arabic vary widely and make it unpredictable. Still, it remains an important ingredient in soft drink syrup and “hard” gummy candies such as gumdrops, marshmallows, and M&M’s chocolate candies. For artists, it is the traditional binder in watercolor paint, in photography for gum printing, and it is used as a binder in pyrotechnic compositions. Pharmaceutical drugs and cosmetics also use the gum as a binder, emulsifying agent, and a suspending or viscosity increasing agent.[4] Wine makers have used gum arabic as a wine fining agent.
It is an important ingredient in shoe polish, and can be used in making homemade incense cones. It is also used as a lickable adhesive, for example on postage stamps, envelopes, and cigarette papers. Lithographic printers employ it to keep the non-image areas of the plate receptive to water. This treatment also helps to stop oxidation of aluminium printing plates in the interval between processing of the plate and its use on a printing press.
APILICATION
Food
Also called acacia after the original source, gum arabic is used as an emulsifier and a thickening agent in icing, fillings, soft candy, chewing gum and other confectionery. Its most important use in the food industry is in soft drinks, where it binds the sweeteners and flavorings into the beverage. [8]
Painting and art
Gum arabic is used as a binder for watercolor painting because it dissolves easily in water. Pigment of any color is suspended within the acacia gum in varying amounts, resulting in watercolor paint. Water acts as a vehicle or a diluent to thin the watercolor paint and helps to transfer the paint to a surface such as paper. When all moisture evaporates, the acacia gum typically does not bind the pigment to the papersurface, but is totally absorbed by deeper layers.[9]
If little water is used, after evaporation the acacia gum functions as a true binder in a paint film, increasing luminosity and helping prevent the colors from lightening. Gum arabic allows more subtle control over washes, because it facilitates the dispersion of the pigment particles. In addition, acacia gum slows evaporation of water, giving slightly longer working time.
The addition of a little gum arabic to watercolor pigment and water allows for easier lifting of pigment from paper and thus can be a useful tool when lifting out color when painting in watercolor.
Ceramics
Gum arabic has a long history as additives to ceramic glazes. It acts as a binder, helping the glaze adhere to the clay before it is fired, thereby minimising damage by handling during the manufacture of the piece. As a secondary effect, it also acts as a deflocculant, increasing the fluidity of the glaze mixture but also making it more likely to sediment out into a hard cake if not used for a while.
The gum is normally made up into a solution in hot water (typically 10–25 g/litre), and then added to the glaze solution after any ball milling in concentrations from 0.02% to 3% of gum arabic to the dry weight of the glaze.[10] On firing, the gum burns out at a low temperature, leaving no residues in the glaze. More recently, particularly in commercial manufacturing, gum arabic is often replaced by more refined and consistent alternatives, such as carboxymethyl cellulose (CMC).
Photography
The historical photography process of gum bichromate photography uses gum arabic mixed with ammonium or potassium dichromate and pigment to create a coloured photographic emulsion that becomes relatively insoluble in water upon exposure to ultraviolet light. In the final print, the acacia gum permanently binds the pigments onto the paper.
Printmaking
Gum arabic is also used to protect and etch an image in lithographic processes, both from traditional stones and aluminum plates. In lithography, gum by itself may be used to etch very light tones, such as those made with a number five crayon. Phosphoric, nitric or tannic acid is added in varying concentrations to the acacia gum to etch the darker tones up to dark blacks. The etching process creates a gum adsorb layer within the matrix that attracts water, ensuring that the oil based ink does not stick to those areas. Gum is also essential to what is sometimes called paper lithography, printing from an image created by a laser printer or photocopier.
Pyrotechnics
Gum arabic is also used as a water-soluble binder in fireworks composition.
PRODUCTION
While gum arabic has been harvested in Arabia, Sudan, and West Asia since antiquity, sub-Saharan acacia gum has a long history as a prized export. The gum exported came from the band of acacia trees that once covered much of the Sahel region: the southern littoral of the Sahara Desert that runs from the Atlantic to the Red Sea. Today, the main populations of gum-producing Acacia species are harvested in Mauritania, Senegal, Mali, Burkina Faso, Niger, Nigeria, Chad, Cameroon, Sudan, Eritrea, Somalia, Ethiopia, Kenya and Tanzania. Acacia senegal is tapped for gum by cutting holes in the bark, from which a product called kordofan or Senegal gum is exuded. Traditionally harvested by seminomadic desert pastoralists in the course of their transhumance cycle, acacia gum remains a main export of several African nations, including Mauritania, Niger, Chad, Nigeria and Sudan. The hardened exudations are collected in the middle of the rainy season (harvesting usually begins in July), and exported at the start of the dry season (November). Total world gum arabic exports are today (2008) estimated at 60,000 tonnes, having recovered from 1987–1989 and 2003–2005 crises caused by the destruction of trees by the desert locust. Sudan, Chad, and Nigeria, which in 2007 together produced 95% of world exports, have been in discussions to create a producers’ cartel.
The major inputs for commercial GUM ARABIC farming are; LAND, IMPROVED CULTIVERS, TRAINING, FERTILISER, DISEASE AND PEST CONTROL, FINANCE and MARKET.
LAND
Procuring Land for such commercial farming has to be done by professionals who have the eagle eye to decode the soil texture without much examination. It is also easier to source for land for agriculture through professionals because they have extensive network and can arrange Land for you in short notice and in a cost effective manner. There is little need to purchase land for farming in large scale from the beginning as this will tie down available capital, thus it is advisable to lease and subsequently pay for the land from the proceed of the farm. BUSINESS ADVISORY NETWORK is a guru in this regard and will help you arrange choice farm land at the best rate, all you have to do is to talk to us.
TRAINING
We will guide you on best planting season, spacing, fertilizer type, how to source fertilizer, fertilizer application. Weed control, Crops you may intercrop with AVOCADO, the effects of intercropping on AVOCADO yield, Storage and processing.
FINANCE
The central bank of Nigeria has a lot of incentives/ credits for commercial farmers at a reduced interest rate of 9% per annum. Most of these are organized by the central bank of Nigeria although accessed through the commercial bank. BAN will guide you on how to source credit under any of these credits listed below;
Agricultural Credit Guarantee Scheme Fund (ACGSF) The Fund guarantees credit facilities extended to farmers by banks up to 75% of the amount in default net of any security realized. The Fund is managed by the Central Bank of Nigeria, through this guarantee it is easy For commercial banks to loan to farmers not fearing
Agricultural Credit Support Scheme (ACSS) ACSS funds are disbursed to farmers and agro-allied entrepreneurs at a single-digit interest rate of 8.0 percent. At the commencement of the project support, banks will grant loans to qualified applicants at 14.0 per cent interest rate. Applicants who pay back their facilities on schedule are to enjoy a rebate of 6.0 per cent, thus reducing the effective rate of interest to be paid by farmers to 8.0 per cent.
Commercial Agriculture Credit Scheme (CACS) This credit scheme is specifically targeted to finance the country’s agricultural value chain (production, processing, storage and marketing). The maximum interest rate to the borrower under the scheme shall not exceed 9 per cent, inclusive of all charges.
Nigeria Incentive Based Risk Sharing System for Agricultural Lending ( NIRSAL) Risk is the single-most important factor that prevents banks from lending to agriculture. To change banks’ perception that agriculture is a high-risk sector, NIRSAL has a USD300 Million Risk-Sharing Facility that it uses to share their losses on agricultural loans through Credit Risk Guarantees. NIRSAL shares risk with banks ranging from 30% to 75% of face value depending on segment.
This also includes a guarantee fee of 1% per annum on outstanding protected principal and interest. Up to 40% of interest cost rebated to select value chain participants every 90 days if loan remains in good standing (no partial or full default). All crops, livestock and related supportive economic activity across the value chain are supported by this facility.
The news is that government is willing and doing everything to encourage farming in Nigeria because that’s where the country straight lies. Nigeria is endowed with arable land and fresh water resources when viewed as a whole with approximately 61 million hectares of the land cultivable while the total renewable water resources is about 280 km3/year; which include river Niger, river Benue, lake Chad, Osun river, Hadejia River, Bonny river and a host of others. The major soil types in Nigeria, according to FAO soil taxonomist are fluvisols, regosols, gleysols, acrisols, ferrasols, alisols, lixisols, cambisols, luvisols, nitosols, arenosols and vertisols. These soil types vary in their potential for agricultural use according to FAO.
Nigerian soils can be classified into groups made up of four (climatic) zones that are soil associations. The groups are:
- Northern zone of sandy soils
- Interior zone of laterite soils
- Southern belt of forest soils
- Alluvial soils Zones
Northern zone of sandy soils: This area lies in the very northern parts of the country. This area lies in the extreme north with proximity to the fringes of the fast- encroaching Sahara desert. It is characterized by soils formed by deposition of sand by the wind. These soils might have been formed from wind-sorted desert sands that accumulated over long periods of time when the Sahara desert encroached several kilometers south of its present limits. The soils of this zone are very good in the production of groundnut, sorghum, cowpea, and millet.
Interior zone of laterite soils: This zone is made up of a mixture of sand and clay. They are grey to black clay, poorly drained and seasonally flooded forming the “fadama”. The Biu Plateau has rich soil that is productive and offers prospects for the expansion of the areas of cotton production, soybeans, yam and other legumes.
Southern belt of forest soils: Soils in this zone broadly represent those of the humid, tropical forest climate zones of the south where the wet season is long, the harmattan season short and forest cover is dense. Local soil types depend largely on parent rock; where the underlying rocks are granite or clay, the soils is a rich clayey loam. These soils are very good in growing crops like cocoa, oil palm, rubber, Cassava.
Zone of alluvial soils: These soils are found along the flooded plains of rivers, deltas, along the coastal flats. This zone extends from the coastal inland and runs along the valleys of the Niger and the Benue rivers, thus cutting across the vegetational zones. Soils in this zone are characteristic of fresh-water soil of grey to white sand, grey clay and sandy clay with humid topsoil. Another group consists of brownish to black saline mangrove soils, with a mat of rootlets. This soil type is very good for rice etc.
FARM EQUIPMENT
BAN will also help in securing farming equipment. This may be achieved through the federal and state government partnership with the support of any of the credit schemes. Through this farm equipment can be acquired or leased.
MARKET
Demand for GUM ARABIC is high both locally and internationally.
SECURITY
Security of the farm is of utmost importance, thus adequate security must be put in place to eliminate/ reduce pilferage in the farm.
