“…The moisture content facilitates the solubility of GA carbohydrate hydrophilic and hydrophobic proteins. The total ash content is used to determine the critical levels of foreign matter, insoluble matter in acid, calcium, potassium and magnesium (Mocak et al, 1998). The compositions of cations in the ash residue are used to determine the specific levels of heavy metals in the gum arabic quality (FAO, 1990(FAO, , 1996.…”

“…Most of the acacia gum (90 %) obtained for commercial use comes from Sudan, Africa (Joseleau and Ullmann 1990). The exudate is a hydrocolloid composed of various molecular components of D-galactose (~40 %), L-arabinose (~24 %), L-rhamnose (~13 %), D-glucuronic acid (~21 %), 4-O-methyl-D-glucuronic acid (~2 %), and polypeptide (~2 %) (Michel et al 1998;Mocak et al 1998). …”

One of the principal challenges in the collection of biological samples from air, water, and soil matrices is that the target agents are not stable enough to be transferred from the collection point to the laboratory of choice without experiencing significant degradation and loss of viability. At present, there is no method to transport biological samples over considerable distances safely, efficiently, and cost-effectively without the use of ice or refrigeration. Current techniques of protection and preservation of biological materials have serious drawbacks. Many known techniques of preservation cause structural damages, so that biological materials lose their structural integrity and viability. We review applications of a novel bacterial preservation process, which is nontoxic and water soluble and allows for the storage of samples without refrigeration. The method is capable of protecting the biological sample from the effects of environment for extended periods of time and then allows for the easy release of these collected biological materials from the protective medium without structural or DNA damage. Strategies for sample collection, preservation, and shipment of bacterial, viral samples are described. The water-soluble polymer is used to immobilize the biological material by replacing the water molecules within the sample with molecules of the biopolymer. The cured polymer results in a solid protective film that is stable to many organic solvents, but quickly removed by the application of the water-based solution. The process of immobilization does not require the use of any additives, accelerators, or plastifiers and does not involve high temperature or radiation to promote polymerization.

“…Chemical and physical techniques that have been adopted include infra-red spectroscopy, mass spectroscopy, NMR and HPLC (Dennis, 1998;Pickles et al, 2004). Where species specificity has not been absolute a multivariate analytical, or chemometric, approach has potential (Mocak et al, 1998). However, these techniques are not suitable for routine use as they either lack absolute specificity, and/or are expensive and require time and training (Dennis, 1998;Pickles et al, 2004;Woolfe & Primrose, 2004).…”

A number of enzyme-linked immunosorbent assays (ELISAs) have been developed for the detection of milk adulteration in dairy products. Target antigens have been caseins, lactoglobulins, immunoglobulins and other whey proteins. Polyclonal and monoclonal antibodies have been used in a variety of formats including direct, indirect, competitive and sandwich ELISAs. ELISAs have been successfully applied to the detection of cows' milk adulteration of sheep, goat and buffalo milk. Goat milk adulteration of sheep milk has also been detected. A number of ELISAs have also been applied to cheese. It is recommended that ELISA should be used in combination with PCR to ensure compliance with current legislation.
