Submit Manuscript | http://medcraveonline.com IntroductionBiscuit is a popular bakery product worldwide. Biscuit is widely accepted by all age group due to its longer shelf life, better taste and its position as snacks; it is also considered as a good product for protein fortification and other nutritional improvement [1]. Due to competition in the market and increase demand for healthy, natural, and functional products, attempt are been made to improve the nutritive value of cookies and functionality by modifying their nutritive [2]. Composite flour are being developed consisting as a substitute to primarily wheat flour in the production of baked products [3,4]. Composite flours consisting cereals with legumes, fibre sources and hydrocolloids which can serve as viable alternatives to wheat flour have been researched into. [5][6][7][8][9]. Major advantages of these composite flours are their enhanced nutritional (protein, antioxidants, fibre, minerals) in addition to being gluten-free [6,7]. In addition, composite flours enhance the utilization of local and underutilized local and inexpensive food raw materials in the production of bakery products. Millets (Penisetum glaucum) are groups of small seeded species of cereal crops or grains, widely grown around the world for food and staples [10]. Millet could also be malted and milled into flour or brewed into various drinks and can be as well dehulled and milled into flour. Millet is predominantly starchy and the bran layer of millet is good sources of b-complex vitamins [11]. It also serves as a source of antioxidant in our diets [11].Rice (Oritza sativa) is a principal leading food crop of the world and a staple food of over approximately half of the world's population. Rice flour is considerably lower in protein content compared with wheat flour and does not contain gluten, hence, it is good source of flour for people who are gluten intolerant [12]. Extruded snack with high nutritional and antioxidant properties have been developed from rice-based composite flour [3].Soybean (Glycine max) is a remarkable source of protein for both animals and human consumption and is also a leading source of edible oils and fats [13]. Soybean is the only source that contains all the amino acids, it is used in the production of bread, cookies and other composite flour has been reported [14][15][16]. Soybean is cheap and this with its advantage of high nutrient makes it widely accepted and used for various forms of meals and snacks.Tiger nut (Cyperusesculentus) is an underutilized crop reported to be high in dietary fibre content which could be effective in the treatment and prevention of many disease including colon cancer, coronary heart diseases, heart diseases, obesity and gastro intestinal disorder [17]. Tiger nut flour has been demonstrated to be a rich source of quality oil, vitamin E and contains some useful minerals such as iron and calcium which are essential for body growth and development [18]. Due to its high amino acids contents, tiger nut has inherent nutritional an...

“…It is known that phenolic compounds, in general, are capable of ionic dissociation (Mueller, 2001;Randhir et al, 2004), which makes possible to justify the antimicrobial activity of purified barbatic acid. The process of H + dissociation can lead to an acidification of plasmatic membrane surface of microorganism, resulting in H + -ATPase rupture that is required for ATP synthesis (Vattem et al, 2004;Maeda et al, 1999). Besides, it causes intracellular coagulation of cytoplasm constituents, leading the cell to death, or inhibiting its growth (Adham et al, 1998).…”

“…Besides, it causes intracellular coagulation of cytoplasm constituents, leading the cell to death, or inhibiting its growth (Adham et al, 1998). The Gram positive bacteria are more sensible to these compounds by presenting a simple membrane (Vattem et al, 2004). Despite the necessity for more detailed studies about the action mechanism of lichen substance against microorganisms, the in vitro effect of barbatic acid against S. aureus strains was evident.…”

“…The presence of phenolic derivatives in lichen is determinant for its antimicrobial activity. These substances generally acidify the bacterial cell and, consequently, cause cytoplasm membrane rupture, inactivate the enzymes, and interfere on the electrons transport process and in the oxidative phosphorilation (Mueller, 2001;Randhir et al, 2004;Vattem et al, 2004).…”

“…Another antibacterial mechanism of Qi 4 against the organism may be due to its ability to weaken the cell membrane by high tannic and gallic acid concentration. Anti-meticillin-resistant activity of Q. infectoria (Chusri & Voravuthikunchai, 2009) and anti-STEC O157 : H7 of cranberry pomace (Vattem et al, 2004) were correlated with the high ellagic acid concentration present. Structural elucidation indicated ellagitannin (C 34 H 28 O 22 , molecular mass 788.57 Da) as the major component in Qi 4 (result not shown).…”

The use of antimicrobial agents in the management of patients infected with Shiga toxinproducing Escherichia coli (STEC) O157 : H7 remains controversial. Here, we examined the antibacterial efficacy of a natural product, ellagitannin from Quercus infectoria (Qi 4), against the organism in a murine model. Streptomycin-pretreated mice were orogastrically inoculated with 2¾10 9 c.f.u. streptomycin-resistant E. coli O157 : H7. The results demonstrated a stable high level of STEC present in the faeces of the infected animals. The bacterial levels in infected mice receiving Qi 4 at MIC and 2¾MIC were not significantly different from those of the untreated group (t-test; P.0.05). In contrast, Qi 4 at 4¾MIC significantly reduced the numbers of STEC within 2 days (t-test; 0.05.P.0.01). No viable bacteria were detected between day 5 and day 10. Similarly, at day 10, no organisms were detected from the intestines of the Qi 4-treated group, while they were recovered at levels of 10 8-11 and 10 5-10 c.f.u. g "1 in the colons and caeca of the infected mice, respectively. Histopathological findings from the infected kidneys revealed a marked increase in the number of mesangial cells and mesangial matrix. Ultrastructural examination of the kidneys from the infected mice also demonstrated proliferation of mesangial cells and an increase in the mesangial matrix. Cellular injury of endothelial cells with irregular borders and cytoplasmic bleb formation were noted. In contrast, the effects were not observed in the animals treated with Qi 4. The results clearly indicated that administration of Qi 4 could effectively eradicate the colonization of STEC O157 : H7 in the intestinal tract of mice and prevent renal injury. This compound may be an alternative candidate for a therapeutic agent against infections caused by this dangerous organism.
