Determination of nickel in alcoholic beverages by FAAS after online preconcentration using mandarin peel (Citrus reticulata) as biosorbent
A solid phase extraction method was developed for the direct determination of nickel in alcoholic beverages. This method is based on the adsorption of nickel onto the peel of Citrus reticulata (mandarin orange). The solution pH, amount of adsorbent, sample and eluent flow rates, eluent concentration and matrix effects were investigated using multivariate optimization strategies. Desorption studies were carried out with 1 mol L-1 HCl. The optimum extraction conditions were obtained using a sample pH of 6.0, sample flow rate of 4.3 mL min-1, 50 mg of sorbent mass and 1.0 mol L-1 HCl at a flow rate of 2.0 mL min-1 used as elu...

Enzymatic hydrolysis optimization of sweet potato (Ipomoea batatas) peel using a statistical approach
In this work, two-step enzymatic hydrolysis of sweet potato peel was optimized. The effects of time, enzyme dose and temperature on glucose concentration were investigated. The Box-Behnken design was applied and a total of 17 experimental runs were generated for each step. For the liquefaction step, an ANOVA test showed the quadratic model obtained to be significant (p

MONITORING OF BIOSURFACTANT PRODUCTION BY Bacillus subtilis USING BEET PEEL AS CULTURE MEDIUM VIA THE DEVELOPMENT OF A NEURAL SOFT-SENSOR IN AN ELECTRONIC SPREADSHEET
ABSTRACT This work investigated the combination of agitation and aeration conditions in a bench-bioreactor to identify the optimal biosurfactant production from substrate based on beet peel and glycerol from a biodiesel process. Thus, a central composite rotatable design (CCRD) and responses were evaluated by response surface methodology (RSM) modeling. The optimal operation values determined were 200 rpm (agitation) and 0.5 vvm (aeration), reaching values of 1931.2 mg/L of crude biosurfactant concentration and 28.37 mN/m of surface tension. For the development of a mathematical model based on an artificial neural network ...

Synergistic effects of low-/medium-vacuum carbonization on physico-chemical properties and stability characteristics of biochars
In this study, thermochemical conversion of orange peel to biochar under low- and medium-vacuum pyrolysis conditions were investigated for product distribution and stability characteristics of biochar. The pyrolysis experiments were executed under three different conditions i.e., N2 atmosphere (without vacuum), low-vacuum (1013.2 Pa) and medium-vacuum (101.3 Pa) in the temperature range of 300–700 °C. The derived biochars were characterized for its aromaticity, polarity, elemental composition, pH, electrical conductivity, surface area, thermal decomposition, FTIR spectroscopy and chemical oxidation properties. Res...

Banana peel ameliorated hepato-renal damage and exerted anti-inflammatory and anti-apoptotic effects in metal mixture mediated hepatic nephropathy by activation of Nrf2/ Hmox-1 and inhibition of Nfkb pathway
This study evaluated the protective role of banana peel extract (BP) on heavy metal mixture (HMM) mediated hepatorenal toxicity using a rat model. Twenty-five female Wistar albino rats were weight-matched and divided into five groups of five female rats each. Group 1(control) received deionized water only. Group 2 received HMM only (20 mg·kg-1 of Pb, 0.40 mg·kg-1 of Hg, 0.56 mg·kg-1 of Mn and 35 mg·kg-1 of Al). Groups 3, 4 and 5 were co-administered with the same metal mixture with BP at 200, 400 and 800 mg·kg-1, respectively. Treatments were through oral gavage for 60 days; animals were sacrificed pentobarbital anest...

Cleopatra and Sour Milk —The Ancient Practice of Chemical Peeling
Chemical peels are one of the most commonly performed cosmetic procedures and have long been used for the treatment of disorders of pigmentation, acne, and fine rhytides. The procedure involves applying an exfoliating agent —such as an α-hydroxy acid (AHA)—to the skin to destroy the epidermis and/or dermis layer, which allows the skin to rejuvenate.
