Background: The use of nutritional supplementation of the brewer&#039;s wort can be an interesting option to increase cell viability and yeast fermentability. </P><P> Objective: This study aims to evaluate the effects of the variables wort concentration and nutritional supplementation with palm oil in the production of beer in high-density wort. </P><P> Methods: The process effects were evaluated through the central composite rotational design of type 22 associated with the Response Surface Methodology (RSM). The fermentations were carried out using the commercial Saccharomyces cerevisiae yeast, lager type, at 15&#176;C. </P><P> Results: The mathematical models and RSM obtained were an efficienct strategy to determine the optimum fermentation point for the ethanol volumetric productivity (wort concentration of 20.90 &#176;P and palm oil content of 0.19 % v/v) and for the apparent degree of fermentation (wort concentration of 16.90 &#176;P and palm oil content of 0.22% v/v). There was a good correlation between the experimental values observed and predicted by the model, indicating that the fit of the model was satisfactory and it can be inferred that the increase of the wort concentration and the nutritional supplementation with the palm oil reached an ethanol volumetric productivity of 0.55 g/L.h and an apparent degree of fermentation of 50.20 %. </P><P> Conclusion: Therefore, it can be concluded that our study demonstrates that nutritional supplementation with palm oil is an alternative and promising option for the breweries to increase productivity. There are recent patents also suggesting the advantages of using alternative nutritional supplements in beverage production.

This research was conducted for evaluation of contamination of pig fat on vegetable cooking oil using transmission polarization method. The sample used is palm oil that has been contaminated with chicken oil and pork oil, with variations of chicken oil and pork oil content. The light source used is a green laser with a wavelength of 532 ± 10 nm. Measurements are made by observing the change in the transmission polarization angle that occurs when no external electric field is provided and by external electric field generated from two copper plates given a voltage of 0-6 kV. Test results show that palm oil contaminated with pig oil has the greatest change in polarization angle compared to pure palm oil and palm oil that has been contaminated with chicken oil. This is because the content of saturated fatty acids in pig oil is greater than pure palm oil and chicken oil. With these results, the transmission polarization method is expected to become a method for the evaluation of halal of cooking oil.Keywords: Transmission Polarization, Electrooptics, Cooking Oil, Impurities of Lard, Halal

Nutritional supplements such as L-carnitine and taurine have been found to be beneficial in dogs and cats with certain cardiac diseases. However, not all animals with cardiac disease respond to nutritional supplementation, which means that further work must be done to identify causes of cardiac disease. Herbal therapies have been used in dogs and cats based on information available from their use in humans. This paper reviews the possible benefits and side effects of L-carnitine, taurine, and herbal supplements.

SYNOPSIS Response surface methodology (RSM), central composite design (CCD), and desirability functions were used for modelling and optimization of the operating factors in chlorite and talc (collectively termed 'mica') flotation. The influence of pulp pH, cyanide (NaCN) consumption, and particle size was studied with the aim of optimizing ssilicate flotation while minimizing recoveries of galena, chalcopyrite, and sphalerite. Flotation tests were carried out on a representative sample of a complex sulphide ore from Draa Sfar mine (Morocco). The model predictions for the flotation of each of the minerals concerned were found to be in good agreement with experimental values, with R2 values of 0.91, 0.98, 0.99, and 0.90 for mica, galena, chalcopyrite, and sphalerite recoveries, respectively. RSM combined with desirability functions and CCD was successfully applied for the modelling of mica flotation, considering simultaneously the four flotation responses to achieve the maximum recovery of mica and minimal loss of Pb, Cu, and Zn to the flotation concentrate. Keywords: chlorite, talc, flotation, response surface methodology, central composite design, optimization.

In bodybuilding, the physical training takes different aspects, in particular the relationship with a specific diet and a substantial contribution of nutritional supplements. The diet for amateur bodybuilders is usually poor, having a negative impact in achieving sportive performance, because the muscle strengthening is closely bounded to vitamins, proteins, carbs, minerals, etc. In this study we have tested the hypothesis according to which in bodybuilding, achieving a good physique and sportive performance is not possible without nutritional supplementation. The study revealed that the athletes manifest a great interest into diet, corroborated with a protein supplementation in different concentrations.

Abstract In the present study, fenugreek and aloe vera were investigated for the removal of turbidity (TUR), total suspended solids (TSS) and chemical oxygen demand (COD) from POME by using a central composite design (CCD) in the Design Expert software. The effects of three factors such as pH, coagulant dosage and flocculant dosage were analysed using jar test experiment and optimised using response surface methodology (RSM). The optimum results obtained from process optimisation analysis were pH 4, 24.13 g of coagulant dosage and 20 ml of flocculant dosage that are sufficient to remove 82.78 % of TUR, 83.40 % of TSS and 32.95 % of COD. The maximum error between the optimised values and the experimental values (82.78 % for TUR, 83.08 % for TSS and 33.76 % for COD) were below 4 %, indicating that satisfactory agreement was achieved. This showed that modelling and optimisation of the coagulation-flocculation process can be achieved by RSM approach. From analytical studies, it was found that the interactions between coagulant-flocculant and colloidal particles involve the mechanisms of charge neutralisation, adsorption and bridging, due to the active components such as amine (N-H) and hydroxyl (O-H) groups contained in the fenugreek and aloe vera.

Mesocarp fiber palm oil industrial waste can be processed into pulp, but this fiber still contains oil with varying levels. The difference oil content in fiber affects the amount of cooking solution required to make mesocarp waste into pulp. This study consists of two stages, namely the pretreatment stage of oil extraction to obtain variations in oil content in the mesocarp fiber waste and the delignification stage using the NaOH-ethanol solution with the ratio of solids:solvent is varied to 1: 8, 1:10 and 1:12. Oil content of the fiber was analyzed, it is consist of 9,5% oil. To vary the oil content, the fibers are soaked in ethanol at room temperature and the levels drop to 7%. And soaking at 40°C can lower the oil content drop to 2%. The obtained pulp had the largest cellulose content 50.77% from delignified product from fiber with 7.6% oil content and solids:solvent ratio: 1:10. While the lowest lignin that was 7.39% obtained at 2.5% oil content. In the delignification process with ratio 1:12, pulp produced is decreased in cellulose content and from FTIR results it is known that it occurs because of the degraded cellulose during the delignification process.

Three treatment parameters of supercritical CO2 have been optimized by a response surface method using central composite design to obtain isolate yield of flax rove. Influence of operating parameters including dosage of cellulase, temperature, and pressure on final response is evaluated. The results show that the experimental values are adequately fitted to a quadratic polynomial equation. The optimal isolate yield is obtained with 2% cellulase dosage under temperature of 50?C and pressure of 20 MPa. Mathematical model is also applied to describe the kinetic behavior of the treatment process, revealing that supercritical CO2 is a promising green solvent for the scouring and bleaching of flax rove.

Abstract Palm oil is the planet’s most exploited vegetable oil. However, its extensive commercialization has resulted in massive waste, particularly palm oil mill effluent (POME), contributing to severe environmental pollution. POME has a high concentration of oil and grease (O&G) with the mean value of 4,340 mg/L, exceeding the standard discharge limit of 50 mg/L. Hence, the recovery of oil content in POME is crucial as it could be a key material in biodiesel production. The oil droplets in POME exist in two phases: floating in the supernatant and suspended in the solids. During the solvent extraction process, the oil adsorbed by the solid particles is not entirely recovered. Thus, ultrasonication-based process intensification is introduced. Ultrasonication can break apart the solid particles and release the oil content using the principle of sound waves, thereby it will eventually increase the yield of oil recovery from POME. Although some studies were done on oil extraction from POME, the use of ultrasonication technique to enhance the extraction of oil from POME has never been done. The current research work is to investigate the feasibility of using ultrasonication technique to enhance the oil recovery from POME and compare it to a non-ultrasonicated POME. Overall, this research discovered that using ultrasonication as a pre-treatment would improve oil recovery yield from POME by 39.17% as compared to non-ultrasonicated sample under the optimum ultrasonication conditions of 30% amplitude and 30 seconds duration.
