	[Abstract] [PDF] Microplastics (MPs) are a contemporary societal concern that have been identified as a growing environmental hazard as a result of improper disposal. The goal of this research was to study the MPs found in Lanchester's freshwater prawn, Macrobrachium lanchesteri, in three different sites along the irrigation canal in central Thailand.In each site, twenty individuals (n = 20) of M. lanchester were examined for MP content. A total number of MPs in site 1 was 1093 items/20 ind. (range 35-80), with an average of 60.72 ? 10.54 items/individual. Site 2 was 1001 items/20 ind. (range 34-71), with an average of 50.05?8.71 items/individual, and site3 was 1039 items/20 ind. (range 33-71), with an average of 51.95?10.62 items/individual. Among the various shapes, types, and colors of MPs identified, fiber and fragment, as well as blue, were the most common. The prawn had the greatest MPssize range of 200?250 ?m in each point, followed by MPssize ranges of 250?500 ?m and <100 ?m. FT-IR data confirmed 1 particle of ethylene propylene rubber (EPR), 4 particles of polyethylene glycol (PEG), 1 particle of polyethylene terephthalate (PET), 1 particle of bis (2-ethylhexyl) phosphate, 1 particle of cellulose acetate, 2 particles of glyceryl polypropylene glycol ether, 1 particle of polyester (PE), and 1 particle of hydroxyethyl cellulose (HEC). The findings of this study provide detailed and useful information for a better understanding of MP contamination in the region, and M. lanchesteri is proposed as an appropriate species for monitoring MPs in freshwater ecosystems.

	[Abstract] [PDF] The aim of this study was to investigate the effectiveness of developing a roll-on deodorant that canreduce armpit microbiota bacteria to decrease armpit odor. The richest apocrine sweat glands in the armpit region secrete a variety of odor precursors that are transformed into volatile odoriferous substances by bacterial enzymes on the skin surface. The dominant armpits microbiota included four groups of bacteria such as Staphylococcus spp., Micrococcus spp., Corynebacteriumspp., and Propionibacteriumspp., and also fungi or yeasts. Two formulas of the roll-on deodorant products,RDEOF-1 and RDEOF-2 were developed. RDEOF-2 containedan ethanolic extract ofRhinacanthus nasutus (L.) Kurz leavesinhibitedseveral microorganisms, including Gram-positive and Gram-negative bacteria. Sixteen healthy volunteers showed satisfactory assessment forRDEOF-2 that was greater than RDEOF-1. Armpit bacteria were collected by swab method and armpit odor was evaluated by ASTM method. Resultsshoweddominant bacteria of two genera includingStaphylococcus spp. and Corynebacterium spp. in all swab samples that mainlycause armpit odor. Armpit bacterial numbers before using deodorants were high inthe range of 2x103 to 9x105 (CFU/mL). After applying RDEOF-1 and RDEOF-2,bacterial numbers decreased in the range of 1x103 to 8x105and 3x102 to 4x105(CFU/mL), respectively. Armpit bacteria were found in males more than in females. Deodorant products containing R. nasutusextract have been shown to reduce thebacteria that cause armpit odor. Therefore, the development of the deodorant product with natural plant extracts is warranted.

	[Abstract] [PDF] The objective of this research was to produce a biochar from bamboo handicraft waste via pyrolysis process using modified 200 L steel drum kiln. A temperature outside the kiln-produced biochar appeared around 500-600 oC closely related to those of slow pyrolysis. The physical and chemical properties of bamboo biochar (BB) were characterized by using proximate and ultimate analysis, Brunauer?Emmett?Teller surface area techniques, elemental analysis, scanning electron microscopy coupled with an energy dispersive spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray diffraction. It was found that 28.76 ? 2.22 % of BB yield with 77.07 ? 1.92?% fixed carbon. As the morphology properties, its surface area and total pore were 247.5 ? 7.1 m2.g-1 and 0.16 ? 0.02 cm3.g-1, respectively. Batch test for removal of natural organic matter (NOM) from real water, Nakhon-nayok River, by adsorbed on BB was studied. The results showed that the reducing percentages of dissolve organic matter (DOC) and absorbance at 254 nm wavelength (UV254) at equilibrium were 71.33 ? 1.46 and 76.51 ? 2.01, respectively, while the adsorption capacity was 4.75 mg.g-1 DOC. Pseudo-second order kinetic model was the best suited for describing the adsorption of DOC onto BB. This suggests that interaction of NOM on BB were explored in terms of multicomponent adsorption, which the heterogeneous distribution of the adsorptive sites at biochar surfaces. This biochar is thus suitable for the adsorption of NOM from surface water and as a low cost effective adsorbent in the treatment of wastewater. The biochar can be applied for a variety of purposes for example: as biofuels, adsorbents, and as soil amendments. In addition the biochar kiln is also small and easy to create, no smoke, inexpensive, easy to use, don?t spend a lot of time and eco-friendly processing.

	Low-fat, Plant-based Ice Creams Formulated with Rice Bran Oil and Rice Bran Oil Organogel

	Page: -
	[Abstract] [PDF] Low-fat, plant-based ice creams were novelty formulated by replacing milk with rice bran oil and rice bran oil organogel emulsion. The protein in milk was substituted by soy protein. The viscosity and emulsion stability of the plant-based ice cream mixtures were measured and compared with conventional milk ice cream. Frozen ice cream properties, including overrun, firmness, and melt down rate were investigated as well as nutritional and sensory properties. Result found that the viscosity of the plant-based ice creammix including organogel (398 mPa?s) and rice bran oil (363 mPa?s) exhibited higher value than those of conventional ice cream mix (289 mPa?s). The emulsion stability of milk, organogel and rice bran oil ice cream mixtures were 88.72 ? 0.80, 88.00 ? 0.10, and 80.12 ? 0.65, respectively. The overrun of organogel ice cream (38.31? 0.91) showed lower quality characteristics than the milk ice cream (39.40 ? 1.03)while rice bran oil ice cream had the lowest overrun (37.02? 0.01) (P<0.05). The reduction of overrun related with texture of ice cream. The firmness of rice bran oil ice cream (16.4? 0.91) showed lower quality characteristics than organogel ice cream (15.3? 0.87) followed by the milk ice cream (14.4? 0.91). The melt down rate of plant-based ice creams (organogel: 0.46? 1.75, rice bran oil: 0.45? 1.65) are improved when compared with the milk ice cream (0.67? 1.65) may be because of high viscous of ice cream mix and the properties of soy protein. The nutritional properties were improved for plant-based ice cream formulations. Especially, total fat content of organogel was lower than rice bran oil because of the lower fat of organogel. Scores of the taste and flavors was decreased as well as appearance and color characteristic.Texture and body of the organogel ice creams were not different when compared to the conventional milk ice cream. Although, firmness of organogel was higher than conventional ice cream but panelists cannot perceive the difference. Nevertheless, rice bran oil ice cream hadthe lowest score (P<0.05) in texture and body which may be due to the high firmness value. Therefore, low-fat, plant-based ice cream formulated with rice bran oil organogel is a successful approach in order to obtain lower fat without compromising their qualities except the taste and flavor because of soy protein flavor.

	[Abstract] [PDF] Leum Pua is native Thai glutinous rice that contains antioxidantshigher than other colored rice. The purposes of this study were to develop transethosomes (TEs) extracted from Leum Phua rice by hot method. The influence of rice extract and rice bran oil concentrations to investigate on physical properties of the TEs.The formulation of TEs was performed by selecting the optimal ratio obtained from a mixture of glutinous rice extract at the concentration 20, 30 and 40% (w/v) and rice bran oil 20, 25 and 30% (w/v). Characterization of the TEs was based on results from particle size, polydispersity index, zeta potential,entrapment efficiency and stability testing.Leum Pua glutinous rice was extracted by 95% ethanol. The extracts were to develop TEs using rice bran oil as phospholipid, lecithin as permeation enhancer, Span 80 and Tween20 as edge activator (surfactant) in their formula. Furthermore, the required size of ethosome vesicles wasprepared by using sonication. Results showed that the optimized TEs formulation with particle size below 300 nm could be achieved by using rice extract at the concentration 30 and 40% (w/v) and rice bran oil 20% (w/v). At a concentration of rice extract 40% (w/v) and rice bran oil 20% (w/v) showed the highest entrapment efficiency (68.94?2.9%). The good colloidal characteristics had a particle size (PZ) of 233.0?12.9 nm, polydispersity index (PDI) of 0.314?0.078 and zeta potential (ZP) of -51.4?0.24 mV. The TEsoptimized formulationwas stable at room temperature and also at elevated temperature conditions (45oC/75% RH) for 3 months. Therefore, based on the current study, the potential of employing the novel carrier transethosomal-loaded nanoparticles of Leum Phua rice extracts could serve as an effective dermal delivery. The development ofTEs for topical delivery can lead to value added of native Thai glutinous rice.
