The effect of replacing shortening and sugar on the physical and chemical properties of mangaba ice cream and its acceptability were evaluated. Ice cream formulations were tested with the following fat replacers: Selecta Light, Litesse, and Dairy Lo and the following sugar substitutes: Lactitol and Splenda. All formulations were subjected to physical, chemical, and microbiological analyses and evaluated by acceptability tests. In the sensory analysis, it was observed a larger acceptance of the formulations containing Selecta Light (SL) and the combination of Litesse, Lactiol, and Splenda (LLS). The largest reduction in total energetic value (50%) was observed in the formulation LLS. The use of fat and/or sugar substitutes caused a reduction in the air incorporation (overrun) and affected viscosity. The highest melting speed was observed in the formulation with Dairy-Lo, Lactitol, and Splenda. All formulations showed good levels of global acceptability and appearance. The substitution of shortening for fat replacers caused a reduction in air incorporation and changes in ice-cream viscosity. The low-fat mangaba ice-cream elaborated with Selecta Light was the best formulation in terms of viscosity and air incorporation when compared with the control. It also showed a good level of acceptability and low fat content.

This review article elaborates the pH and nutrients detection sensitive materials and methods along with their principle of operations, merits, demerits, and application area. The sensitive materials used in the sensors react with the analytes and shows variation in electrical, physical, chemical, biological and optical parameters. The glass probe method, optical light spectroscopy, ion-selective electrodes, ion-selective field effective transistors, electrochemical interdigitated conductimetric method and microcantilever methods are the predominant techniques to detect the pH and nutrients in various medium. Most of the researchers have discussed the fabrication of pH and nutrients sensors individually in various applications, but very few numbers of sensitive materials and techniques discussed to detect the pH and nutrients in the soil. There is a strong relationship between pH and nutrients in the soil based on a number of important physical and chemical properties of the soil. We are strongly recommending that soil pH and nutrients measuring sensors can develop through the combinational approach of pH and nutrients with the help of nanostructured materials, seems to be more effective for agriculture applications.

AbstractThe SuperMALT survey is observing 76 MALT90 clumps at different evolutionary stages (from pre-stellar or quiescent to HII) in high excitation molecular lines and key isotopomers using the Apex 12m telescope with an angular resolution of ∼20” and a velocity resolution of ∼0.1 km/s. The aim of this survey is to determine the physical, chemical, and kinematical properties of the gas within clumps as they evolve. Here we report some preliminary results based on observations of the J=3-2 & 4-3 lines of HNC, HCN, HCO+, N2H+ and of the J=3-2 line of the isotopologue H13CO+. We find that the morphologies and line profiles vary with the evolutionary stage of the clumps. The average line width increases from quiescent to HII clumps while line ratios show hint of chemical differences among the various evolutionary stages.

Nata de coco one of the beverage products produced from fermented coconut water using the help of starter Acetobacter xylinum. This product is very popular with people ranging from children to parents because the shape and texture resembles a gel.  This study aims to evaluate the physical, chemical and heavy metal content in nata de coco made using nitrogen sources from NPK. The experimental plan used by The Complete Randomized Plan (RAL) is a single factor, the factor is the concentration of NPK consisting of 5 levels of K1 = 0.25%, K2 = 0.5%, K3 = 1%, K4 = 1.5%, K5 = 2%.  Each treatment was repeated 5 times and the total sample observed a total of 25 pieces. The observed observation parameters of nata thickness, nata weight, total fiber content of nata and metal residue content in nata include Cu, Zn, Pb metals, all of which are observed at the end of fermentation (the 14th day of fermentation). The initial parameters of the formation of nata are observed from the beginning of fermentation until the nata sheet is first formed. The results showed that nata de coco made using nitrogen source from NPK concentration of 0.1% has the best physical and chemical properties namely thickness of nata: 1,438 cm, weight of nata: 309 grams, initial formation of nata 3.2 days and total fiber content of nata: 4.024%. The use of NPK produces residues in the form of heavy metals Cu and Zn while pb heavy metals are undetectable. The higher the concentration of NPK given as a source of nitrogen, the higher the residues of heavy metals Cu and Zn in the nata de coco.
