Background: Avocado (Persea americana Mill), is a subtropical, evergreen fruit tree belonging to the family Lauraceae. Due unique climacteric nature of fruit, avocado starts ripening immediately after harvest and have poor post life. Since thermal processing has adverse effects on quality, challenging. Methods: slices were subjected quick freezing (-20oC within 30 minutes) pre-treatment with su...

In countries that are humid throughout the year, mold is a common problem that can occur even on a computer keyboard. Mold is smelly and may damage computer keyboards. It is caused by fungal spores in the air. It can also affect occupants’ health. This study aimed to evaluate the efficiency of potassium sorbate as a biocide to reduce the viability of indoor airborne fungus in a higher education...

Understanding how sorption depends on temperature a molecular basis has been made difficult by the coexistence of isotherm models, each assuming different mechanism and routine application planar, multilayer models (such as Brunauer–Emmett–Teller (BET) Guggenheim–Anderson–de Boer (GAB)) beyond their premises. Furthermore, common observation that adsorption isotherms measured at temperatures fal...

Ultrasound technique was used to produce native and acetylated cassava starch particles containing potassium sorbate (KS). In order obtain an active packaging, films with addition of KS (NKSPF) or added (AKSPF) were formulated. As control systems, without (CF) that not retained in (KSF), produced. The NKSPF AKSPF microstructure consistent composite materials. Tensile test revealed CF KSF ductil...

In the title salt, C(6)H(9)N(2) (+)·C(6)H(7)O(2) (-)·2H(2)O, the non-H atoms of the 2-amino-4-methyl-pyridinium cation are coplanar, with a maximum deviation of 0.010 (1) Å. In the crystal structure, the pyridinium N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The sor...

A direct comparison of quasielastic neutron scattering experimental measurements and molecular dynamics computer simulations is carried out for the first time for hydrogen and deuterium confined in the nanostructure of faujasite type zeolites at a temperature of 100 K, in order to investigate the dependence of sorption thermodynamics and sorbate dynamics on the sorbed phase concentration. The c...

Maximum capacities were determined for adsorption of six polycyclic aromatic hydrocarbons, seven polychlorinated biphenyls, and five chlorobenzenes in both the slowly desorbing domain and the very slowly desorbing domain of a sediment. For separate compound classes in the two desorption domains, log-transformed maximum adsorption capacities were linearly related to the relative magnitude of the...
