fruit leather is one of dried product with variable production, good marketing and popular consumption in many countries of the world. in this research, the effect of concentration temperature (55-75 °c) and time (20-40 min) and drying temperature (40-70 °c) on the chemical composition (brix, ph, sugars and vitamin c) and the microbial properties of apple leather investigated. the results showe...

Cow leather is a widely used material. Even though durable, it causes ethical, social, and environmental issues. The synthesis of vegan leather, using symbiotic culture bacteria yeast (SCOBY), could be explored for an alternative to cow leather. Presently, there are limited studies on the different substrates produce this method. Hence, study aimed plant-based various such as black tea, green c...

Polyurethanes as one of the leading elastomers are explored in academics well industry. These segmented macromolecules having alternate sequence soft and hard segments. Structure-property correlation between these segments has been extensively reported literature. PUs used widely coatings, varnishes, glues, foams, adhesives, sealants, automobile parts, synthetic leather etc. Its application bio...

The use of enzymes for hair loosening in leather processing provides a cleaner option. However, there is need to improve the efficiency of these unit operations involving bioprocess by way of process intensification techniques, such as, the use of ultrasound. In this paper, the use of ultrasound has been studied in native enzyme papain (A) based hair-loosening system and compared with commercia...

The non-homogeneity in mass and geometrical parameters of leather one type manufacturing method is experimentally investigated analyzed. Experimental studies were conducted on semi-finished cattle products a combined batch chrome kips from technological batch. results the experiments showed that with batch, between thickness product, there moderate correlation studied physical average error coe...

AIMS To assess how a 10 year extension of the follow up period affected cancer incidence in the Swedish leather tanning cohort. METHODS A cohort of 2027 tannery workers (of which 482 were women) who had been employed for at least one year between 1900 and 1989 at one of three Swedish leather tanneries, was established. The start of observation varied between 1958 and 1966 for the three plants...

AIMS To examine the effect of subatmospheric steam treatment on total viable counts (TVCs) on bovine hide and on the quality of derived leather. METHODS AND RESULTS Pieces of bovine hide were heated to 75 degrees C (+/-2 degrees C) (n = 3) or 80 degrees C (+/-2 degrees C) (n = 3) for periods of 1, 10 or 20 s by the application of steam at subatmospheric pressure in a laboratory scale apparatu...
