This research focuses on the analysis of the chemical component of essential oil of lemon balm. The essential oil of leaves was obtained by extraction. The chemical components of the essential oil of lemon balm were analyzed by capillary GC and GC/MS and 8 substances were identified. The quality of the final product depends heavily on the operation of freeze drying (FD). It was found that essen...

Dried litchi pulp has been used in traditional remedies in China for many years to treat various diseases, and the therapeutic activity has been, at least partly, attributed to the presence of bioactive polysaccharides. Polysaccharide-protein complexes from vacuum freeze-(VF), vacuum microwave-(VM) and heat pump (HP) dried litchi pulp, which were coded as LP-VF, LP-VM and LP-HP, were comparativ...

The objective of this review is to synthesize information available on the feeding value of coffee waste. In the diets of ruminants, waste and by-products of coffee have successfully used 10 to 30%. It has been claimed that the feeding of Coffee leaves extends the lactation period. Coffee pulp (dried or not), coffee hulls (sticky or dried) and coffee grounds (a by-product of instant coffee manu...

The behaviour of different cellulosic fibres during acid hydrolysis has been investigated and the levelling-off degree of polymerisation (LODP) has been determined. The study included a bleached kraft pulp (both never-dried and once-dried) and two dissolving pulps (once-dried). Additionally, cotton cellulose from new cotton sheets and sheets discarded after long-time use was studied. Experiment...

This study examines the sorption of methylene blue on the cheap unconventional bio sorbents, citrus fruits: oranges and lemons. Bio sorbents which was used was: orange and lemon peel, seeds and pulp. The results are compared with results of sorption to mineral sorbents, zeolite clinoptilolite, Pyrolox and Birm. Sorption kinetics and the influence of pH on the sorption of methylene blue on orang...

nanofibrillated cellulose fibers were produced from unbleached kraft pulp of kenaf bast fiber. air dried and vacuum filtrated films of cellulose nanofibers were produced and their density and tensile properties were investigated. kenaf bast fiber unbleached kraft pulp has good potential for production of cellulose nanofibers by microfluidizer; so that the use of kenaf bast fiber unbleached kraf...

In this study, a pulp beating machine was used to premix the pulp fibers with high density polyethylene (HDPE) particles in water. The wet or pre-dried pulp fiber/HDPE mixture was then melt-compounded by a twin screw extruder. For further improving the dispersion of pulp fiber, some mixture was forced to pass through the twin-screw extruder twice. The resulting mixture was compression molded to...

Banana (musa Sapientum var Cavendish) pulp was obtained and drum dried with varied concentrations of prepared cornstarch, skimmed milk powder and sugar. The water activities of the resulting powders were determined and from which the packaging requirement of the free flowing combinations was determined. The dried banana pulp was found to be thermoplastic and highly hygroscopic. The thermosplast...
