A review on the preparation of the activated carbon from agricultural waste material is presented. The physical properties such as proximate and ultimate analysis of agricultural waste material were reviewed. The chemical compositions such as cellulose, hemicelluloses and lignin contents were also discussed. The effects of various parameters on the preparation such as carbonization and activation temperature, time, types of activating agents and impregnation ratio were reviewed. Various physical and chemical processes for the activation of the agricultural residues and their effects on the textural properties such as surface area and pore volume were discussed. The low cost, renewable and relatively less expensive of the agricultural waste were found to be efficiently being converted into wealth. The uses of activated carbon derived from agricultural residues in many fields were evidently proven in the review. The reaction kinetic modeling on the pyrolysis and activation of agricultural wastes were also reviewed.

Natural antioxidants are widely distributed in food and medicinal plants. These natural antioxidants, especially polyphenols and carotenoids, exhibit a wide range of biological effects, including anti-inflammatory, anti-aging, anti-atherosclerosis and anticancer. The effective extraction and proper assessment of antioxidants from food and medicinal plants are crucial to explore the potential antioxidant sources and promote the application in functional foods, pharmaceuticals and food additives. The present paper provides comprehensive information on the green extraction technologies of natural antioxidants, assessment of antioxidant activity at chemical and cellular based levels and their main resources from food and medicinal plants.

Experimental design of supercritical fluid extraction – A review

Garlic has been a favorite additive in food for many years in various cultures. It is known that garlic
(Allium sativum) possesses antimicrobial, antiprotozoal, antimutagenic, antiplatelet and antihyperlipidemic
properties. Allicin, a thiosulfinate extract of garlic, has been presumed to be a very strong antioxidant. High
performance liquid chromatography (HPLC) analysis of raw garlic extract was not conclusive to determine
allicin’s presence. However, using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging methods to determine
the antioxidant activity of raw garlic extract shows a color change from deep violet to yellow, indicating
antioxidant activity. Thus, raw garlic can be a source of antioxidant based on the results of the DPPH scavenging
analysis.

Biodegradable poly(D, L-lactide-co-glycolide) (PLGA) and PLGA-based polymeric nanoparticles are
widely used for sustained release of protein and peptide drugs. These formulations are usually prepared
by water/oil/water (W/O/W) and solid/oil/water (S/O/W) double emulsion solvent evaporation method.
Other methods of preparation are nanoprecipitation, emulsion solvent diffusion and salting-out. This
review attempts to address the effects of PLGA molecular weight, lactide to glycolide ratio, crystallinity,
hydrophilicity as well as nanoparticles preparation variables (e.g., homogenizer speed, surfactants
nature and concentration) on the size, morphology, drug encapsulation efficiency and release profile of
PLGA mico/nanoparticles. The current knowledge of protein instability during preparation, storage and
release from PLGA micro/nanoparticles and protein stabilization approaches has also been discussed in
this review.

The locally available rice husk is found to provide a good alternative source of highly active silica for the synthesis of zeolites. The present synthesis of zeolite Y using seed and feed gel method yields maximum crystallinity and rich in zeolite Y and which shows the absence of other impurities. This compared with preparation of zeolite Y seeding and without seeding ethods using commercial silica which yields a mixture of zeolite Y and P.
