Nigeria ranks 2 nd amongst top 10 ginger producers in the world with a production of 691,239 tonnes and its is among best, aroma, pungency high oil oleoresin content as distinct features. The most important form commercially dried because it can be further processed industry to powder, oleoresin. T here an increasing international demand for oleoresins, especially alcoholic beverages, ale ginge...

Effects of different freezing rates and four different thawing methods on chemical composition, microstructure, and color of ginger were investigated. Computer simulation for predicting the freezing time of cylindrical ginger for two different freezing methods (slow and fast) was done using ANSYS (®) Multiphysics. Different freezing rates (slow and fast) and thawing methods significantly (P < 0...

A glycosidically bound fraction was prepared by adsorbing a 80% methanol extract from fresh rhizomes of ginger onto a column of Amberlite XAD-2 resin and successively eluting with ethyl acetate or methanol. Enzymatic hydrolysis of this fraction with an acetone powder prepared from fresh ginger and commercial glycosidase liberated such alcohols as geraniol, 2-heptanol, α-terpineol, nerol, linalo...

This study aimed to determine the essential oil volatile components of ginger and turmeric rhizomes, as well total antioxidant capacity samples according CUPric Reducing Antioxidant Capacity (CUPRAC), ferric reducing potential (FRAP) method free radical scavenging activities standards such BHA, BHT, Trolox were determined using a DPPH method. Essential analysis was also performed on Shimadzu GC...

Ginger spent is the byproduct of spice industries that remove essential oils ginger (Zingiber officinale) for food industry and medicinal purposes. a well known used often seasoning in Indian cuisine. The de-oiled has no specific use mostly goes to waste. Hence, we utilized this industrial waste product efficient synthesis silver nanoparticles with aid UV irradiation from solution 1mM nitrate e...

Acetone was investigated and found to be an appropriate alternative to Triton X-100 as a solvent of essential oils in bioassays aimed to investigate their effects on pinewood nematode (Bursaphelenchus xylophilus) mortality. Therefore it was used as dilution agent to screen the effectiveness of fifty two essential oils against this pest. Thirteen essential oils were highly effective, resulting i...
