Background: Essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. Objective: The antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storag...

The present study investigated the use of waste non-edible oil cakes (Jatropha, Karanja, Neem, and Mahua) as a substrate for the growth of Paecilomyces variotii and dipicolinic acid (DPA) production. Previous researches proved the efficacy of DPA in suppressing certain pathogens that are deleterious to the plants in the rhizosphere. DPA production was statistical optimized by amending non-edibl...

The objective of this study was to evaluate the feasibility of an aqueous process to extract the residual oil from sunflower press cakes using a co-rotating twin-screw extruder. Two different configurations were tested: the expression fromwhole seeds followed by the aqueous extraction, in two successive apparatus or in the same one. For the aqueous extraction stage, the oil yield depended on th...

We demonstrate three potential edible applications of shellac oleogels as (i) a continuous oil phase for preparation of emulsifier-free, structured w/o emulsions (spreads), (ii) a replacer for oil-binders in chocolate paste formulations and (iii) a shortening alternative for cake preparation. Water-in-oil emulsions with up to 60 wt% water were prepared without the need for an emulsifier by simp...

The present study deals with the assessment of antimicrobial activity (antibacterial, antifungal and antiyeast) of bio-oil from Pongamia glabra, Mesua ferrea and Parachlorella spp deoiled cake. The bio-oil from the respective deoiled cakes were obtained via the process of pyrolysis (ambient to 500°C at a heating rate of 40°C/min) in a vertical tubular fixed bed reactor in nitrogen atmosphere. B...

Of the 34 fungal species, isolated from a number of oily substrates, 9 exhibited lipase activity. AU 15, identified as Aspergillus sp., was found to be excellent lipase producer in submerged fermentation and was selected for solid-state fermentation (SSF). Among substrates like oil cakes of coconut, groundnut and sesame, wheat rawa, bombay rawa and soya beans (crushed), wheat rawa showed the hi...

Fungal activity of the essential oil extracted from Cassia tora (Fabaceae) was studied against dermatophytic fungi like Microsporum gypseum. Study of dermatophytes in soil samples collected from Jaipur, was carried out but only 88% samples contained dermatophytic fungi. In screening of the essential oil of Cassia tora the diameter of inhibition zone was found to be 19 mm for Microsporum gypseum...
