Essential oils can be extracted
by various extraction methods such as hydro distillation, steam

ohmic heated hydro distillation has not been reported much elsewhere.
In this study, ohmic heated hydro distillation of four types of
plants; Cymbopogon atratus (Lemon grass), Cymbopogon nardus

The treatment of biological
cells with strong pulsed-electric fields can lead to irreversible
formation of large pores in the cell membrane and thus destroy the
cell and give access to its content. This well-known process of

bacteria in many laboratories. However, few efforts have been made to
utilize the technique on a large industrial scale for the production
of nourishment from food plants. We have built the mobile

Krill oil (KO) is unique in
contrast to fish oil because the ω-3 PUFAs, particularly
eicosapentaenoic (EPA) and docosahexaenoic (DHA), are almost
exclusively esterified on phospholipids (PL) rather than
triglycerides (TAG) which improves bioavailability and water
solubility. Therefore, the primary aim of this study was to use the
principles of water degumming to separate PL from TAG in KO. Water
was mixed with KO in varying ratios, centrifuged for separation and

tropical climates. This blue-green alga is packed with nutrients. It
has the outer layer made up of polysaccharide which is water-soluble
known as extracellular polysaccharides (EPS), which possess various
biological activities such as antitumor, antiviral, antioxidant and
anticoagulant activity. Extraction of polysaccharides from...

Seaweeds are a rich source of
protein and can contain up to 47% on the dry weight basis. It is
challenging to extract proteins from the raw biomass of seaweed due
to resilient cell-wall complexes. Four species of macroalgae were
used in this study-two brown, Fucus vesiculosus and Alaria esculenta,
and two red, Palmaria palmata and Chondrus crispus. Three treatments
were applied individually to the macroalgal species: (I)
high-pressure processing (HPP); (II) laboratory autoclave
processing...

The aim of this work was to
investigate the potential of PEF technology for green extraction of
microalgal pigments and lipids from fresh Chlorella sorokiniana
suspensions. Efficiencies of PEF treatment and different solvent
systems application to C. sorokiniana were compared to efficiencies
of untreated biomass extraction. Differences in chlorophyll
extraction of untreated and PEF treated C. sorokiniana were only seen
at short extraction times. Beneficial PEF-effect was minimised for
long...

The latest studies on the
extraction of bio-components from plant materials have elaborated on
novel approaches to increase yield. This study evaluated the effect
of vacuum operation parameters on the recovery of protein and
antioxidant compounds from sesame bran. In this context,
vacuum-ultrasound assisted extraction (VU) and vacuum-ultrasound
assisted enzymatic extraction (VUE) methods were carried out, and the
vacuum parameters were investigated using central composite design by
response...

Phenolic acids of oak gall were
extracted using ultrasonic-probe assisted extraction (UPAE) method in
the presence of ionic liquid. It was compared with classical
ultrasonic-bath assisted extraction (CUBAE) and conventional aqueous
extraction (CAE) method, with and without the presence of ionic
liquid. Remarkably, the UPAE method yielded two-fold higher
extraction yield with the presence of ionic liquid, resulting 481.04
mg/g for gallic acids (GA) and 2287.90 mg/g for tannic acids
(TA)...

Steam distillation of essential
oils from Lippia origanoides K. and Lippia graveolens K. leaves plant
material residues that can be valorized. Flavonoids can be
selectively extracted from these substrates using ethanol-modified
supercritical CO2, as attempted in this work. The thymol-rich L.
origanoides chemotype was used to test extraction reproducibility.
The effects of pressure, temperature, time, CO2 mass flow, particle
size, and percent ethanol on the extraction yield of
oleoresin...

Two-step procedure with the
initial aqueous extraction from raw microalgae Nannochloropsis
oculata and secondary organic solvent extraction from vacuum dried
(VD) microalgae were applied for selective recovery of bio-molecules.
The effects of preliminary aqueous washing and high voltage
electrical discharges (HVED, 40 kV/cm, 4 ms pulses) were tested. The
positive effects of HVED treatment and washing on selectivity of
aqueous extraction of ionics and other water-soluble
compounds...

Oleosomes are oil storage
structures in seeds, consisting of triglycerides surrounded by a
protein-phospholipid mixed monolayer. They can be extracted aqueously
together with other seed components such as proteins and soluble
fibers. The co-extracted biomolecules can affect the properties of
the extracts. Nevertheless, it is possible to control the
electrostatic and hydrophobic interactions between these biomolecules
and oleosomes by adjusting the extraction conditions...

Taxanes are natural anticancer
constituents, and the sample preparation from matrix normally depends
on organochlorine solvents. In this study, green and natural
menthol-based aqueous deep eutectic solvent was synthesized and used
for sample preparation for taxanes. Five key parameters were
optimized and the optimal preparation conditions were as follows:
menthol/1-propanol ratio 1:1 (mol/mol), solid–liquid ratio
1:30 g/mL, extraction time 30 min, ultrasonic power
250 W, and...

Developing advanced membranes
with both high permeance and selectivity to enable ultrafast and
efficient separation is a persistent pursuit by materials scientists.
In recent years, diverse ultrathin membranes with nanometer-scale
thickness and unique membrane structures have been developed. These
materials show ultrahigh permeance and excellent selectivity in water
desalination, dye rejection, oil–water purification, and gas
separation applications. Herein, current state-of-the-art
ultrat...

This work was to develop a
cost-effective and sustainable method which included metal chelate
ionic liquid-based aqueous two-phase flotation (IL-based ATPF) and a
two-step precipitation process for purifying bromelain from
pineapple. Firstly, the metal chelate IL-based ATPF with a copper
chelate-functionalized thermosensitive block copolymer
(L64-IDA-Cu(II)) as trapping agent was used as the primary
purification to obtain the L64-IDA-Cu(II)-bromelain complex.
Secondly, the two-step...

Diatom algae can produce
bioactive compounds like fucoxanthin (FX) and ecosapentaenoic acid
(EPA) which are of high demand in pharmaceutical and nutraceutical
industries. Here, the influence of different light regimes in
combination with major nutrients on growth, FX and EPA production by
marine diatom Thalassiosira weissflogii were investigated. Batch
cultures of T. weissflogii were illuminated under blue (BL), red (RL)
and white (WL) light at two intensities. BL regime resulted in
higher...

Effect of superfine grinding on
pectin extraction was investigated. Sunflower heads were grinded into
microparticles of ~50 μm, thus pectin chains were fully
exposed due to cell wall breakdown. A good pectin yield of
14.5 ± 0.36% (w/w) was subsequently achieved at mild
conditions (pH 5.0, 25 °C, 2 h) associated with 0.8%
(w/v) sodium citrate (SC). However, the molecule weight of pectin was
greatly reduced
(Mw = 7.87 ± 0.21 kD...
