No full textA mixed white: red light regime leads to enhanced biomass and lipid production in an indigenous phycobiont Trebouxia corticola in a flat panel photobioreactor
No full textLight intensity and quality are critical in determining the production and composition of
microalgal biomass. Response of an indigenous phycobiont Trebouxia corticola to a mixed light-
emitting diodes light regime (White Light 40: Red Light 60) of 450 μmol photons m− 2 s− 1 was
evaluated in a flat panel photobioreactor. The biomass concentration and productivity, specific
growth rate, and carotenoid content were 1.41–2.37 fold, and superoxide dismutase levels were
1.14–1.29 fold higher than white and red light cultures. The maximum photosynthetic efficiency,
photosynthetic electron transport rate, and non-photochemical quenching values were compar
atively higher than white and red light cultures. The lipid content (35 % w/w), lipid productivity
and the relative eicosapentaenoic acid content of total fatty acid methyl ester were more than
two-fold, four-fold, and 1.28-fold higher than white and red light cultures. A 58.63 % decrease in
carbohydrates, 28 % increase in lipids, significant downregulation of sugar levels, and an upre
gulation of carboxylic acids compared to white light cultures suggested a diversion of carbon flux
towards lipid biosynthesis. The growth-promoting and oxidative stress-protecting glyoxylate and
dicarboxylic acid metabolic pathways were induced. A substantial expression of the linoleic acid
metabolism pathway suggested that lipid metabolism was significantly influenced. These results
suggest that the mixed light regime used in the present study could effectively influence cellular
metabolism leading to simultaneous production of significantly higher biomass and lipid in
T. corticola. The study suggests that phycobionts like T. corticola could be important candidates for
further studies and strengthens the potential of bioprospecting in identifying microalgae with
desirable traits
Deacidification of Coconut Oil Using Different Resins: A Comparative Study
No full textIn the food sector, deacidification of vegetable oil is essential for enhancing edible oil’s stability, quality, and shelf life. It is still
difficult to come up with an efficient deacidification method that makes use of high-acid-value oil to produce edible goods
that are both high-quality and value-added. The present work provides a newly developed, adaptable, and long-lasting ion
exchange deacidification method. Three different ion exchange resins, that is, Amberlite IRA 400 (AMT), Amberlyst A26 (A26 ), and
Dowex WGR-2 (DOX) at different concentrations were assessed to remove free fatty acids (FFAs) by adsorption using a column,
where AMT (85.92%) and A26 (98.02%) showed a good result compared to DOX (75.4%). To further confirm the reduction in the
acid value of the treated oil, multiple methods were used, including FFA measurement by titration, gas chromatography (GC),
high-performance liquid chromatography (HPLC), and attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-
FTIR). All these methods consistently demonstrated a reduction in FFA levels in the oil collected after treatment with resin.
Additionally, to assess the effect of the resin on the oil, various physicochemical parameters were analyzed. It was found that most
of the tocopherols and tocotrienols were preserved, and there was little to no impact on other key quality parameters.
Practical Applications: Our study offers valuable insights into the development of a deacidification technology for removing FFAs
from oil using resins. This environment-friendly method effectively tackles the challenge of high acidity in oils by efficiently
adsorbing FFAs. The use of resins provides an efficient solution while retaining the nutritional properties of the oil, making it
an appealing alternative to traditional methods. This technology holds significant potential for industrial applications, such as
improving the quality and shelf life of edible oils by removing FFA, as well as reducing waste during alkali treatment. Implementing
this technique can help promote better practices in the oil processing industry
Development of Spray-Dried Microparticles Encapsulating Onion Peel Extract Containing Anthocyanin: Optimization, Characterization, and Storage Stability
No full textABSTRACT: This study aimed to evaluate the effect of the spray drying method on the anthocyanin encapsulation from inedible
waste of onions. The spraying conditions for microencapsulation were optimized using the Box−Behnken design with factors such as
maltodextrin (MD %), inlet temperature, and the ratio between MD and anthocyanin extract. The maximum yield of 89.64% ± 0.01,
0.023 ± 0.00 mg/mL, and 0.82 μm ± 0.11 of anthocyanin encapsulation efficiency, antioxidant activity, and particle size was
achieved by 5% MD concentration at ∼130−150 °C. The encapsulated anthocyanin powder (EAP) was evaluated for morphological
tests such as scanning electron microscopy, particle distribution, Fourier transform infrared analysis, and physicochemical tests like
moisture content, solubility, density, and differential scanning calorimetry. Electronic sensing devices, E-nose and E-tongue,
confirmed the aroma and taste profiles of EAP. Finally, 60-day storage study was conducted to obtain information on the stability of
EAP for different temperatures and light conditions
Aqueous extracts and protein concentrate of Tenebrio molitor prolong the lifespan of Caenorhabditis elegans under environmental stress conditions
No full textBackground: Tenebrio molitor, commonly known as the mealworm, is globally accepted and recognized as an edible insect with
a high nutritional profile and potential health benefits. Mealworms are sustainable protein sources for addressing future food
security. This study aimed to investigate the anti-aging properties of mealworm aqueous extracts and protein concentrate
using Caenorhabditis elegans as a model organism.
Results: C. elegans treated with mealworm protein concentrate and aqueous extracts (60 ∼g mL−1) exhibited a significant
enhancement of lifespan by 10–26.4% (P ≤ 0.05) under normal conditions. Stress tolerance survival of the treated nematodes
was improved by 83–91% (P ≤ 0.05) under thermal stress, and an extended lifespan of 1–2 days was observed under UV expo-
sure. Additionally, reactive oxygen species were significantly reduced, with a fold change of 0.54–0.7 (P ≤ 0.05) compared to
control. Structural improvements in nematodes treated with mealworm-derived bioactives included enhanced pharyngeal
integrity, reduced lipofuscin content, lower lipid accumulation and prevention of intestinal permeability. These changes high-
light the role of mealworm protein concentrate and extracts in maintaining cellular health, improving metabolic functions and
mitigating aging-related deterioration. These effects were supported by increased antioxidant enzyme activities (superoxide
dismutase and catalase) and the activation of stress response pathways mediated by hsf-1 and skn-1.
Conclusion: The study demonstrated that mealworm aqueous extracts and protein concentrate possess significant anti-aging
properties and improve stress resilience in C. elegans. These findings highlight the potential of mealworm-derived products
in mitigating age-related health issues, with promising applications in cosmeceuticals and nutraceuticals
Synbiotic pineapple beverage increases life span in Caenorhabditis elegans, ameliorates cognitive impairment, and restores gut microbiome diversity in D‑galactose‑induced aged C57BL/6 mice
No full textThe incidence of age-associated ailments
has increased proportionately with the expansion of
the aging demographic. This study aimed to evaluate
the anti-aging potential of synbiotic pineapple bever-
age formulated with 100% pineapple juice, 1% inulin,
and Lacticaseibacillus rhamnosus ATCC 53103 (10
log CFU) in Caenorhabditis elegans and D-galactose
age-induced mice. The synbiotic juice-treated nema-
todes exhibited a 24.52% increase in their lifespan,
accompanied by lower levels of reactive oxygen spe-
cies and improved structural functions. In vivo stud-
ies demonstrated that synbiotic treatment positively
influences age-induced mice’s cerebellar function
and spatial memory. Additionally, the synbiotic bev-
erage containing 8–10 log CFU of Lacticaseibacillus rhamnosus showed a protective effect against hip-
pocampal neuron damage. The control group dis-
played a higher Firmicutes/Bacteroides (F/B) ratio,
whereas the significantly lower F/B ratio in the dis-
eased groups indicated a reversal of microbial imbal-
ance caused by D-galactose exposure. Furthermore,
the consumption of synbiotic beverage mitigated tel-
omere shortening in aged mice. The results highlight
the anti-aging effects of a pineapple beverage formu-
lated with Lacticaseibacillus rhamnosus and inulin as
a synbiotic intervention. This study suggests that die-
tary interventions incorporating prebiotics and probi-
otics may serve as promising strategy for combating
age-related disorders and promoting healthy aging
