The nutritional composition of Spirulina platensis has been studied extensively, especially its proteins, amino acids, vitamins and mineral content. However, research on protein properties, including techno-functional remains scarce. Therefore, S. proteins were extracted concentrated to produce a concentrate (SpPC), which was characterized by physicochemical properties. Response surface methodology (RSM) applied evaluate the influence two variables, pH SpPC concentration, properties SpPC,...
This study examined the behavior of semi-continuous hydrolysis process corn stover (CS) in subcritical water, focusing on effects varying pH levels (1, 2, 4.5, 7, and 8) temperatures (113, 130, 170, 210, 226°C). The results showed that at 170°C 1 was able to recover highest amount phenolic compounds (76.82 mg Gallic Acid Equivalents g⁻¹), consequently demonstrating antioxidant activities by Ferric Reducing Antioxidant Power (FRAP) (423.85 μMol TEAC g⁻¹) 2,2-diphenyl-1-picrylhydrazyl (DPPH)...
Polyhydroxybutyrate (PHB) has been considered as packaging material in many recent applications due to its high crystallinity, biodegradability, low interaction with food matrix and favorable barrier mechanical properties. Although the incorporation of antimicrobial agents structure may control surface microbial contamination foods, they can affect film In this study, eugenol-loaded PHB films were prepared using a solvent casting technique, which subsequently exposed biodegradation study for...
This study evaluated the Chia (Salvia hispanica L.) oil composition in terms of fatty acids (FA), sterols, acylglycerols and oxidative stability obtained via subcritical n-propane fluid extraction (SubFE-propane), different temperatures pressure conditions, as compared to Bligh & Dyer (BD), Soxhlet (SE) Folch (FLS) extractions.Total lipid varied from 23.25 30.21% best yield was by both SubFE-propane at 45 °C 12 MPa (A).α-Linolenic acid (18:3n-3) most abundant FA provided results for sum n-3...
The distinctive topology of pores and cavities zeolites plays a key role in several applications including catalysis, adsorption, ion exchange, where confinement effects are significant can affect the selectivity, stability, reactivity catalytic processes. In this study, effect on adsorption acetic acid H-ZSM-5, H-Beta, H-Y, H-MOR was evaluated by means thermogravimetric analysis coupled with Fourier Transform Infrared (TG-FTIR) spectroscopy density functional calculations, electron quantum...
The present study aimed to optimise the microencapsulation of Lactobacillus acidophilus La-05 by spray drying, using soy extract and maltodextrin as encapsulants. Air inlet temperature, maltodextrin/soy ratio feed flow rate were investigated through Central Composite Rotational Design (CCRD). Probiotic viability increased with increasing proportion extract. Temperature had a negative effect. Particle diameter ranged from 4.97 8.82 μm, water activity 0.25 0.52 moisture 2.30 7.01 g.100g−1...
Objective: This paper investigates the impact of carbonation and sulfuric acid attack on concrete pipes with chitosan addition. Theoretical Framework: The structures results in a decrease durability service life such as sewage oil wells represents substantial environmental social concern. ...
The use of araucaria pine nut shell in polymer composites may increase the value and help protec (Araucaria angustifolia) itself, which is an endangered species. aim this work to study influence size fiber on mechanical properties made polyurethane derived from castor oil. Composites with different contents were manufactured dried untreated sieved through 30 50 mesh sieves (0.6 0.3 mm, respectively). shaped by mixing components followed hot pressing. Properties such as density, water...
