This study aimed to develop nutritious, gluten-free bread with high quality characteristics using a mixture of chickpea, carob and rice flours as substitutes wheat flour. To optimize the formulation, Box-Behnken experimental design was conducted evaluate effect corresponding flour blend addition, proofing time water amount addition on physicochemical, technological sensory properties obtained formulated bread. The optimized formulation calculated contain 70% 100% water, 40 minutes. produced...
Smooth-hound fillets were coated with skin gelatin extracted from the of same fish. The coating solution was enriched garden cress seed extract (GCSE) at 0.67 mg/g gelatin. Analysis phenolic profile revealed that quinic acid (844 µg/g extract) major compound, likely to participate along other phenolics in enhancing preservative capacity GCSE-gelatin coating. Interestingly, psychrophilic/mesophilic bacteria, MDA equivalent, TVB-N and FAA contents samples significantly reduced compared...
The current study evaluates the effect of both aqueous and alkaline extraction methods on physicochemical, structural, functional, antioxidant properties dietary fibers (DF) from male date palm flowers (MDPF). DF extracted by alkali treatment (ADF) display a higher content as well lower protein lipid than resulting watery (WDF). scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction show that contributes to slight modification structural characteristics ADF...
The main objective was to investigate the effect of ultrasound-assisted osmotic dehydration (UOD) pretreatment on kinetics and physicochemical properties pomegranate seeds using a response surface methodology, in order optimize process. Quality attributes were estimated through assessment physical thermal characteristics. Results showed good correlation experimental values with model. optimum conditions used for UOD (OD) found be 240 min, 60°Brix, 41°C, 29°Brix, 50°C, respectively. led...
The aim of this study was to assess the nutritional properties male date palm flower (MDPF) via determining its mineral, amino acid and bioactive compounds profiles investigate antioxidant antibacterial activities in order prove possible use as a healthy potential natural source human dietary diets. Results showed that MDPF is an excellent minerals especially regarding high potassium phosphorus contents (2684.23 318.66 mg/100 g, respectively). Moreover, acids profile considerable amounts...
Gelatin derived from marine by-products could be an interesting alternative to classic mammalian gelatin. The pretreatment and extraction conditions influence the size of resulting peptide chains therefore their techno-functional properties. Thus, it is important optimize production process get a gelatin for appropriate applications. Skin was done by microwaves or oven-drying extracted dried spray- freeze-drying. Freeze-dried untreated skin (FGUS) had highest yield (10.40%). proximate...
Cold-pressed moringa, milk thistle, and jujube seed oils were investigated in terms of their characteristic profiles, thermal properties, oxidative stability. The findings proved that the extracted characterized by high nutritional values, which encourages use various fields. Results showed significant differences between obtained oils. Overall, oil exhibited best quality parameters, with acidity equal to 0.762 versus 1% for moringa thistle Milk absorbance UV-C (100–290 nm), UV-B (290–320...
This study aims to elucidate the effect of male date palm flower (MDPF) incorporation in dough properties and biscuit characteristics. Farinograph analysis demonstrated a progressive increase water absorption (56.85%–61%) stability (1.88–20.25 min) with increasing MDPF quantity due its wealth dietary fiber. Biscuit formulations were prepared using 3, 6, 9% powder evaluated for their physico-chemical, textural, sensory properties. The results have shown significant (p < .05) fiber...
This study aims to investigate the effect of application an ultrasound pretreatment on physicochemical, surface, thermal, and functional properties two extracts from male date palm flowers. The obtained were compared based their structural properties. It was proved that sonication has modified significantly (p < .05) extract's characteristics. protein yield, essential amino acid content solubility improved (29.61%, 29.22 g/100 g protein, 91.1% for native sample against 35.26%, 41.04 100%...
This work aimed to study the osmotic-dehydration kinetics of pomegranate seeds (PSs) (Punica granatum L.) using three fruit (apple, bitter orange and grape) juice concentrates as osmotic solutions (OSs) (ratio (1/4) m/v, 55° Brix, at 50 °C). The osmodehydration time, pomegranate-seed water loss, solute gain weight reduction were determined during process. equilibrium time periods 20, 60, 80 60 min for sucrose solution, bitter-orange, apple grape concentrates, respectively. physico-chemical,...
This study investigates the influence of polyol compounds (sorbitol and erythritol) on osmotic dehydration process pomegranate seeds. The efficacy was estimated based determination water loss, weight reduction, solid gain, effective diffusivity also through a comparison results obtained between sucrose solutions. Response surface methodology used to optimize process. Quality attributes seeds were determined assessment physical (texture color) characteristics. innovative research applies...
Traditional sun-dried merguez is an authentic Tunisian dried sausage made with a large number of spices and herbs, which was reformulated in this study camel meat hump fat as the artisanal process. This research studied physicochemical, microbiological, chemical compositional changes that occurred fresh (FCM) after 12 days drying to achieve traditional (DCM). The results showed significant weight loss (54.1%), well decreases pH (5.20–4.97), moisture (60.5–12.3%), water activity...
Chickpea protein concentrate (CPC) was used in the preparation of edible bio-films. Glycerol and sorbitol, with a different ratios, were as plasticizing agents. Physico-chemical, microstructure, mechanical properties CPC-based biofilms plasticized glycerol (G100), sorbitol (S100), mix (G50/S50) investigated. G100 showed highest hydrophilicity, solubility, lowest thickness compared to S100 G50/S50. The analysis revealed that possessed elongation at break tensile strength. All observed...
