This study aimed to examine the influence of microwave pretreatment (MWP) for 0, 15, 30, 45, and 60 s, ultrasound (USP) 5, 10, 20 min, on drying time, effective moisture diffusivity (Deff), rehydration rate, color indexes (lightness, redness, yellowness), total change (ΔE) eggplant slices during dehydration in a hot-air dryer. The results demonstrated that USP significantly reduced time (higher water loss) (p < 0.05). While, MWP increased Deff values ultrasonic pretreated were considerably higher than those untreated determined by Fick's second law was varied from 5.95 × 10−10 9.56 m2s−1, 1.27 10−9 1.42 samples ultrasound, respectively. Nine mathematical models (Page model, Quadratic Newton Verma Logarithmic Two-term Exponential Wang Singh Henderson Pabis Midilli model) used estimate coefficients following non-linear regression method. showed Page model became most accurate show characteristics compared eight other confirmed with sum squared error (SSE) ranging 0.0014 0.0098. average ratio untreated, microwave-treated, ultrasound-treated 404.6 %, 360.1 438.6 yellowness, ΔE parameters slices. It can be concluded proved retaining surface improving speed MWP. ultrasonically had shorter times, improved values, rates, appropriate appearance.

Effect of ultrasound combined with chemical pretreatment as an innovative non-thermal technology on the drying process, quality properties and texture of cherry subjected to radio frequency vacuum drying

Ultrasonics Sonochemistry, Год журнала: 2024, Номер 108, С. 106980 - 106980

Опубликована: Июль 4, 2024

To obtain high-quality cherry products, ultrasound (US) combined with five chemical pretreatment techniques were used on prior to radio frequency vacuum drying (RFV), including carboxymethyl cellulose coating (CMC), cellulase (CE), ethanol (EA), isomaltooligosaccharide (IMO), and potassium carbonate + ethyl oleate (PC AEEO). The effect of different pretreatments (US-CMC, US-CE, US-EA, US-IMO, US-(PC AEEO)) the characteristics, quality properties, texture, sensory evaluation cherries was evaluated. Results showed that dehydration time energy consumption decreased by 4.17 − 20.83 % 3.22 19.34 %, respectively, contents individual sugars, soluble solid, total phenolics (TPC), natural active substances, flavonoids (TFC), antioxidant properties (DPPH, ABTS FRAP) significantly increased after US treatments (P < 0.05). Moreover, played important role in improving texture surface color retention dried cherries. According analysis, dehydrated pretreated US-CMC exhibited highest overall acceptance, crispness, color, sweet taste lower off-odor, bitter sour compared control other pretreatments. findings indicate is a promising technique for increasing physicochemical qualities rate samples, which provides novel strategy processing cherry.

Impact of ripening stages and drying techniques on the physicochemical and sensory attributes of apple mango chips

Journal of Food Science, Год журнала: 2025, Номер 90(1)

Опубликована: Янв. 1, 2025

Mangoes (Mangifera indica L.) are valued for their rich nutrients, including vitamins A, B, C, carotenoids, and phenolic compounds. However, high moisture content seasonal availability contribute to post-harvest losses of up 50%. To reduce these extend shelf life, drying methods like solar, convective, freeze-drying used, each impacting dried mango quality differently. This study examines how ripening stages affect the physicochemical sensory qualities apple chips, analyzing attributes such as (7.81%-11.50%), protein (2.49%-2.89%), fat (0.78%-1.11%), pH, total soluble solids, color parameters (L* a* values). Results show that solar drying, especially fully ripe mangoes, enhances qualities, with ripe, solar-dried chips receiving highest ratings color, taste, flavor, aroma. emphasizes importance optimizing ripeness techniques improve quality. Although is cost-effective preserves limitations include nutrient loss limited access advanced technologies freeze-drying, in developing regions. The study's focus on mangoes a small, non-trained panel may limit generalizability, suggesting future research could explore additional across more varieties. Larger panels trained evaluators provide broader insights. offers valuable strategies enhancing production marketability. By techniques, industry professionals researchers can product quality, meet consumer preferences, support sustainability, benefiting local farmers global markets.
