“…6 a, where L* represented the brightness difference, a* represented the red-green degree, b* represented the blue-violet degree, and ΔE* was used to evaluate the overall color change. Compared with the fresh sample, the L* value on the surface of dried ginger increased, indicating that the brightness of dried ginger was higher than that of fresh, which was due to the reduced water content of the sample after drying, leading to increased brightness (Malvandi et al 2022). In general, the surface L* value was the lowest, the a* value was the largest, and the ΔE* value was the smallest at the drying temperature of 30 C.…”

In this study, direct-contact ultrasonic-infrared combined drying method was used to dry the ginger, including the water loss process, color difference, water migration law, gingerol content, volatile components and antioxidant activity of ginger under different ultrasonic frequencies, drying temperatures and slice thicknesses. The results of low field nuclear magnetic resonance (LF-NMR) and gas phase ion migration chromatography (GC-IMS) analysis showed that compared with single infrared drying, ultrasonic combined with infrared drying accelerated the free water migration rate, shortened the drying time (from 280 min to 160 min), and reduced the loss of gingerol and volatile components in ginger. After ultrasonic intervention, the natural active ingredients and antioxidant activity of the samples were significantly increased (p < 0.05). The results of weighted comprehensive scoring showed that the infrared temperature of 50 °C and the ultrasonic frequency of 21 KHz were the optimal parameters for the direct-contact ultrasound-infrared combined drying of ginger slices, and the overall quality of ginger slices was the best under these conditions. This drying technology has certain reference significance for the drying process of ginger slices.

“…90% of bioethanol produced in the US uses the corn dry-grind technique, which also yields valuable co-products (RFA, 2022). All forms of dried distillers grain (dried distillers grains (DDG), wet distillers grains (WDG), dried distillers grains with solubles (DDGS), and condensed distillers solubles (CDS)) are major byproducts of bioethanol production in terms of quantity and economic value (Malvandi et al, 2022). Figure 3 shows the different types of distillers grains produced in 2021, with 49% of DDGS and 29% of WDG (RFA, 2022).…”

The aquafeed industry faces many challenges, including reducing the cost of feed by reducing the quantity of fish meal and soybean meal and researching to replace them with other ingredients lower in cost. Furthermore, new low-cost feeds must improve growth and feed utilization while also ensuring fish health. During the past few decades, researchers have shown one of the low-cost and with appropriate nutritional value alternative protein sources to replace fish meal (FM) or soybean meal (SBM) is dried distiller’s grains with solubles (DDGS). Recently, the production of grain-based ethanol as a fuel additive has been increasing as the demand for biofuel has increased, and lessening dependency on fossil fuels has resulted in a dramatic rise in the amount of grains used for ethanol. DDGS are the primary co-product of dry-grind fuel ethanol plants. DDGS has the advantages of having high protein, fat, phosphorus, yield, and low cost. These valuable particles attributed to DDGS have raised controversy amongst feed nutritionists as to how they can proficiently replace fish meal or soybean meal. It has been discovered that DDGS can be replaced with fish meal or soybean meal without affecting growth. Therefore, the present review discusses the effects of dietary DDGS application in the fish feed formulation, the best dietary presence, the possible advantages in fish health, nutrient retention, and the economic benefits of DDGS application in Aquafeeds.

El objetivo fue determinar la cinética de secado del maíz (Zea mays L), variedad Guagal mejorado. Se realizaron con tres muestras de materia prima a temperaturas no controladas entre 60 °C – 80 °C durante 12 horas, seguido por el proceso de cinética de secado en una estufa a 104°C durante 24 horas. Las muestras iniciaron con pesos de 8.09 g; 10.02 g; 11.16 g respectivamente con una humedad inicial de 22.13 % y se obtuvo una humedad final de 0,53 %; 0,7 %; 0,61 %. Las variables medidas incluyeron la humedad en base seca, total y en equilibrio, el flujo de calor, la cantidad y la eficiencia de calor, y la velocidad de secado. Se determinó que la velocidad de secado a mayores temperaturas favorece a la transferencia de masa y energía. Se estableció que el modelo de Henderson y Pabis fue el que mejor se adaptó a los datos experimentales obtenidos en el proceso de cinética de secado a 104°C por 24 horas R2 = 99,798%; mientras que el modelo de Page fue el que mejor se adaptó a los datos obtenidos durante la deshidratación a 60-80°C durante 12 horas R2 = 99,881 %. Esto sugiere que se pueden obtener mejores resultados de secado y deshidratación con la variedad de maíz INIAP 111 Guagal mejorado si se considera el establecimiento de la temperatura adecuada y el tiempo de procesamiento. Palabras clave: Cinética, secado, maíz, modelo matemático, harina de maíz.
