“…The analyzed samples coincide with the wave number of 700 cm −1 , and the intensity of the absorption band is dependent on the proportion of ingredients of a given sample [ 46 ]. In this area, we can observe a delicate shift to maximum of absorption to shorter wave numbers for samples with a higher content of raspberries at the levels of 60% and 70% and with maltodextrin as carrier at the levels of 40% and 30%, respectively.…”

In the paper, an attempt was made to use methods of artificial neural networks (ANN) and Fourier transform infrared spectroscopy (FTIR) to identify raspberry powders that are different from each other in terms of the amount and the type of polysaccharide. Spectra in the absorbance function (FTIR) were prepared as well as training sets, taking into account the structure of microparticles acquired from microscopic images with Scanning Electron Microscopy (SEM). In addition to the above, Multi-Layer Perceptron Networks (MLPNs) with a set of texture descriptors (machine learning) and Convolution Neural Network (CNN) with bitmap (deep learning) were devised, which is an innovative attitude to solving this issue. The aim of the paper was to create MLPN and CNN neural models, which are characterized by a high efficiency of classification. It translates into recognizing microparticles (obtaining their homogeneity) of raspberry powders on the basis of the texture of the image pixel.

“…Among the important components of the tuberous roots of the dahlia is inulin (Arenas et al, 2011;Ciobanu et al, 2016), a storage carbohydrate that has a wide nutritional and pharmaceutical importance (Melanie et al, 2015), due to its prebiotic activity, and constitutes an effective support treatment for acute and chronic intestinal disorders (Nsabimana and Jiang, 2011), also improves the bioavailability of calcium and magnesium, with promising evidence in the reduction of cancer risk, reinforcement of the immune response and protection against intestinal disorders, has a low caloric value, decreases the risk of high concentrations of triglycerides, in addition to favoring the development of beneficial bacteria in the colon (Santana et al, 2016;Başaran et al, 2017). It is for all the above, that the objective of the present investigation was to evaluate the physicochemical quality, antioxidant capacity and nutritional value in tuberous roots of some wild dahlia species (Dahlia spp.…”

“…However, Castro et al (2013) indicate a content of 35 g 100 g -1 in roots of yacon (Smallanthus sonchifolius), which is lower than the concentrations obtained in this work. The modification of pH (5 and 10) of the extraction medium can alter the inulin yield in dahlia, as indicated by Melanie et al (2015) with values between 29.35 and 43.77%, respectively. Likewise, the inulin content in collections of wild dahlia (Dahlia coccinea) ranged between 23.9-42.5 g/100 g (Santana et al, 2016), however, when these plants were cultivated, their concentration increased significantly.…”

The aim of this research was to evaluate the physicochemical quality, antioxidant capacity and nutritional value in tuberous roots of some wild dahlia species. The experiment was carried out in the Department of Plant Science of the Autonomous University Chapingo, Mexico. Plants were established in a randomized complete block design with five replications. The total soluble solids (TSS), titratable acidity (TA), vitamin C (VC), total phenols (TP), antioxidant capacity (AC), inulin and its proximate composition were evaluated. Among the materials analyzed, the most outstanding wild species were Dahlia campanulata, D. coccinea and D. brevis, where D. campanulata stood out for its concentration of VC (0.05 mg 100 g-1), AC (1.88 mg VCEAC g-1), inulin, DM and TC (72.25, 24.38 and 88.37%, respectively), however, the inulin content was similar to D. coccinea (66.17%), which was also outstanding with respect to the content of TP (1.74 mg GA g-1). Likewise, D. brevis presented the highest values of RFi (5.49%) and A (78.42%). According to our results, the tuberous roots of wild dahlia species can be used as food, as well as being a source of selection of traits of nutraceutic interest for genetic improvement. ********* In press - Online First.

“…In addition, the inulin characteristic bands at ∼1130–1030 cm −1 were correlated to the stretching vibrations of the C–O, C–O–C groups and ring vibrational modes in the composition of cyclic structures. The deformations of the CH, CH 2 and OH groups of the fructose ring were observed at ∼1330–1400 cm −1 . In HI, the presence of inulin was detected by specific bands at 1040–1140 cm −1 (related to the fructose ring of inulin) suggesting weak interactions with the polymer network.…”

BACKGROUND: Hydrogels are materials with great potential in agricultural applications. Biodegradable hydrogels are used as preparations, for example to increase the substratum water capacity, and improve soil structure or agrochemical-controlled release. This work aimed to develop biodegradable hydrogels based on chitosan, gelatin and polyvinyl alcohol (PVA) for releasing inulin isolated from Dahlia tubers to induce protection in chili plants against Phytophthora capsici. The hydrogels were characterized by water absorption capacity, Fourier transform infrared (FTIR), scanning electron microscopy (SEM) and stereomicroscopy microscopy, and degradation capacity using the soil burial test with sterile and inoculated soil. RESULTS: This work demonstrated the ability of a fabrication process in the preparation of gelatin-chitosan-PVA hydrogelsfor potential agricultural applications. The hydrogels showed a dense, tridimensional, interconnected and reticulated structure that was more evident in the hydrogel loaded with inulin. The hydrogels showed a water absorption capacity of ≤12 times its mass. FTIR and light microscopy demonstrated that the hydrogels were biodegradable. The percentage of degradation of hydrogels in inoculated soil was higher than in sterile soil using the soil burial test. Hydrogel loaded with inulin was found to be capable of inducing resistance in chili plants against Phytophthora capsici. CONCLUSION:The hydrogels prepared for the described methodology have great potential for use in the agricultural sector as a reservoir for agrochemicals and inductors in plant resistance treatments. Furthermore, the hydrogels were proven to be biodegradable, offering a promising tool in crop protection. Surface morphology of hydrogelsThe hydrogels have a polyhedral irregular shape. Figure 5(a) shows that the surface morphologies of the hydrogels revealed the formation of a reticulate heterogeneous network. When the hydrogel was loaded with inulin and freeze-dried again, inulin aggregates between the macro channels of the structure [Fig. 5(b)]. Biodegradation test of the hydrogelThe degradation of the hydrogels (H and HI), that were buried in the sterile and inoculated soil were monitored after 7, 14, J Chem Technol Biotechnol 2019; 94: 3495-3504
