Physicochemical Characteristics of Sangju Traditional Dried Persimmons during Drying Process

The quality of honey are naturally differs depending on its geographical origin and the botanical source of honeydew collected by the bees. These characteristics influence the physical appearance of honey such as its colour lightness and liquid thickness; which then may influence the honey attractiveness to the consumers. The thickness of honey is correlate with its moisture content. The higher the moisture content of honey, the higher the risk of fermentation, thus honey is commonly process before marketed. However, the processing methods may change the nutritional content, original taste and physical characteristics of the honey. This paper reviews the effect of five types of processing methods on the quality of honey; which are the spray-drying process, thermal treatment technique, thermosonication technique, high-pressure processing technique and microwave processing method. Overall, it can be concluded that all processing methods reviewed in this article altered the nutritional quality and physicochemical characteristics of honey. However, the different processing methods may alter the quality of honey differently. This information is very important for consumer to understand the reasons on the variability of honey quality in the market. It also will help the honey industry players to choose the best method in processing their honey and ensuring the best quality of honey can be produce to fulfil the consumers need and satisfaction.

Corneal Collagen

Pioglitazone-loaded PLGA-PEG nanoparticles (NPs) were stabilized by the spray drying technique as an alternative to the treatment of ocular inflammatory disorders. Pioglitazone-NPs were developed and characterized physiochemically. Interaction studies, biopharmaceutical behavior, ex vivo corneal and scleral permeation, and in vivo bioavailability evaluations were conducted. Fibrillar diameter and interfibrillar corneal spacing of collagen was analyzed by synchrotron X-ray scattering techniques and stability studies at 4 °C and was carried out before and after the spray drying process. NPs showed physicochemical characteristics suitable for ocular administration. The release was sustained up to 46 h after drying; ex vivo corneal and scleral permeation profiles of pioglitazone-NPs before and after drying demonstrated higher retention and permeation through cornea than sclera. These results were correlated with an in vivo bioavailability study. Small-angle X-ray scattering (SAXS) analysis did not show a significant difference in the organization of the corneal collagen after the treatment with pioglitazone-NPs before and after the drying process, regarding the negative control. The stabilization process by Nano Spray Dryer B-90 was shown to be useful in preserving the activity of pioglitazone inside the NPs, maintaining their physicochemical characteristics, in vivo bioavailability, and non-damage to corneal collagen function after SAXS analysis was observed.

This study investigated the effect of solar drying on storability and physiochemical and antioxidant capacities of dried tomatoes. Sliced fruit was dried at 45 ± 2 °C for 24 h under a solar tunnel dryer and stored at ambient temperature for 90 and 180 days. Solar drying treatments significantly (p < 0.05) reduced the bacterial and mold load, and eliminated Staphylococcus aureus, S. saprophyticus, and Escherichia coli in all samples. Solar drying treatment reduced the water activity of the dried tomato’s to 0.31 that remained at the same level during storage period 180 days. Storage of dried tomato slices resulted in the decrease of both color and vitamin C content while it increased the total carotenoid, lycopene, phenolic compound content, and antioxidant activity. Furthermore, the principle component analysis (PCA) revealed that solar drying of tomato slices enhanced its physicochemical properties, antioxidant capacity particularly after storage for 90 and 180 days. Interestingly, the solar drying process enhanced tomato slices storage and physicochemical characteristics, that resulted in extending the shelf life by up to 6 months, indicating the great potential application of low-tech solar in food industry and could become an emerging effective post-harvest preservative method for seasonal perishable vegetable and fruit, particularly in developing countries.

Starch has application in several industrial sectors, such as food, textile, paper, pharmaceutical, among other industries. To meet this demand, native starches have been modified by chemical, physical and enzymatic methods. Cassava is the second source of starch. Furthermore, understanding the effects of spray-drying modification on the structural and physicochemical characteristics of its starch is important. Therefore, this study aimed to evaluate the effects of the main interfering factors in the process of spray-drying on the characteristics of cassava starch, aiming at increasing the industrial applicability of this starch. A Central Composite Rotational Design (CCRD) was employed to assess the experimental data. Experimental design included four factorial points, four axial points and three replicates of the central point. The starch concentration ranges from 5 to 11 % and preheating temperature ranges from 54 to 60 °C. Results showed influence of the variable factors on the characteristics of cassava starch. The processing conditions that allowed obtaining pregelatinized starches with higher viscosity at room temperature, higher resistance to hot and agitation, lower retrogradation tendency, and with partial solubility, desired quality parameters for this product were: 6 % of starch concentration (wet basis) and 60 ᵒC of preheating temperature.

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.

Instantaneous Chemical

All the desired properties of cement primarily depend on the physicochemical characteristics of clinker from which the cement is produced. The mineralogical composition of the clinker forms the most important parameter influencing these properties.Optical microscopy provides reasonably accurate information pertaining to the thermal history of the clinker, while XRDA still remains the proven method of phase identification, and bulk chemical composition of the clinker can be readily obtained from XRFA. Nevertheless, all these microanalytical techniques are somewhat limited in their applications, and SEM/EDXA combination fills this gap uniquely by virtue of its high resolution imaging capability and possibility of instantaneous chemical analysis of individual phases.Inhomogeneities and impurities in the raw meal, influence of kiln conditions such as sintering and cooling rate being directly related to the microstructure can be effectively determined by SEM/EDXA. In addition, several physical characteristics of cement, such as rhcology, grindability and hydraulicity also depend on the clinker microstructure.
