Refractance Window Drying and Its Applications in Food Processing
And pressure in this experiment provide the data basis for the future simulation calculation making the considered factors more comprehensive and the results closer to the real situation. Fresh and reconstituted juices were evaluated for vitamin C, titrable acidity and sensory characteristics. The reconstituted juice was found slightly acceptable by taste panel.
Although the drying period may be prolonged, low-temperature drying methods, such as freeze drying, are recommended for drying meat products as it prevents microbiological and biochemical degradation . A drying mechanism with a temperature that does not affect the meat’s physicochemical, Refractance Window Dryer nutritional, or sensory quality with sufficient drying time should be chosen. Fresh meat is a rich source of protein and it is very fast in spoilage. Thus, people from all over the world have come up with ways to preserve and enhance the flavors of meat by drying the meat.
It should also be noted that the processing of fresh meat into dry meat causes biochemical changes. This changes in protein, lipid, carbohydrate, vitamin and minerals of the meat. Nevertheless, there are still challenges in ensuring the quality and safety and dried meat products that need to be addressed. Application of omics approaches has been explored and studied to combat the challenges, importantly in assessing the meat characteristics.
Of 70 ° C for 18 hours, white copra was produced with 7% moisture content. As 409.1â°C can be achieved using just 5âW of electrical power. For simplicity and safety, a functional test of the VLM with water as propellant has been conducted in the laboratory.
Potential of bacteriocins from lab to improve microbial quality of dry -cured and fermented meat products . Fitting the results by second-order equations and modelling by Response Surface Methodology allowed predicting optimum conditions. Epicatechin and glycosylated quercetin were the major microencapsulated flavonoids. Microparticles showed satisfactory antiradical power and stability at 5 °C or under simulated gastrointestinal conditions, thus they may be used to formulate new foods or pharmaceuticals. Optimization of a pharmaceutical freeze- dried product and its process using an experimental design approach and innovative process analyzers. Were examined in terms of the Deal and Grove model for oxidation of silicon.
Evaporate is carried away by mechanically boosted airflow. The transfer of infrared energy through the transparent sheet slows as the product loses moisture, creating a controlled drying process that retains nutrition, flavor, color and aroma. Drying process of mango was carried out using RW drying, freeze drying, drum drying, and spray drying. Results showed that the color of RW-dried mango powder and reconstituted mango puree were comparable to the freeze dried products, but were significantly different from drum dried , and spray dried counterparts. The bulk densities of drum dried and RW-dried mango powders were higher than freeze dried and spray dried powders. There were no significant differences between RW and freeze dried powders in terms of solubility and hygroscopicity.
The RW dryer in this study demonstrated up to 70% energy efficiency (C. I. Nindo, Feng, et al., 2003). Consequently, if it is considered that during the drying process there is a gradual increase in temperature, the following four events could be generated in co-occurrence or in a combination of them. Second, the encapsulation matrix with carrier material had a protective effect during the drying process independently of the processing temperature. Third, during the RW drying, the energy transfer is carried out by conduction, radiation and, to a lesser extent, convection50. Natural drying procedures, such as sun, shadow, and wind drying, are low-cost and ecologically benign.
The traditional meat product of Malagasy or the Kitoza is a sun-dried and smoked meat strip that is important in the native diet. A study has investigated the microbial properties of the Kitoza samples obtained from various local productions in Madagascar . It was found that, in most of the samples, the two most dominant populations are the LAB and coagulase-negative staphylococci, with average microbial count ranging from 6 to 7 log cfu/g. Despite obtaining the samples from the local manufacturer with subpar hygienic practices, no common Salmonella, Clostridium perfringens, and Bacillus cereus contamination were observed, with a very rare occurrence of L. Aureus has been found routinely higher in salted-dried meat products as compared to salted-smoked products. The moisture, protein, fat and salt content were observed to vary on average, with higher moisture content were determined in smoked kitoza than the dried ones.
Could increase the geographic area and timeframe in which persimmon growers... The dhurrin content of these two varieties, even in the young phase, allows the use for grazing of the regrown, which have good bunching. Was chosen so as to verify the new testing methodology.

Kinetic studies on batch cultivation of Trichoderma reesei and application to enhance cellulase production by fed-batch fermentation.
Based on Peter and Shylaja , spice is the various parts of the plant, except leaves, that have been dried . These plant parts give flavors to the food it is added into and are sometimes pungent. On the other hand, herbs can be defined as the dried leaves of fragrant plants that are used to flavor and odorize meals. The plant stems and leaf stalks are frequently traded separately from the leaves .
The above is consistent with the phenomena aforementioned, where it is stated that cell death can be caused by the migration of water from the microorganism to the environment. Additionally, the technique must guarantee the survival of the probiotic and a low moisture content for the stability of the product22. An alternative in drying technologies that has not yet been explored for probiotic encapsulation is the Refractance Window drying . The RW is a technique used for concentrating and drying solutions and purées that allows obtaining a product in the form of a flake or a film23. In the RW drying, the solution or purée is placed on a transparent polyester film, known as Mylar® , which is in contact with hot water (95–98 °C). Radiation allows the product to dry quickly due to low resistance to the thermal conductivity of the film, which makes drying by RW an alternative for thermosensitive products such as probiotics.
And short-time continuous process to dry delicate, heat-sensitive products. Drying takes place at atmospheric pressure to retain product color, avour, aroma and nutritional content. Product quality is comparable to and, in some instances, better than that achieved by freeze-drying. This is done at signicantly less capital and energy cost. Gemtech Band or Apron dryer is a type of industrial drying equipment that is used to dry a wide variety of materials. It typically consists of a long, metal belt or apron that is passed through a series of dryer sections, each with a different temperature and humidity level.
Mathematical modeling of ethanol production in solid-state fermentation based on solid medium' dry weight variation. Instant mashed potatoes with processing of secondary starch-containing raw materials are given. Efficacy of different methanolic plant extracts on anti-methanogenesis, rumen fermentation and gas production kinetics in vitro. Based on the concept of coloring food with food, the powder is created from edible, plant-based raw material. Similarly, de Junqueira et al. found sorbitol as the finest osmotic agent, with the most significant water loss and the minimum gain of solid.
