<p>We previously produced tannase from <em>Aspergillus niger</em> using solid state medium. In the present study the enzyme used cashew apple juice. The aim this research was to know effect of tannase on chemical parameters of cashew apple juice. The concentration of tannase used was 0%; 0.02%; 0.04%; 0.06%; 0.08% and 0.1% (v/v). The chemical properties of the juice produced by enzymatic method were compared with the juiced produced through high temperature treatment (100<sup>o</sup>C).  This research showed that the addition of 0.1% of tannase enzyme provide the best product according to the lower content of tannins than the content of tannins in the juice produced with high temperature treatment. The tannase treatment did not change the vitamin C content, content of protein and pH. Meanwhile, high temperature treatment decreased the content of vitamin C and protein.</p>

And Chemical Properties

Cashew apple juice (CAJ) is one of the feedstocks used for biofuel production and ethanol yield depends on the physical and chemical properties of the extracted juice. As far as can be ascertained, information on physical and chemical properties of South African cashew apple juice is limited in open literature. Therefore, this study provides information on the physical and chemical properties of the South African cashew apple juice. Physicochemical characteristics of the juice, such as specific gravity, pH, sugars, condensed tannins, Vitamin C, minerals, and total protein, were measured from a mixed variety of cashew apples. Analytical results showed the CAJ possesses specific gravity and pH of 1.050 and 4.52, respectively. The highest sugars were glucose (40.56 gL−1) and fructose (57.06 gL−1). Other chemical compositions of the juice were condensed tannin (55.34 mgL−1), Vitamin C (112 mg/100 mL), and total protein (1.78 gL−1). The minerals content was as follows: zinc (1.39 ppm), copper (2.18 ppm), magnesium (4.32 ppm), iron (1.32 ppm), sodium (5.44 ppm), and manganese (1.24 ppm). With these findings, South African CAJ is a suitable biomass feedstock for ethanol production.

Background: Cajuína is obtained through clarification of cashew apple juice (Anacardium occidentale L.), a non-diluted and non-fermented beverage, which is prepared from the edible part of the pseudo-fruit. Objective: This study sought to identify and quantify phenolic compounds, determine vitamin C content, total flavonoid content, and the antioxidant activity of two commercial brands of clarified cashew apple juice (cajuína) produced in Piauí, Brazil. Methods: Spectrophotometric and high performance liquid chromatography were used. Results: A high vitamin C content was found mainly in brand A. A high total phenolic content was observed in brand A, and there was no significant difference in flavonoid content between the two brands. Cajuína had high antioxidant activity, which was confirmed by two methods. The highest value was found for brand A by the DPPH method. Conclusion: We concluded that this clarified cashew apple juice has a high antioxidant compound content, and it is a functional food.

Cashew apple is not practically used such as cashew nut which is one of most traded agricultural export products from Northern Ivory Coast. This work focus on the use of cashew apple juice as food additive in production of yoghurt. The aim of this study is to evaluate physicochemical parameters of cashew apple juice and its effect on fermentative activity of two lactic bacteria (Lactobacillus delbrueckii subsp bulgaricus and Streptococcus salivarius subsp thermophilus). Various types of yoghurt were formulated with incorporation of different proportions (0%, 5%, 10%, 15%, 25%, 35% and 40%) of cashew apple juice in milk (v/v). Each formulation was fermented with lactic ferment containing the above two lactic bacteria. Effect of juice on fermentative activity of the two bacteria was carried out by pH, titratable acidity with duration of fermentation to obtain 80 Dornic degrees. Results of phytochemical analysis (p<0.05) showed that cashew apple juice have an acid pH with value of 3.96 ± 0.03 and titratable acidity of 0.41 ± 0.01%. This juice contains a high level of moisture (77.48 ± 0.09%) and vitamin C (124.74 ± 1.17 mg/100ml) but a low concentration of reducing sugars (1.46 ± 0.03 g/100ml). The study of effect of cashew apple juice incorporated into milk, showed that the formulations with 5% and 10% improved fermentative activity of lactic bacteria tested. These two formulations (5% and 10%) reduced fermentation time (180 min) compared to control (220 min). This study suggests that cashew apple juice could be a food additive in production of yoghurts as a source of vitamin C and catalyst for fermentation. In perspective, we plan to assess toxicity and shelf of yoghurt with cashew apple juice.

The article substantiates the relevance and necessity of developing mathematical models in foundry production, as well as the problems and prospects of their use. Based on an analytical review of the world literature on foundry production, it was emphasized that in many studies of the authors and literary sources, not enough attention is paid to the development of mathematical models of the technological process of extracting non-ferrous metals from slag and industrial waste. A brief description of the developed technologies for the high-temperature treatment of industrial slags and waste, separation treatment in electric furnaces, and metals extracted from liquid slag is given. During the development and analytical implementation of the mathematical model, the developed technology for extracting copper from slags is presented as an research object. Based on the study of the dynamics of changes in the thermophysical properties of the components as a function of temperature, a mathematical model of high-temperature treatment of slags is compiled. This will allow you to predict the process of processing slags and the results obtained. Also, a mathematical model of the extraction of copper from the slag is compiled, taking into account the chemical properties of metal inclusions in the slag. This serves as the basis for automating the process of extracting copper from slags and waste products.

The Stability

ABSTRACT This study evaluated the stability of cashew apple juice in powder, dehydrated in spouted bed and stored in two vacuum-sealed packages (laminated and plastic) for a period of 60 days. The parameters evaluated in this study were ascorbic acid, carotenoids, moisture, water activity, hygroscopicity, degree of caking, solubility and rehydration. Decreases in the contents of ascorbic acid and carotenoids were observed after 60 days. Moisture content remained practically unchanged during storage, and water activity showed a rising trend in the plastic package. In both packages, the powder showed low hygroscopicity and high caking formation. The solubility in both packages was higher than 90% and the time of rehydration of cashew apple juice in powder in the plastic package increased during storage. Cashew apple juice in powder stored in laminated package preserved better its physical and physico-chemical properties.
