Microbial Production of Value-added Products from Cashew Apples - An Economical Boost to Cashew Farmers

Cashew farming- considered as one of the major profit-making agricultural businesses- requires renewed practices in processing its products and by-products for sustained growth. The current review highlights the commercial potential of cashew apples by proposing value-addition strategies through microbial fermentation routes that can help garnering additional profit to the growers. The immense potential of cashew apples and pulp wastes generated after juice-extraction in producing a range of products through the fermentation process such as bioethanol, hydrolytic enzymes, lactic acid, biosurfactants, wine and Feni (an alcoholic beverage) is discussed. Furthermore, a case on the existing Feni-making practices in Goa, India is reviewed, and the need for upgrades in the processing methods for waste mitigation is emphasized. Based on the literature survey and from the gathered knowledge on cashew industries through visits to various cashew farming sites, it is strongly emphasized that a radical improvement in cashew farming is possible only through the adoption of holistic approaches in the cultivation and proper utilization of wastes and its management of cashew apples. Also, Feni production, which is the mainstay of India’s current cashew processing industry, requires major up-gradation in processing methods to improve its quality, marketability, and export potential.

Valorization of Carrot Pomace: UVC Induced Accumulation of Antioxidant Phenolic Compounds

Carrot pomace is the main waste residue obtained during carrot juice extraction. Plant tissues respond to abiotic stresses (i.e., wounding stress and ultraviolet C (UVC) radiation) by accumulating bioactive compounds. Due to the mechanical damage occurring during juice extraction, carrot pomace undergoes extreme wounding stress. In this study, the effects of UVC light (11.8 W m−2, 0–120 min) and storage time (48 h, 25 °C) on the accumulation of phenolics compounds and the antioxidant activity (AOX) of carrot pomace were evaluated. Carrot pomace that was non-treated with UVC (control) showed a 709.5% increase in total phenolics at 48 h. A high correlation of AOX values against total phenolics (R2 = 0.87) was observed, indicating that phenolics were the main contributors to the AOX of the tissue. After UVC treatment, the pomace that was radiated for 120 min with UVC showed an increase (40.4%) in chlorogenic acid (CHA) content. At 24 h, protocatechuic acid and 3,5-dicaffeoylquinic acid, which were not detected before storage, showed accumulation by 166.5 mg/kg and 169.4 mg/kg, respectively, in UVC treated pomace. Chlorogenic acid showed the highest increase (143.6%) at 48 h in the control. Valorization of carrot pomace was achieved by increasing its concentration of antioxidant phenolics through UVC radiation.

The composition of concentrated elderberry juice includes 18 amino acids, in the amount of 4.84 g/100 ml. 7 essential amino acids were detected in the amount of 1.51 g/100 ml. The concentrated juice contained phenols in the quantity of 42.95 mEq gallic acid / gram dry matter and a large number of hydrolyzed tannins. Most polyphenolic compounds were preserved after the juice concentration.

Principles of juice purification

The raw juice as obtained by juice extraction of sugar beet cossettes contains dissolved and insoluble impurities (nonsugars) which need to be removed as much as possible to enable a cost-effective production of the wanted quality of white crystal sugar. The most commonly used purification approach of beet raw juice is the so-called classical liming process. The aim and principles of the different successive process steps in juice purification will be outlined in this paper. The purification principles comprise several chemical-physical reactions of particular nonsugars in the juice which are initiated at first by the addition of milk of lime to the raw juice in preliming and main liming. Through injection of the carbon dioxide produced in the lime kiln in the 1st carbonatation calcium ions precipitate as calcium carbonate, which is then used as filter aid to remove by sedimentation and/or filtration the formed slurry. The remaining surplus of lime salts are finally removed in the 2nd carbonatation which after filtration results in a clear thin juice.

Improved fuzzy logic controller for cane juice extraction

In current days Fuzzy logic plays auspicious role to provide so many choices for many applications which are system control. Fuzzy logic having no. of practical methodologies in soft computing. Sugar making industries are one of the applications using fuzzy logic controller. sugarcane juice extraction is an industry which is highly seasonable. If the supply of sugar cane is irregular then that reduces the efficiency of extractor from cane to mass producing sugar. So, it is necessary to improve the efficiency of extractor, which gives juice from cane billets. For that we must keep up the Donnelly height (or) level of cane is closed to 90cm. Where a methodology introduced to improve the three inputs controller with fuzzy is used to keep up the cane volume (or) level of Donnelly channel. For that cane level must and should always at 90cm. To limited that level (or) height of cane in chute (or) channel was developed by using of tool box in fuzzy logic designer, MATLAB software.

FORMATION OF THE QUALITY OF UNFORTIFIED WINE MATERIALS OBTAINED FROM BLACK ELDERBERRIES

The use of local non-conventional raw materials will allow significantly enriching unfortified fruit wines with ascorbic acid and phenolic substances and make it possible to obtain products with increased biological value. The paper considers black elderberries grown in the forest steppe zone of Ukraine. It has been determined that they contain 12–13% of soluble solids, 6.9–8.1 of sugars, 0.93–1.2% of titratable acids, 33.4–53.1 mg/100 g of ascorbic acid, and 2331–3888 mg/100 g of phenolic substances. The pressing process and its dependence on the method of treating berries have been studied. It has been proved that juice extraction from black elderberries is the highest when they are pretreated with heat at 98±2°C for 3–5 minutes, with 15% of water added. Depending on the treatment method, juices retain ascorbic acid (15.8–33.4 mg/100 g) and phenolic substances (2538–3888 mg/100 g), which indicates their high biological value. Juices like these can be used to improve the biological composition of blended juices and wines. To ferment high-sugar black elderberry must, active dry yeast was used, namely the yeast races EC-1118 of the genus Saccharomyces bayanus (France) and ENSIS LE-1 or ENSIS LE-5 of the genus Saccharomyces cerevisiae (Spain). The musts were fermented for 36–62 days. The period of vigorous fermentation coincides with the period of initial fermentation and ends in 9–10 days, with accumulation of 12–14% of ethanol by volume. Unfortified wine materials obtained from black elderberries contain 22–38.3 mg/100 g of ascorbic acid (its content in wine materials is by 7.8–49.55% lower than in fresh berries) and 1750–3510 mg/100 g of phenolic substances (which is lower by 9.7–39.6%, as compared with fresh elderberries). The active acidity of black elderberry wine materials is 3.90–4.09 pH units, depending on the yeast race. A similar difference has been found for the redox potential (160–176 mV), which indicates that the wine materials from black elderberries are low-oxidised. The intensity of colour of the wine materials obtained from black elderberries (D420 + D520) varied from 3.08 to 3.20, and the colour shade from 0.88 to 0.92, which is typical of young red wines. These wine materials can be used to increase the quality and biological value of blended wines.

QTL mapping for bioenergy traits in sweet sorghum recombinant inbred lines

During the past decade, sweet sorghum (Sorghum bicolor Moench L.) has shown great potential for bioenergy production, especially biofuels. In this study, 223 recombinant inbred lines (RILs) derived from a cross between two sweet sorghum lines (Brandes × Wray) were evaluated in three trials. Single-nucleotide polymorphisms (SNPs) derived from genotyping by sequencing of 272 RILs were used to build a high-density genetic map comprising 3,767 SNPs spanning 1,368.83 cM. Multitrait multiple interval mapping (MT-MIM) was carried out to map quantitative trait loci (QTL) for eight bioenergy traits. A total of 33 QTLs were identified for flowering time, plant height, total soluble solids and sucrose (five QTLs each), fibers (four QTLs), and fresh biomass yield, juice extraction yield, and reducing sugars (three QTLs each). QTL hotspots were found on chromosomes 1, 3, 6, 9, and 10, in addition to other QTLs detected on chromosomes 4 and 8. We observed that 14 out of the 33 mapped QTLs were found in all three trials. Upon further development and validation in other crosses, the results provided by the present study have a great potential to be used in marker-assisted selection in sorghum breeding programs for biofuel production.
