“…Despite being rich in sugars and minerals and forming a large part of the fruit waste, kinnow pulp does not find any significant commercial application in India and is disposed of into the municipal bins for rotting thus leading to environmental pollution. Although citrus peel has been exploited for production of ethanol, pectin, alkaloids and carotenoids (Grohmann et al 1995;Wilkins et al 2007;Xu et al 2008;Aravantinos-Zafiris et al 1992), the use of citrus pulp for any industrial application could not be found in any report or literature. Since the price of oil is rising rapidly and some of the food crops are being used to produce biomass energy sources resulting in shortage of food supply, utilisation of cellulosic biomass appears to be an attractive proposition.…”

A study was conducted to appraise the potential of using kinnow pulp for production of cellulases by Trichoderma reesei Rut C-30. Out of the different combinations tried out, dried kinnow pulp supplemented with wheat bran in the ratio of 4:1 resulted in the highest filter paper cellulase (FPase) activity of 13.4 IU/gds whereas endo-1,4-β-glucanase (CMCase) activity was found to be best when kinnow pulp was supplemented with wheat bran in the ratio 3:2 using Mandel Weber (MW) medium. β-glucosidase activity of 18 IU/gds was again found to be maximum in treatment involving 3:2 ratio of kinnow pulp to wheat bran in MW medium. However, supplementing kinnow pulp with wheat bran in 3:2 using water as medium resulted in an FPase:β-glucosidase ratio of nearly 1:1 which is considered to be most appropriate for achieving ideal saccharification efficiency in case of pretreated lignocellulosic material. Thus, this study involved the utilisation of kinnow pulp for production of cellulases and demonstrated that a substrate which does not find any commercial significance and causes environmental pollution due to its poor disposal holds promise as a substrate for production of cellulases.

“…The side streams generated are mostly composed of water and hydrocarbons (80-90%) with a low percentage of fat and proteins (Mirabella et al, 2014;Mullen et al, 2015). Orange peel is a rich source of essential oils (limonene), carotenoids, phenolic antioxidants, and pectin (Aravantinos-Zafiris et al, 1992;Chedea et al, 2010;Espina et al, 2011;May, 1990). A broad range of food products can be derived from this fruit namely sweet orange oil, orange blossom, honey, or marmalade (Siles López et al, 2010).…”

Food side streams contain useful compounds such as proteins, sugars, polyphenols, and amino acids that might get discarded during processing. The concentration of these components may be low (e.g., fruit side streams are mainly composed by water, around 90%, while polyphenol content in rapeseed meal is less than 3% dry weight) and therefore effective separation techniques should be evaluated. The aim of this review is to identify the different process steps (like pretreatment, volume reduction, phase change, solid removal, purification, and formulation) required to recover high-value products from agri-food residues. It reviews different plant-based byproducts as sources (cereal bran, fruit pomace, oilseed meals, fruit wastewater) of valuable compounds and discusses the relevant technologies required for processing (such as extraction, adsorption, crystallization, drying, among others). A structured approach to design recovery processes presented focused on high purity products. This work demonstrates that multiple high-value products can be recovered from a single agri-food side stream depending on the processing steps and the origin source (strong and soft structures and wastewater).

“…Carotenoids have been extracted using organic solvents (Aravantinos-Zafiris, Oreopoulou, Tzia, & Thomopoulos, 1992;O'Day and Rosenau, 1982) but the heightened public awareness of health issues and the application of more restrictive regulations have stimulated the technological development of supercritical fluids and brought about an increase in interest in the recovery of natural products using supercritical carbon dioxide. Mendes et al (1995), Careri et al (2001) and Macías-Sánchez et al (2005, 2007) have all successfully used supercritical carbon dioxide (scCO 2 ) to obtain carotenoid extracts from the microalgae Chlorella vulgaris, Spirulina platenses, Nannochloropsis gaditana, Synechococcus sp.…”
