“…Among these species, L. mutabilis Sweet has aroused special interest in the research area due to its high nutritional value, registering a higher value of protein (41–51%) and fat (14–24%) compared with other lupine species (Jacobsen & Mujica, 2006). Moreover, L. mutabilis seeds are a rich source of other nutritional components as minerals, with a high content of calcium, phosphorus, potassium, and iron (Chirinos‐Arias, 2015); vitamins, being a good source of B group, particularly niacin (Trugo, Baer, & Baer, 2003); and phytochemical compounds that give it an antioxidant capacity as tannins and flavonoids, being the only one with isoflavones content among the species of the genus Lupinus (Chirinos‐Arias, 2015).…”

The purpose of this study was to evaluate the use of supercritical fluid extraction with cosolvent (SFE-co) as an alternative process in the extraction of lupin alkaloids. A sample of crushed Lupinus mutabilis Sweet seeds, with a high content of alkaloids, was treated using aqueous extraction (AQE) and SFE-co, where the effect of the operating conditions and the solvent in the SFE-co were evaluated applying a factorial design. Results showed that both methods reduced the content of total alkaloids in the lupin seed, ensuring its safe consumption. SFE-co got an extraction yield (39.19 ± 0.14 mg/g) comparable with AQE (39.22 ± 0.16 mg/g) at a temperature of 323 K, a pressure of 27 MPa, using as a solvent supercritical carbon dioxide (scCO 2) and dilute ethanol solution, but limited to a fraction of the treated sample. SFE-co, unlike AQE, was able to keep the nutritional value of the lupin seeds, reducing the time process from 235 hr (AQE) to 2.5 hr, assuring the non-use of an excessive amount of water and hazardous solvents. Moreover, the fractions formed in the extraction vessel by SFE-co allowed the understanding of the extraction mechanism of different components from a complex matrix related to their chemical polarity. Practical Applications This study shows that it is possible to remove lupin alkaloids with green technology as supercritical fluid extraction with cosolvents, reaching extraction yields comparable with the conventional method (aqueous extraction), keeping the nutritional value of the sample, saving time and resources. However, working with a larger quantity of material than the usual used in a laboratory showed an inhomogeneous extraction of alkaloids from the sample, limiting the optimal extraction yield to one of the fractions formed. This reveals a future problem in the use of this technology at an industrial level, where the characteristics of the extracts are not only important but also the material treated since, in the lupin industry, the debittered seed and the released alkaloids are useful in the food and pharmaceutical industries, respectively. 1 | INTRODUCTION Lupins are legumes whose cultivation has grown around the world, being the Lupinus albus, Lupinus luteus, Lupinus angustifoilius, and Lupinus mutabilis, the major species cultivated (Carvajal-Larenas, Linnemann, Nout, Koziol, & van Boekel, 2016). Among these species, L. mutabilis Sweet has aroused special interest in the research area due to its high nutritional value, registering a higher value of protein

“…The dietary fibre in the kernels is in the form of thickened walls of the mesophyll cells [ 17 , 18 ], which mainly consist of non-starch polysaccharides and raffinose family oligosaccharides such as raffinose, stachyose, and verbascose [ 19 , 20 ]. More specifically, it is composed of the monosaccharides galactose (67.6%), arabinose (11.5%), uronic acids (8.1%), glucose (7.6%), and xylose (2.6%) [ 15 ].…”

The kernels (dehulled seeds) of lupins (Lupinus spp.) contain far higher dietary fibre levels than other legumes. This fibre is a complex mixture of non-starch polysaccharides making up the thickened cell walls of the kernel. The fibre has properties of both insoluble and soluble fibres. It is a major by-product of the manufacture of lupin protein isolates, which can be dried to produce a purified fibre food ingredient. Such an ingredient possesses a neutral odour and flavour, a smooth texture, and high water-binding and oil-binding properties. These properties allow its incorporation into foods with minimum reduction in their acceptability. The lupin kernel fibre (LKF) has demonstrated beneficial effects in clinical studies on biomarkers for metabolic diseases such as obesity, type 2 diabetes, and cardiovascular disease. It can be described as a “prebiotic fibre” since it improves gut micro-floral balance and the chemical environment within the colon. Thus, LKF is a health-functional ingredient with great opportunity for more widespread use in foods; however, it is evident that more non-thermal methods for the manufacture of lupin kernel fibre should be explored, including their effects on the physicochemical properties of the fibre and the effect on health outcomes in long term clinical trials.

The popularity of natural dyes is increasing day by day due to their properties such as soothing colors, non carcinogenic, non hazardous and safe for environment. Some natural dyes also have been reported antibacterial properties. In present research work owers of Butea monosperma and Tagetes erecta were used for dye extraction. Banana pseudostem sap and Punica granatum rind taken as biomordant. High performance thin layer chromatography was conducted for identi cation of components of Butea monosperma, Tagetes erecta, Banana (Musa sp.) pseudostem sap and Punica granatum rind. Dyeing of two types of cotton fabrics performed at pre-optimized conditions. The antibacterial activity of dyed fabrics was evaluated quantitatively and qualitatively. Research nding supported the usage of Butea monosperma, Tagetes erecta, Banana (Musa sp.) pseudostem sap and Punica granatum rind in textile dyeing process. IntroductionNatural dyes are one of the most important natural products obtained from plants, animals, minerals, and micro-organisms. These dyes are used to color fabric, food, cosmetic products, and in decorative arts from the ancient period. After 1856 with the discovery of synthetic dyes, the popularity of natural dyes has diminished. Textile industries attracted to synthetic dyes which are cost-effective, fast in color and easy to apply on textiles. Wide application of synthetic dyes for long time resulted carcinogenic effects, mutagenic and non-biodegradable nature (Kiumarsi et al. 2017). Now a days awareness spreads for zero discharge emission, global warming, and ecosystem health for which green products are again in demand (Sagnella et al. 2014; Sangella et al. 2015). In this concern, people are also taking interest in hygiene and safe clothing. Cotton is one of the most common fabrics for apparels in all over the world.Cotton is produced naturally and a good substrate to grow on microorganism (Fu et al. 2011;Zhou and Kan 2015). As a hydrophilic nature, cotton easily provides suitable conditions, such as humidity, adequate temperature, and nutrition, for the growth of microorganisms, which generates an unpleasant odor, stains, and discoloration of the fabric. Therefore, it becomes necessary to apply an antibacterial nishing on cotton fabrics. The e ciency of any agent or substance which is used to mainly against bacteria for killing or inhibition is called antibacterial properties. Antibacterial nishes generally applied by using spun in additives, Padding, Spraying, Microencapsulation, Polymer modi cation etc. Many natural dyes have resistance towards bacterial colonies growth. Therefore, in this research work dyeing of cotton fabric is done with natural dyes and mordants to explore safe and hygienic clothing.Flowers of Butea monosperma and Marigold were taken as a dye source. However, Pomegranate rind and Banana pseudostem sap is taken as mordant. Most of the natural dyes have very low a nity towards fabric, so a mordant ( xing agent) required to x dyes on fabric. Chromium, copper, iron, tin and tannic acid etc. ...
