Supercritical carbon dioxide extraction of oils from Andean lupin beans

Oil extraction from Andean lupin beans (Lupinus mutabilis SWEET) via supercritical carbon dioxide (scCO2) was studied on both lab scale and pilot scale. On the lab scale, the effect of pressure, solvent-to-feed ratio (S/F), sample particle size and temperature on oil yield were evaluated. The oil quality (fatty acid [FA] composition and tocopherol content) were investigated. Five-hour scCO2 extraction yielded about 86% oil of Soxhlet extraction (using hexane as solvent). The fraction of unsaturated FA rose with extraction pressure at specific time. High tocopherol contents were detected in oils extracted at low pressure. An increase in temperature was unfavorable to oil and tocopherol yield, thereby confirming the validity for preserving oil extract quality under a mild scCO2 extraction condition. Oil quality and yield did not have identical optimum settings, opening up possibilities for producing different qualities of oils. Pilot-scale extraction offered comparable oil yield to lab-scale extraction at similar S/F ratio. Economic evaluation showed that it is promising to implement industrial scale scCO2 process for lupin oil extraction. It was predicted that, at a specific industrial scale of extraction (2 × 1000 L, 550 bar, 40°C and S/F of 24), the manufacturing cost of oils got close to actual commercial production cost.

State and progress of Andean lupin cultivation in Europe

Lupinus mutabilis is an important source of protein in different Andean countries, and its use in diets, particularly those of less wealthy individuals, has been observed for thousands of years. There is an increasing demand for protein crops suitable for Europe and this species is a potential candidate. Assessment of Lupinus mutabilis genetic material in European conditions started more than 40 years ago, with the characterization of a vast number of accessions from the Andean region. In this review, abiotic and biotic constraints to L. mutabilis cultivation in European soil and climatic conditions are discussed, and cultivation management practices are suggested. The beneficial interaction of L. mutabilis with Bradyrhizobium strains in the soil and various pollinator species is also discussed, and the effect of abiotic stresses on these interactions is highlighted. Prospects of alternative uses of L. mutabilis biomass in Northern Europe and opportunities for breeding strategies are discussed. In conclusion, the different approach to crop modeling for Southern and Northern European climatic conditions is highlighted

Supercritical carbon dioxide extraction of oil from Andean lupin seeds

The Andean lupin (Lupinus mutabilis) is one of the lost crops of Incas and has been grown in South America and as a food crop for thousands of years. The seeds are the main source of commercial value regarding the high content of oil (about 20%), protein (about 43%) and carbohydrates (about 33%). A European Union H2020 project, LIBBIO, aims to develop and optimize the breeding and cropping of the Andean lupin in the Europe, and to process the lupin seeds for new and high-value products for consumers and for incorporation into otherproducts. This study works at optimizing the oil extraction from the lupin seeds using supercritical carbon dioxide (scCO2), which has been tested for lupin oil extraction and is advantageous over organic extractants due to the mild operating temperature, costeffectiveness, nontoxicity, and easy post-separation.In the study designed by response surface methodology, the operating pressure,temperature, scCO2 flowrate, and sample mesh size, were investigated on their effect on the oil extraction efficiency. The pressure, scCO2 flowrate and mesh size were found to affect the extraction efficiency significantly. The higher the pressure and the smaller the mesh, the more oil was extracted over a specific period. Optimally about 85% of the oil was extracted by scCO2 compared with conventional Soxhlet extraction using hexane as the extractant. Oleicacid (46%) and Linoleic acid (32%) are the two main fatty acids in the extracted oil. About 80% of the fatty acids are unsaturated. The stearic acid is one of the main saturated fatty acids, which has relatively positive effects on human health to others. The pressure was found to significantly affect the fractions of the saturated and unsaturated fatty acids. The content of tocopherols in the extracted oil ranged from 1 to 20 mg/100g oil, which is comparable withliterature value.

COTOPAXI, Andean Lupin European breeder success

Plant Breeders Rights were granted to Vandinter Semo BV on 29th December 2020 for the Andean Lupin variety COTOPAXI. COTOPAXI is result of cooperation between Vandinter Semo, Hanze University of Applied Sciences and the H2020 BBI-JU European research project LIBBIO. Andean Lupin (Lupinus mutabilis) has its origin in South America and is one of the four lupin species for human consumption. Andean Lupin is a sustainable alternative for soybean because of its comparable oil and protein content and its contribution to biodiversity and soil improvement. COTOPAXI is the first Andean Lupin variety in Europe that has been granted with Plant Breeder Rights. Andean lupin oil has excellent fatty acid composition and is therefore suited for food applications like margarines and mayonnaises and also for cosmetic applications, especially hair care products, lipsticks and nourishing anti-aging skin care products. Andean Lupin bean is also rich in proteins, oligosaccharides, alkaloids and bioactive components. Andean lupin proteins can be used as functional food ingredients and as animal feed. Oligosaccharides have functional food applications because of their fermentative (prebiotic) potential in the human large intestine. Alkaloids are of interest because of their medical potential as anti-cancer medicine and as biodegradable natural crop protection agents. Andean lupin bioactives are suited as ingredients in anti-aging cosmetics and in functional foods. Andean lupin contributes to the plant-based protein transition and to EU policy becoming more independent from foreign protein imports. Rob van Haren, Professor Transition Bioeconomy at Hanze University of Applied Sciences, says: “Andean Lupin is one of the “lost crops of the Incas” like quinoa and chia. Andean lupin grows in the same agro-ecozone as potato and has therefore a great areal potential. Andean lupin oil and protein contents are comparable with soybean and hence its business case has the same potential as well.” Rob van Haren together with other partners initiated in 2015 the H2020 research project LIBBIO for developing the Andean lupin supply chain and its biorefinery processing. This was made possible by an Andean lupin pre-breeding collection established by Kiemkracht, the innovation alliance from Product Board Arable Products and the Innovation Network of the Ministry of Agriculture. Bert-Jan van Dinter, director Vandinter Semo, says: “We have been active in plant breeding for more than a century, our company started in 1914. Our focus is to breed new varieties for soil improvement and soil health. We also breed for double-target crops for yield and soil improvement. We started our cooperation in 2008 first with Kiemkracht and later with Hanze UAS within the H2020 project LIBBIO. Obtaining Plant Breeder Rights in Europe within 5 years of research is unique. COTOPAXI is the first variety emerging from our new breeding program. In coming years we intend to breed for properties like sweetness (low alkaloids), earliness and crop yield”. The Andean lupin COTOPAXI contributes to farmer income, sustainable and circular agriculture, profitable processing and biorefinery and sustainable natural products for European consumers.
