“…Very low concentrations of quinolizidine alkaloids were observed in all the varieties (3.0 mg 100g -1 ) compared to the control Multitalia (166.4 mg 100g -1 ). The Lupanine was the most represented alkaloid (1.5 mg 100g -1 , on average of the tested varieties), whereas, Iso-lupanine was the least represented alkaloid (0.22 mg 100g -1 , on average of the tested varieties) (table 4); these results are in agreement with the observations of Muzquiz et al (1994) in the alkaloid profile of L. albus and with those of Boschin et al (2008) in nine alkaloid-poor varieties of L. albus and L. angustifolius grown in two climatically contrasting Italian sites. The chromatographic analysis allowed to identify the presence of Iso-lupanine only in L. albus; in L. angustifolius and L. luteus the Iso-lupanine content was below the instrumental limit of quantification (0.04 mg 100 g -1 ) (Tab.…”

The ban on animal protein supplements in animal nutrition and, particularly, the increase in the demand for alternative protein sources to replace soybean meal in organic farming has stimulated research on GM-free feeds and renewed interest in grain legumes. Of these lupin appears to be one of the more interesting and promising crops for ruminant diets, due to its key role in low-input cropping systems and its high protein content. The aim of this study was to evaluate the productive and nutritional characteristics of several sweet varieties of lupin seeds cultivated in the Mediterranean region. The trial was carried out during the years 2007/08 on a volcanic soil in East Sicily, employing 8 sweet cultivars belonging to Lupinus albus, L. angustifolius and L. luteus species. Yield and its components (pod plant -1 , seed pod -1 , 1000 seed weight) were evaluated. Crude protein, fibre fractions and alkaloid content were also determined. L. albus exhibited the highest yields (2.2 t ha -1 ), with an intermediate value of pod x plant (15.4). L. luteus yielded 1.5 t ha -1 and L. angustifolius 0.5 t ha -1 . L. luteus showed higher levels of crude protein (34.2%) although the greatest protein yield per hectare was recorded in L. albus (0.7 t ha -1 ). L. angustifolius showed the highest mean values of NDF (28.1%) and ADF (25%), whereas L. luteus the lowest mean values of ADL (1.75%). Six alkaloids were detected and quantified, among which, the Iso-lupanine always was the most abundant (1.5 mg 100g -1 , on average). Lower concentrations of quinolizidine were observed in L. luteus (0.9 -1.4 mg 100g -1 ) as compared with L. angustifolius (1.5 -5.5 mg 100g -1 ) and L. albus (3.8 -7.5 mg 100g -1 ). Alkaloid content was always lower than the safe limit of toxicity (< 0.20‰) indicated for human and animal consumption.

“…Total alkaloids were determined gravimetrically according to the methods described by Wysocka et al (1989). The dominant alkaloids in extracts obtained from defatted seeds of the particular varieties were identified by thin-layer chromatography according to Miizquiz et al (1994). Alkaloid extracts were separated on silica gel plates (Merck) using chloroform: cyclohexane:diethylamine (6:4:1) as the solvent system.…”

The size, weight and chemical composition of seeds, cotyledons and seed coat of three Polish varieties of low-alkaloid white lupin, Wat, Hetman and Bardo, were determined in seed samples from the 1992-1994 harvests. In the oldest variety, Wat, the average proportion of the seed coat was nearly 21%, while crude protein content in seeds amounted to 34% of DM. The newer varieties, Hetman and Bardo, had a lower seed coat content (about 18%) and contained more protein (37 and 38% DM, respectively). The alkaloid content in Wat seeds was almost 1 mg/g, while the newer varieties had half this amount. Large differences were found in the contents of nutrients and alkaloids, depending on harvest year. Dehulling raised the protein content to 41 -46% DM and significantly decreased the seed fibre content. Large variations in trace element content were found, independent of the lupin variety, most notably in respect to Mn, Fe and Cu. The Mn content of seeds was relatively high, ranging from 0.44 to 1.45 g/kg.

“…In their development, the alkaloid concentration in different plant parts (leaves, roots, stems) changes, reaching the highest value in the flowering stage. In Australian studies on white lupin the occurrence of 4 alkaloids was observed: albine (15%), 13-hydroxylupanine (8%), lupanine (70%), and multiflorine (3%) in the total amount not reaching over 0.01% (Petterson & Fairbrother 1996), while in Spanish studies additional a-isolupanine (Muzquiz et al 1994) as well as 13-α-angeloyloxylupanine and 13-tigloyloxylupanine were reported (Muzquiz et al 1998). Total alkaloid content in sweet white lupin cultivars has been significantly reduced in the process of domestication and breeding and does not currently exceed 0.02% (Prusinski 2015).…”

White lupin seeds have been used in human nutrition and treatment for several thousand years. Nowadays the use of white lupin seeds is limited by a small scale of their production. However, in the last 20 years quite new properties of white lupin have been discovered for the application in the production of different kinds of functional food. Unique traits of protein, fatty acids with a desirable ratio of omega-6 to omega-3 acids, and fibre as well as other specific components, for example oligosaccharides and antioxidants or non-starch carbohydrates, make white lupin an excellent component in many healthy diets. The effects of white lupin components concern the physiological condition of the human body, including diabetes, hypertension, obesity, cardiovascular diseases, lipid concentration, glycaemia, appetite, insulin resistance, and colorectal cancer. Seeds are used among others for the production of gluten-free flour, bacterial and fungal fermented products, noodle and pasta products, as substitutes of meat, egg protein and sausages, also are cooked, roasted and ground and mixed with cereal flour in the production of bread, crisps and pasta, crisps and dietary dishes.
