“…Lupin varieties containing ≥10 mg/g DM alkaloid in seeds were identified as "bitter lupin" [46,47]. Keuth et al [48] reported the total quinolizidine alkaloid levels as 20-21 mg/g with respect to two bitter lupin seeds varieties; simultaneously, 0.152 mg/g was reported for alkaloid levels relative to a sweet lupin variety. The QA analysis showed that the total alkaloid levels of untreated white and blue lupin seeds were found to be >1.943 mg/g and 0.894 mg/g, respectively (Tables 3 and 4).…”

In the current era, it is important to consider economic and ecological sustainability issues while optimally meeting the nutrient needs of poultry. The use and research of alternative feedstuffs have gained importance due to these factors. The aim of this study is to reveal the raw lupin seeds’ nutrient ingredients as an alternative feedstuff and the effects of debittering methods. In the present study, two different treatments (germination for 2 days; heat treatment in an autoclave at 130 °C for 20 min) were applied to white and blue lupin seeds, and the differences in nutrient compositions between them and raw seeds were determined. When fatty acid compositions were analyzed, oleic, γ-linolenic, arachidic, behenic, erucic, and lignoceric acid values were found to be the highest in the raw, autoclaved, and germinated forms of white lupin (p < 0.01). The highest values of palmitic, stearic, and linoleic acids were observed in blue lupin (p < 0.01). While the value of total quinolizidine alkaloids (QA) in raw white lupin grains was higher than 1.943 mg/g, it was higher than 1.800 mg/g in autoclaved and germination-treated grains. Similarly, the total QA value of raw blue lupin grains was 0.894 mg/g, 0.609 ± 0.244 mg/g in germination-treated seeds, and 0.705 ± 0.282 mg/g in autoclave-treated seeds. As a result of these findings, it can be said that the methods applied for the removal of bitterness gave promising results. Furthermore, it would be rewarding to use these lupin varieties in in vitro and in vivo experiments to reveal the impacts and mechanisms of debittering methods on poultry.
