lupins
Lupins are Europe's rising protein legume — sweet cultivars bred low in alkaloids, high in protein, and still novel enough to need this page.
Also appears on labels as: lupin · lupine · sweet lupin · white lupin
What it is
Seeds of sweet lupin varieties, bred to strip the bitter alkaloids that made ornamental lupins mildly toxic. The result is a genuinely impressive legume: more protein than most beans, low starch, and an established place in European and Australian feed and food.
Why it's in pet food
High plant protein without the starch load — attractive to grain-free and weight-conscious formulation. 'Sweet lupin' on a label denotes the low-alkaloid cultivar; food-grade supply chains use exactly these, which is the safety sentence the novelty demands.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Neutral: not on the legume flag's roster, no other rule touches it. As with every novel ingredient, unfamiliarity is not a finding — lupin's feed-science file is decades deep abroad. The garden-lupin alkaloid story belongs to ornamental plants, not the cultivars in commerce.
