nx_icecream_bench.nx -- THE RULER. Score a frozen dessert against Ben & Jerry's Vanilla, the declared SOTA reference for this lane. ===== WHY A RULER COMES FIRST ==================================== "Exceed Ben & Jerry's" is not a formulation instruction until something can SCORE both products on the same axes. This organ is that scorer. It holds no ambition and proposes no recipe: it computes what a label implies, what the law actually permits, and where the reference product is structurally weak. The formulator is a separate organ and must be argued WITH this one, never instead of it. ===== THE REFERENCE, FROM THE ACTUAL LABEL ======================= Ben & Jerry's Vanilla, US pint, UPC 076840400058. Ingredient declaration in order: Cream, Skim Milk, Liquid Sugar (Sugar, Water), Water, Egg Yolks, Sugar, Guar Gum, Vanilla Extract, Vanilla Beans, Carrageenan. Nutrition panel, 2/3 cup (143 g) serving: 330 kcal, 21 g fat (14 g sat), 29 g carbohydrate (28 g sugars), 6 g protein, 95 mg cholesterol. Pint = 16 fl oz = 473 mL, 3 servings => 429 g net. The net weight is DERIVED (US frozen dessert is sold by volume; weight is not declared), and bench_net_weight_is_derived says so. **TWO FACTS IN THAT DECLARATION DECIDE THE WHOLE COMPETITIVE PICTURE:** 1. The only hydrocolloids are GUAR (primary) and CARRAGEENAN (secondary). There is no locust bean gum -- which matters because this lane's own gap ledger had named LBG as "how industry slows recrystallisation". The actual competitor does not use it. 2. There is NO ADDED EMULSIFIER. Egg yolk is the entire emulsifier system -- no mono- and diglycerides, no polysorbate 80. That is the exploitable weakness, and it is the reason this organ models meltdown. ===== THE LEGAL FINDING THIS ORGAN CARRIES ======================= 21 CFR 135.110 imposes FOUR floors on anything labelled "ice cream": >=10% milkfat, >=20% total milk solids, >=4.5 lb/gal finished weight, and >=1.6 lb TOTAL FOOD SOLIDS per gallon. nx_icecream enforces the first three. It declares IC_FDA_MIN_FOOD_SOLIDS_Q2 = 160 for the fourth and then never reads it -- a dead constant, so the fourth floor is documented
