Retail lighting and packaging influence consumer acceptance of fluid milk

摘要: Abstract Little is known about the effect of retail light-emitting diode (LED) exposure on consumer acceptance milk. The study objective was to determine effects fluorescent and LED lighting under storage conditions Consumer milk stored determined through sensory evaluation (2 studies; n=150+ each) analytical measures (dissolved oxygen, secondary oxidation products, riboflavin retention). Study 1 evaluated in high-density polyethylene (HDPE) packages for 4h light (960 lx). Commercially available HDPE package treatments included translucent (most commonly used), white [low concentration (1.3%) TiO 2 ], yellow HDPE; addition, with a higher (high white; 4.9% ) foil-wrapped (control) were tested. Translucent control also tested light. terephthalate (PET) (1,460 PET packaging (medium, 4.0% ; high, 6.6% as well (exposed fluorescent), clear (fluorescent LED), light-protected control. Overall mean acceptability ranged from "like slightly" moderately" significantly lower exposed Milk had comparable overall scores when Only condition (both HDPE) diminished acceptability. Fluorescent negatively influenced flavor significant penalty (2.0–2.5 integers) PET. aftertaste packaged HDPE. Changes dissolved oxygen content, an indication oxidation, supported observed differences Consumers like fresh milk, which can be protected by selecting appropriate that blocks detrimental wavelengths.
