(2024) with CC-BY.
Synergistic effects of laccase and pectin on the color changes and functional properties of meat analogues containing beet red pigment Beet red, laccase, and sugar beet pectin - The combination of laccase and pectin beet red-containing plant-based patties resulted in a similar grilled beef patty color- Laccase and sugar beet pectin can be utilized to improve the browning system of meat analogues containing beet red Adapted from Sakai et al. (2022) with CC-BY.
Beetroot juices as colorant in plant-based minced meat analogues: Color, betalain composition, and antioxidant activity as affected by juice type Beetroot juices - Addition of cooked beet root juice in textured soy protein could mimic raw minced beef color- The combination of commercial beet juice and textured soy protein could resemble raw minced pork color Adapted from Fernández-López et al. (2023) with CC-BY-NC-ND.
Application of ohmic cooking to produce a soy protein-based meat analogue Ohmic cooking and beet red - Higher ohmic cooking temperature induces brighter internal coloration of meat analogue Jung et al. (2022)
Varying the amount of solid fat in animal fat mimetics for plant-based salami analogues influences texture, appearance, and sensory characteristics Plant-based fat from canola, sal, and beetroot powder - Addition of 25%–50% sal fat in meat analogue could mimic pork fat even after drying- Pasteurization induces a color change of the product from deep red to orange-red Dreher et al. (2021)
Physicochemical properties of novel non-meat sausages containing natural colorants and preservatives Lycopene, paprika oleoresin, and red yeast rice powder - Superior sensory acceptance was observed for non-meat sausages containing paprika oleoresin (3 g/kg), red yeast rice (0.1 g/kg), and lycopene (0.32 g/kg) Akramzadeh et al. (2018)
Development of plant-based burgers using gelled emulsions as fat source and beetroot juice as colorant: Effects on chemical, physicochemical, appearance, and sensory characteristics Beetroot juice - Plant-based burgers with fresh beet juice were more susceptible to color change during cooking compared to commercial beet juice Adapted from Botella-Martínez et al. (2022) with CC-BY-NC-ND.
Synergistic effect of lactoferrin and red yeast rice on the quality characteristics of novel plant-based meat analog patties Lactoferrin and red yeast rice powder - Raw treatment patties were lighter with moderate CIE b* compared to raw beef patties Adapted from Bakhsh et al. (2022) with CC-BY.
Applications of various natural pigments to a plant-based meat analogue Beet red, Monascus red, paprika oleoresin, sorghum, and cacao - The combination of cacao (1.1–1.3 mg/g) and red beet (0.4–1.5 mg/g) showed similar coloration to Hanwoo rib patty- Single colorant in meat analogue was insufficient in mimicking the control Adapted from Ryu et al. (2023) CC-BY-NC-ND.
Characterization of plant-based meat alternatives blended with anthocyanins, chlorophyll, and various edible natural pigments Paprika, Monascus, grape, cherry, red cabbage, and beet red - Plant-based meat analogues with natural pigments showed lower CIE a* compared to conventional meat- Inconsistencies in the color coordinates of the treatments may be due to differences in the color of natural pigments, concentration, and substitution of plant-based protein Adapted from Bakhsh et al. (2023) with CC-BY.
