The objective of this work was to determine the effect of the reduction and substitution of salt (NaCl) in pacu (Piaractus brachypomus) burgers, an Amazonian freshwater fish. In the first stage, five treatments with NaCl concentrations from 0.5 to 1.5 g/100 g were evaluated for proximal composition, instrumental texture, cooking losses, sensory profile, overall liking, and lipid oxidation for eight weeks. The results suggest a 50% reduction in NaCl content without affecting the parameters of burgers. In the second stage, NaCl was replaced up to 50% by potassium chloride (KCl) or calcium chloride (CaCl2), observing that CaCl2 at 50% substitution of NaCl presents better compatibility with the product in the chemical aspect, instrumental texture, sensory profile and overall liking, with the improvement in the decrease of the lipid oxidation compared to the product with only NaCl. The NaCl r...

This study aimed to formulate burgers made from three Amazonian fish species: pacu (Pyaractus brachypomus), boquichico (Prochilodus nigricans), and bujurqui (Chaetobranchus flavescens), focusing on sodium reduction and fortification with fish oil microparticles (FOM) rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The proximal composition, sodium and calcium content, instrumental texture profile, fatty acid profile, sensory profile, and overall liking were evaluated. Differences in proximal composition and fatty acid profiles between the fillets were reflected in the burgers. Fortification with FOM increased EPA and DHA in the burgers; thus, they can be considered “high in omega-3 fatty acids” and reduced the n-6/n-3 ratio below 4. There were sensory attributes that could be related to lipid oxidation but reduced overall liking for less than 10% of consumers. Neve...

The association of processed food consumption with health problems has sparked interest among consumers and the food industry in the production of healthier and more sustainable foods. Processed meats, which are made from the skeletal muscle of edible animal species, have unfavorable characteristics due to the incorporation of ingredients and synthetic additives associated with the occurrence of diseases and allergies. In this context, this review presents the pijuayo as a healthy and sustainable alternative in the formulation of meat and fish products. The nutritional benefits of this Amazonian resource are described, as well as its uses reported in the literature. The pulp, peel, stem, and oil extracts of pijuayo have been used to replace animal fat and to act as extenders and colorants in processed meats. The benefits include the enhance of sensory characteristics and acceptability re...

This study aimed to evaluate the incorporation of peach palm (PP) pulp and peel flours as substitutes for animal fat (25 and 50% substitution) in beef-based burgers. Incorporation of PP flours reduced hardness, springiness, cohesiveness, chewiness, fat, cooking losses, and diameter reduction. Burgers made with PP peel flour stood out for having low values of lipid oxidation in the two levels of fat substitution (0.14–0.23 malondialdehyde/kg) (p < 0.05). PP fruit has the potential to be utilized as a new ingredient in burgers, but future studies are needed regarding detailed sensory trials and consumer acceptance.

Frutos de ají charapita(Capsicum frutescens) fueron secados en lecho fluidizado, en bandejas y por liofilización. Tamaño de la muestra de ají (pequeño y grande) y temperatura de secado (50°C, 60°C y 70°C) fueron variables de estudio para el secado en lecho fluidizado y en bandejas, en cuanto que en el liofilizadose usaron mezclas de ají fresco licuado en agua, con diluciones de 1:0.25; 1:0.50 y1:0.75 (ají: agua). Las muestras secadas en lecho fluidizado y en bandejas, obtuvieron menores tiempos de procesamiento cuando comparadas con el secado por liofilización. Las muestras de tamaño grande secadas a 70°C en lecho fluidizado y en bandejas presentaron valores dehumedad de 5.36%y 7.11% respectivamente, y la muestra liofilizada obtuvo 7.75% de humedad. En el análisis microbiológico Salmonella sp., mohos y levaduras se encuentran dentro los límites de la normatividad sanitari...

The study aimed to evaluate the combined use of ultrasound (US) and incorporation of micronized salt (MS) as a strategy for reducing sodium without affecting the quality of beef burgers. Ten treatments were manufactured with varying MS content (0.75 %, 1.0 %, and 1.5 %) and ultrasound time (0, 5, and 10 min), with a control treatment manufactured at 1.5 % of regular salt without ultrasound. The beef burgers formulated with 0.75 % MS submitted to the US for 10 min (M0.75US10) reduced the salt content by 50 %, thereby efficiently maintaining texture profile (hardness, springiness, cohesiveness, and chewiness) and decreasing the cooking loss and diameter reduction compared to the control treatment. M0.75US10 treatment also preserved the color of samples after cooking, keeping myoglobin stable. Therefore, micronized salt coupled with ultrasound technology reduces sodium chloride content in b...
