Mushroom: an emerging source for next generation meat analogues

mycolabadmin

Mushrooms are emerging as excellent meat substitutes because they have a meaty, chewy texture and savory flavor similar to meat, while being nutritious, low in fat, and sustainable to grow. When added to meat products like sausages, burgers, and nuggets, mushrooms improve texture, extend shelf-life, and reduce spoilage. The growing shift toward plant-based eating combined with environmental concerns makes mushroom-based meat alternatives an attractive option for consumers seeking healthier and more sustainable food choices.

Effect of Dietary Insect Meal and Grape Marc Inclusion on Flavor Volatile Compounds and Shell Color of Juvenile Abalone Haliotis iris

mycolabadmin

Researchers tested whether using insect meal and grape marc as sustainable alternatives to fish meal in abalone feed would affect meat flavor and shell color. The study found that grape marc reduced unpleasant off-flavors in the meat while insect meal had minimal effect on flavor. Neither ingredient significantly changed shell color. These findings suggest these sustainable ingredients could improve both environmental impact and product quality in abalone farming.

Mechanistic insights into volatile odor changes in surimi gels with typical cross-linking degrees during frozen storage based on lipidomics analysis

mycolabadmin

When surimi (a fish-based food product) is frozen for long periods, its pleasant fish aroma fades while unpleasant fishy and oily smells develop. This study found that this change happens because fats in the surimi oxidize and break down during freezing. Using faster freezing methods and chemically strengthening the surimi’s structure can help preserve the original flavor. The research identified specific fats that are responsible for creating unwanted odors, providing guidance for better preservation techniques.

Comparative Characterization of Key Volatile Compounds in Slow- and Fast-Growing Duck Raw Meat Based on Widely Targeted Metabolomics

mycolabadmin

This study compared the aroma and flavor compounds in raw duck meat from two different breeding types: slower-growing heritage breeds and faster-growing commercial breeds. Using advanced chemical analysis tools, researchers found that slow-growing ducks produce meat with a fatty and fruity smell due to higher levels of certain oils, while fast-growing ducks have a mushroom-like aroma. The study also revealed that differences in the meat’s chemical composition, particularly in fat metabolism and amino acids, explain these flavor differences and can help duck farmers breed better-tasting birds.

Effect of Flammulina velutipes polysaccharides on the physicochemical properties of catfish surimi and myofibrillar protein oxidation during frozen storage

mycolabadmin

Researchers discovered that mushroom polysaccharides extracted from Flammulina velutipes roots can protect fish surimi (a protein product used in food manufacturing) during frozen storage. When added to surimi at 2% concentration, these natural mushroom extracts prevented protein damage and maintained product quality just as well as traditional chemical preservatives, but without the added sweetness or calories. This finding suggests that mushroom-based compounds could offer a healthier alternative for preserving frozen food products.

Physicochemical Properties and Volatile Profile of Chito: A Traditional Dry-Cured Goat Meat Product

mycolabadmin

Chito is a traditional Mexican goat meat product that comes in two forms: one for immediate eating and one pressed for sale in other regions. Researchers studied these products over three years and found that the pressed version becomes harder, saltier, and develops more of the rancid flavors associated with fat breakdown. Despite these differences, both versions maintain safe bacteria levels through the natural preservation from salt and sun-drying.

Influences of Spices on the Flavor of Meat Analogs and Their Potential Pathways

mycolabadmin

This research studied how adding spices like black pepper, garlic, onion, and red pepper to plant-based meat products during manufacturing can improve their flavor. Scientists analyzed over 50 commercial meat analog products and found that spices reduced unpleasant bean-like flavors while adding pleasant tastes. When spices were added during the high-temperature extrusion process used to make these products, they prevented bad-tasting chemicals from forming and added nice flavors like citrus and spice notes.
