Application of Enoki Mushroom (Flammulina Velutipes) Stem Wastes as Functional Ingredients in Goat Meat Nuggets.

ABSTRACT: The impact of different amounts (2%, 4% and 6%) of enoki (Flammulina velutipes) mushroom stem waste (MSW) powder on the physicochemical quality, color and textural, oxidative stability, sensory attributes and shelf-life of goat meat nuggets was evaluated. These mushroom by-products (MSW powder) contained a good source of protein (13.5%), ash (8.2%), total phenolics content (6.3 mg GAE/g), and dietary fiber (32.3%) and also exhibited the potential to be strong antioxidants, due to their good metal chelating ability (41.3%), reducing power (60.1%), and free radical scavenging activity (84.2%). Mushroom stem waste improved (p < 0.05) the emulsion stability, dietary fiber, ash and phenolics content of nuggets compared to control. Although no significant differences (p > 0.05) in expressible water and textural properties were observed among the formulations, but MSW powder improved the water holding capacity and slightly decreased the hardness. Further, the inclusion of MSW significantly (p < 0.05) improved the oxidative stability and shelf-life of treated nuggets by reducing lipid oxidation during the nine-day storage period. Again, the inclusion of MSW did not negatively affect the color and sensory attributes of treated meat nuggets. Overall, our results suggest that enoki mushroom stem waste (4%) can be used as a value-added functional ingredient to produce nutritionally improved and healthier meat products.

Project description:Most of the edible mushrooms cannot be cultivated or have low yield under industrial conditions, partially due to the lack of knowledge on how basidioma (fruiting body) development is regulated. From winter mushroom (Flammulina velutipes), one of the most popular industrially cultivated mushrooms, a transcription factor, PDD1, with a high-mobility group (HMG)-box domain was identified based on its increased transcription during basidioma development. pdd1 knockdown by RNA interference affected vegetative growth and dramatically impaired basidioma development. A strain with an 89.9% reduction in the level of pdd1 transcription failed to produce primordia, while overexpression of pdd1 promoted basidioma development. When the transcriptional level of pdd1 was increased to 5 times the base level, the mushroom cultivation time was shortened by 9.8% and the yield was increased by at least 33%. RNA sequencing (RNA-seq) analysis revealed that pdd1 knockdown downregulated 331 genes and upregulated 463 genes. PDD1 positively regulated several genes related to fruiting, including 6 pheromone receptor-encoding genes, 3 jacalin-related lectin-encoding genes, FVFD16, and 2 FVFD16 homolog-encoding genes. PDD1 is a novel transcription factor with regulatory function in basidioma development found in industrially cultivated mushrooms. Since its orthologs are widely present in fungal species of the Basidiomycota phylum, PDD1 might have important application prospects in mushroom breeding.IMPORTANCE Mushrooms are sources of food and medicine and provide abundant nutrients and bioactive compounds. However, most of the edible mushrooms cannot be cultivated commercially due to the limited understanding of basidioma development. From winter mushroom (Flammulina velutipes; also known as Enokitake), one of the most commonly cultivated mushrooms, we identified a novel transcription factor, PDD1, positively regulating basidioma development. PDD1 increases expression during basidioma development. Artificially increasing its expression promoted basidioma formation and dramatically increased mushroom yield, while reducing its expression dramatically impaired its development. In its PDD1 overexpression mutants, mushroom number, height, yield, and biological efficiency were significantly increased. PDD1 regulates the expression of some genes that are important in or related to basidioma development. PDD1 is the first identified transcription factor with defined functions in mushroom development among commercially cultivated mushroom species, and it might be useful in mushroom breeding.
