Preparation and Characterization of a Novel Artemisia Oil Packaging Film and Its Application in Mango Preservation

mycolabadmin

Researchers developed a new type of edible film made from soybean protein and gelatin infused with Artemisia oil to preserve mangoes longer after harvest. This natural, biodegradable packaging film helps prevent mango spoilage by blocking light, reducing water loss, and stopping fungal growth that causes rot. When used to wrap mangoes, the film significantly extended shelf life and maintained freshness better than unwrapped fruit, offering an environmentally friendly alternative to conventional plastic packaging.

Upregulation of ACC deaminase gene in Bacillus velezensis UTB96 improved yield and shelf Life of Agaricus bisporus

mycolabadmin

Researchers developed a way to improve button mushroom production using a beneficial bacterium treated with calcium chloride. This treatment boosts the bacteria’s ability to reduce ethylene, a natural plant hormone that causes mushrooms to age quickly. The treated mushrooms showed 23% higher yields and stayed fresh for at least three weeks in storage without browning, making them more appealing to consumers.

Upregulation of ACC deaminase gene in Bacillus velezensis UTB96 improved yield and shelf Life of Agaricus bisporus

mycolabadmin

Researchers discovered that adding a beneficial bacteria called Bacillus velezensis UTB96 to mushroom growing substrates significantly improves both the amount of mushrooms produced and how long they stay fresh. When this bacteria was grown in a medium containing calcium chloride, it produced more of an enzyme called ACC deaminase that breaks down ethylene, a gas that causes mushrooms to age and brown. Mushrooms treated with this specially-prepared bacteria stayed fresher for three weeks in the refrigerator with minimal browning, and overall mushroom yield increased by up to 23%.

Effect of Antibacterial Peptide Microsphere Coating on the Microbial and Physicochemical Characteristics of Tricholoma matsutake during Cold Storage

mycolabadmin

This research demonstrates that coating expensive wild matsutake mushrooms with special antimicrobial peptides wrapped in tiny polymer microspheres can keep them fresh for up to 20 days instead of just 1-3 days. The coating works by protecting mushrooms from water loss, microbial spoilage, and browning while preserving their texture and nutritional quality. This edible coating technology could help mushroom producers sell their products over longer distances and extend availability of these prized wild mushrooms.
