Food spoilage is a major issue for the food industry, leading to food waste, substantial economic losses for manufacturers and consumers, and a negative impact on brand names. Among causes, fungal contamination can be encountered at various stages of the food chain e. Fungal development leads to food sensory defects varying from visual deterioration to noticeable odor, flavor, or texture changes but can also have negative health impacts via mycotoxin production by some molds. In order to avoid microbial spoilage and thus extend product shelf life, different treatments—including fungicides and chemical preservatives—are used. In parallel, public authorities encourage the food industry to limit the use of these chemical compounds and develop natural methods for food preservation. In this context, microbial agents corresponding to bioprotective cultures, fermentates, culture-free supernatant or purified molecules, exhibiting antifungal activities represent a growing interest as an alternative to chemical preservation. This review presents the main fungal spoilers encountered in food products, the antifungal microorganisms tested for food bioprotection, and their mechanisms of action. A focus is made in particular on the recent in situ studies and the constraints associated with the use of antifungal microbial agents for food biopreservation. Today, food losses are a major concern worldwide especially with an ever-growing world population and the fact that approximately one-third of all food produced for human consumption is either lost or wasted [ 1 ]. Each year, an estimated 1. The reasons for this massive global food loss are diverse, but microbial spoilage, which affects organoleptic product quality aspect, texture, taste, and aroma, plays a major role.

Mushrooms are fungi, biologically distinct from plant- and animal-derived foods fruits, vegetables, grains, dairy, protein [meat, fish, poultry, legumes, nuts, and seeds] that comprise the US Department of Agriculture food patterns operationalized by consumer-focused MyPlate messages. Although mushrooms provide nutrients found in these food groups, they also have a unique nutrient profile. Mushrooms, the fruiting bodies of macroscopic filamentous fungi that grow above the ground, have been a part of the human diet and used as both food and medicine for centuries. Initially, mycology, the study of fungi, arose as a branch of botany because fungi were considered primitive plants. Fungi now are accepted as a separate kingdom based on cellular organization rather than on observable and other features. Major differences that distinguish fungi from both plants and animals include the following. Fungi, lacking chlorophyll, exist on decaying material in nature and on substrate of various compositions when commercially grown. In addition, fungi contain chitin, a polysaccharide derivative of glucose also found in the exoskeleton of crustaceans and insects, not cellulose found in plants, and contain the unique sterol, ergosterol, rather than cholesterol found in mammalian cells. Although more than varieties of mushrooms are edible, those most familiar to US consumers are of the Agaricus bisporus species: the white button mushroom the most commonly consumed mushroom in the world, crimini, and portabella. Seasonal species such as morels Morchella esculenta and chanterelles Cantharellus cibarius are gathered in the wild and sold at retail stores and farmers markets. The USDA National Nutrient Database for Standard Reference, Release 27 SR27, includes composition data on white, crimini, shiitake, enoki, maitake, oyster, portabella, morel and chanterelle mushrooms, and portabella mushrooms exposed to ultraviolet UV light that converts the naturally present ergosterol to ergocalciferol vitamin D 2.
