Easily sourced mucus from various plant parts is an odorless, colorless and tasteless substance with emerging commercial potential in agriculture, food, cosmetics and pharmaceuticals due to its non-toxic and biodegradable properties. It has been found that plant-derived mucilage can be used as a natural thickener or emulsifier and an alternative to synthetic polymers and additives. Because it is an invisible barrier that separates the surface from the surrounding atmosphere, it is used as edible coatings to extend the shelf life of fresh vegetables and fruits as well as many food products. In addition to its functional properties, mucilage can also be used for the production of nanocarriers. In this review, we focus on mucus extraction methods and its use as a natural preservative for fresh produce. We detailed the key properties related to the extraction and preservation of food, the mechanism of the effect of mucus on the sensory properties of products, coating methods when using mucus and its recipe for preserving fruit and vegetables. Understanding the ecological, economic and scientific factors of production and the efficiency of mucus as a multi-directional agent will open up its practical application in many industries.

Cereal Chem. 94(3):437-442Solid-state fermentation (SSF) represents a technological alternative feature for a great variety of legumes and cereals to improve their functional and nutritional properties. Iron and zinc deficiencies are major health concerns as a public health problem. Therefore, the present investigation was carried out to assess the consequences of SSF on functional properties and in vitro bioavailability of minerals through Caco-2 cells. Fungal strain Aspergillus oryzae (generally recognized as safe) was used for SSF. The effect of SSF on the functional properties (bulk density, water-and oil-binding capacities, emulsion activity and stability, and foaming capacity and stability) of a black-eyed pea flour sample was evaluated. SSF significantly (P < 0.05) decreased the bulk density of black-eyed pea flour; however, significant (P < 0.05) improvement was observed in other functional properties. An unfermented flour sample showed significantly (P < 0.05) decreased iron and zinc bioavailability and digestibility compared with that of the SSF flour sample. SSF significantly increased iron and zinc transport and retention through Caco-2 cells. Significantly increased ferritin content was also observed in the fermented flour sample compared with that of unfermented flour samples. † Corresponding
