Microgreens are emerging specialty food products which are gaining popularity and increased attention nowadays. They are young and tender cotyledonary leafy greens that are found in a pleasing palette of colors, textures, and flavors. Microgreens are a new class of edible vegetables harvested when first leaves have fully expanded and before true leaves have emerged. They are gaining popularity as a new culinary ingredient. They are used to enhance salads or as edible garnishes to embellish a wide variety of other dishes. Common microgreens are grown mainly from mustard, cabbage, radish, buckwheat, lettuce, spinach, etc. The consumption of microgreens has nowadays increased due to higher concentrations of bioactive components such as vitamins, minerals, and antioxidants than mature greens, which are important for human health. However, they typically have a short shelf life due to rapid product deterioration. This review aimed to evaluate the postharvest quality, potential bioactive compounds, and shelf life of microgreens for proper management of this specialty produce.

Formulation of gluten free crackers based on brown rice flour from two varieties and apple pomace was studied during the present investigation. Pomace flour blends were prepared by incorporating 0%, 3%, 6% and 9% apple pomace in brown rice flour. Viscosity profile showed decrease in pasting properties except pasting temperature which increased with increase in pomace level. The hunter colour value (L * ) and fracture force of crackers are decreased with increase in pomace level. The crackers were investigated and compared for composition, antioxidant properties (DPPH, total phenolic content, total flavonoid content, reducing power), minerals and sensory properties. The increased amount of apple pomace in the flour formulation resulted in higher antioxidant properties, total dietary fibre and minerals in the final product. Based on the present study, pomace based rice crackers have good potential for consumer and regarded as health promoting functional food, especially for coeliac disease patients. ª 2015 The Authors.
