Guava (Psidium guajava L.) seed: A low-volume, high-value byproduct for human health and the food industry.

Guava processing industries generate peel and seeds as primary waste fractions. Guava seeds obtained after fruit processing possess untapped potential in the field of food science due to the presence of a diversity of nutritional and bioactive compounds. Along with offering a detailed understanding of the nutritional attributes of guava seeds, the present review comprehensively elaborates on the therapeutic activities of their bioactive compounds, their techno-functional properties, and their other edible and nonedible applications.

Onion (Allium cepa L.) peels: A review on bioactive compounds and biomedical activities.

Huge quantities of byproducts/wastes generated in onion processing are usually discarded, but they are excellent sources of bioactive compounds and phytochemicals. However, with growing interest in the sustainable use of resources and the circular economy to reduce adverse impacts on the environment, food processing wastes such as onion peel/skin can be extracted and employed as inputs in developing or reformulating nutrient supplements, and pharmacological drugs. This review highlights major bioactive components, especially total phenolics, total flavonoid, quercetin and its derivatives present in onion peel/skin and their therapeutic applications as cardioprotective, neuroprotective, antiobesity, antidiabetic, anticancer and antimicrobial agents.

Bio-scouring of Non-spinnable Cotton by a Crude Enzyme of a New Fungal Strain sp. VM-1, Isolated from Banana Pseudostem Waste.

Unlabelled: In the present study, we isolated and identified a new fungus, sp VM-1 from banana pseudostem waste. The fungal strain, sp. VM-1 was grown on a substrate (banana pseudostem, cottonseed hulls and cottonseed meal in the ratio of 60:30:10, respectively) for 7 days and the crude enzyme was extracted from the fermented substrate.

Delineating the inherent functional descriptors and biofunctionalities of pectic polysaccharides.

Pectin is a plant-based heteropolysaccharide macromolecule predominantly found in the cell wall of plants. Pectin is commercially extracted from apple pomace, citrus peels and sugar beet pulp and is widely used in the food industry as a stabilizer, emulsifier, encapsulant, and gelling agent. This review highlights various parameters considered important for describing the inherent properties and biofunctionalities of pectins in food systems.

Custard Apple ( L.) Leaves: Nutritional Composition, Phytochemical Profile, and Health-Promoting Biological Activities.

L. (custard apple) belongs to the family Annonaceae and is an important tropical fruit cultivated in the West Indies, South and Central America, Ecuador, Peru, Brazil, India, Mexico, the Bahamas, Bermuda, and Egypt. Leaves of custard apple plants have been studied for their health benefits, which are attributed to a considerable diversity of phytochemicals.

Guava ( L.) Leaves: Nutritional Composition, Phytochemical Profile, and Health-Promoting Bioactivities.

(L.) belongs to the Myrtaceae family and it is an important fruit in tropical areas like India, Indonesia, Pakistan, Bangladesh, and South America. The leaves of the guava plant have been studied for their health benefits which are attributed to their plethora of phytochemicals, such as quercetin, avicularin, apigenin, guaijaverin, kaempferol, hyperin, myricetin, gallic acid, catechin, epicatechin, chlorogenic acid, epigallocatechin gallate, and caffeic acid.
