Effects of ultrasound on the structure and physical properties of black bean protein isolates

Bacterial cellulose (BC) has been produced for a number of applications, mainly focused on the biomedical area. Although there is a variety of interesting applications of BC for food and food packaging, only a few have been explored to the moment, since the high cost of BC production is usually considered as a limiting factor. On the other hand, several cost-effective culture media have been proposed, contributing to reduce BC production costs. This article overviews the bioprocess conditions that affects BC production and the main possible applications of BC for food and food packaging purposes.

Bacterial Cellulose as a Raw Material for Food and Food Packaging Applications

Bacterial cellulose (BC) is ultrafine, nanofibrillar material with an exclusive combination of properties such as high crystallinity (84%–89%) and polymerization degree, high surface area (high aspect ratio of fibers with diameter 20–100 nm), high flexibility and tensile strength (Young modulus of 15–18 GPa), high water-holding capacity (over 100 times of its own weight), etc. Due to high purity, i.e., absence of lignin and hemicellulose, BC is considered as a non-cytotoxic, non-genotoxic and highly biocompatible material, attracting interest in diverse areas with hallmarks in medicine. The presented review summarizes the microbial aspects of BC production (bacterial strains, carbon sources and media) and versatile in situ and ex situ methods applied in BC modification, especially towards bionic design for applications in regenerative medicine, from wound healing and artificial skin, blood vessels, coverings in nerve surgery, dura mater prosthesis, arterial stent coating, cartilage and bone repair implants, etc. The paper concludes with challenges and perspectives in light of further translation in highly valuable medical products.

Sulforaphane, a type of isothiocyanate hydrolysed from glucosinolate, is a powerful anticancer compound naturally found in food especially in broccoli sprouts. Despite the function of sulforaphane has been extensively studied in recent years, little attention has been given to methods that can maximize the production of this compound in broccoli sprouts. The present study optimised the enzymolysis conditions for sulforaphane production in broccoli sprouts using response surface methodology. The maximum sulforaphane production (246.95 μg/g DW) was achieved using a solid–liquid ratio of 1:30, hydrolysis time of 1.5 h, ascorbic acid content of 3.95 mg/g DW sample, and temperature of 65 °C. The highest sulforaphane content in broccoli sprouts were 233.80 μg/g DW in 5-day-old sprouts and 1555.95 μg/g DW at day 4 of storage. The highest antioxidant activities were 37.22 U/min/g DW in 3-day-old sprouts and 35.08 U/min/g DW on 4th day of storage.
