Special Issue Information

Dear Colleagues,

The search for sustainable industrial processes has guided the production of chemicals and fuels from a biomass-based economy. However, millions of tons of by-products from the food processing industry are currently generated worldwide, being disposed of in landfills, used in composting, or for animal feed. Additionally, it is essential to change the form of production, converting the linear economy into a sustainable circular bioeconomy. The philosophy of the dominant economic model of “take, make and dispose” must be urgently transformed into a sustainable mode. For this, the concept of upcycled foods, which is the use of food ingredients or processed food materials that would, otherwise, be discarded, must be properly understood. Applying the concepts of a circular economy and biorefinery is decisive for recovering high-value-added molecules, since the growing demand for processed foods increases the generation of residues or by-products from processed foods. For the most part, these biomasses are not fully exploited, with insufficient knowledge about their nutritional and economic values.

Normally, food processing by-products are disposed of in landfills, used as animal feed, burned, or used in steam production. Therefore, considering the possibility to improve the use of these by-products, new strategies have been developed for the recovery of relevant substances from these biomasses, such as bioactive compounds, polysaccharides, proteins, oils, and fibers, among others, which could be recovered for further use in the food industry.

We invite you to submit your latest research findings or review articles to this Special Issue, which will bring together the current research on food ingredients recovered from food wastes and by-products.

If you have any questions, please do not hesitate to contact us. We look forward to hearing from you.

Hypoglycemic Ability of Sericin-Derived Oligopeptides (SDOs) from Bombyx mori Yellow Silk Cocoons and Their Physiological Effects on Streptozotocin (STZ)-Induced Diabetic Rats
by Chainarong Tocharus and Manote Sutheerawattananonda

Abstract
Patients with diabetes require daily medication to maintain blood sugar levels. Nevertheless, the long-term use of antidiabetics can lose efficacy and cause degeneration in some patients.

Patients with diabetes require daily medication to maintain blood sugar levels. Nevertheless, the long-term use of antidiabetics can lose efficacy and cause degeneration in some patients. For long-term diabetes care, integrating natural dietary foods and medicine is being considered. This study investigated the impact of SDOs on blood sugar levels and their physiological effects on diabetic rats. We induced diabetes in male Wistar rats with STZ (50 mg/kg) and then administered an oral glucose tolerance test to determine the SDO dosage comparable to glibenclamide. The rats were divided into nine groups: normal, diabetic, and diabetic with insulin (10 U/kg), glibenclamide (0.6 mg/kg), bovine serum albumin (BSA; 200 mg/kg), soy protein isolate (200 mg/kg), or SDOs (50, 100, and 200 mg/kg). Diabetic rats administered SDOs had a higher body weight and serum insulin but a lower blood sugar than diabetic control rats. Biochemical assays indicated lower AST/SGOT, ALT/SGPT, BUN, and triglycerides but higher HDL in the SDO groups. Immunohistochemistry showed that SDOs reduced damaged islet cells, increased beta-cell size, and improved insulin levels while decreasing alpha cell size and glucagon. The vascular effects of SDOs were like those of normal control treatment and insulin treatment in diabetic rats. SDOs, a yellow silk protein, show potential for long-term diabetes care. Full article

Recently, phosphorylation has been applied to peptides to enhance their physiological activity, taking advantage of its modification benefits and the extensive study of functional peptides. In this study, water-soluble peptides (WSPs) of sea cucumber ovum were phosphorylated in order to improve the latter’s calcium binding capacity and calcium absorption. Enzymatic hydrolysis methods were screened via ultraviolet-visible absorption spectroscopy (UV–Vis), the fluorescence spectrum, and calcium chelating ability. Phosphorylated water-soluble peptides (P-WSPs) were characterized via high-performance liquid chromatography, the circular dichroism spectrum, Fourier transform infrared spectroscopy (FTIR), UV–Vis spectroscopy, surface hydrophobicity, and fluorescence spectroscopy. The phosphorus content, calcium chelation rate and absorption rate were investigated. The results demonstrated that phosphorylation enhanced the calcium chelating capacity of WSPs, with the highest capacity reaching 0.96 mmol/L. Phosphate ions caused esterification events, and the carboxyl, amino, and phosphate groups of WSPs and P-WSPs interacted with calcium ions to form these bonds. Calcium-chelated phosphorylated water-soluble peptides (P-WSPs-Ca) demonstrated outstanding stability (calcium retention rates > 80%) in gastrointestinal processes. Our study indicates that these chelates have significant potential to develop into calcium supplements with superior efficacy, bioactivity, and stability. Full article
