After microwave drying, the highest amounts of ash, fat, fiber, and protein with values 6.39 ± 0.04, 10.10 ± 0.05, 10.14 ± 0.06, and 13.10 ± 0.03<i>%</i>, respectively, were observed in coriander seeds.

Resistant dextrin, a low-calorie, indigestible water-soluble dietary fiber processed from starch, has high solubility, low molecular weight, and good thermal stability. The established method for its preparation involves a combination of acid heat treatment and enzymatic purification. Within the human body, resistant dextrin confers numerous health benefits. It promotes a balanced intestinal microbiome, regulates blood glucose and lipid metabolism, and enhances satiety. Additionally, it exerts positive influences on the intestinal environment, aids in weight management, and alleviates chronic conditions, particularly diabetes. In the food industry, resistant dextrin is widely employed as a functional food additive to enhance the nutritional value and health benefits of various food products. However, there is a need for greater clarity regarding the structural characteristics of resistant dextrin and the potential interplay between its structure and physiological activity. This paper comprehensively reviews the preparation methods, structural properties, health benefits, and application areas of resistant dextrin.

In this study, Roselle calyx extract was prepared to which sugarloaf pineapple pulp, Roscoe ginger, Negro/Ethiopian pepper, and cloves were added to obtain the Bissap stock (control). Then, either sucrose, caramel, honey, or sucralose was added to the Bissap to achieve a comparable sweetness (13.1°Brix), and the effects were assessed during storage.

Thermal pasteurization is the conventional method to preserve fruit juices, but it causes undesirable changes in the physicochemical and nutritional value of the juices. Therefore, there is a need to develop alternative methods to ensure the microbial safety and quality of fruit juices. The aim of this study was to investigate the impact of thermal (95-100°C for 4 min), ultrasonication (US) (25 kHz for 5 and 10 min), and thermosonication (TS) (25 kHz at 40 and 50°C) processes on the quality profile of watermelon-beetroot juice blend, a novel juice formulation with enhanced nutritional and functional properties with 50 : 50 formulation. The samples were analysed for physicochemical (colour, pH, total soluble solids, and titratable acidity), bioactive (phenolic, flavonoid, antioxidant, and ascorbic acid contents), and microbiological (total plate count and yeast/molds) properties. The results showed that all the processed samples retained high total phenolic (756.33-842.33 <i>μ</i>g GAE/g), total flavonoid (435.33-512.67 <i>μ</i>g CE/g), and ascorbic acid (45.23-50.34 mg/100 mL) contents along with a high antioxidant potential (total antioxidant capacity (274.14-305.33 <i>μ</i>g AAE/g) and DPPH radical scavenging activity (33.05-42.18%)) while preserving the normal physicochemical characteristics and decreasing the microbial counts of all the processed blend juices.
