AB  - The aim of this study was to analyze in detail the phytochemical composition of amaranth (AMJ), red beet (RBJ), and broccoli (BCJ) microgreens and cold-pressed juices and to evaluate the antioxidant and sensory properties of the juices. The results showed the presence of various phenolic compounds in all samples, namely betalains in amaranth and red beet microgreens, while glucosinolates were only detected in broccoli microgreens. Phenolic acids and derivatives dominated in amaranth and broccoli microgreens, while apigenin C-glycosides were most abundant in red beet microgreens. Cold-pressing of microgreens into juice significantly altered the profiles of bioactive compounds. Various isothiocyanates were detected in BCJ, while more phenolic acid aglycones and their derivatives with organic acids (quinic acid and malic acid) were identified in all juices. Microgreen juices exhibited good antioxidant properties, especially ABTS•+ scavenging activity and ferric reducing antioxidant power. Microgreen juices had mild acidity, low sugar content, and good sensory acceptability and quality with the typical flavors of the respective microgreen species. Cold-pressed microgreen juices from AMJ, RBJ, and BCJ represent a rich source of bioactive compounds and can be characterized as novel functional products.

AB  - Leaves available as by-products from some crops could be used as a major protein
source for food applications. Here, pumpkin leaves from field crop side streams were used for
the preparation of a protein-rich extract. Namely, pumpkin leaves were mechanically
processed with additional steps of acidic treatment and lyophilization to produce the extract.
The extract (1 mass%) was mixed with a spinnable biopolymer-pullulan (5 mass%) with the
addition of vitamin B12 (vitB12) as a model vitamin. This homogeneous mixture was
electrospuned through a stainless-steel needle (18G) at a steady flow rate of 25.2 mL/h using
a syringe pump and an electric field (17 kV) between the positively charged needle and
grounded metallic collector plate. The starting solutions (plain pullulan-PUL, pullulan with
extract-PUL+E, and pullulan with extract and vitB12-PUL+E+B12) as well as the resulting
structures were analyzed regarding physicochemical and morphological properties.
The addition of the extract increases the surface tension of the PUL solution, but
vitB12 decreases it. On the other hand, the viscosity measurements showed an increase in the
value with the addition of extract and vitB12. PUL solution had a conductivity of 0.163
mS/cm, and the value increased upon adding the extract and vitB12 (1.420 mS/cm and 0.978
mS/cm, respectively). According to SEM images, electrospinning resulted in the formation of
beaded fibers. The lower the viscosity of the solution, the greater the proportion of particles
observed, which is in accordance with literature data. The mean value of the particle size
decreases from 388.89 nm (PUL) to 176.68 nm (PUL+E). However, the addition of vitB12
leads to an increase in the mean particle size to 255.94 nm. The addition of extract didn't have
a strong effect on average fiber diameter, while a slight increase was observed in
PUL+E+B12. FTIR analysis suggests intermolecular interactions between the constituents of
the pullulan-extract-vitamin B12 fibers. As a conclusion, the combination of pullulan and
protein-rich extract has the properties of a stable carrier for the encapsulation of vitamin B12.
