The aim of this study was to compare the sensory quality and acceptance of dried ready-to-eat beetroot snacks as a result of different drying methods applied: supercritical CO2-drying (scCO2-drying), frying, and freeze-drying. Descriptive sensory analysis, quality rating (10 assessors), and consumer acceptance testing (n = 102) were performed. Mean overall quality scores within the range of “very good” quality were found only in non-precooked scCO2-dried samples which were characterized by typical magenta color, low level of shape and surface deformations, pronounced brittleness and crispiness, and good rehydration during mastication. The other samples were in the range of “good” quality. The pre-cooking step before scCO2-drying negatively influenced the sensory quality parameters, particularly appearance. Around 60% of tested consumers showed a preference for the fried and non-precooked scCO2-dried samples. The drivers of liking were mostly related to the characteristics of the product, which was salted, fried, and crispy, with an oily and overburnt flavor, i.e., the product most similar to commercial potato chips products. Freeze-drying had a negative effect primarily on appearance and flavor. According to the sensory evaluation conducted, direct scCO2-drying without a pre-cooking step showed itself as a promising alternative drying technology in the production of dried beetroot snacks.

Insulation Performance

Cellulose hydrogel was prepared by using the NaOH/ Thiourea/ H2O as solvent system, cellulose aerogels were obtained by freeze-drying technology. The results showed that cellulose aerogel had porous network structure. Freeze-drying method was an effective way to prepare cellulose aerogel, and the volume shrinkage was 20.41%-28.36%. Bulk cellulose aerogel had low density, high porosity and fine mechanical strength. The density was low to 0.233g/cm3, and the porosity was up to 84.88%. The compressive strength was 5.7-8.2MPa. Cellulose aerogel had good heat insulation performance and thermal conductivity could be as low as 0.029 W/ (m·K). This work provided a foundation for the possibility of applying cellulose aerogels in the insulating material field.

A kind of drug release bionic scaffold with gradient structure was designed to release drugs. The scaffold mould had been designed with CAD software and fabricated with rapid prototype. The bionic beta-tricalcium phosphate (β-TCP) scaffold was fabricated with freeze drying. It was composed of two coaxial cylindrical porous scaffolds. The internal loose scaffold was embedded in the outer dense layer. The two different density layers of the scaffold could be used to adjust the drug releasing rate through regulating the slurry concentration. The scaffold was distributed with pores ranged from 30μm to 100μm. The research indicated that the scaffold with gradient structure could be loaded with two kinds of drugs which were released at different rate. The scaffolds were fit as the substitute materials for bone repairing.
