The aim of this study was to develop and characterize reduced-fat ice cream formulations with the addition of dehydrated cassava bagasse (CB) and lychee pulp (LP). The ice cream formulations were prepared with different proportions of palm fat (0 to 5%), CB (0 to 5%) and LP (1 to 8%) and were evaluated in terms of chemical and microbiological composition, and in relation to the technological, antioxidant and sensory properties. The use of higher levels of CB (5%) and LP (8%) allowed obtaining a higher fiber content and lower fat content. All formulations were safe for consumption and showed adequate values for overrun, melting rate and color. The ice creams showed adequate sensory acceptance, with emphasis on the formulations containing different amounts of CB addition (2 to 5%) and until 3% LP. The higher LP content the higher total phenolic content and the antioxidant capacity were found in ice cream formulations. These results showed the viability of applying CB and LP in ice cream formulations, especially in the proportion of 5% and 1%, promoting the sustainability by using a natural source of antioxidants and a fiber-rich agro-industrial by-product.

Beetroot is rich in nutrients and bioactive compounds, such as, betalains and phenolics. The objective of this work was to analyze the chemical composition and antioxidant properties of beetroot parasitized by Meloidogyne javanica and treated with elicitors. Beetroot seedlings were inoculated with 1000 eggs and second-stage juveniles of M. javanica and treated with elicitors based on mannan oligosaccharides, citrus biomass, or acibenzolar-S-methyl (ASM). At 60 days after inoculation, plants were evaluated for nematode reproduction factor (RF), proximate composition, betalains, phenolic compounds, and antioxidant activity. Beetroot was found to be susceptible to M. javanica, with RF values ranging from 15.26 to 27.94. ASM and citrus biomass treatments increased ash content by 15-25% in nematode-inoculated plants. There was no treatment effect on moisture or protein content, but uninoculated plants had higher total phenolic content (~35%) than inoculated plants. Nematode infection was found to compromise betalain production but did not impact antioxidant activity. Nematode-inoculated plants showed reduced sucrose content and increased glucose and fructose levels in all treatments. Regardless of the elicitor used, beetroots inoculated M. javanica exhibit deformities that render them unmarketable in fresh form. However, the results indicate that nematode-infected beetroot may be suitable for industrial processing and compound extraction. [ABSTRACT FROM AUTHOR]
