Different Types of Meatballs Enriched with Wild Thyme/Lemon Balm Aqueous Extract—Complex Characterization

In the context of the increasing lactation problems among breastfeeding women, the development of a healthy lifestyle is needed. Different variants of pork, turkey, and beef meatballs, with added lemon balm (Melissa officinalis L.) and wild thyme (Thymus serpyllum L.) aqueous extract (6%), were obtained. These herbs were selected and used due to their antioxidant, antimicrobial, and lactogenic potential. Two thermal treatments, hot air convection (180 °C) and steam convection (94 °C), were applied for meatballs processing. The obtained meatballs were further subjected to a complex characterization. The functionality of the plant extracts was proved by the values of total content of polyphenols (2.69 ± 0.02 mg AG/g dw) and flavonoids (3.03 ± 0.24 mg EQ/g dw). FT-IR analysis confirmed the presence of trans-anethole and estragole at 1507–1508 cm−1 and 1635–1638 cm−1, respectively. Costumers’ overall acceptance had a score above 5.5 for all samples, on a scale of 1 to 9. Further analysis and human trials should be considered regarding the use of lactogenic herbs, given their health benefits and availability

Effects of Heat Treatments on Various Characteristics of Ready-to-Eat Zucchini Purees Enriched with Anise or Fennel

Galactagogue herbs, also known as natural lactation adjuvants, are frequently used to stimulate breast milk production. Due to their antioxidant activity and phenolic content, anise (Pimpinella anisum L.) and fennel (Foeniculum vulgare L.) were chosen to increase the added value of zucchini (Cucurbita pepo L.) purees. At the same time, this work aimed to determine the influence of heat treatment on various characteristics of the final product. The phytochemical content, color parameters, and rheological and textural parameters of zucchini purees enriched with herbal aqueous extracts were determined after processing and after one week of storage (4 °C). In the case of antioxidant activity, samples registered a variation between 6.62 ± 1.71 and 38.32 ± 3.85 µM Trolox/g DW for the samples processed by steam convection. The total difference color parameter (ΔE) increased seven times after one week of storage compared to samples at T0. Fennel and anise aqueous extracts helped improve the rheological behavior of zucchini samples both by steam and hot air convection. This study may serve as a springboard for future investigations and clinical trials into the scientific validity and safety of ready-to-eat foods with special destinations

Red Beetroot and Red Capsicum Pepper Purees Boosted with Anise or Fennel Aqueous Extracts

This research aimed to evaluate the changes induced by two thermal treatments on red beetroot and red capsicum pepper, alongside the addition of anise or fennel aqueous extracts to boost lactation. The cooking loss and yield, phytochemical profile, antioxidant activity, in vitro digestion, FT-IR investigations, and respective statistical analysis were performed for all the puree samples. Cooking loss and yield determined similar values for both vegetables used. Comparatively, between hot air and water vapor convection, the latter proved to be a milder method. By the statistical method, the samples mixed with herbal aqueous extracts presented significantly differences (p < 0.05) compared to the blank samples. Also, the samples mixed with herbal aqueous extracts were statistically significantly different from the control samples. Among the experimented samples, steamed red capsicum pepper puree enriched with aqueous anise extract (EAAA) showed the highest antioxidant activity (71.08 ± 1.9 µM Trolox/g DW). These results might mark the implementation of softer thermal methods for food preparation as well as new purposes for plants. FT-IR analysis revealed the presence of esters, glycosidic bands, pyranoid rings, and pectin, which are specific compounds for the evaluated matrices. The total phenolic content evolution was negatively affected only after the first hour of digestion. In conclusion, red beetroot and red capsicum pepper with anise or fennel aqueous extracts could contribute to improving breastfeeding. Even so, clinical tests and further analysis are necessary in order to confirm the efficacy of such products
