“…It is also important here to stress, the higher phenolic content in P. americana byproducts compared with the edible pulp (Wang et al, 2010). This greater polyphenolic content has also displayed higher antioxidant capacity, and as expected P. americana peels proof to excel the kernels activity in around 1.5-fold higher in all the antioxidant tests performed and shown in Table 2, this result proved to be in concordance with Calderón-Oliver et al (2016), Kosińska et al (2012) and Saavedra et al (2017). Although the differences in the total phenolic content between peels and kernels is 3 times higher, the antioxidant activity observed it is only around half (1.5) greater.…”

The results here exposed shown better performance when compared with the results reported by (Calderón-Oliver et al, 2016;Chia et al, 2010). Contrary to bactericidal effect, fungicidal effect only was shown in 2 strains but only with kernel extracts, from which, the better fungicidal effect was against Trichoderma viride.…”

“…There are several varieties within the P. americana species such as Bacon, Hass, Fuerte, Gwen, among many others, being Hass one of the most commercialise varieties. Hass avocados has around 14% and 16% of total fruit weight in its peels and kernel, respectively, accounting around 30% of its weight on by-products (Calderón-Oliver et al, 2016). The peels and pulps of many fruits, including avocado, contain a large amount of antioxidants that are responsible for the plant defence system, against different types of stresses, such as temperature and light (Ghasemzadeh and Ghasemzadeh, 2011;Manach et al, 2004).…”

A B S T R A C TAvocado (Persea americana Mill.) is a worldwide consumed fruit, with great interest for cosmetic and pharmaceutical industries; however, 30% of avocado fruits are bio-wastes (peels and kernels), converting them into a potential source of bioactive compounds, such as phenolic compounds. Therefore, the hydroethanolic extracts of peels and kernels of Persea america Mill. var. Hass were analysed regarding their individual phenolic profile by HPLC-DAD/ESI-MS and correlated with their antioxidant, antimicrobial and cytotoxic activities. Avocado byproducts presented a very distinct phenolic profile, presenting higher concentration in peels (227.9 mg/g of extract for total phenolic content), mainly in (epi)catechin derivatives (175 mg/g of extract), followed by chlorogenic derivatives (42.9 mg/g of extract). In this study hydrophilic and lipophilic antioxidant assays were performed together for the first time in P. americana by-products, and although kernels showed a great antioxidant potential (EC 50 values ranging from 18.1 to 276 μg/mL), peels presented the highest potential (EC 50 ranging from 11.7 to 152 μg/mL), mainly due to the presence of phenolic compounds, and an overall better performance in the antibacterial assays. Further studies needs to be conducted to better understand the correlation between the presence of phenolic compounds and bioactivities, however, the main objective is to implement these biocompounds in different products and industries, due to results obtained, P. americana peels could be a great alternative in the substitution of synthetic antioxidants.

This study evaluated the incorporation of microcapsules containing nisin and avocado peel extract on the shelf life of ground beef. Ten treatments were studied and divided into two groups: one packaged under vacuum and the other in permeable packaging. Each group contained: (a) control, (b) extract, (c) nisin, (d) empty microcapsules (only wall microcapsule system), and (e) microcapsules with extract and nisin. The samples containing the microcapsules presented lower bacterial growth and less oxidation. On day 10, the vacuum‐packaged samples with microencapsulated preservative presented a reduction in the oxidation of proteins of approximately 45%, of 30% in the growth of mesophiles, and of 38% in the growth of coliforms, as well as a reduction in the changes in the pH and ɑW that occur during storage, compared with the permeable control. The combination of microcapsules with vacuum packaging reduced the physicochemical and microbiological changes that occur in the controls.
