“…At this point, public research centers have an important contribution, not only to verify the efficiency of fungicides but also to establish strategies for the efficient use of post-harvest chemical control [15]. Considering the new consumer tendencies, about secure products free of chemical residues, it is necessary to consider the rational use of chemical fungicides without exceeding the MRL [20][21][22].…”

“…According to their results, the applications of these films improve the fruit quality by reducing water losses and the maintenance of appearance of fruit [44]. In a recent study, anthracnose and stem-end rot in the greenskinned on avocado fruits was successfully controlled by the application of thyme oil in combination with a prochloraz solution; besides, this treatment improved fruit quality (firmness) during the storage time [20]. Essential oils of copaiba and eucalyptus were tested against Alternaria alternata and Colletotrichum musae under in vitro, and the results showed good efficacy at low concentrations of the treatments (0.0-1.0%) [45].…”

The effectiveness on several fruits by the application of alternative methods against fungi is summarized in the present chapter. Several investigations have reported the efficacy of these technologies for controlling fungal infections. Currently, high post-harvest loses have been reported due to several factors such as inefficient management, lack of training for farmers, and problems with appropriate conditions for storage of fruits and vegetables. Even now, in many countries, post-harvest disease control is led by the application of chemical fungicides. However, in this time, awareness about fungi resistance, environmental, and health issues has led to the research of eco-friendly and effective alternatives for disease management. The pathogen establishment on fruits can be affected by the application of GRAS compounds like chitosan, essential oils, salts, among others; besides, their efficacy can be enhanced by their combination with other technologies like ultrasound. Thus, the applications of these alternatives are suitable approaches for post-harvest management of fruits.

“…Several other EOs have also demonstrated positive effects on avocado fruit. The fumigation of 'Fuerte' avocado with citral significantly reduced the incidence of stem-end rot by 75% and induced the activity of active defence-related enzymes in the fruit [50]. The application of savory and thyme oils at 2000 ppm presented strong antifungal activity, and significantly reduced expansion of necrotic lesions around the inoculation sites on avocado fruit by 58%-64% [51].…”

“…The advantage of applying thymol fumigation is the elicitation of important defence response at the enzymatic and transcript level making the fruit less susceptible to fungal development post infection (Table 3). As biological fumigants, essential oils elicit the incidence of enzyme activities and genes expressed in fruit after storage and they have demonstrated to have to phytotoxic effect of the pericarp of the fruit when applied as in vapour form [50]. Studies have shown that major constituents of savory oil and thyme oil, which are carvacrol (71.2%) and thymol (73.3%), portray a greater potential as natural fungicides through complete inhibition of the mycelia growth [52].…”

“…This effect was demonstrated through the combination of prochloraz ® (500 µg mL −1 ; P50) with 0.1% v/v thyme oil [52]. A significant reduction in stem-end rot incidence of 10% was observed, while P50 (500 µg mL −1 ) + 0.1% v/v thyme oil induced the activities of phenylalanine ammonia lyase, chitinase and β-1,3 glucanases in avocado fruit inoculated with L. theobromae and C. gloeosporioides [50]. Candelilla wax and antioxidant ellagic acid (0.01 wt%)…”

Developing postharvest management techniques using environmentally friendly and non-chemical approaches is key to extending the shelf life of avocados in a safer and health conscious manner. Avocados are prone to postharvest deterioration caused by mechanical damage, chilling injury, soft landing, uneven ripening and decay. Among the different cultivars of avocados commercially grown worldwide, the ‘Hass’ variety continues to be the most predominant due to its nutty flavour and functional properties. Most of the literature on postharvest decay and disorders affecting avocado fruit quality during storage and marketing is dedicated to the Hass avocado. Some of these postharvest problems are unique to the ‘Hass’ avocado can possibly be controlled by simply investing more research into other cultivars. These postharvest losses can be significantly controlled using eco-friendly technologies, such as modified atmosphere, physical heat treatments and most importantly investing in natural biodegradable products with naturally inherent antimicrobial properties. Thus, this review includes the recent research-based information on the use of non-chemical treatments on the improvement of fruit health and quality.

Avokado, zengin besin bileşimi ve önemli miktarda yağ içeriği ile öne çıkan bir tropikal meyvedir. Taze meyve olarak tüketiminin yanı sıra günlük diyette avokado içerikli ürünlere olan arz ve talep artmaktadır. Avokadonun besin değeri ve yararlarını araştıran çalışmalarla birlikte, üretim miktarı ve yeni kullanım alanları da günden güne artmaktadır. Avokadonun işlenmesindeki en önemli sorun meyvenin hızlı renk değişimine uğraması ve fiziksel, kimyasal ve mikrobiyolojik etkenler nedeniyle raf ömrünün kısa olmasıdır. Bu sorunların etkisi, meyvenin işlenmeden önce ısıl işlem, düşük sıcaklıkta koşullandırma, yüzey kaplama, modifiye/kontrollü atmosfer ve 1-metilsiklopropen kullanımı gibi uygulamalara tabii tutulması ile azaltılabilmektedir. İyi kalitede ve işlenebilecek nitelikte olan avokado meyveleri hedef pazara bağlı olarak ve uygun teknolojiler kullanılarak yağ, guakamol, püre, sos, taze dilim, kurutulmuş veya dondurulmuş ürün olarak işlenmektedir. Bu derlemede belirli kalite kriterlerine sahip avokado meyvelerinin işlenmesi ile oluşan ve günden güne gelişmeye devam eden avokado bazlı ürün pazarı ele alınmaktadır.
