Effect of cactus pear (Opuntia ficus-indica (L.) Miller) on the antioxidant capacity of donkey milk

2017

The cladodes of Opuntia ficus‐indica (L.) Miller were fed to lactating donkeys as an alternative food, in order to evaluate effects on the chemical composition and antioxidant activity of their milk. Lactating donkeys were divided into two groups: standard feeding and alternative feeding. With regard to chemical composition, no differences were observed. Total antioxidant capacity was constant in the standard feeding group, while it increased in the alternative feeding group: the radical scavenging activity increased from 95.53% to 96.62% in the ABTS test and from 28.40% to 33.33% in the DPPH test. This indicated that alternative feeding affects the antioxidant capacity of milk.

Effect of opuntia ficus-indica mucilage edible coating on quality, nutraceutical, and sensorial parameters of minimally processed cactus pear fruits

2021

Cactus pear (Opuntia ficus-indica (L.) Mill.) is a non-climacteric fruit with a relatively short postharvest life span, being very sensitive to water loss, darkening and decay. Cactus pear is a spiny fruit, and the presence of glochids limits fruit consumption and diffusion

Physiological and Technical Aspects of Cactus Pear [Opuntia ficus-indica(L.) Mill.] Double Rellowering and Out-of-Season Winter Fruit Cropping

2007

Abstract A commercial cactus pear plantation in Sicily, Italy was manipulated to induce late cropping. The spring flush of flowers and cladodes were removed as was the second induced bloom of flowers and cladodes. The third induced bloom was harvested for a late out-of-season crop of cactus pear (Opuntia ficus-indica Mill.). The double removal induced a third flush of flowers and cladodes during late August with a fruit production that ripened the following winter (to March). The number of flowers per fertile cladode was halved after the double removal and the length of the fruit development period increased from 100-120 days to 160-190 days for the out-of-season crop.

The effect of different amounts of cladode removal on reflowering of cactus pear (Opuntia ficus-indica(L.) Miller)

1994

SummaryThe removal of the spring flush of flowers and cladodes at bloom promotes reflowering in cactus pear. Studies were conducted to investigate the influence of different amounts of spring flush cladode removal (100%, 75%, 50%, 25%, 0%) on cactus pear reflowering. A positive linear correlation between the severity of spring flush cladode removal and the degree of reflowering was found. Primary (spring flush) and secondary (second flush) cladodes showed the same fertility in the year after formation. Two year old cladodes showed a significantly lower fertility and have only a marginal effect on plant yield.

Life Cycle Impact Assessment applied to cactus pear crop production for generating bioenergy and biofertiliser

2020

Among the potential uses of cactus pear, the generation of bioenergy (biogas) and biofertiliser (digestate), from the Anaerobic Digestion (AD) of cladodes and fruits, is surveyed in this paper. Data for Life Cycle Impact Assessment (LCIA) was drawn from a farm located in Roccapalumba (Palermo, Sicily, Italy), where three cultivars were cultivated: 1) yellow pulp cultivar; 2) red pulp cultivar; 3) white pulp cultivar. LCIA was applied to six scenarios: 1) current dry crop; 2) current irrigated crop; 3) dry crop for fruit and bioenergy production; 4) irrigated crop for fruit and bioenergy production; 5) dry crop for bioenergy production; 6) irrigated crop for bioenergy production. According t…

EVOLUTION OF ENDOGENOUS GIBERELLINS AT DIFFERENT STAGES OF FLOWERING IN RELATION TO RETURN BLOOM OF CACTUS PEAR (OPUNTIA FICUS-INDICA (L.) MILLER)

1998

Abstract The effect of flower emasculation, flower injection with paclobutrazol and the complete removal of the spring flush of flowers and cladodes on the changes in GA 3 concentration at different stages of bloom in flowers and fertile cladodes of Opuntia ficus-indica has been determined. Throughout the bloom period, the concentration of GA 3 was higher in intact flowers and the cladode than in flowers emasculated or injected with paclobutrazol. With the onset of blooming, GA 3 started to accumulate both in the flower and in the fertile cladode, and the highest concentration was measured at full bloom in the flower and in the cladodes whose flowers were not removed. Flower emasculation or…

THE EFFECT OF ROOTS CONFINEMENT ON THE RELATIVE GROWTH OF ROOTS AND CANOPY OF OPUNTIA FICUS-INDICA

Summary The influence of soil volume on roots and canopy growth performance of cactus pear (Opuntia ficus-indica) was studied at Palermo University. In November 2014, 1-year-old Opuntia ficusindica cladodes were planted in five different volumes of soil 50, 33, 18, 9 and 5 Liters. Three replicates (plants) per pot size were dug out at 6 and 12, 18 and 24 month intervals, thus in total, there were 5 x 3 x 4= 60 experimental plots. The resulting experimental design was a completely randomized design with combinations of two factors, soil volume and month of the sampling, with three replications. Roots of each plant were washed and visually divided into three groups depending on their diameter…

Opuntia cladodes as functional ingredient in durum wheat bread: rheological, sensory, and chemical characterization

2021

Cladodes are considered by-products of Opuntia ficus-indica cultivation. Their addition as source of antioxidants to durum wheat breads could have effects on preventing cardiovascular diseases, cancers, and inflammation. The inclusion of 0-5-10-15% cladodes, harvested in three different locations, on quality and antioxidant properties of fortified durum wheat breads has been evaluated. The enrichment with 10% of cladodes resulted in an increase in the content of total phenolics (14.8 vs 2.7 mg GAE/100 g of control bread), a decrease of IC50 (3.28 vs 49.7 mg/ml of control bread), good rheological characteristics of loaves and largely positive evaluation by panel test. Fortification with 15% …

Past and present role of the Indian-fig prickly-pear (Opuntia ficus-indica (L.) Miller, Cactaceae) in the agriculture of sicily

1992

Of prickly-pear cacti occurring in Sicily, the most widespread and economically important is Opuntia ficus-indica (L.) Miller. In Sicily it has, since its introduction, played an important role in the exploitation of marginal areas. The Sicilian experience is described with reference to the historical outlines and the present intensive production of late fruit. Information on historical and actual uses of the plant and its products (flowers, cladodes, fruits) is given.

Silage of Prickly Pears (Opuntia spp.) Juice By-Products

2020

Simple Summary The cactus pear plant is a Cactaceae which originates from the Americas and is highly resistant to arid and hot environments. The plant is used as animal feedstuff in regions characterized by a lack of nutrient resources. In Italy, the fruits are known as prickly pears are usually eaten fresh by humans, and more recently have also started to be transformed into fruit juice. Various by-products (i.e., peel, pulp, and seeds) derived from the extraction of fruit juice are used for livestock feed due to their high amounts of fermentable structural carbohydrates. However, some of these by-products are difficult to conserve due to their high fermentability. The aim of the present s…
