Abstract:
... When the recipient of the product is relatively distant from the production area, it is necessary to use cold storage and controlled humidity to transport the avocado fruits. One of the main advantages of local avocado consumption lies on the possibility of prolonging on-tree maturation; this could foreseeably modify the metabolic profile of the fruit that reaches the consumer. In this work, the e ...

Abstract:
... This study focused on the analysis of the pyrolytic behavior of four lignocellulosic biomasses: avocado stone (AS), Agave salmiana bagasse (AB), cocoa shell (CS), and α-cellulose (CEL). According to the triplet kinetics analysis, the order of pyrolytic decomposition was AS < AB < CEL < CS. The AS was dominated by a second-order reaction, while AB followed a 2D diffusion-Valensi model. On the other ...

Abstract:
... Persea americana (avocado) represents one of the most demanded food products worldwide, with an important impact in several agronomy-based economies. The avocado is one of the most salt-sensitive and valuable crops. It is therefore necessary to use salt-tolerant varieties, such as the West Indian, for cultivation in locations with soil salinity problems, such as the Canary Islands. Therefore, char ...

Abstract:
... Avocado pulp is highly susceptible to deterioration. The objective of this work was to evaluate the physicochemical and antioxidant properties of avocado powder with and without ginger extract. Ginger extract and inlet temperature at 160°C improved antioxidant properties measured by DPPH inhibition (62.51%), FRAP (118.44 mg TE/g powder), and ABTS (53.35 mg TE/g powder), while the use of a higher s ...

Abstract:
... Avocado fruits were collected throughout the season from California, USA and Michoacan, Mexico. Oil was made from high quality, Grade 1, and low quality, Grade 4, avocados from both regions using a laboratory-scale oil extraction mill through physical means. For each grade, oil was made from whole fruits and only the mesocarp. The impact of each of these parameters on free fatty acidity, peroxide ...

Abstract:
... Flower visitors use different parts of the landscape through the plants they visit, however these connections vary within and among land uses. Identifying which flower‐visiting insects are carrying pollen, and from where in the landscape, can elucidate key pollen–insect interactions and identify the most important sites for maintaining community‐level interactions across land uses. We developed a ...

Abstract:
... Lutein and zeaxanthin—xanthophyll carotenoids with antioxidant and anti-inflammatory characteristics—are present in the retina and the brain. High concentrations of these carotenoids have been positively related to cognitive performance. Therefore, this systematic review analyses the relationship between macular pigment density and cognitive functions. Most relevant databases were scoured for stud ...

Abstract:
... ‘Hass’ avocado fruit are usually packed the day after harvest and then immediately cooled and held no more than a few days before export. This procedure is considered to maximise the storage life and quality of the fruit. However, for packhouse logistics, there are times when it may be advantageous to aggregate fruit over a period of days before packing. It is hypothesised that the time at which f ...
... Vegetable and fruit security plays a crucial role in the Indian economy. In the recent past, it has been noted that vegetables and fruits are affected by different diseases. This leads to the failure of the economy in the agriculture field. The identification of type and grading of vegetables and fruit is onerous due to the heavy production of products. The manual investigation is expensive, labor ...

Abstract:
... The current study evaluated the effect of mushroom cultivation using fruit waste substrates on yield performance and antioxidant activities. The total phenolic content and the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities of the mushroom extracts were determined using colorimetric method. Mushroom P. eryngii had the highest yield of 87.2 ± 2.4 g/100 g dry substrate when grown ...

Abstract:
... Avocado is one of the most important fruits with a high nutritional content; this fruit is consumed and cultivated worldwide. It is originally grown in Central America and the West Indies islands. But it is now cultivated in the tropical and subtropical regions of the world. Avocado waste is an abundantly available raw material that can be converted into adsorbents to remove different pollutants f ...

Abstract:
... Food residues have a high potential for extracting components of interest to humans, such as phenolic acids and flavonoids. For example, two residues are generated while processing fruits such as avocado: seed and peel. Both residues include components of interest, such as quercetin and catechin. These compounds have different applications, especially in the pharmaceutical industry. Supercritical ...

Abstract:
... Mexico ranks 5ᵗʰ in worldwide resin production. Pinus oocarpa is the most widely tapped pine tree in Mexico. Michoacán (central-western Mexico) is the first nationwide state producer of resin. Despite the P. oocarpa relevance, there is no genetic improvement program in the country for resin production. We evaluated the degree of genetic control for growth, anatomical traits, resin yield, and the c ...

Abstract:
... The surging demand for commodity crops has led to rapid and severe agricultural frontier expansion globally and has put producing regions increasingly under pressure. However, knowledge about spatial patterns of agricultural frontier dynamics, their leading spatial determinants, and socio-ecological trade-offs is often lacking, hindering contextualized decision making towards more sustainable food ...
... The ability of cotton fabrics to absorb water creates several problems, such as providing an environment for bacterial growth. Antibacterial properties of textiles can be conducted by coating with nanoparticles with antibacterial activity. This study aimed to synthesize ZnO via green process nanoparticles using avocado seed extract (Persea americana), then characterize and evaluate its antibacteri ...
... Avocado (Persea americana Mill.) is an economically important fruit in tropical and subtropical regions of the world. Anthracnose is the most common and serious postharvest disease of avocado fruits. The disease is caused by different species of Colletotrichum in different countries.
