Abstract:

Coffee grown in the United States represents less than 1% of the world's supply, and most of it comes from the state of Hawai'i. Kona coffee, grown on the western side of the island of Hawai'i, is the most recognized and the highest value Hawaiian coffee. The majority of this coffee is sun-dried after harvest and washing. Sun-dried coffee should reach 12-13% moisture within 4 to 6 days. Sun-drying will reduce both the moisture content and the water activity (aw). Reducing aw below 0.75, especially in the first week of drying, is important for preventing or limiting mold growth. The purpose o

The post-harvest quality of perishable produce changes rapidly due to the accelerated rate of respiration, transpiration and ripening. The objective of this study was to determine the effect of pectin and alginate based composite coatings on the shelf life extension of cherry tomatoes and to study the effect of an abiotic stress on enhancing antioxidant properties of cranberries. Two composite coating formulations were evaluated, a pectin based formulation with 3% pectin, 1.35% sorbitol, 1.2% bees wax and 0.36% monoglycerides, and an alginate based formulation with 2% alginate, 1.35% sorbitol,

Abstract:

Strawberries are a popular fruit with a pleasing color and flavor. However, its delicate tissue and high sugar content makes it highly perishable with visible mold. In this study, we have attempted to test feasibility of different edible coatings for extending shelf life of ‘Chandler’ strawberries subjected to simulated vibrations of local transportation. Six types of coatings were compared based on the quality of treated berries. Curcumin and limonene were used as natural antimicrobials and coatings were prepared from their liposomes and were over-coated with methyl cellulose. One set of each

Transport and handling were investigated using a novel ‘electronic sweet potato’ where it was found that it was the large number of minor vibrational type impacts that cause the most root damage. Reducing the sack weight and using fibreboard boxes reduced damage. A shelf-life investigation into the types of injury occurring through

Abstract:

Tomatoes are widely produced and consumed due to their nutritional content and versatility. However, the tomato is a soft fruit liable to damage and flavour deterioration. Hence, the main challenge for the tomato producing industry is to prevent the high loss incurred during harvest, handling and transportation of the crops. The objective of this study was to investigate the overall nutritional implication of controlled storage of tomatoes using ozone on the ripening process and the basic nutritional components of tomatoes.

Resumo: O processamento mínimo de frutas é uma das principais técnicas em ascensão no mercado, seguindo a tendência mundial do consumo de produtos in natura ou mais próximo possível destes. Por outro lado, as frutas minimamente processadas ainda são um desafio, devido à falta de conhecimento a respeito do comportamento fisiológico e bioquímico desses produtos. Com isso o trabalho tem como objetivo obter informações sobre goiaba minimamente processada, nas cultivares Século XXI, Sassaoka e Paluma, bem como embalagens mais adequadas no processo. O experimento foi conduzido no laboratório de Tecn

Abstract:

O cajueiro (Anacardium occidentale L.) Ã uma planta de grande importÃncia econÃmica para o Nordeste brasileiro, pela diversidade de produtos proporcionados pelo fruto e pedÃnculo e pela quantidade de empregos gerados. Apesar disso, inexiste uma padronizaÃÃo nos sistemas de produÃÃo empregados, com reflexos negativos na produÃÃo e qualidade da matÃria-prima destinada ao consumo e Ã indÃstria. A conversÃo dos sistemas de produÃÃo vigentes para o sistema de produÃÃo integrada poderÃ contribuir para atenuar este quadro. O objetivo deste trabalho foi comparar os sistemas de produÃÃo integrada e con

Este trabalho teve por finalidade avaliar os efeitos de temperatura nos metabolismos de couves-flores e rúculas inteiras e minimamente processadas e diferentes materiais de embalagem na sua qualidade. No primeiro experimento, couves-flores, seus floretes, rúculas e suas folhas foram mantidos a 1º, 5º e 11ºC e determinados suas taxas de respiração, produção de etileno e quocientes de temperatura (Q10). No segundo, os floretes foram colocados em embalagens de filmes de polietileno de baixa densidade (PEBD), poliolefínicos coextrusados (PD 941 e Clysar) e de policloreto de vinila, PVC esticável

La production de dattes ne cesse d’augmenter d’une saison à une autre ce qui engendre des pertes essentiellement lors des étapes de manutention et de commercialisation. De plus, l’étape de manutention post-récolte joue un rôle important dans le maintien de la qualité des dattes. Dans ce cadre et afin de préserver les qualités organoleptique et nutritionnelle des dattes après récolte tout en améliorant leur valeur commerciale, des essais de conservation et de traitement post-récolte ont été mis en place.

O Brasil é o segundo maior produtor e exportador de soja (Glycine max L. Merrill) no mundo. A produção é altamente dependente de fatores climáticos, incluindo a temperatura e quantidade de chuva. A soja cultivada no sul do país em 2005 sofreu déficit hídrico causado por temperaturas altas acompanhado por umidade baixa durante o estádio reprodutivo. Pouco se sabe sobre a influência do déficit hídrico na degradação da clorofila e na qualidade dos grãos em geral.

This Project identified the relationships between storage conditions, dry matter losses (DMLs) caused by Fusarium species in cereal grains and mycotoxin contamination and assessed novel control strategies for post-harvest grain management including chemical control and ozone. F. graminearum, F. verticillioides and F. langsethiae were inoculated on wheat, maize and oats and stored under environmental conditions where marginal to optimum spoilage and mycotoxin contamination can occur. DMLs were calculated from the CO2 produced and were significantly correlated with deoxynivalenol (DON), zearalen

Fragaria ananassa, generally known as strawberry is a nutritious fruit that is rich in polyphenols and widely consumed as part of a healthy diet. Anthocyanins have been found to be the main group of phenolic components present in strawberry with pelargonidin-3-glucoside as the major component in all strawberry cultivars studied. The main volatile component has been identified as caryophyllene oxide, a sesquiterpene compound that was present abundantly in all cultivars.

Elderberry is very popular plant, that is due to its beneficial effects to human organism very reputable. The main content substances are flavonoids and anthocyanins. Fruits of this flower are available only seasonally (which is usual for most of flowers), so we have to search for alternative solution of getting them. One of these solutions is conservation. Nowadays there are lots of types of postharvest adjustment, so we have more opportunities to find an optimal concept for every one specific plant.

This study focuses on investigating the effect of post-harvest handling conditions and storage time on the dehulling efficiency and cooking quality of two varieties of red lentils, as well as optimizing the dehulling conditions. The effects of storage time, storage moisture content and storage temperature, as well as the effect of different storage pre-treatments aiming to simulate post-harvest handling, were studied. Dehulling efficiency was mostly affected by the pre-milling moisture content, regardless of the storage conditions. Pre-treatments involving moisture content changes lowered th
