25. Effects of passion fruit peel flour as a dietary fibre resource on biscuit quality
Abstract The purpose of this investigation was to evaluate the effects of the addition of passion fruit peel flour (PFPF) from two different species to biscuits. Each PFPF was added to biscuit flour in different amounts (wheat flour replacement rate: 0%, 5%, 10%, and 15%). The colour and textural properties of the doughs and biscuits were evaluated. The phys

26. MONITORING TRACTOR PERFORMANCE USING SHEWHART AND EXPONENTIALLY WEIGHTED MOVING AVERAGE CHARTS
ABSTRACT Statistical process control has been widely used in agricultural operations for monitoring and improving process quality. This study aims to evaluate the Shewhart and exponentially weighted moving average (EWMA) control charts to monitor the performance of an agricultural tractor–planter set. The design is completely randomized based on the assump

27. Poor sanitation and transmission of COVID-19 in Brazil
ABSTRACT Coronavirus is a family of viruses that cause respiratory infections. From cases first recorded in China at the end of 2019, a new type of virus in this family, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was discovered. The disease caused by this virus, COVID-19, was brought into Brazil by people in social classes with great

28. Straw management effects on sugarcane growth, nutrient cycling and water use in the Brazilian semiarid region
ABSTRACT It was evaluated how straw management modifies the development, growth, nutrient cycling and crop water productivity of sugarcane in the semiarid region of Brazil. The experiment was carried out using two plots with 5 ha each, being one without straw on the soil surface and one with 26 Mg·ha-1 covering the soil. Sugarcane growth and development and

29. Optimization for sensory and nutritional quality of a mixed berry fruit juice elaborated with coconut water
Abstract A new juice market, consisting of mixtures of fruits, is expanding in the beverage segment, in order to increase even more the nutritional and sensory characteristics. In addition, in the preparation of juices, the option exists to replace water with coconut water. The aim of this study was to develop and optimize mixed juices based on coconut water

30. Enrichment of fishburgers with proteins from surimi washing water
Abstract The proteins recovered by ultrafiltration (UF) represent a co-product of fish industrialization and can be used as a protein ingredient in the fortification of food formulations. The objective of this study was to evaluate the quality of surimi fishburger elaborated with the proteins recovered by UF from the wastewater generated in the production of

31. Freezing methods affect the characteristics of large yellow croaker (Pseudosciaena crocea): use of cryogenic freezing for long-term storage
Abstract Large yellow croaker (Pseudosciaena crocea) is the main coastal economic fish in China. After harvesting, the fish is rarely traded as the fresh product, but usually held in cold storage. Therefore, it is important to understand the quality changes occurring during preservation. In this study, freshly collected fishes were frozen by cryogenic (cabin

35. Greenhouse gas emission, water quality and straw decomposition as a function of rice postharvest field management
ABSTRACT The objective of this paper was to evaluate the quality of water drained after the use of the knife-roller (an implement used to incorporate rice residues after harvest), the partial global warming potential (pGWP) and straw decomposition as a result of postharvest field management of irrigated rice. The experiments were conducted during the 2018 an

36. ACHPA: A sensor based system for automatic environmental control in hydroponics
Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production
