13. Changes in sugar contents and invertase activity during low temperature storage of various chipping potato cultivars
Abstract Storage of tubers is vital for uninterrupted supply to potato chips/fries industry. Cold storage is preferred to maintain tuber quality. However, prolonged storage at low temperature results in cold induced sweetening (CIS) leading to sugar accumulation and browning of chips. Slowing down the CIS is of economic importance for potato industry. Screen

14. Activity of polyphenoloxidase and peroxidase in non-dormant potato tubers treated with sprout suppressors
Abstract One of the major problems affecting potatoes quality on stored is the susceptibility to enzymatic browning, which occurs mainly after wounds during the harvest, at postharvest handling and by aging, leading to the development of dark color compounds. Enzymatic browning is associated with the action of polyphenoloxidases (PPO) and peroxidases (POD),

16. CAROTENE YIELD IN SWEET POTATO AFTER POTASSIUM AND PHOSPHORUS FERTILISER APPLICATION
RESUMO A batata-doce é um dos alimentos de maior importância no mundo. Dentre os diferentes genótipos cultivados, merece destaque aqueles de polpa alaranjada, devido a sua capacidade de fornecer quantidades adequadas de carotenóides pró-vitamina A aos seres humanos. Assim, objetiva-se com o desenvolvimento deste trabalho avaliar o efeito de adubação c

17. Artificially cooling of onion bulbs stored in brickwork-patterned vertical silos
RESUMO A cebola é a terceira hortaliça mais consumida no mundo, ao lado da batata e do tomate. Sua conservação é influenciada pela umidade e temperatura e, as maiores perdas pós-colheita ocorrem devido à falta de infraestrutura no armazenamento. O objetivo do presente trabalho foi avaliar o efeito do resfriamento parcial de silo vertical na conservaç

18. A SIMPLE EQUATION FOR TOTAL REDUCING SUGARS (TRS) ESTIMATION ON SWEET POTATO AND ETHANOL YIELD POTENTIAL
ABSTRACT Sweet potato is an attractive feedstock for ethanol production due to its high starch content and favorable agronomic characteristics. This paper proposes a simple equation to estimate the total reducing sugars (including glucose from starch) in sweet potatoes based on their moisture content (low cost and simple measurement). It allows the calculati

19. DRYING KINETICS OF THE SLICED PULP OF BIOFORTIFIED SWEET POTATO (Ipomoea batatas L.)
ABSTRACT Biofortified sweet potato (Ipomoea batatas) is one of the foods with the highest contributions of carotenoids in the diet, especially provitamin A carotenoids. Thus, this study aimed to analyze the drying kinetics of the biofortified sweet potato pulp using the Akaike (AIC) and Schwarz's Bayesian (BIC) information criteria for model selection, as we

20. Physiological characterization of plant growth in sweet potato
RESUMO O objetivo deste trabalho foi caracterizar o crescimento da planta e determinar a melhor época de colheita da batata-doce, considerando raízes e parte aérea (ramas). O trabalho foi realizado no campus JK da Universidade Federal dos Vales do Jequitinhonha e Mucuri, em Diamantina-MG. O delineamento experimental foi blocos ao acaso, com quatro repeti�

21. Action of Essential Oils on Sprouting of Non-Dormant Potato Tubers
ABSTRACT The breakdown of dormancy and early sprouting is one of the main causes of losses of stored potatoes. Sprouting control becomes important especially when tubers are submitted to long-term storage for further processing by the potato industry. The objective of this work is to evaluate the effect of organic sprout inhibitors, eugenol and menthol essen

22. Ecofriendly Synthesis of Silver Nanoparticles Using Potato Steroidal Alkaloids and Their Activity Against Phytopathogenic Fungi
ABSTRACT In order to reduce the excessive reliance on the toxic chemical fungicides, the present study aimed to isolate the total potato glycoalkaloids (TPAs), and the two steroidal alkaloids α-chaconine and α-solanine from potatoes, Solanum tuberosum L. Their structures were characterized using physical and spectroscopic methods including (UV, IR, 1H, 13C

23. Physicochemical and sensory characteristics of sweet potato chips undergoing different cooking methods
Abstract The current study aimed to evaluate the feasibility and acceptability of sweet potato chips from three cultivars undergoing different cooking methods. The sweet potatoes used were cream peel with yellow-flesh, pink peel with yellow-flesh and white peel with white-flesh. Fresh tubers were characterized in terms of centesimal composition and the follo

24. Evaluación de menús ofertados em comedores escolares: comparación entre colegios públicos, privados y concertados
ABSTRACT Objective: To evaluate menus offered in public, private and charter schools in the city of Seville (Spain) for different groups of school children. Methods: A total of 86 schools were evaluated, including public, private and charter schools, which represented every district of the city. Four schools possessed their own kitchen, while the others ha
