This work evaluates the effect of temperature and soluble solids on degradation rate phenolic compounds, antioxidant activity extracts from Bixa orellana L. leaves. The temperatures were studied in range typical food processes (70-90 °C) storage (−20-37 °C). results showed that thermal compounds follows first-order kinetics, which depends temperature, amount solids, pH. loss also kinetics. Unde...

The objective of this study was to investigate the production microbial cellulase by using Aspergillus oryzae and its application in treatment coffee. producing method used for microbe medium submerged fermentation with malt extract medium. determining activity spectrophotometry at wavelength 540 nm 3,5-DNS reagent measure reducing sugar (the product enzymatic reaction). Then, applied on green ...

Tomato (Solanum lycopersicum L.) is one of the vegetables widely cultivated in world, whose fruits are rich nutrients. Soluble solids content (SSC) important factors affecting tomato fruit flavor and plays a decisive role improving quality. Molecular markers genetic that reveal plant polymorphism at DNA level, which have advantages breeding purposes, increasing selection efficiency, shortening ...

in the current research, salicylic acid and putrescine treatments solutions each with 0, 0.5, 1, and 2 mm/l levels were sprayed on the ‘granny smith’ apple trees in three preharvest stages. the treatments were applied based on factorial experiment in the randomized complete block design. weight loss, fruit firmness, total soluble solids (tss), titratable acidity (ta), ph, tss/ta, peel color, an...

A survey was conducted to determine the quality and yield of 15 major wine grape cultivars. Six Vitis vinifera L., three Vitis rotundifolia Michx., and six French-American hybrid cultivars were included in the survey. Fruit maturation was determined by percent soluble solids, TA, and pH measurements. Soluble solids were attained at the expense of acidity and pH. In spite of low soluble solids a...

damage caused by freezing can be the result of differences in cellular processes, including changes in membrane properties, interactions between macromolecular and enzymatic reactions. in this experiment, total soluble solids (tss) and relative water content of the reproductive buds of cultivars “j. h. hale”, “elberta,” “redhaven, ” “sorkh sefid mashhad” and “amsden” peaches, along with nectari...
