A gelatinized cross-linked high amylose starch matrix with magnetic properties was synthesized via in situ formation of iron oxides inside the polymer matrix. Precipitation and multiple oxidation of ferrous ions were performed. The samples were observed using transmission and scanning electron microscopy, showing morphological changes in the magnetic and polymer phases. The iron content analysi...

Cereal Chem. 78(4):442–446 In this study, 3% aqueous high-amylose maize starch (Hylon VII) dispersions were heated to temperatures of 140–165°C. The onset and rate of gel formation was observed using a small-strain oscillation rheometer as a function of temperature from 90 to 25°C. The gel formation clearly began earlier in high-amylose starch paste preheated at lower temperatures, but the rate...

Ethanol production strategy was studied using multiple strain microbes from microwave irradiation (MI) pretreated sago waste. Sago waste (SW) was MI-pretreated for reducing sugars production using 2 heating media (water and sulfuric acid) under pretreatment conditions including MI power, pretreatment duration, and solid loading. When water was used, the pretreatment parameters were optimized us...

since the dawn of time. In fact they are vitally important to the existence of life itself. Civilizations have used enzymes for thousands of years without understanding what they were or how they work. The modern history of enzymes dates back to 1833 when, in the journal Annales de Chemie et de Physique, the French chemists Anselme Payen and Jean-Franois Persoz described the isolation of an amy...

The advantages of pelleted feed can include improved handling, palatability, and nutrient availability. Poor pellet quality, however, diminish these positive returns lead to customer complaints. Thus, commercial mills may remove fines with a screener after cooling in order provide consistent product customers. There are limited data on the effect returning back mill quality efficiency. objectiv...
