BACKGROUND Starch is the major component of potato tubers, amounting approximately to 150-200 g kg (-1) of the tuber weight. Starch is considered to be a major factor for the functionality of the potato in food applications. This study evaluated the physical characteristics of potato starches isolated from tubers of different potato cultivars grown in soil with three levels of phosphorus (P) av...

Cereal Chem. 81(4):527–532 Differential scanning calorimetry (DSC) is used routinely to screen for starch thermal properties. In early generations of line development, the established analysis separately evaluates starch extracted from five, single corn kernels. A thermal property trait carried by a recessive gene would appear 25% of the time; thus, if five separate kernels were evaluated, the ...

The objective of this work was to study the techno-functional properties alkalineextruded Cuzco corn flour (HMEA) obtained by Ca(OH)2 addition in extrusion process and compare it with those a traditional (HME). native meal conditioned at moistures 30, 35, 40 45% (w/w) extruded single-screw extruder 80 °C. For alkaline extrusion, 0.25 g 100 added. significantly affected HMEA increasing solubilit...

a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...

Starch digestion in the human body is typically viewed in a sequential manner beginning with α-amylase and followed by α-glucosidase to produce glucose. This report indicates that the two enzyme types can act synergistically to digest granular starch structure. The aim of this study was to investigate how the mucosal α-glucosidases act with α-amylase to digest granular starch. Two types of enzy...

Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...

Palo (Curcuma leucorrhiza) starch is isolated from palo tuber, which is better known as hidden lilly and distributed in the hilly areas of Orissa, West Bengal, Jharkhand and Chhatishgarh. Its rhizomes are good source of starch. The starch extracted from the rhizomes has good application as herbal medicines, different foods and food ingredients such as palo laddu which is used specially during f...

Ohmic heating offers an alternating to conventional heating because it simultaneously heats both phases by internal energy generated through electrical energy. In this process heating rate depends upon the electrical conductivity and field strength. By this method a product undergoes a minimum structural damage, retain its nutritional value. This technique gives excellent processed quality prod...
