Two linearity factors (ratio of amylose to amylopectin, time of cycle) and six non-linearity factors (ratio of starch to water, time of gelatinization, pH, time of retrogradation, temperature of retrogradation, Ca~(2+)) were obtained.
Result indicated that bread staling can be controlled to a great extent if added 0.09% α-amylase、1% defatted soybean、2%xanthan gum、0.3%monoglyceride、0.1%PGMS and 0.1%TGMS by weight of flour in bread making,while bread quality maintains well during storage.

Some new partial orderings describing aging property
The concept of aging, which is very useful in reliability theory, describes the adverse or beneficial effects of age on the lifetime of systems.
And conversely, a group of new aging classes of life distrbutions can be derived from these orderings.
This paper investigates the effects of postponing retirement on economic growth in an aging society by using the infinite overlapping generations model constructed by Blanchard (1985) in a simple endogenous growth framework.
A systematic investigation was performed on the influence of several factors such as ageing of the reaction mixture, alkalinity, salt addition and temperature on the formation of a mordenite membrane on the seeded support.
The ageing of the reaction mixture reduces the growth rate of mordenite crystal along a-axis and b-axis but hardly influences the growth rate along c-axis.
As a result, the boundaries between the surface crystals become a little larger with prolonging the period of ageing time.
Generalized birth-death processes and their application to the ageing models
The generalized birth-death processes were introduced to model ageing of objects of different nature.
The results of paste properties showed that with increased OSA modification, the starch derivatives had higher paste clarity, decreased retrogradation and better freeze-thaw stability.
The rheological property and retrogradation regulation of amylopectins from three types of rice (indica rice, japonica rice and waxy rice) in China were investigated using concentric cylinder viscometer.
Among the three types of rice, the flow behavior index and retrogradation rate of indica rice paste are the greatest, while waxy rice paste has the smallest flow behavior index and retrogradation rate.
Power function models based on molecular mass are proved suitable for the prediction of retrogradation rate of amylopectin paste.
An additional association analysis was performed between these molecular markers and the thermal and retrogradation properties for a subset of 245 samples from the 509 rice varieties.
Use of electron spin resonance for the determination of staling of roast coffee in polyethylene bag packs
Single effects and interactions between flour type, the breadmaking process and anti-staling additives (i.?e.
These ratios indicate the fermentation degree and possible staling of cocoa beans.
In this research, the effects of lactic acid bacteria starter and hop additives, similar to yeast, on the quality of the resulting dough and bread, especially the development of staling, were investigated.
Almost all additives had an effect on dough and bread properties, pH and acidity development and, moreover, on the development of staling.
