Food and Machinery
In view of the limitations of the traditional processing technology of Pidan, this review summarizes the innovative processing technologies of Pidan, such as gradient temperature control, ultrasonic assisted, vacuum decompression, pulsating pressure, etc., and describes the changes of water, pH value, protein, free amino acids, texture, mineral elements and micro-morphology during the picking process of Pidan. Moreover, the development directions of Pidan products are prospected.

Food Structure
An improved method is proposed for isolation of fat crystals with isobutanol, followed by fixation using osmium tetroxide vapours or cryo-fixation and visualization in the Scanning Electron Microscope (SEM). The cryo-fixation method revealed the presence of well defined needle-shaped or rod-shaped fat crystals. The osmium fixed crystals did not appear as distinct. The crystals existed as single crystals, platelets and spherulites. Polarized light micrographs did not show the details of the crystal morphology that were observed in the SEM.

Food Structure
Histological changes in wiener batters during chopping and cooking have often been illustrated with "representative" fields . The practice of selecting representative fields ignores variation and leads to word descriptions that cannot be correlated with numerical scores for functional or sensory tests . If wieners are regarded as a multi-component system, objectivity can be achieved by selecting many fields for each sample according to a rigid sampling plan. Image analysis quantified parameters of both the fat and protein components . The reduction in size of fat globules during chopping of a commercial formulation, for example, was a function of area …
