Compost stability and maturity are important parameters of compost quality. To date, nearly all compost characterization has been performed using samples freshly collected because sample storage can affect compost stability and maturity evaluation. However, sample preservation is sometimes necessary, especially for scientific research purposes. There is little information available on the effec...

Butter is often stored for extended periods of time; therefore, it is important for manufacturers to know the refrigerated and frozen shelf life. The objectives of this study were to characterize the effect of refrigerated and frozen storage on the sensory and physical characteristics of butter. Fresh butter was obtained on 2 occasions from 2 facilities in 113-g sticks and 4-kg bulk blocks (2 f...

This work aimed to establish an effective approach to evaluate the quality of frozen fish, focusing on changes in fish tissue structure and chemical composition during storage. Fresh tilapia samples were treated by coating with tangerine peel (TP) extract and then stored at -4, -8 and -18 °C, respectively, for 40 days. The frozen fish tissues were analyzed for structural and chemical changes. F...

introduction: bread stales and unfortunately it is a certainty and causes significant product waste all over the world.staling results in loss of important sensory parameters of bread, like flavor and texture, and it is a consequence of a group of several physical–chemical changes occurring during bread storage that lead mainly to an increase of crumb firmness and loss of freshness (gray and be...

Two studies were conducted to evaluate the quality characteristics of fresh sausage manufactured from immunologically castrated (IC) pigs, an emerging technology in the pork industry. Study 1: Fresh sausage patties from ground Boston butts fabricated from PC (physically castrated) pigs fed 0.55% SID (standard illeal digestible) lysine, IC pigs fed 0.55% SID lysine, and IC pigs fed 0.65% SID lys...

Background/aims—The use of “fresh” (hypothermically stored) and frozen amniotic membrane (AM) was compared in a patient with cicatricial pemphigoid with stem cell failure. The viability of both “fresh” and frozen AM epithelial cells was assessed after storage. Methods—AM was stored at either +4°C (“fresh”) or at −80°C (frozen). A “fresh” graft was applied to the cornea following superficial ker...

A method is described for preservation of blood for delayed determinations of ammonia by rapid freezing of the samples in a dry ice and acetone solution followed by storage of the specimens in the frozen state. The method was evaluated by first establishing the reproducibility of the chemical method used for blood ammonia analysis in 714 consecutive samples of dog blood which were analyzed in d...
