A critical step in profitable post-harvest potato storage management is to cure tubers at appropriate temperatures long enough for rapid wound-healing to prevent disease and defect development, but not too long to jeopardize storage quality. A two-year storage study was conducted in macro-storage totes at the University of Wisconsin Hancock storage research facility to evaluate the effects of higher wound-healing temperatures (15.6 °C, 18.3 °C) imposed for different durations, and compare them to the U.S. potato industry’s standard practice (12.8 °C), on weight loss and frying quality of multiple processing potato varieties during long-term storage. It was found that in the experimental setting of this study, warmer wound-healing temperatures resulted in (1) less weight loss, particularly during the early storage season across varieties; (2) ameliorated senescent sweetening of the Snowden variety; (3) improved fry quality of the Russet Burbank variety; (4) and no apparent disease spread during long-term storage if tubers were harvested healthy out of fields. Overall, no significant difference was found between 15.6 °C and 18.3 °C regarding their treatment effects. Our conclusion is that compared to the current standard practice, higher wound-healing temperatures may have the potential benefits of improving potato storage quality while reducing the economic penalty associated with weight loss for specific varieties, but tubers should be healthy at harvest in order to gain the benefits. Further research is needed to test if those benefits of higher wound-healing temperatures hold true in large-scale commercial storage facilities.

The main problems of grape storage are berry dehydration and rot. One of the solutions to reduce rot and preserve the quality of grapes during storage is the use of aerosol treatment with calcium content before storing. The aim of the study was to evaluate the effect of physiologically active substances based on calcium in various concentrations on the quality and organoleptic characteristics of table grape cvs. ‘Italia’ during long-term storage. The effectiveness of the studied systems of treatment was evaluated according to the content of sugars and titratable acids, the activity of the redox enzymes of polyphenol oxidase and peroxidase, weight loss of bunch and organoleptic properties. The greatest effectiveness established by using preparation of Master Green Ca, Brentax KCa, and Brentax Ca (in concentration 150g / 20l). Experimental treatments significantly decreased the weight loss of bunch (less than 4%), and preserved organoleptic properties of berry at a high level (8.2-8.9 points). Decrease in the activity of oxidative enzymes had a positive effect on the quality of table grapes and contributed to its better preservation. The data obtained make it possible to rationalize the system of long-term storage of grapes by using of aerosol treatment with calcium-based preparation.

The methodology in Latvia forest industry provide to determine the quality of energy chips only in long- term storage places before selling. Due to the lack of hard empirical data about the quality parameters of energy chips in different phases of manufacturing process, this research paper consists of: - the identification and analyses of the factors that influenced the values of energy chips quality features such as: bulk density, moisture content, ash content, higher and lower heating value according to actual moisture content and per dry mass of the chips; - the methodology for determination the quality parameters of energy chips by analysis the wood moisture content and by choice the method of the manufacturing of energy chips.

Due to the fact that milk has a short shelf life, the issue of its freezing and long-term storage in the frozen state is relevant. A study was conducted on the effect of freezing on the milk quality after its defrosting of cows-mothers and cows-daughters of Red-Motley breed. As a result, it was established how milk quality indicators to change after five months of storage in a frozen state in cows of two age groups. A high correlation was established between quality indicators before and after freezing. The influence of the “freezing” factor on milk quality indicators was recognized statistically significant, the “generation” factor – not significant.

The problem of utilization or recycling industrial tobacco wastes is an important problem for tobacco industry. Economically preferable way for utilizing industrial tobacco wastes (tobacco scrap) is production smokeless products and hookah blends as wastes are utilized without special treatment. Monitoring of humidity and fractional composition of cut tobacco taken from tobacco rod/cigarette spoilage (tobacco scrap) is carried. Its long-term storage leads to increasing scrap and dust quantity. Researches on utilizing tobacco scrap for sniff and hookah blend production, which are considered to be less harmful compared to cigarettes, were carried. Chemical composition of American type tobacco and scrap was defined. Nicotine content varies from 0.9 to 2.4% and carbohydrates content – from 5.6 to 9.6%. Experimental samples of hookah blend were produced and their organoleptic and taste evaluation were carried. It was found that utilization of tobacco scrap is economically efficient for hookah blend production, as quality of final product made of leaf tobacco and tobacco scrap is similar. Experimental samples of sniff tobacco were produced in order to discover possibility of utilization industrial tobacco scrap for manufacturing this product. Consumer’s properties of sniff tobacco were evaluated by 100 points tasting protocol. This technology for sniff tobacco production from tobacco scrap allows manufacturing product of good quality, decreasing technological operations, rejecting stages of tobacco selection and its cutting and as the result decreasing cost of final product. The results of the research on utilizing tobacco scrap for hookah blend and sniff tobacco production proves optimality of recycling the tobacco wastes.
