There have been organoleptically and physically-chemically examined twenty-five samples of pork semi-manufactured products (minced and salted pork, in different stages of tendering process) used in the manufacturing process of some meat products in casings. During the salting and tendering process we noticed a pH increase, total and protein nitrogen decreases proportionally with the proteolytic degree, respectively, the degree of aging of meat. The quantity of water and nitrites decreases while salt content increases proportionally with the water content decrease. These values limit the period of the tendering process at maximum 72 hours, the optimum period being considered as 48 hours, the storage conditions being at +2…+4 Celsius degrees.

Effects of seven different solutions prepared from various additives (carrageenan, konjac flour, phosphate, yeast extract, xanthan gum and maltodextrin) were used to test for the first time in the marination of experimental seafood. The additives were added into the marination solutions and the samples were analyzed before and after marination. Statistically, the experimental solutions did not cause significant changes in pH, acidity and salt content of the samples (P < 0.05). The highest weight gains were obtained from the solution which contained 0.1% of konjac flour (E425 I) as 4.01, 5.21, 4.61 and 4.88 % in the mussels, big squids, diced squids and small squids, respectively. However, this solution was not preferred by the panellists because of its sticky texture. Inversely to red meat products, the solution containing phosphate caused weight loss during marination. The results indicate that the solution containing 0.2% carrageenan LM (low methoxyl) was the best solution in the marination process. Dipping into this solution caused weight gains of 4.69, 2.98, 4.04 and 2.78% in the big squids, the mussels, the small squids and the diced squids, respectively (P < 0.01). The organoleptic properties (mouth feel, flavour and softness) of mussels and squids were also improved by carrageenan LM addition.

Animal origin foods are widely distributed and consumed around the world due to their high nutrients availability but may also provide a suitable environment for growth of pathogenic and spoilage microorganisms. Nowadays consumers demand high quality food with an extended shelf life without chemical additives. Edible films and coatings (EFC) added with natural antimicrobials are a promising preservation technology for raw and processed meats because they provide good barrier against spoilage and pathogenic microorganisms. This review gathers updated research reported over the last ten years related to antimicrobial EFC applied to meat and meat products. In addition, the films gas barrier properties contribute to extended shelf life because physicochemical changes, such as color, texture, and moisture, may be significantly minimized. The effectiveness showed by different types of antimicrobial EFC depends on meat source, polymer used, film barrier properties, target microorganism, antimicrobial substance properties, and storage conditions. The perspective of this technology includes tailoring of coating procedures to meet industry requirements and shelf life increase of meat and meat products to ensure quality and safety without changes in sensory characteristics.

Abstract Objective: To assess the contribution of different food groups to total salt purchases and to evaluate the estimated reduction in salt purchases if mandatory maximum salt limits in South African legislation were being complied with. Design: This study conducted a cross-sectional analysis of purchasing data from Discovery Vitality members. Data were linked to the South African FoodSwitch database to determine the salt content of each food product purchased. Food category and total annual salt purchases were determined by summing salt content (kg) per each unit purchased across a whole year. Reductions in annual salt purchases were estimated by applying legislated maximum limits to product salt content. Setting: South Africa Participants: The study utilised purchasing data from 344,161 households, members of Discovery Vitality, collected for a whole year between January and December 2018. Results: Vitality members purchased R12.8 billion worth of food products in 2018, representing 9,562 products from which 264,583 kg of salt were purchased. The main contributors to salt purchases were bread and bakery products (23.3%); meat and meat products (19%); dairy (12.2%); sauces, dressings, spreads and dips (11.8%); and convenience foods (8.7%). The projected total quantity of salt that would be purchased after implementation of the salt legislation was 250,346 kg, a reduction of 5.4% from 2018 levels. Conclusions: A projected reduction in salt purchases of 5.4% from 2018 levels suggests that meeting the mandatory maximum salt limits in South Africa will make a meaningful contribution to reducing salt purchases.

Physiological Quality

Studies of seed physiological processes represent the starting point for the sustainable utilization of native or cultivated plant species from the caatinga biome for which germination studies are still scarce. In order to determine adequate methods for the conservation of Gliricidia sepium seeds, the physiological quality of propagules exposed to different conditions and times of storage were examined. Recently collected seeds of G. sepium were analyzed immediately, while the other sample was stored for three, six, nine, or twelve months in plastic or paper bags under refrigeration or at room temperature for further analysis. The germination rates of seeds from each storage regime were determined and these rates compared to their water content. It was observed that germination capacity was directly related to changes in seed humidity. Storing seeds in plastic bags yielded the best conservation, mainly when they were stored at low temperatures. However, even at temperatures near 25°C it was possible to prolong seed viability when their water content was controlled through the use of impermeable packing.

This paper describes the preliminary results of my PhD research within the ERC pro­ject “HisTochText”. The aim is to perform macroscopic analyses of archaeological papers from the Pelliot Collection. They are stored in the National Library of France (Bibliothèque nationale de France). Most were discovered in the oasis kingdom of Kucha, inscribed in an ancient Indian writing, brāhmῑ. The language was unknown in France. Kucha was a meeting place for many influences both western and eastern, insofar as paper analysis seeks to determine technological influences and local adaptations. Macroscopic analyses rely on traces found in the material of the paper which may be the result of the many stages in the life of the document: the raw material, the manufacturing process, the conditions of use and the storage conditions, both ancient and modern. To this day 350 fragments have been observed. Little is known about papermaking in Central Asia. As a consequence, every shred of information must be examined in order to deter­mine the differences from and similarities to paper manufacturing in Xinjiang.

In the cultivation of milkfish, water quality is very concerned about in order to minimize fish mortality when cultivated. Several important factors in the cultivation of milkfish are the level of salt content in the water, temperature and pH. Currently, farmers monitor water quality manually by coming directly to see water quality. If there are dead fish, the cultivator will replace the new water. This will have an impact on fish production which will decrease. The milkfish pond uses brackish water for pond waters. The salt content is between the sea water content and the fresh water content. The grade level may change from season to season. This change is due to biological processes that occur in these waters as well as the interaction between pond waters and the surrounding environment. The results showed that the results of the design of the salt concentration monitoring system in the milkfish ponds that have been carried out using Arduino Uno, conductivity sensors, pH sensors, temperature sensors, wifi modules, Mi-Fi and Smartphones to access android applications. The results of testing the microcontroller functionality that have been made are in accordance with the design and are running well. The system designed to transmit information in the form of salinity values, pH sensors, temperature sensors and TDS values ??with sensor accuracy that is linear with measurement results using conventional measuring instruments with the highest error values ??of 1.3%, 2.06%, 0.702% and 1.5 respectively. %.

High sodium and fat contents are cause of concerns for industries and consumers of meat products. Direct reduction of NaCl and fat is a useful strategy to understand how these ingredients interfere with the quality parameters of an emulsified meat product and how to reduce them without significant changes from the original product. The aim of this work was to understand salt reduction in fat-reduced (10 g fat/100 g product) hot dog sausages. Five NaCl concentrations were tested: 1% (F1), 1.25% (F1.25), 1.50% (F1.50), 1.75% (F1.75) and 2% (F2 – control). Proximate composition, sodium content, water activity, pH, emulsion stability, color, texture, scanning electron microscopy results and sensory attributes (just-about-right and acceptance tests) were assessed. Emulsion stability decreased ( P < 0.05) with salt reduction. Salt reduction increased water activity. Microscopic images showed a more compact matrix with the decrease in salt content. Sausages with the minimum (F1) and maximum (F2) amounts of salt were less accepted by consumers. A reduction of 26.8% of sodium can be obtained (with the formulation F1.25), allowing the labeling of sodium-reduced sausage and with acceptance by consumers.
