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.

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.

Higher salt intake is associated with the risk of cardiovascular and kidney diseases, hypertension and gastric cancer. Salt intake reduction represents an effective way to improve people’s health, either by the right choice of food or by a reduction of added salt. Salt substitutes are often used and also herb homogenates are treated by high pressure technology. Salt reduction significantly influences the shelf life, texture, pH, taste, and aroma of cheese. The composition of emulsifying salts or starter cultures must be modified to enact changes in microbial diversity, protease activity and the ripening process. The texture becomes softer and aroma atypical. In bakery products, a salt reduction of only 20–30% is acceptable. Water absorption, dough development, length and intensity of kneading and stability of dough are changed. Gluten development and its viscoelastic properties are affected. The salt reduction promotes yeast growth and CO2 production. Specific volume and crust colour intensity decreased, and the crumb porosity changed. In meat products, salt provides flavour, texture, and shelf life, and water activity increases. In this case, myofibrillar proteins’ solubility, water binding activity and colour intensity changes were found. The composition of curing nitrite salt mixtures and starter cultures must be modified.

It has been estimated that approximately 75% of the human’s sodium intake is added during industrial manufacturing. Processed meats can also contain relatively high amounts of saturated fats, and high levels of fat, associated with increased risk of obesity, diabetes and cancers, especially colon cancers. In contrast, dietary fiber intake (ex. inulin) has been associated with health benefits, including a suggested protective effect against colorectal cancer due to an inverse association with colorectal cancer risk. Nutritional and health concerns indicate that consumption of these two elements should be reduced. This study aimed to develop a ham with reduced levels of salt and fat. We added essential oils of oregano and rosemary to preserve the ham as a substitute for fat, for which inulin was also added. Six ham formulations were prepared (control, fat reduction + inulin, salt reduction, salt reduction + essential oils, salt reduction + no fat, and salt reduction + no fat + essential oils). The physical-chemical and microbiological quality parameters were evaluated. The addition of inulin did not interfere with the chemical composition of the formulated ham, presenting itself as a promising alternative for reducing the addition of fat in baked ham. The administration of essential oils in combination caused a significant decrease in native flora of cooked ham. These results suggest that a combination of essential oils and inulin may be a promising alternative in the production of meat products with lower salt and fat levels.

Sodium Consumption

Excessive sodium consumption is associated with adverse health effects. An elevated dietary intake of salt (sodium chloride) has been related to high blood pressure or hypertension, a major but modifiable risk factor for cardiovascular disease, as well as to other ill health conditions. In the present work, our aim was to describe the contribution of foods to sodium consumption within the Spanish population in a representative sample from the “anthropometric data, macronutrients and micronutrients intake, practice of physical activity, socioeconomic data and lifestyles in Spain” (ANIBES) study (9–75 years), to identify high consumer groups, as well as the major food groups that contribute to sodium intake in the Spanish diet. Intakes were assessed by 3-day food records collected on a tablet device. Sodium intakes across the ANIBES study population exceeded recommendations, as total intakes reached 2025 ± 805 mg of sodium per day, that is approximately 5.06 g/day of salt (excluding discretionary salt, added at the table or during cooking). Sodium intakes were higher in males than in females and within the youngest groups. Main dietary sources of sodium were meat and meat products (27%), cereals and grains (26%), milk and dairy products (14%) and ready-to-eat meals (13%). Given the established health benefits of dietary salt reduction, it would be advisable to continue and even improve the current national initiatives of awareness and educational campaigns and particularly food reformulation to decrease overall salt intakes across the Spanish population.

16S Rrna Pyrosequencing

ABSTRACTRaw sausages are perishable foodstuffs; reducing their salt content raises questions about a possible increased spoilage of these products. In this study, we evaluated the influence of salt reduction (from 2.0% to 1.5% [wt/wt]), in combination with two types of packaging (modified atmosphere [50% mix of CO2-N2] and vacuum packaging), on the onset of spoilage and on the diversity of spoilage-associated bacteria. After 21 days of storage at 8°C, spoilage was easily observed, characterized by noticeable graying of the products and the production of gas and off-odors defined as rancid, sulfurous, or sour. At least one of these types of spoilage occurred in each sample, and the global spoilage intensity was more pronounced in samples stored under modified atmosphere than under vacuum packaging and in samples with the lower salt content. Metagenetic 16S rRNA pyrosequencing revealed that vacuum-packaged samples contained a higher total bacterial richness (n= 69 operational taxonomic units [OTUs]) than samples under the other packaging condition (n= 46 OTUs). The core community was composed of 6 OTUs (Lactobacillus sakei,Lactococcus piscium,Carnobacterium divergens,Carnobacterium maltaromaticum,Serratia proteamaculans, andBrochothrix thermosphacta), whereas 13 OTUs taxonomically assigned to theEnterobacteriaceae,Enterococcaceae, andLeuconostocaceaefamilies comprised a less-abundant subpopulation. This subdominant community was significantly more abundant when 2.0% salt and vacuum packaging were used, and this correlated with a lower degree of spoilage. Our results demonstrate that salt reduction, particularly when it is combined with CO2-enriched packaging, promotes faster spoilage of raw sausages by lowering the overall bacterial diversity (both richness and evenness).IMPORTANCEOur study takes place in the context of raw meat product manufacturing and is linked to a requirement for salt reduction. Health guidelines are calling for a reduction in dietary salt intake. However, salt has been used for a very long time as a hurdle technology, and salt reduction in meat products raises the question of spoilage and waste of food. The study was conceived to assess the role of sodium chloride reduction in meat products, both at the level of spoilage development and at the level of bacterial diversity, using 16S rRNA amplicon sequencing and raw pork sausage as a meat model.

The lymphatic system is very important in the immunological activities of the body. Clinicians confirm the diagnosis of infectious diseases by palpating the involved cutaneous lymph node for changes in size, heat, and consistency. Clinical pathologists diagnose systemic diseases through biopsies of superficial lymph nodes. In many parts of the world the goat is considered as an important source of milk and meat products.The lymphatic system has been studied extensively. These studies lack precise information on the natural morphology of the lymph nodes and their vascular and cellular constituent. This is due to using improper technique for such studies. A few studies used the SEM, conducted by cutting the lymph node with a blade. The morphological data collected by this method are artificial and do not reflect the normal three dimensional surface of the examined area of the lymph node. SEM has been used to study the lymph vessels and lymph nodes of different animals. No information on the cutaneous lymph nodes of the goat has ever been collected using the scanning electron microscope.

This study was undertaken to estimate the contribution of meat and meat products consumption to the daily intakes of trace elements (Fe, Zn, Cu, Se), heme iron, and selected B vitamins (thiamine, riboflavin, niacin) in Italy. Meat and meat products were selected on the basis of their consumption frequency reported by the most recent nationwide dietary individual survey carried out in Italy (INN-CA study). The daily intakes of total iron and heme iron were 1.65 and 1.13 mg/person/day. Zinc intake was 3.65 mg/person/day. Beef made the main contribution to iron, heme iron, and zinc daily intakes. Copper daily intake was 107.3 mug/person/day, with meat products provided the highest contribution (40 mug/person/day). Daily intake of selenium (7.14 mug/person/day) was provided mainly by poultry consumption. Thiamine intake was 228 mug/person/day, and meat products were the main source (110 mug/person/day). Riboflavin intake was 136 mug/person/day, with both beef and meat products as the main contributors (40 mug/person/day). Niacin intake was 7.53 mg/person/day, and poultry was the main source (2.28 mg/person/day). Meat and meat products were a valuable source of micronutrients, supplying 47, 48, and 24% of zinc, niacin, and thiamin daily requirements, respectively, and over 10% of iron, copper, selenium, and riboflavin daily average requirement values of the italian RDAs calculated for the population involved in the survey (INN-CA study).
