Naturally leading: a content analysis of terms, themes and word associations in Natural American Spirit advertising, 2000–2020

BackgroundNatural American Spirit (NAS) is a cigarette brand distinguished by supposed ‘natural’, ‘additive-free’ characteristics, marketing of which is tied to misperceptions of reduced harm. In 2017, NAS’s manufacturer agreed (with the Food and Drug Administration) to remove ‘natural’/‘additive-free’ from US marketing. Prior research has explored NAS marketing immediately post-agreement. This study sought to identify prominent post-agreement terms and themes and analyse how they had been used in pre-agreement ads.MethodsWe conducted a content analysis of NAS ads from 2000 to 2020 (N=176), documenting prominent pre-agreement and post-agreement terms/themes and examining how they are used in NAS ads. We coded for descriptors, themes, imagery and promotions, and extended prior research by analysing how leading post-agreement terms were used in conjunction and thematically associated with ‘additive-free’ and ‘natural’ before the agreement.ResultsResults indicated ‘tobacco and water’ and ‘Real. Simple. Different.’ increased post-agreement, as did environmental imagery. ‘Organic’ was prominent pre-agreement and post-agreement. The descriptors used most often in post-agreement ads almost always appeared in conjunction with (and were thematically linked to) ‘natural’ and ‘additive-free’ in pre-agreement ads.ConclusionsIn the years since the agreement, NAS ads have heavily relied on still-allowable descriptors that may invite reduced risk misperceptions. Notably, these descriptors were consistently used alongside the banned terminology before the agreement and presented as if affiliated conceptually, possibly prompting similar connotations. Findings indicate a continuing need for research into NAS advertising effects and a potential role for additional regulatory action.

PSXIII-24 Is it possible to finish beef cattle in feedlot and be environmentally friendly?

To improve production without affecting the environment, the objective of this research was to evaluate a natural additive to replace the conventional growth promoters in finishing beef cattle diets. 160 Nellore bulls were assigned into two treatments, where the only difference was the additive used: natural additive (Fator P - 600 mg/kg DM) and conventional growth promoters (25 mg/kg DM of monensin + 20 mg/kg DM of virginiamycin). The Fator P® is an organic additive certificated by IBD, which is a blend of the compounds; amino acids (lysine, methionine, and tyrosine), choline, minerals, probiotics and essential fatty acids (omega 3 and omega 6). The diet contained 14% CP and 76% TDN. Nellore young bulls (n = 160), weighing 433 ± 7 kg, with an average age of 24 months, were used. The feedlot facilities contained 16 collective pens, in which 10 animals were allocated. The animal performance was evaluated for 84 days, with 21 days of adaptation. Means were compared with 5% of significance. The conventional growth promoters reduced the dry matter intake. Natural 11.33 kg/day and 10.9 kg/day for the conventional. The conventional growth promoters reduced in 0.43 kg of dry matter intake (P = 0.042) or 0.1% of body weight (P = 0.001; 2.26% to 2.16%). No difference in average daily gain (P = 0.58). 1.655 kg/day for natural and 1.625 for the conventional. The feed efficiency ratio wasn’t different (P = 0.71), natural 146 g / kgMSˉ¹ and 148 g / kgMSˉ¹ for conventional. There were no difference in carcass yield (P = 0.89), mean 56.3%. The natural additives can improve the dry matter intake and can be used as an alternative to antibiotics in high concentrate diets for beef cattle in feedlot system. Thus, finishing beef cattle in the feedlot can be environmentally friendly.

Preservation of meat products with natural antioxidants from rosemary

Oxidative reactions can reduce the quality of meat products. Synthetic antioxidants can delay the formation of oxidation products but their use in muscle foods has been reconsidered among modern consumers willing to purchase clean label products. Rosemary is a relevant source of antioxidants that can be explored as natural additive in muscle foods. This review aims to provide an overview of the protective effect of rosemary active against the oxidative decay in meat products. The use of rosemary essential oil or extract can slow the progression of oxidative reactions and preserve redness, reduce the accumulation of primary and secondary lipid oxidation and protein oxidation products, and slow the increase of perceived rancidity in sensory analysis. These effects were reported during the storage of patties, burgers, meatballs, sausages, and nuggets. In this sense, rosemary extracts and essential oil can be explored as natural antioxidant in meat products.

Potential Activity of Albino Grifola frondosa Mushroom Extract against Biofilm of Meticillin-Resistant Staphylococcus aureus

Mushroom extracts are a rich source of natural compounds with antimicrobial properties, which are able to prevent, to some extent, the growth of foodborne pathogens. The aim of this study was to investigate the potential of extracts from albino Grifola frondosa (GF), commonly known as maitake, to inhibit the growth of some bacteria and the biofilm production by Staphylococcus aureus. We obtained not only a significant reduction of OD score between biofilm and biofilm plus albino G. frondosa extract group, but also a reduction of category of biofilm. In addition, we observed a significant presence of isolates with strong category for the biofilm group and a significant presence of isolates with absent category for the biofilm plus albino G. frondosa extract group. These results confirm that the use of albino G. frondosa extract reduces in significant way the presence of biofilm. Our results suggest and confirm that albino G. frondosa extracts could be employed as functional food and could be used as a natural additive for food process control and food safety.

Experimental Studies On Reduction of Nox Emission of Biodiesel Fuelled Engine Using A Novel Natural Additive

The world’s energy demand increases because of increase in human population. The conventional fossil energy resources will be depleted and burning of these conventional fuels increases greenhouse gases and causes global warming. These problems can be overcome using renewable alternative energy resources such as biofuels. In recent years biodiesel is considered as a renewable alternative to the fossil diesel. The utilisation of biodiesel as a fuel in compression ignition engine results in lower CO, HC and Smoke emissions as the biodiesel is an oxygenated fuel. The major problem with the biodiesel is its higher NOx emission and different techniques were used to minimise NOx emission. The use of synthetic and nano-metal additives to the biodiesel may affect the environment and hence it is necessary to identify non-toxic, low cost, biodegradable, and sustainable additives to reduce the NOx emission. Hence an attempt was made to use clove oil as a natural additive for the honge oil biodiesel as it has better antioxidant property. The engine tests were conducted with various dosages of clove oil such as 1000 and 2000 ppm and the engine load were increased with an increment of 25% up to full load. The addition of clove oil to the honge oil biodiesel significantly affects the engine NOx and clove oil can be substituted as an additive to reduce the NOx emission of the biodiesel fuelled CI engine and without altering the engine hardware. The clove oil enhances the oxidation stability of the honge oil biodiesel.

Improving the Quality and Durability of Restorative Coatings by Arc Deposition and Modification with Natural Additive Bentonite Clay

The study considers the possibility of improving the quality and service life of reducing coatings by arc deposition and modifying with natural additive bentonite clay. It has been established that when the modifier is introduced into the fluid bath during arc deposition, the phases and their interactions change. Introduction of the modifying additive bentonite clay significantly changes the crystalline lattice of the carbidephases. The optical-mathematical method revealed the absence of austenite and the pair interaction of ferrite-carbide during modification. The maximum proportion of phases corresponds to ferrite (33.8% -2 times decrease) and ferrite-austenite-carbide interaction (48.62% -2 times increase). The ferrite-austenite interaction increases almost 8 times during modification. The wear coefficient in this case is 2.2 times lower in comparison with the original steel 65Gand 1.4 times lower in relation to arc deposition with only T-620 electrode.
