This work proposes an electronic equipment which determines the marbling grade in beef rib eye according to the American grading scale using digital image processing and machine learning, achieving an 88.89 % coincidence level with grading done by beef specialists. Existing solutions which use image processing usually require calibration methods due to working in non-controlled environments. Furthermore, they only acquire the fat distribution from the longissimus dorsi muscle with an approximate accuracy of 80 %, without referring the distribution to any quality standard. In this work, meat samples are placed in a food grade stainless-steel enclosure with a touch screen and a digital RGB camera. The device acquires an image of the rib eye, which is then analyzed using techniques such as adaptive histogram analysis based on the HSV color model, histogram peaks detection for grayscale thre...

The fishing industry generates large quantities of by-products, most of which are not used and are therefore discarded. The objective of the present research was the elaboration of a pâté-type sausage from mechanically recovered meat of rainbow trout (Oncorhynchus mykiss). The meat was obtained from trout skelons, which were passed through a grinder and sprayed with a mixture of α-tocopherol (0.02%) and ascorbic acid (0.05%). The formulation of the pate was as follows: mechanically recovered trout meat (74.4%), salt (1.3%), sodium tripolyphosphate (0.8%), starch (2%), soy protein isolate (2.4%), margarine (16.7%), soy lecithin (1.9%), onion powder (0.2%), garlic powder (0.2%) and pepper powder (0.1%). Three formulations were prepared: PCR1 (80% cooked meat and 20% raw meat), PCR2 (90% cooked meat and 10% raw meat) and PCR3 (100% cooked meat). For each formulation, the following were e...

The current research aims to reassess no traditional meats that in sausage shape get to entry in the local market, according to their nutritional qualities, such as low cholesterol and high protein, which shows the alpaca meat against pork, and also revalue mutton. The presence of Gigartina chamissoi (seaweed) in the formulation is important as a source of iodine, complex polysaccharides (fiber) and natural gelling agents which increase its biological value. Gigartina chamissoi besides raise its nutritional value, constitutes a prebiotic product for counter propensities against cancer cells in tissues such as mucous (esophagus, stomach), glandular (breast) and glandularvessels (prostate). To this effect has been developed an experimental design allowing manufacture sausages in more optimal hygienic conditions. The proximal chemical analysis of the finished product (Table 9) showed that F...

Beef aging is a process that involves the interaction of enzymes and chemical transformations that directly influence changes in flavor and texture, which in turn can determine the sensory experience for guests. The purpose of this study was to compare, in terms of texture, the aging of beef brisket cuts through two techniques: with animal fat coating and dry aging, over a period of 21 days, and to determine the acceptability of end consumers. The cuts were stored under controlled temperature and moisture conditions (2 °C and 60 % relative moisture, respectively), with continuous monitoring to ensure food safety. Finally, they were cut into 2 cm thick steaks, fried to medium doneness with salt, and sensorially evaluated by a panel of 27 individuals. The results revealed an acceptance rate of 74.1 % for the meat sample aged with animal fat, surpassing the dry-aged sample (22.3 %) and the...

Mixed martial arts (MMA) has always been surrounded by controversy due to the unusual muscle development of its participants, so it is crucial to know the strategies that have been implemented to reduce doping cases. The main purpose of this paper is to describe the various cases of doping detected by USADA in UFC MMA participants. In addition, strategies that are being developed to reduce cases of positive doping are proposed. From the UFC USADA database, doping cases were extracted, obtaining the substance or substances involved; the formula, physiological effect and the athletes involved; the dates of the sampling; if it was out of competition or in-competition and the sanction time. The substances that were most involved were found to be Ostarine (22), Clomiphene (9), Diuretics (10) and Stanozolol (9). Some sanctions were diminished because they were treated with contamination of sup...

Language describes approach/avoidance intentionality by means of attitudinal verbs (e.g., accept vs. reject). The right superior temporal sulcus (rSTS) has been shown to be recruited in processing action goals and approach intentionality in social contexts. In this study, we examine whether transcranial direct current stimulation (tDCS) of this area improves the processing of attitudinal verbs (either of approach or avoidance) in the context of affirmative and negative sentences [e.g., Julio (did not)/included meat on the grocery list]. After being subjected to tDCS, 46 participants were given sentences for passive reading. Sentences were displayed in segments with a fixed time of exposition, and a verb, either the one mentioned in the sentence or an alternative one was displayed 1,500 ms after the sentence (e.g., included vs. excluded, in the example). Participants were told to read the...
