Effects of medium voltage electrical stimulation on initial pH decline and quality parameters during ageing and frozen storage of Nellore beef.

This study aimed to evaluate the influence of medium voltage electrical stimulation (ES) at three different intensities, 200 V (Treatment 200 V, T200), 300 V (Treatment 200 V, T300), and 400 V (Treatment 400 V, T400) on the initial pH decline in post mortem muscle and the quality parameters on M. longissimus thoracis - Nellore beef, both throughout the ageing process and during frozen storage. The colour, cooking loss, and shear force parameters for samples of aged beef were determined.

Meat with edible coating: Acceptance, purchase intention and neophobia.

The acceptance of a new product depends on its sensory quality and consumers' physiological and psychological aspects. The fear of consuming foods processed by new technologies is an example. This study aimed to investigate the overall acceptance and purchase intention of chitosan-coated beef and lamb meat in blind and informed conditions and to estimate the psychometric properties using the Food Technology Neophobia Scale (FTNS).

Consumers' Attitudes toward the Use of an Edible Coating for Lamb Meat According to Label Information.

The use of edible coatings in meat is currently being investigated in several studies. However, consumers' attitudes toward this technology are not clear. This study evaluated consumers' intention to purchase vacuum-packaged meat with a chitosan coating based on the label information.

Effects of freezing and thawing on microbiological and physical-chemical properties of dry-aged beef.

This study evaluated the effects of freezing, prior to and after dry aging, on the microbiological and physical-chemical quality of beef. Strip loins (n = 24) from 12 carcasses were assigned to four treatments: non-frozen dry aging (Dry); dry aging, steak fabrication, freezing and slow thawing (Dry + ST); freezing, fast thawing (FT; 20 °C/15 h) and dry aging (FT + Dry); freezing, slow thawing (ST; 4 °C/48 h) and dry aging (ST + Dry). Freezing conditions were - 20 °C/28 days and dry aging conditions were 2 °C/70% relative humidity, for 28 days.

Heat shock and structural proteins associated with meat tenderness in Nellore beef cattle, a Bos indicus breed.

Nellore beef cattle, a Bos indicus (Zebu) breed, is well adapted to tropical conditions and has allowed Brazil to become one of the largest producers of red meat. Nevertheless, B. indicus breeds are reported to have less tender meat than Bos taurus.

Calcium and potassium content in beef: influences on tenderness and associations with molecular markers in Nellore cattle.

Calcium (Ca) and potassium (K) are essential nutrients in animal nutrition. Furthermore, the Ca content can influence meat tenderness because it is needed by the proteolytic system of calpains and calpastatins, major factors in postmortem tenderization of skeletal muscles. K content, which is needed for muscle contraction, can also affect meat tenderness.

Oxidative stability of fermented goat meat sausage with different levels of natural antioxidant.

Goat meat was used for fermented sausage processing. The oxidative stability of the fermented goat meat sausage, containing two different levels of natural antioxidant (rosemary-Rosmarinus officinalis), at room temperature, was evaluated by way of periodical analyses for thiobarbituric reactive substances (TBARS), overall acceptance and descriptive sensory profile, for 90 days. The initial values for TBARS indicated that lipid oxidation occurred during the processing of the fermented sausages.
