Physical, chemical and texture characteristics of Aro cheese

Abstract

In 2016, Mexico's total annual production of cheese was 375,181 tons. Cheese is widely consumed among all socioeconomic groups, and the decision to purchase this product is based on income, with a wide variety of cheeses, brands, and styles available. The fresco cheese is the most popular type and is mostly produced according to traditional or artisanal methods in small family businesses, and small and medium-sized enterprises. It is made with the milk of the producers' livestock, giving it an added value. In Mexico, however, there is not enough scientific information related to the characterization of various dairy products of artisanal production, for example, Aro cheese. The aim of the present study was to define the physical, chemical, and rheological characteristics of the Aro cheese that is commercialized in Teotitlán de Flores Magón, Oaxaca, Mexico. Twenty-four samples of Aro cheese were collected in four establishments with high sales in Teotitlán de Flores Magón, Oaxaca, for analysis physical (Diameter, weight, height and color), chemical (pH, acidity, aw, chlorides, moisture, ashes, protein and fat), and texture (hardness, springiness, adhesiveness and cohesiveness). No difference was found in weight, diameter, height, and color (L* and b*). However, differences in hardness and cohesiveness were found. Although Aro cheese is characterized as an enzymatically coagulated cheese, pH values of 5.82 to 6.08 were recorded, and the data relating to moisture, protein, fat, and chlorides are similar to other Mexican fresh cheeses. The cheese of Aro that is commercialized in Teotitlán de Flores Magón, presents similar physical, chemical and texture characteristics to other fresh cheeses of artisanal production.

Karakterisasi Keju Dangke Menggunakan Enzim Papain Komersial Dan Perubahan Fisik Selama Penyimpanan

“…Keju segar memiliki kadar air sekitar 46-57%, kadar protein 15-21%, kadar lemak 20-29%, kadar garam dari 1-3% dan pH pada kisaran 5,3-6,5. Keju segar dibuat dari susu murni dan memiliki rasa yang mirip dengan susu segar, walaupun kadang-kadang sedikit asin (González et al, 2018).…”

Correlation between free fatty acids content and textural properties of Gouda cheese supplemented with denatured whey protein paste

“…The results obtained illustrate various texture observations that provide a strong correlation with those obtained by sensorial methods and are one of the most common tests for assessing the texture of cheese. Hardness, springiness, adhesiveness, and fracturability are the parameters most commonly used for TPA cheese (González et al 2017 ).…”

Traditional Cheese Produced in Fogo Island - Cape Verde: Physico-Chemical, Sensory, Hygienic and Safety Characteristics

“…However, due to the coagulation in cheese production, pH values are expected to be lower than milk since the pH values decrease because of the presence of acid lactic bacteria that resist pasteurization or contamination after pasteurization González et al (2017). In this study, the values of pH (5.68-6.19) were lower compared to raw milk.…”

“…The acidity of coalho cheese had a variation of 6.4 to 11.1 mLNaOH1N/100g. As described by González et al (2017), this range of acidity is normal in fresh cheeses with a short ripening time. In general, increasing storage time leads to increased acidity in cheeses, due to the presence of microorganisms Pinho et al (2004).…”
