Abstract

The study was designed to elicit some basic information on the effect of different pressing and scalding treatments applied to the curd with special reference to the standardization of Maraş cheese. For each experiment six different samples (IA, IB, IC, IIA, IIB, IIC) were used. The samples were manufactured experimentally by applying three different scalding treatments, 70 ± 1 ^oC/5 min. (A) , 75 ± 1 ^oC/5 min. (B) and 80 ± 1 ^oC/5 min (C), to each of two curds pressed for 1 h by 1:5 kg (I) and 1.5:5 kg (II) weights of milk used. All experimental samples were examined microbiologically, chemically and physically on the first, 15^{th}, 30^{th}, 60^{th} and 90^{th} adys of the ripening period in addition to the assessment of the sensorial characteristics of 30, 60 and 90-day-old experimental samples. During the ripening period no regular changes were found in the fat, moisture, ash, salt content and acidity, pH and a_w values of the samples, although moisture content increased by 1-4% at the end of ripening. It was determined that sample IB in group I had a high a_w value and the difference between IA and IB was significant at p < 0.05. Aerobic mesophilic and Lactobacillus microorganisms decreased in number at different rates toward the end of the ripening period, although the decrease was not considerable in the colony count of aerobic mesophilic microorganisms after the 30^{th} day of ripening. Sample IA had the maximum total sensorial score on the 30^{th} and 90^{th} days of the ripening period and IB on the 60^{th} day. It is concluded that pressing and scalding treatments applied to the curds slightly affected the chemical and physical characteristics and that treatments by pressing for 1 h by 1:5 weight of milk used and of scalding at 70 ± 1 ^oC for 5 min will give better sensorial quality characteristics, particularly with regard to appearance.
