Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh suhu rendah dan lama penyimpanan serta interaksi keduanya terhadap mutu buah tin. Penelitian ini dilaksanakan di Laboratorium Hortikultura, Fakultas Pertanian Universitas Syiah Kuala, Banda Aceh yang berlangsung sejak Juni hingga September 2019. Penelitian ini menggunakan Rancangan Acak Terpisah (Split Plot Design) pola faktorial dengan 2 perlakuan yaitu suhu rendah dan lama penyimpanan. Suhu rendah dengan 3 taraf perlakuan yaitu 5ºC, 10ºC dan 15ºC dan lama penyimpanan dengan 3 taraf perlakuan yaitu 3, 6 dan 9 hari. Hasil penelitian menunjukkan bahwa suhu rendah berpengaruh terhadap uji organoleptik pada penampilan keseluruhan dan aroma. Lama penyimpanan berpengaruh terhadap uji organoleptik pada aroma, rasa serta tekstur. Terdapat interaksi antara suhu rendah dengan lama penyimpanan, perlakuan terbaik dijumpai pada kombinasi antara suhu 15ºC dan penyimpanan selama 3 hari.Organoleptic Test of Fig at Low Temperature Treatment Abstract. This research aims to determine the effect of low temperature and storage duration, as well as their interaction on low temperature and long storage of quality of figs. This research was conducted at the Horticultural Laboratory Faculty of Agriculture, Syiah Kuala University, Banda Aceh, from June to September 2019. This research used a split plot design with two treatments, low temperature and  storage duration. Low temperature with 3 levels of treatment that is 5ºC, 10ºC and 15ºC and storage duration with 3 levels of treatment that is 3, 6 and 9 days. The results showed that low temperature affected on organoleptic test on overall appearance and scent. Storage duration affected on organoleptic test on scent, taste and texture. There was an interaction between low temperature and storage duration, the best treatment was found in a combination of a temperature of 15ºC and storage for 3 days.

Sodium Loss

1. An investigation has been made of the factors which cause sodium loss from ammocoetes when they are immersed in de-ionized water at 1° and 10° C. 2. Sodium influx ceases when animals are first immersed in de-ionized water, but can recommence when the animal loses sufficient sodium to the environment. The concentration of sodium required for influx to take place decreases with succeeding periods of immersion in de-ionized water at 10° C. and reaches minimum equilibrium concentrations as low as 0.005 mM-Na/l. 3. Low temperature inhibits sodium influx and thus promotes net loss of sodium to de-ionized water. 4. Low temperature also decreases the initial loss of sodium to de-ionized water and probably lowers the permeability of the external surfaces of the animal to ions. This effect is small compared with the inhibition of ion uptake so that the combined result is to increase the net loss of sodium from the animal. 5. Since animals lose calcium to de-ionized water and show a decreased rate of sodium loss when calcium salts are added, it is believed that the high rates of sodium loss in de-ionized water are attributable to the effect of calcium on permeability. 6. Lack of calcium may also explain why animals which have been depleted of sodium by low-temperature treatment take up sodium much faster at higher temperatures from dilute Ringer solutions than from pure sodium chloride solutions. 7. When animals lose ions to de-ionized water at low temperature, sodium and chloride are lost from the extracellular space, whilst the muscle cells lose potassium. These ions are recovered into the extracellular space when animals are allowed to take up ions at 10° C. from diluted Ringer solution later.

Low Temperature Processing

The study was aimed at developing a technology for preparing various semi-finished products from pork meat using low-temperature processing "Su-Vid". The main physicochemical indicators, functional-technological and structural-mechanical characteristics of semi-finished products, the chemical composition of semi-finished products and finished products were identified and determined experimentally, and organoleptic analysis was carried out. The data indicate that the use of low-temperature processing significantly affects the characteristics of manufactured products, which improves its performance. In particular, pork semi-finished products prepared at low temperatures are characterized by the yield: steak – 93.9%, ribs – 92.6%, in comparison with the control regime, 7.5 and 6.2% higher. The complex of data obtained showed that the samples of semi-finished pork, according to the experimental regimes of heat treatment, in terms of safety, fully meet the requirements of TR TS 034/2013. Analysis of semi-finished pork products showed that products prepared using the Su-Vid technology had high organoleptic characteristics, taste and sensory characteristics. During the storage of semi-finished products, minor changes in proteins and fats, as well as organoleptic, sanitary and microbiological characteristics, took place. As a result, a bone steak was developed in the Caucasian marinade and pork ribs in the Monte Ritz marinade made using the Su-Vid technology. The results allow us to judge that this technology is quite promising and has a positive effect on the characteristics of manufactured products. The widespread introduction of this technology in the meat industry will allow the development of semi-finished products and products of high quality, nutritional and biological value compared to products manufactured by traditional methods, as well as reduce production costs.
