Abstract: NOVA, LEA JERMOZA G., Applied Research IV (General Science Curriculum). Don Severina Agricultural College, Indang, Cavite, "PHYSTCO- CHEMICAL CHANGES AFTER HARVEST GF DIFFERENT VARIETIES OF ASPARAGUS SPEARS ''. Adviser: Prof, Josefine A. Viado. Co-Adviser: Ms. Joriza U. Florida The study entitled "Physico-Chemical Changes After Harvest of Different Varieties of Asparagus Spears' ' was conducted to identify the physical Chemical changes after harvest of different varities. Of asparagus Spears. This study was conducted at the Research Center of the Don Severino Agricultural College from April 1996 toa February 1997. Asparagus Spears Samples of different varieties -- Mary Washington, Horlim, and UC 157 Fyo~ Were used. They were subjected to four treatments. Ty - no storage period, Tg - 3 days of storage, Ta oo7 10 days of storage, and Tg - 15 days of storage in the refrigerator with potassium permanganate. Samples were evaluated by 10 non-smoking Panellists based on its color, texture, flavor, off- flavor and general acceptability. It was also Subjected for analysis of its pH, fiber content, TTA, T8S and moisture content. The study revealed that duration of storage affects the physical properties and chemical Compositions of asparagus spears. However , the sensory attributes of spears freshly harvested and stored did not show significant differences among Samples. Results also revealed that asparagus spears stored within 18 days remained acceptable, although Physical and chemical changes had occurred on the Samples, Based on this study, storing of asparagus Spears up to 15 days is recommended.
