Partial size grading was applied to some varieties. Beans v;ere 

 "blanched at 212° f. 2 to 4 minutes, depending on the size and texture. 

 !To evidence of improper "blanching was obtained. Most of the "beans 

 had satisfactory to excellent quality when frozen dry or in 2-pcrccnt 

 "brine. 



Sweet Corn ; Eighteen varieties of sweet corn were -olanted on "^ebnaary 

 12, March 7, and March 11. Corn planted in I'ebr^uary produced most 

 heavily in this year's tests. In general, it may "be stated that resis- 

 tance to ear worm damage, as "orovided "by a lon-^ tight husk, appears to 

 'oe a reauisite for -^da-nta'bility unier south 'A'exas conditions. In these 

 preliminary tests the following varieties produced promising yields 

 of sweet Corn of satisfactory earning and freezing quality: Iowa hy'brids 

 191 X 194 8. 128 X 1071, 1612 x 1445. po9 .r 145, F51 x 145, and 04 x 145; 

 Georgia varieties 42_9 and 496, Sweet Sn ■'^lake,, H oney June and Sure 

 Cro-nner Sugar . 



Corn v;as husked, silkod and trimmed "by hand and "blanched in 

 steam, or "boiling water for 4 minutes, cooled, placed in the can and 



from the Iowa hy'brids compared favorably v/ith f^ncy commercial pac'xs 



Records of the Texas Ex-oerim.rnt Station include; weather, 

 prei^aration of soil, date and method of nlanting, crop management, 

 date of harvest, yield, nnd description of olants and crops. 



P:.ecords o" the U. S. Fruit and l^egetable Products Laboratory 

 include total yield, shrinkage after cleaning, trimming and sorting, 

 method of grading, time ?nd temperature of blanching, method of uack- 

 ing, freezing temperature and the flavor, color and texture of fresh 

 and frozen products before and after cooking. All products were 

 frozen in cans immersed in alcohol cooled to -40*^' ?. to -60*^ P. 

 vdth solid Carbon dioxide. 



SUMKASY; 



This progress report summarizes observations on the ca:i'"-ing, 

 freezing;, drying and fermentation of, and the recovery of by-oroducts 

 from, fruit and vegetable crops produced in Texas, 



Canning and freezing studies are 'n co-operation with the 

 Texas Experiment Station, and the waste ^.is-^)osal work is in co- 

 operation v.'ith the Texas State Board of Health. 



A new laboratory building ha? just been completed and now 

 eauipmcnt is being secured. It is proposed to extend the investi- 

 gation of the utilization of fruits and vegetables as rapidly as 

 facilities will permit.
